Second-hand housing renovation demolition renovation costs, old housing renovation environmental protection priority.

The decoration of second-hand houses is more particular than that of new houses, because second-hand houses are built on the basis of old houses. Living in an old house for a long time will inevitably lead to many security risks. It is inevitable to dismantle and transform them. Bian Xiao, the home improvement network below, introduces the related knowledge of second-hand housing decoration for everyone. Let's have a look.

First, the second-hand housing renovation and demolition costs

1. The demolition expenses mainly include the demolition of walls and floor tiles, the original walls, top foundation and putty, doors and windows, old furniture, wallpaper and the original ceiling. Quotation depends on labor and management costs, and each company is slightly different.

2. After the original sand ash base of the old wall surface is cleared, it is necessary to level the cement mortar at the top base of the wall again. The general cost is 20-30 yuan per square meter, and "removing the original wall putty" is 4- 10 yuan per square meter.

3. The original walls of old houses are mostly uneven, so the cost of "finding the angle of yin and yang" is generally per meter 10- 15 yuan, and the cost of "finding the door and window" is per meter in 20 yuan and 30 yuan.

4. Generally, the garbage clearing fee is the clearing area per square meter 10 yuan. If the property is not shipped abroad, each car needs extra freight, 200 yuan.

5. If it is a partial renovation of an old house, it is necessary to add a finished product protection fee of 20 yuan per square meter (the following two cases involve the finished product protection fee: if it is a partial renovation of a house, some decoration companies will do professional finished product protection; If the house is completely renovated, but the owner still has some big items to store in the construction site, such as household appliances, furniture and other items, which need to be repeatedly handled during the renovation process).

6. The cost of water and electricity is more than the renovation of new houses, depending on the quotations of water and circuits of various companies.

Second, environmental protection of materials is a priority.

1. The original wall surface and top surface base are lime-sand walls (hemp knife ash), which need to be removed and the cement plastering base should be redone.

Due to aging, the circuit of the old house needs to be replaced. Because modern household appliances are widely used, the replaced wires need to meet the national standards, and galvanized iron pipes need to be set during construction. When laying wires, shunt arrangement should be made according to the new design scheme (generally divided into lighting, low-level socket, high-level socket and weak current).

3. The original decoration of old houses generally uses hydrophilic gypsum putty, which needs to be completely eradicated before it can be replaced with water-resistant putty.

4. With the consent of the property, external doors and windows can be replaced. Nowadays, plastic steel windows and aluminum alloy windows are generally used.

5. galvanized iron pipes and aluminum-plastic pipes are widely used in the waterways of old houses, which can no longer meet the needs of modern life. Waterway galvanized iron pipe is easy to corrode and harmful to human health, which has been banned by the state. Aluminum-plastic pipes are easy to fall off, and water seepage causes hidden dangers in later use. Therefore, PPR pipes are often used now, and experiments need to be suppressed after the construction of new pipes is completed.
