What matters should Ningxiang Jiazhuang Company pay attention to in house inspection?

Key points of house inspection when handing over the house

Let's talk about the overall process first:

Check the preliminary information-get the key-check the house (inside and outside)-pay the money and sign the documents.

Previous information:

Check three books, one certificate, one form and five necessities.

The residential quality guarantee (take away),

Residential instruction manual (take away),

Construction engineering quality certificate,

"One certificate" refers to the comprehensive acceptance certificate for the completion of real estate development and construction projects.

"Table 1" refers to the completion acceptance record.

You can also check the auxiliary charts such as area measurement table, pipeline distribution map, household inspection handover table, building acceptance record table, technical report of commercial housing area mapping, and household acceptance table of residential engineering quality. See whether the commercial house delivered to you is consistent with the commercial house signed in the contract and whether its structure is the same as the original design. Whether the housing area has been measured by the real estate department and whether it is different from the contracted area. The domestic water supply system of high-rise residential buildings must have a water certificate issued by the health and epidemic prevention department and a fire acceptance certificate issued by the fire department.

Get the keys. In the general process of repossession, the owner will urge the owner to pay the property fee and other related expenses before the house inspection. The owner can communicate with them and pay the fee after acceptance. To get the key from the property office, there should be several keys, such as floor key, access control key, email key, etc.

Note: Free, unsigned, priority room.

After finding the problem, you can't pay or sign. The house should be repaired first, and at the same time, evidence should be obtained to lay the foundation for future evidence collection, especially to keep a good record of house inspection.

Check the house on site. It is divided into eight steps: internal inspection 1 1 and external inspection.

A. Internal inspection of the house (step 1 1): Most people mainly check this, starting with keys, entrance doors, internal doors and windows, walls, floors, ceilings, smoke exhaust ducts, heating, gas, strong and weak electricity, and water supply and drainage.

B. External inspection of the house (8 steps): Most people don't check this, such as supporting facilities, greening, facade, unit doors, stairs, elevators, interior decoration and fire protection.

Sign relevant documents and pay reasonable fees.

When signing the owners' convention and the preliminary property management contract, be optimistic about the terms and never give up your rights.

The reasonable expenses here include: the property management fee must be approved by the price bureau, the decoration deposit, the garbage clearing fee and so on.

Tools needed for house inspection

1. General auxiliary tools:

Notebook and fountain pen: used to record the problems found in house inspection.

Chalk or sticker: It mainly marks the place where the problem is found by drawing a circle.

Camera or recording pen: mainly used to record the whole inspection process and can be used as evidence;

Calculator: You can calculate the area or something.

2. Common detection tools:

Folding ladder: used for climbing.

Small mirror: look at the part that cannot be directly observed.

Dry battery: test doorbell

Small hammer: check the floor, walls and other empty drum problems.

5m tape measure: measure the length (laser rangefinder is recommended).

25 ~ 33 cm triangular ruler: measure internal angle, etc.

Double-headed and triple-headed cuttings with indicator light

Weak current connectors such as telephone, TV and broadband.

Small bucket, multi-purpose screwdriver, flashlight, lighter, cigarette, table tennis, ball, string, unused paint brush, plastic bag, sand, transparent water pipe with a length of 15-20M.

Internal inspection steps: from outside to inside, from low to high, from bright to dark.

First, you need to choose the correct key.

Second, check the security door (that is, your door)

Third, check the internal doors and windows.

Fourth, check the indoor walls.

Fifth, check the ground.

Six, check the ceiling (the top of the room, some places called the ceiling)

Seven, check the flue, exhaust.

Eight, check the heating (forget Siyang, skip)

Nine, gas (the same as natural gas)

First, you need to choose the correct key.

You can keep this as long as you can open the door. Anyway, the locks have basically changed after the renovation. In addition, it is estimated that Siyang will not have too advanced locks.

Second, check the security door (that is, your door)

Then began to check the security door. The contents and methods of inspection are as follows:

1. Visually check whether the door is horizontal and vertical and whether the door is parallel to each side of the door frame.

Insert the key into the lock to see if it is flexible and secure.

Under normal circumstances, our security doors are hinged doors, that is, doors that turn to open. Open the door, whether it rotates freely and whether the switch is flexible. After the normal security door is opened, it should be opened at any position and parked at any position. If the door closes itself after opening, it means that the door is not installed correctly and tilted. At the same time, check whether there is a gap in floor decoration between the door and the ground, otherwise it will be difficult to open the door after laying bricks or carpets.

Shake the door properly to see if it is installed firmly.

