First, the most important air testing
With the renewal of concepts, environmental protection has become the most important link for consumers in home decoration, and air pollution is the most prominent problem in decoration pollution, and it is the main cause of many kinds of physical and mental diseases. Since the materials used in the fine decoration rooms are purchased by the developers, the owners cannot control the quality of the materials. Therefore, the first thing the owner must do to confirm the quality of the air is when the property is delivered.
First of all, the owner must ensure that the materials purchased by the developer meet the national standards and the hazardous substances do not exceed the standards. Second, according to the national standards, after the completion of the project, the developer must ask the authoritative organization to carry out indoor environmental testing and must issue a test report to the buyers. The current air quality inspection standard is GB50325-2001, which strictly regulates the five major harmful substances in the air: formaldehyde, benzene, TVOC, helium and ammonia. Experts cautioned that it is important to note that only reports with the “CMA†logo are reports approved by the state that are tested by the most authoritative testing organizations. Otherwise, they are invalid.
If a consumer buys a house, if the developer or property cannot provide a qualified report, it is deemed that the quality of the house is not qualified. From the perspective of rights protection, the owner can check out.
Second, the hidden project should be meticulous
Covert projects include waterway reconstruction, circuit reconstruction, ceiling structure and bathroom waterproofing projects. The owner did not understand the materials used in the concealment project, the piping of the waterway, the direction of the circuit, and the location of the functional outlets, etc., because these projects were buried in the wall after the handover. However, the owner must understand at least the following situations. In view of the relatively high requirements of the hidden project for the profession, if the consumers do not understand it well, it is recommended that friends or professionals who understand the relevant knowledge be escorted.
Third, the waterway
Ordinary real estate waterways are usually three kinds, tap water, hot water and medium water. Reclaimed water is non-potable water, which is used for collecting and utilizing rainwater. It is generally used to flush toilets or watering flowers. Consumers need to know if hot and medium water are available and whether they are taking the wrong pipe. Also check the position of the water meter, which should be at the water outlet of the kitchen or bathroom. In addition, the material of the water pipe is directly related to life and must be determined as a qualified material designated by the country. If the water pipe material is too bad, it is easy to leak water later. The best water pipe material is copper pipe, but at present, there are not many projects using copper pipe in Beijing; PPR pipes imported from Germany are also good.
Fourth, the circuit
Circuits refer to the location and matching of outlets, the type of Wire and the capacity of the largest consumer. This requires consumers to ask the property management company or developer in their community for the basic drawings of water, electricity and other concealed works. In the future use, if there is a short circuit or water cut, it can be repaired by a professional according to the drawings. In addition, we must also pay attention to whether the leakage protection switch of the distribution box has lighting; whether the ordinary socket, high-power socket, etc. have a clear shunt, whether the installation of the panel switch is smooth, and whether the switch is valid.
Fifth, ceiling
The structure of the suspended ceiling is not shown on the as-built drawings, but the structure can be seen on the side of the hardcover room, the lamp position, or the ventilation of the central air conditioner. The ordinary owners can judge from the ceiling of the ceiling visually, and according to the relevant regulations, the light steel keel must be used for the concealed ceiling. The previously used wooden keels themselves contain water, which may have contraction changes in the four seasons, especially after heating in winter, and have been eliminated. The performance of the light steel keel is very stable and the service life is relatively long.
Sixth, waterproof
Pour clear water in the bathroom to test whether the water is open. If the lowest point of the floor drain cannot have accumulated water, the water should be open at all places.
Details reflect quality
In addition to the above aspects of the impact of living, some of the details of the problem can also reflect the level of construction of fine decoration. The owner can inspect the quality of the decoration of the house from these places.
Seven, wall paint
Wall should be used water-resistant putty, wall paint brushing should be uniform, uniform film.
Tiles: the same color. Visual inspection can, generally speaking, if there are obvious problems, developers will not pass the inspection. Tap the floor tiles and wall tiles with a small hammer. If there is a hollow sound, it means that the tiles have not been laid. It may take a long time for tiles to crack and fall off. Emptying rate of more than 5% can be judged as unqualified.
Eight, kitchen and bath
Test whether the faucet switch is flexible and effective, including flush toilet, shower room, and wash basin. In addition, it is necessary to check whether the water is unobstructed. You can fill the vegetable sink, basin, and bathtub with water at the site and then discharge it to check the drainage speed. When you check the toilet water, you must repeat the drainage test several times. Drainage effect.
Nine, doors and windows
Push the door open by hand to check whether the room door switch is smooth, whether the door lock hinge is flexible and effective, and whether the doors and windows of the closed doors and windows of the closed balcony are qualified and whether the opening is flexible.
Ten, heating
Consumers can check the heating, see if the lines are unblocked, if the temperature is up to standard, and if there is a leak.
Ventilation: Test whether the ventilation outlet is ventilated smoothly, and whether the return valve is valid in the kitchen and bathroom. If your kitchen always has the smell of someone else's home or the bathroom has a bad smell, it may be that the return valve has failed.
Eleven, verify the building materials model
The main materials used in the fine-tuned housing project should be clearly stated in the contract, especially the equipment with high gold content, such as sanitary ware, lamps, kitchen equipment, furniture hardware, sanitary ware hardware, as well as anti-theft, fire protection and sound insulation. Functional multi-function doors; in addition to the brand, but also need to specify the type of equipment, and some of the equipment related to the origin should also clearly identify the origin.
When the homeowner checks the house, it must be compared with the configuration of a single, to avoid being transferred by inferior products, and to reduce the grade of decoration. Experts said that because many engineering problems are related to the quality of building materials, if this is a good point, then many follow-up problems can be avoided. Therefore, the owners are advised to pay more attention.
XII. Observe during the warranty period
Due to the quality of some projects once completed, or many projects need to be observed for a long time, it may not be able to check whether it has quality problems when it is completed and accepted, and it must be discovered through use. At present, the warranty period for residential decoration prescribed by the state is two years, and the warranty period for kitchen and toilet waterproofing works is five years. The industry focuses on carefully observing the various quality problems that occur in the houses, negotiating with developers or properties in time, and trying to resolve them within the warranty period.
