Who is to blame for the cold and long hair in the house?

If the house is under warranty, the developer is responsible for maintenance; Upon expiration of the warranty period, the owners' committee shall make a decision to start the maintenance fund. It is usually difficult to start the maintenance fund. If the wall leakage is serious, you can ask the relevant departments to identify and activate the maintenance fund through emergency procedures.

According to the Measures for Quality Warranty of Housing Construction Projects, if there are quality defects in housing construction projects within the warranty scope and warranty period, the construction unit shall fulfill the warranty obligations.

The construction unit and the construction unit shall stipulate the warranty scope, warranty period and warranty responsibility in the project quality warranty.

Under normal use conditions, the minimum warranty period for roofing waterproof works, toilets, rooms and external walls with waterproof requirements is 5 years.

In other words, if the house has been purchased for less than 5 years, the developer can be held accountable for the moldy wall;

If the new house has passed the five-year warranty period, the property should be responsible for the waterproof project of the house quality.

However, quality defects caused by improper use or third party reasons or quality defects caused by force majeure are excluded.

Cool through the heart is a common name, but it is actually the reason why the wall insulation is not done well. Do you think the wool wall is an external wall or a wall related to the outside world? If so, that's basically the reason.

The wall insulation is not done well, which belongs to the building quality problem. In the north, an important part of building construction is external wall insulation. In the north, thermal insulation measures are generally taken, and the main method is to sandwich thermal insulation materials in the wall. Hinder the heat conduction of the wall.

If the wall insulation is not done well, it will lead to cold infiltration. The cold phenomenon is that the indoor walls are moldy, black and hairy. The reason is that the indoor air is warm, the water vapor saturation is high, and the wall is not well insulated, so the wall is cold and the water vapor will crystallize into water droplets on the wall. When the wall is wet, it will be moldy and hairy.
