It is also beneficial for consumers to master some professional and technical problems when buying a house. The following are some common housing quality problems.

1. This building is unstable. Explain that it is still sinking after the settlement period; Uneven settlement causes buildings to tilt; The overall strength is not enough, and the building shakes after shaking or in strong wind; Due to the imperfect structure, some or all of the load-bearing systems are under-loaded, which leads to the hidden danger of partial or total collapse of the building.

2. cracks. Include wall cracks and floor cracks. Cracks are divided into strength cracks, settlement cracks, temperature cracks and deformation cracks, which are caused by insufficient material strength, uneven stress on structures and walls, insufficient tensile and collapse strength, uneven settlement of buildings, inferior building materials and insufficient drying after masonry.

3. Leak. Due to the imperfect waterproof technology and poor quality of waterproof materials, roof leakage, horizontal leakage in kitchen and bathroom, vertical leakage downstairs, vertical leakage is more common in the joints of various pipes and floors. In the rainy season and when the water consumption of kitchen and bathroom is large, serious leakage will affect the normal life of users, destroy the ground decoration and affect the neighborhood relationship upstairs and downstairs.

4. The wall is empty and the wall skin falls off. The poor connection between the building blocks in the wall and the interlayer leads to cavities under the action of pressure and temperature difference, which reduces the overall compressive capacity of the wall and makes the surface paint layer easy to fall off. Sometimes, under the condition of not hollowing out, the quality of wall painting materials is poor and the painting process is not in place, which will lead to a large area of wall skin falling off.

5. The sound insulation effect is poor. The partition walls and floors in residential buildings have poor sound insulation and shock absorption effects, which can not meet the requirements of privacy; The roof and external wall cool down quickly in winter and heat up quickly in summer, which can't meet the requirements of thermal insulation. The reason for the above phenomenon is that the thickness of sound insulation materials for walls and roofs is not enough, the quality of materials is poor, or the construction technology does not meet the requirements.

6. Doors and windows are poorly sealed and deformed. Some doors and windows were installed later, and some problems such as poor sealing, local materials or overall deformation occurred after a period of use. In severe cases, it is impossible to block the line of sight and shelter from the wind and rain, and some cannot be closed and opened. The reasons for the above problems are that the quality of the selected materials is not good, the wood is not dry enough, or it is attacked by moisture after installation and the workmanship is rough. Generally, the quality problems of doors and windows are not harmful, and only local maintenance or replacement is needed.

7. Run up and down. Leakage wastes resources and affects people's normal life. The reason is that the horizontal and vertical design of water supply and drainage pipeline is not reasonable enough, and the quality of faucet and toilet is not up to standard.

8. The design positions of water, electricity, heating and gas are unreasonable. Including pool, bathtub, squatting (sitting) toilet, water meter, floor drain, power switch, power socket, electric meter, radiator, gas stove, gas meter and other design types are not perfect, and the design position does not meet the requirements of daily life, which affects the furniture layout. Some electrical equipment even has leakage and fire hazards.

9. The design of public facilities is unreasonable and the quality is not up to standard. For example, the stairs are inconvenient, the width of the stairs is too small, the running quality of the elevator is unstable, the public lighting facilities are not perfect, and the fire safety facilities are lacking.

Case 1: Check out!

In September this year, Miss Liu finally decorated the newly bought house. In the first week after moving in, she found that the noise of the substation on the 1 floor of the building kept the whole family awake at night. Miss Liu felt that noise seriously affected her living and physical and mental health, and communicated with developers, property and consumers' associations successively. Although mediation failed. So she entrusted the district environmental monitoring station for testing, and the result was that the noise had indeed exceeded the standard. He sued for the cancellation of the housing sales contract signed with the developer, and the developer returned the purchase price and compensated for the loss of interest. The court held that developers have the obligation to ensure that the houses they deliver meet the residential purposes and can be used by others for normal living. Now because there is a substation in the building, the noise of the house exceeds the standard, which is difficult to improve and does not meet the living conditions. So I support Miss Liu to check out.

Case 2: Indemnity!

Mr. Wang had a mind when the developer handed over the house, and invited friends from the house quality inspection station to inspect the house together. When inspecting the house, it was found that the house was of brick-concrete structure, but the original agreement was that "the commercial house sold was of steel-concrete structure". Mr. Wang found that the house had changed from the agreed steel-concrete structure to the brick-concrete structure, and felt that he had spent money unjustly and demanded compensation from the developer. The court held that if the main structure of the house changes, Mr. Wang Can can ask the developer to give economic compensation or choose to return a house.

What quality problems can be checked out for compensation?

1. If the owner is verified by the engineering quality supervision unit that the quality of the main structure is indeed unqualified, the buyer has the right to reject the house, terminate the commercial house sales contract and demand the developer to compensate for the losses.

2. The main quality of the house purchased by the owner is qualified, but other quality problems of the house seriously affect the normal living and use. The developer shall bear the liability for breach of contract, and the buyer may request to terminate the contract and compensate for the losses. "Seriously affecting the normal use of the house" generally refers to the situation that the house purchased by the buyer has serious quality problems, and the quality problems can not guarantee the personal and property safety of the buyer and the normal use of the house after being repaired.

3. If the house purchased by the owner has quality problems, it has not yet reached the severity of "seriously affecting normal living and use". In this case, the developer slightly breached the contract, which did not reach the level of fundamental breach of contract, and the owner could not ask to cancel the contract and return the house. Only the developer can be required to bear the maintenance responsibility during the warranty period. If the developer refuses or delays the maintenance within a reasonable period of time, the owner can maintain it by himself or entrust others to maintain it, and the maintenance expenses and other losses caused during the maintenance period shall be borne by the developer.