5. Check whether the front and back of the door are clean and smooth, and whether there are any defects such as scratches, bumps and deformation.

6. Put it on the top and bottom of the door with a small mirror, and check whether these invisible places have been painted or not.

7. Open a small crack in the door, then put a flat piece of paper in the crack of the door, then close the door and take out the paper. If it is easy to take out without blocking, it means that the sealing performance of the door is not very good. This test should be carried out from top to bottom. At the same time, after the door is closed, listen to what is going on outside. It is best to talk alone outside and test the sound insulation effect inside.

8. Check the doorbell of the security door (if there is one on the door), bring two 5th batteries, and test whether the doorbell doesn't ring or keeps ringing.

9. Check the cat's eye (if there is one on the door): see if it is loose, unclear, incomplete in vision or unable to see clearly due to foreign objects.

Third, check the internal doors and windows.

After entering the door, the most convenient thing is to look at the internal doors and windows first, and at the same time, you can ventilate the room by the way when checking. The inspection methods of inner hinged doors and hinged windows (if there are hinged doors and windows, K manufacturers generally don't install them) are basically the same as those of the above-mentioned hinged security doors, so I won't repeat them here. Here is mainly about the acceptance of the doors and windows of the inner slide rail. Sliding rail doors and windows that are horizontally pushed and pulled are commonly called "sliding doors" and "movable windows". This is what we will check next, and some of its points are the same as those of checking hinged doors and windows.

1. Visually check whether the sliding door and movable window are horizontal and vertical, and whether the door is parallel to the edges of the door frame, window and window frame.

2. Check whether the rotary lock of sliding doors and windows is flexible and flexible, and check whether the screws of the rotary lock are missing.

3. Open the sliding doors and windows to see if they slide freely and collide. If there is a screen window, it depends on whether the screen window is in good condition and whether there are obstacles in pushing and pulling. Pay special attention to whether the anti-collision strip is installed, otherwise it is easy to damage the lock.

4. Shake the sliding door, window, window frame and door frame with appropriate strength to see if they are installed firmly.

5. Check the movable door and window glass for cracks, quality problems, clean, smooth surface, uniform color, scratches, bumps and deformation. Whether the frame is rusted, and whether the combination of glass and frame is good. If some families use hollow double-layer glass, special attention should be paid to whether the inner hollow layer of the two layers of glass is clean. This part can only be cleaned by changing the glass.

6. The key point of moving doors and windows is its waterproof seal. Should focus on observing whether the sealant is flat and firm, whether the sealant surface is smooth, straight and crack-free, and whether the joints between walls, windows and doors are tightly blocked. Besides, we should not only look inside, but also lean out to look outside. It's best to check it right after the heavy rain.

7. Push-pull doors and windows should be equipped with anti-blocking caps to prevent foreign bodies from blocking drainage when it rains, resulting in water entering the window. Whether the set drainage hole is unobstructed, pour water into the box with a small cup to see if it can be discharged smoothly.

8. Check whether the sealing performance of sliding doors and movable windows is good when they are closed. Then stick a long piece of paper on the seal, close the door, press the paper and pull it out, and carry out multi-point test to see if the pressure of the sealing strip is uniform. At the same time, listen to the external noise and try its sound insulation effect.

9. Check the sliding doors and windows, but also look at the level difference between the wall inside and outside the frame and the ground plane. Generally, it is required that the outer side is lower, inclined outward or at a certain angle with the floor drain to prevent backflow and leakage.

10. The windows facing the corridor should be equipped with security nets.

1 1. Open all doors and windows in the room except the security door, let the air circulate freely, feel the ventilation effect of the house, and record it in a notebook or paper to prepare for the future ventilation design. After ventilation, close the doors and windows to the normal size, so that there is basically no wind in the room, just like the feeling at home at ordinary times.

Fourth, check the indoor walls.

It's best to go when the weather is bad.

1. Let's look at all indoor walls with naked eyes first, to see if there are any scratches, cracks and water stains on the walls, and if there are any peeling, powdering and bursting of the walls (quicklime is not stirred well when it is made into hydrated lime, and it will burst when it is dried on the walls). If there are cracks, use vernier caliper or feeler gauge to measure the size of the cracks.

2. Whether there is a reserved air-conditioning pipe hole on the wall, and whether there is water stain at the pipe hole. If there is, the angle of the pipe hole is not up to standard.

3. Check the insulation layer of the wall. Whether the walls in the room are dewy in winter (similar to bottled beer being iced in summer, and there are water drops on the outer wall of the bottle at room temperature) must be a problem with the insulation layer of the wall.

