Doors and Windows: Check the quality of the house in detail, including cracks in doors, windows, balconies, etc.;
1. As the new house is empty for a long time, there will be some dust and construction debris in the track of windows and doors, so you must not be very impulsive. Use brute force to pull the doors and windows. When you feel a sense of obstruction, take a closer look and use a broom. You can read it clearly
2. Are the windows in the house too tight? Is opening and closing smooth?
3. Is the door of each room open and closed smoothly? Some of the rough properties are not closed.
4. Is there a gap between the window and the concrete interface? The window frame is easy to hit, and the seam of the frame wall must be dense and there must be no gap.
Wall: flatness, water seepage, cracks
1. In particular, check if there are any traces of water on some walls, especially some gables, kitchen tops, exterior walls, etc. If any, be sure to find out the reasons as soon as possible.
2. Is there a crack in the roof? In general, the cracks parallel to the room beams are the common quality problems. Although they have quality problems, they do not impede their use. If the cracks are inclined at an angle of 45 degrees to the corners, even if they are perpendicular to the beams, it means settlement. Seriously, the house has serious structural quality problems.
Do you see any spots on the roof? This kind of pitting professional called "lime cracking point" is due to aging of lime water without sufficient time. If there are spots on the top, it will have a great adverse effect on interior decoration.
Is there any part of the wall roof uplift? Tap with a wooden stick to see if there is no sound?
3. Is there any special inclination of the wall or ceiling slab? bending? Waves? Raised or sunken place? The easiest way is to use a flashlight to illuminate the wall and the ceiling, and it can be seen at a glance.
4. There should be insulation and insulation measures for flat roofs, and roof access holes should be provided in the common parts of three floors or more.
The roof of the balcony and the houses above the three floors should be organized for drainage. The outlets, trenches, and downfalls should be installed securely, and the interfaces should be dense and not leaky.
Ground: Carefully inspect the ground for cracks in the empty shell.
1. If you have any empty drums, you must be obliged to accompany the property personnel to repair them as soon as possible. Otherwise, it will be easy to break through the floors during the renovation and hinder the relations between the neighbors. More than 2-3 available tools for gimmicks and feelers.
2. Ground
The surface layer and the base layer must be firmly bonded and not hollowed out. The overall surface is flat and does not allow defects such as cracks, peeling and sanding. Block surface layer (such as teak wood floor) should be flat, uniform and straight seams, no missing edge angle;
3. The relative elevations of the toilets, balconies, and the floor between the washroom and the adjacent ground should meet the design requirements. There should be no accumulated water, no inverted flooding and leakage, and the wooden floor should be flat and secure.
Electrical: Unimpeded and normal use
1. Install meter or reserved table according to the set (unit) and grounding device;
2. The elevator should be able to start the operation accurately, select the floor, level the floor, and stop the floor. The noise and vibration of the traction machine must not exceed the specified value. Brakes, speed limiters, alarms and other safety equipment should be sensitive and reliable;
3, using a multimeter to measure whether all strong and weak electricity flow.
4. Close the gate and check whether each gate completely controls each branch line.
5. Try to find out if there are any problems with all the switches, sockets and mains in the house? The location of various circuits, closed-circuit televisions, telephone sockets, etc. should also be carefully understood. 30% of fires are caused by electrical accidents. This is related to the setting of electrical circuits. In order to ensure the safety and convenience of using electricity, the State has issued the "Code for the Design of Housing", which stipulates that the number of residential circuits in each set should not be less than five. Increasing the loop can ensure the service life of the wire and reduce the occurrence of short-circuit fire accidents.
6. Check the sensitivity of the main power switch and leakage protection device in the room (usually based on the detection of the protector's own button to see if the protector can work);
7, socket can be powered (do not prevent charging razor and other things to test); doorbell, alarm system is working properly;
waterway
1, open the tap check leakage plug, as much as possible to make the water larger, anxious, take a look at water pressure, two, to try drainage speed. (General new houses will be equipped with a simple faucet to the owners).
How about tap water quality? Note the distinction between municipal water and residential water supply.
2. The floor slope of the kitchen, bathroom and balcony is sufficient, the floor drain is not blocked, and drainage is rapid;
3. There is no leakage during the soaking test in kitchens and toilets for 24 hours. Among them: (1) There must be no water seeping out of the wall pipe to the outside wall; (2) There should be no water from the kitchen and toilet along the foot of the wall. Seek to the hall, room wall, and foot of the wall; (3) The water in the kitchen and toilet of the upper occupants and the balcony should not seep to the corresponding ceiling of your house (especially to check the ceiling and the mouth of the vertical pipe); (4) Roofing There should be no signs of rain infiltration in the ceilings and corners and walls (especially around the windows) (checks should be done within two days after heavy rain);
Water, waterproof
1, the situation, first use the basin to hold water, and then to the various water irrigation, respectively, basin water, bathtub water, toilet water, kitchen and sanitary and balcony floor drain, basically every sink should be poured into two pots of water around You should hear the noise and the surface of the water.
2, after doing these, confirm that there is no problem, as soon as possible to these prominent water (such as basin water, bathtub water, toilet water) to take a plastic bag cover the nozzle, and then tied together, while the floor drain and other water needs to be real (Remember to leave a place that can be pulled off).
3. After all the water has been used up, the water meter should be opened again to see the number of the water meter and record it. At the same time, the number of the meter should be recorded.
4. Put water in the toilet, shallow on the line (about 2cm high). Afterwards, the owners who are downstairs are expected to check the ceiling of their home toilet after 24 hours.
5, there is no water stains on the roof? crack? If there is a water stain, it is suspected that there is a leak. If you are a resident of a top-floor house, then you must not forget whether the top floor is leaking.
In the end, check the work. If there is no problem, then pay the money. If there is a problem, you need to determine the solution and the date of settlement with the property person to see if the result of the settlement will affect the settlement. If they are affected, they need to negotiate. Now.