After the quality problem occurs, the owner should make a preliminary analysis of the degree of quality defects and whether the main quality of the house is unqualified or seriously affects the normal living, so as to take corresponding countermeasures. In the above two cases of housing quality disputes, the buyers are on the right track, and their rights protection is relatively smooth. However, if the right method is not adopted, it is difficult for buyers to safeguard their rights and interests even if they are wronged.

Case 3: Improper rights protection is not worth the loss.

When Mr. Zhang accepted the house, he found that there were obvious cracks in the floor and ceiling of the living room and master bedroom (the crack length exceeded 1. 5 meters), vertical, oblique and horizontal cracks were found in many parts of the wall. Through mutual understanding with other owners, there are similar phenomena. Mr. Zhang wrote to the general manager of the developer twice, explaining that there were obvious cracks in the house and asked for rectification. Moreover, Mr. Zhang refused to accept the house and refused to pay the balance of the house payment. Afterwards, both parties appealed to the court. The court held that the house delivered by the developer was indeed flawed, but Mr. Zhang refused to accept the house on this ground, which lacked legal basis. Therefore, the judgment did not support Mr. Zhang's claim, and Mr. Zhang should also pay liquidated damages for overdue payment of the house price.

Case 4: lose your temper and find the wrong person.

Mr. Li's new house has only been in for half a year, but as long as it rains heavily, the two bathrooms, kitchen, two bedrooms and study will leak. The property has been repaired many times and has never been repaired. The property company said that this is the quality problem of the house itself and should be solved by the developer. Mr. Li believes that the property company and the developer are in a father-son relationship, and the property company should bear the responsibility. He refused to pay the property management fee for nearly two years. The property company sued the court, and the court held that the property company had fulfilled its maintenance obligation and sentenced Mr. Li to pay the property management fee.

Case 5: The court found that the developer had repaired it.

The house purchased by Mr. Zhang should have been delivered in February of last year, 65438, but it has not been moved in until now. According to his own measurement, the net height of the bedroom in the house delivered by the developer is only 2. 16 meters, the clear height of the kitchen is only 2. 15m. The Code for Residential Design jointly issued by the State Bureau of Quality and Technical Supervision and the Ministry of Construction has long expressly stipulated that the indoor clear height of bedrooms and living rooms (halls) should not be less than 2. 40m, local clear height should not be less than 2. 10 meter. The indoor clear height of kitchen and toilet should not be less than 2. 20 meters. After the developer received his complaint, he immediately lowered the ground and increased the clear height inside the house. Finally, the contradictions between the two sides could not be reconciled, and the lawsuit hit the court. The court held that the height of the building is not the main structural problem of the building, and the developer has carried out repairs, so he refused to return the house.

Case 6: This judgment is really helpless.

Miss Zhao found that the imported Toshiba elevator was installed in the commercial housing sales contract, but now it has become a domestic elevator. That is, the developer was asked to replace the elevator, but failed, and Miss Zhao sued the court. The court held that Miss Zhao often ignored the performance cost when advocating public facilities performance. If the supporting measures for the company do not meet the quality agreement, it needs to be remedied. If the performance cost is too high, one party will bear unreasonable obligations. Therefore, Miss Zhao's request was rejected.

Lawyer's summary:

There are many kinds of housing quality problems, such as damage to the main structure, cracks in the wall, insufficient height, tilt of the house, damage to doors and windows, water leakage of the house, noise of the house, and inconsistency of housing equipment with the contract. This kind of quality problem may be found before repossession or after occupancy. In order to avoid quality problems, consumers are advised to choose a developer with good credit when buying a house, to fully understand the quality of the real estate built by the developer and the qualifications of the contractor, and to control the risk in the early stage.

Before moving in, you should issue a construction quality certificate to the developer, make sure that the house has passed the acceptance and is consistent with the purchase contract, and then sign the check-in form.

If there are housing quality problems after occupancy, the owners should first take a proactive attitude and negotiate with the developers to solve them. If negotiation fails, the owner may complain to the Consumers Association, the Construction Committee and other departments or bring a lawsuit directly to the court. Most importantly, consumers must pay attention to retaining evidence after discovering housing quality problems.

First of all, you must keep the original contract, bill of materials, payment invoices and other written documents, such as taking relevant photos and recording the severity of quality problems in writing. Please get the consent of the property management company, neighbors or neighborhood committees as far as possible for the losses caused.

Secondly, it is necessary to send a written notice to the developer in the form of registered mail, asking the developer to come to repair and inform him of the loss. Every repair, including repair time, measures taken by specific personnel and repair effect, should be recorded in writing and signed by relevant personnel. Finally, you can claim compensation from the developer according to the facts, such as the compensation agreement in the purchase contract.

After the delivery of the house, the owner thinks that the quality of the main structure of the house is unqualified, and may entrust the engineering quality inspection agency to re-verify. If it is found unqualified, the owner has the right to return a house and ask the developer to compensate the relevant losses according to law.

Chen Fang. Com specially reminds that most of the current commercial houses are faster, and buyers can't check the construction quality in advance. Therefore, in order to avoid quality problems, consumers are advised to choose a developer with good credit when buying a house, and fully understand the quality of the real estate built by the developer and the qualifications of the contractor, so as to control the risk in the early stage.