4. Check whether the wall is empty. Knock all the walls with a small hammer (hammer) weighing 10 to 50g (select as many points as possible, and don't miss the joints between walls, floors and top surfaces), and listen to the sound of "empty". If there is, it means that the cement mortar here is not evenly spread or the dosage is not enough, and the plastering layer of the inner wall is partially cracked and sanded, which all indicate the quality of the house. If you hear a dull thump, it means there is not much problem with the quality. It is important to check the sides of the windowsill, or the middle of the wall, where empty drums are frequent. If you don't have a small hammer at hand, you can also use an ordinary sledgehammer instead, but you should pad several layers of paper in advance and tap gently to avoid leaving marks on the wall.

The empty drum area is below 1.5cm× 1.5cm, which will not have much influence on the owner's decoration. If it is found that the empty drum area is large (when it exceeds 5%, the hard standard is unqualified), then you should ask the developer to remove all the original cement surface and waterproof putty scraped for you. Generally, when repairing, remove the wall surface with an area twice as large as the empty drum area, otherwise it will not be long before the empty drum part of the cement surface and waterproof putty will collapse in a large area.

Regarding the empty drum problem, Jiangsu Province's Code for Acceptance of Residential Engineering Quality stipulates that the empty drum area is not more than 400cm2, and no more than two places in each natural room (standard room) can be ignored.

5. When testing the wall flatness, the allowable civil error is 1cm, but it is generally out of tolerance. Generally speaking, there are two methods:

A. Local observation method, that is, use1-2m guiding rule and long ruler (or special ruler with level) to check whether it is flat against the wall. If the contact surface is tight and seamless, the flatness is qualified. It can also be replaced by a straight board or square wood with a length of 1.5-2 meters. Pay attention to measure at least the horizontal and vertical directions. Of course, you can also choose random directions and choose as many different walls as possible.

B. Overall observation method: hold a flashlight (the stronger the light, the better) and point it at the bottom of the wall and shine upward. Shaded parts are problematic. For uneven walls, the owner can re-smooth them by scraping putty during decoration.

6. Check the inclination of the wall, tie a small ball with a string, put the ground down against the wall and check the inclination of the wall.

7. Measure the perpendicularity of the Yin and Yang angles in the corner. The internal angle of a wall refers to the concave angle (also called internal angle). The external angle of the wall refers to the protruding angle (also called external angle). Such as the angle between the window opening and the wall. Measure the inner angle with a triangular ruler and the outer angle with a T-square. Professionals use laser scriber to detect the perpendicularity of yin-yang angle.

8. Confirm the positions of indoor load-bearing walls, counterweight walls, non-load-bearing walls and lightweight walls. One is to hit the whole wall with a hammer. If there is a buzzing echo, under normal circumstances, this wall is not a load-bearing wall. Another method is to confirm with the developer. It is generally believed that light structural walls, such as light steel keel, gypsum board wall or cement board wall, can be removed as partitions, and other walls, including counterweight walls, cannot be removed, otherwise they will have to be redone or everyone will bear the consequences when an earthquake occurs. For the semi-brick wall of the bathroom, if the supporting beam supporting the wall is designed in the floor structure, it can be removed, otherwise it cannot be removed. But even if it can be removed, the waterproof layer should be prevented from being destroyed, so it should be waterproof again.

9. If there are wall tiles on the wall, basically repeat the above steps and see if the tiles are flat, empty, defective and tight.

10. If there are railings indoors, check whether the railings are firm, rusted, smooth and scratch your hands!

Fifth, check the ground.

1. Visually check whether the floor is cracked, and whether the height difference between the bathroom and the living room floor is about 2cm. At present, some kitchens in some houses also have height difference requirements, and some K merchants even use the height difference method, but the height difference in the bathroom is necessary. In some areas, kitchens also have rigid height difference regulations, and balconies look as flat as indoors without mandatory height difference regulations. Then use shoes to feel whether there is sand on the ground (rub the ground with shoes to see if there is a feeling of rubbing sand, and if there is, it is unqualified. )

2. Use a small hammer to detect whether there is an empty drum on the ground again.

3. To detect the flatness of the ground, the local ruler method and the overall lighting method can be used to measure the flatness of the wall (a special ruler with a level can be used).

4. Detecting the horizontal error of the ground is to measure the horizontal error between the indoor ground farthest from the door and the ground inside the door, which can reflect the building quality of the developer from one angle. Use a transparent flexible water pipe about 15-20m long, and basically fill it with water. Then let one person hold one end of the nozzle to his chest and stand at the door, and the other person hold the other end to his chest and stand at all the places farthest from the door. Then the third person measures the heights from two places to the water surface of two nozzles, and the difference between these two heights is the horizontal error of the ground. Generally speaking, the error of high-quality houses is within 0.5cm, and it is normal if the difference is about 2cm, and 3cm is the maximum acceptable range. Beyond this range, the quality of the house is too poor. This step is recommended to be done at the time of waterway acceptance, so as not to make the house full of water. )

5. Check the fine seam at the angle between the ground and the wall, clean the building dust at the angle between the ground and the wall with a broom or an unused paint brush, and check whether there are cracks, potholes and exposed steel bars after cleaning. At the same time, check whether the ground is perpendicular to the internal angle of the wall, and the method is the same as that of the internal angle detection of the wall.

6. Detect the slope of the ground in the area with floor drain. Where there is a floor drain, the ground needs to have a certain slope, so that the water on the ground can flow in smoothly and then be discharged. The slope is too large or there is no slope. Floor drains usually appear in bathrooms and balconies, and in the kitchens of some houses. Let's take the bathroom for example. The test method is to put table tennis at the door of the bathroom and at the root of the wall, and push it gently to see if it rolls to the floor drain. If there is a problem with the slope, the construction party is required to rectify it in time, shovel off the existing plastering layer, and plaster it again after making a waterproof layer. The slope should face the floor drain, and the highest outlet should not exceed the living room floor.

7. Check whether the ground with waterproof layer leaks. Generally, areas with floor drains have waterproof layers. Of course, you can also ask the development bank. Fill a plastic bag with sand and put it on the floor drain, and then store a layer of water about 2cm in the bathroom. After 24 hours, go to the bathroom of the corresponding lower-level household to see if there is any water leakage at the top. This test is best carried out at the same time with the upper-level residents, so that it can not only detect whether the floor of the bathroom leaks, but also detect whether the top of the bathroom leaks. The water pipes in some houses are far away from the bathroom, and there is no faucet in the bathroom during the embryonic period. At this time, the water pipe just now came in handy again. In addition, the floor of the washing machine must be waterproof.

8. Check whether the ground with waterproof layer will accumulate water. After the above water leakage detection, you can let the water go. At this time, you can observe whether there is water on the ground. Qualified ground can't have water, because the floor drain is the lowest place in the bathroom. But the blank room can be put low, because there is a certain height of pavement around the floor drain, which is the ground that needs to be treated during decoration. (Steps 7 and 8 can be performed after checking the waterway. )

9. The detection methods of floor tiles are basically the same. At the same time, it depends on whether the floor tile is flat, whether there is empty drum, whether the brick surface is defective and whether the brick joints are tight.

10. Roughly measure the length of each wall with a tape measure and record it on your own sketch to calculate the actual use area of the house. Generally, there are many cases where the internal area decreases and the pool area increases. When closing the house, confirm whether the attached drawings of the sales contract are consistent with the actual situation, whether the structure is the same as the original design, whether the house area has been measured by the real estate department, and whether it is different from the area agreed in the contract. (Check the sales contract first to see if there is any error, generally 3%. 3% or less is not considered, and the excess is treated. It is recommended to contract specification error 2%, but it is better not to exceed 5%. ) The contract signed by both parties shall prevail.

Check the ceiling

The acceptance of ceiling is similar to that of floor and wall.

1. Let's visually check whether there are pits, leaks, cracks, powder falling and mildew.

2. Select multiple points, and use a small hammer to detect the hollowing of the ceiling after climbing the ladder.

3. To detect the flatness of the ceiling, the local ruler method and the overall lighting method can be used to measure the flatness of the wall and the ground (a special ruler with a level can be used).

4. Check the height of the floor and the levelness of the ceiling (except for rooms with floor drains). Measure 5 points in each room with a tape measure. Generally, four corners (the internal corners of two walls) and the center of the house are selected for measurement. It's best to measure all the rooms in this quantity. The height above 2.65 meters is acceptable, and the height difference should be within 2cm. Professionals can use laser rangefinder for detection.

5. Check whether the ceiling is perpendicular to the internal angle of the wall, and the method is the same as the internal angle detection of the wall.

Seven, check the flue, exhaust.

1. Visually check whether there is a check valve at the smoke crossing, then climb the ladder and check whether there is construction waste in the flue and exhaust passage with a flashlight or emergency light.

2. Check the ventilation of the above pipes, climb the ladder, light the paper with a lighter until it smokes, put it under the smoke crossing and the exhaust crossing 10 cm, see if the smoke rises to the smoke crossing, and immediately turn around and suck it away. If yes, prove that there is no problem with the exhaust passage. If problems are found, the construction party is required to carry out maintenance in time. Brothers or beautiful women who are afraid of fire can light a cigarette instead.

Nine, gas (the same as natural gas)

1. Check whether the installation position and switch design of the gas pipeline are reasonable, whether the pipeline is cracked, whether the installation is firm, and whether the nose is close to smell it.

2. Check the location of the gas meter, whether the installation is firm, whether there is any damage, whether the reading is zero, and record the reading.

3. If there is an alarm device, you can test whether the alarm is sensitive. Put a smoking paper roll near the alarm device, will it sound and light to prompt the alarm, and close the air intake solenoid valve at the same time. If not, it should be repaired in time.

X. check the strong and weak circuits.

Considering the safety and cleanliness, check the strong and weak current first, and then do the waterway and related tests.

1. Check whether the distribution box is rusted or damaged and whether there is a cover. Whether the air switch of each branch is clearly marked and firmly installed, and each branch should be shaken by force to check whether the switch is sensitive. Whether the capacity of each air switch meets the requirements, and test the dynamic leakage protector. Check whether the air switch of each branch can control the indoor lamps and sockets by pulling down the switch and whether the indoor power supply is completely cut off; If there are switches in the room, you should also check whether each switch completely controls each branch line, which can be done in the following two steps.

2. Check the socket: whether there are scratches on the socket panel. In order to prevent children from putting their fingers into the socket hole, is the socket 30 cm from the ground equipped with a safety device? Whether the sockets in the kitchen and bathroom are moisture-proof sockets with splash-proof measures, and there should be no sockets above the washbasin.

Check whether the socket is electrified with an electric pen or a three-phase patch panel with an indicator light. The electric pen can be used or plugged into the reserved power socket. When the electric pen or plug-in light is on, it means there is electricity. At this point, pull down the socket switch in the main distribution box, and the electric pen or plug-in lamp will go out. When testing the socket, if the electric pen light is still on or flashing after pulling down the switch, it means that there is something wrong with the quality of the switch or the wiring is wrong, and it should be repaired immediately. This test can also use socket shaver, hair dryer and small electric fan (it can also be blown to cool down in summer, which is very practical! ) and other small household appliances, but the plug type must be able to meet the test of two-phase and three-phase sockets.

Use multimeter to measure whether the top position of the circuit socket is normal, whether the insulation to the ground is good, and whether there is a good grounding device. The zero ground voltage should be less than1v; ; If it is equal to 0, then it may be that zeros are connected together. Professionals can use special electroscope to check whether the socket is normal.

Turn the socket with a screwdriver and check whether the connector between the wire and the socket is firm and compliant.

3. Check whether the lights and switches are electrified, whether the switches are sensitive and whether the wiring is correct. The lighting seat in the bathroom must be a magnetic mouth safety lamp holder.

4. Wire inspection mainly depends on whether the wire meets the national standard quality and whether the cross-sectional area of the wire meets the requirements. Generally speaking, the wires in the home should not be less than 2.5 square meters, and the wires in the air conditioner should reach 4 square meters. Otherwise, when using the air conditioner, it is easy to overheat and soften. Bushings installed in the wall of electric wires and pipelines should be straight and firm, and the bushing connection must be tight, and the wire connection is not allowed to be twisted or knotted.

5. Check the electric meter: whether the installation is firm, whether the appearance is damaged, whether the word of the electric meter is zero, and if there is a reading, record the reading when going out after the house inspection.

6. Check the weak current entering the home: check the entry position of cable TV, telephone line, network cable and satellite TV, check whether the entry box is firmly installed, and check whether the visual intercom and emergency call buttons work normally. All kinds of limited TV lines and telephone line sockets (if any) should also be carefully understood and tested with external meters.

It is suggested that a professional electrician look at the strength of the circuit. Personal inspection can hardly find any big problems.

What must be done:

1. Look at the wall: water seepage, cracks and hollowing.

2. Check water and electricity: whether the power supply is connected will determine the quality of the conductor section.

3, waterproof test: kitchen and bathroom waterproof, block the drain, keep the water depth 2cm, the better after 24 hours, watch it upstairs and downstairs.

4. Check the pipes: especially the sewage pipes (often blocked by garbage), and whether the sewage pipes have water storage and deodorization elbows.

5. Ground inspection: height difference, hollowing and sanding.

6. Check the height of the floor: about 2.65 meters is an acceptable range. If it is less than 2.6 meters, then the house will be considered.

7. Inspection of doors and windows: tightness, height difference between inside and outside.
