Steps/methods

First, the new house inspection room matters needing attention

1. 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.

2. Are the windows in the house too tight? Is opening and closing smooth?

3. 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.

4. Is there any spot 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.

5. Are there any uplifts in the ceiling of the wall? Tap with a wooden stick to see if there is no sound?

6. Is the toilet water flowing? Is flush sound normal? Does the flushing water tank leak sound?

7. Whether there is a floor drain in the bathroom or kitchen, if the slope is right, it must not be tilted toward the entrance, otherwise the water will flow into the living room.

8. What are the problems with all 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.

9, 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.

10, the material of the water supply pipe? At present, most of the water supply pipes use copper pipes. Brass can be used safely for 50 years. Copper can inhibit the growth of bacteria and increase the copper content in water, which is beneficial to health.

11. Is it proper to test the gas water heater switch?

12. Are all the indoor and living room pipelines exposed? Is there a pipeline through? Because there are more pipelines crossing the home, it will cause difficulties in decoration, and it will also cause visual obstacles and affect the overall sense.

13. How about the quality of tap water? Note the distinction between municipal water and residential water supply.

14. Are there any special inclinations for the wall or ceiling slabs? 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.

15. Check if the house is clean? Is there any residual construction waste? See if there is rubbish in all dismantlable spaces?

16. The developer is requested to issue the completion record table of the property and the surveyed area detailed list of the surveying and mapping units. Fourth, to retake what to check? Area, electrical, roof, floor, decoration, structure, exterior wall can not be less to buy an area from the practice of housing transfer point of view, due to the calculation of commercial housing sales area is not well understood, most buyers only pay attention to the housing structure, decoration Acceptance of quality, while neglecting the verification of the area of ​​the house. In fact, the size of the housing area not only affects the ultimate property rights, but also involves housing prices, which has a direct impact on the economic interests of buyers. Therefore, verifying the sales area of ​​the purchased houses is also an important link in the acceptance of houses, and should cause buyers to pay great attention. The calculation of the area of ​​purchase should be based on the “Agreement on Sale Area of ​​Commercial Housing and Allocation of Public Building Area (Trial)” promulgated and implemented by the Ministry of Construction.

Second, new home inspection room 14 strokes

1 trick: look at the "record" to stay "two books" before the new home occupancy, the owner should see a copy of the project's relevant filing documents in order to confirm that the project is a legal construction; at the same time, should be provided by the developer of the "residential quality warranty And Residence Instructions.

2 strokes: The bathroom does not leak. Check whether the floor of the bathroom is leaking. You can use plastic bags filled with sand to place on the floor drain, and then store some water in the bathroom. After 24 hours, go to the corresponding lower bathroom to see if there is any leakage at the top. This test is best performed at the same time as the upper occupants, so that it can detect whether there is leakage on the floor of their own bathroom or whether there is leakage on the top of their own bathroom. Check whether there is water on the bathroom floor, but also store some water in the bathroom first, and then release water to see if there is water accumulation on the ground. There should be no stagnant water on the qualified ground, because the floor drain is the lowest point of the toilet. However, except for the rough house, there is a certain height of the post-drainage ground around the floor drain.

3 strokes: Tap each side to hear cracks. Whether there is cracking in the plastering of the wall, the floor decoration surface layer and other decorative surface layers, just use a small hammer to gently knock. If you hear the voice of “empty”, it means that each surface layer is in contact with the wall (ground) surface and needs to be reworked; if you hear a dull knock, it means that they are in good contact.

4 strokes: Top residents check for rain. If you are buying the top floor, be sure to check the top surface of each house for signs of rain leakage. Because according to the construction requirements, the houses handed over have either passed the “test” of two heavy rains, or the construction party has conducted rain tests under the supervision of the supervision unit.

5 strokes: the risk of cracks in the balcony. In general, the cracks in the wall are mostly not structural cracks, affecting the appearance, but the danger is not great. Problems with the structure of the house often appear on the balcony. If there is a crack in the connection between the room and the balcony, it is likely to be a sign of the breakage of the balcony. The relevant unit must be notified immediately.

6 strokes: Insulation is not good wall dripping. In winter, if there is condensation in the walls of the room (similar to the summer iced bottle beer and water droplets appearing on the outside wall at room temperature), there must be a problem with the wall insulation.

7 strokes: open the leader check leakage plug. The upper and lower water pipes have no seepage, leakage, or blockage. Open the water tap and notice that, as far as possible, let the water flow be a little bigger and anxious. Let's take a look at the water pressure and try the drainage speed.

8 strokes: The heating branch has a slope. The heating supply and return branch pipes are not horizontally arranged. The water supply branch pipe is connected to the water pipe at the end higher than the end that connects the radiator. The water return branch pipe has the opposite height at both ends. This slope is proportional to the length of the two branch pipes. Generally 1% difference per meter.

9 strokes: The heating pipe should be sleeved. The heating pipeline shall be provided with a casing through the wall and through the floor (in the intersection of the pipeline and the wall or floor, a small pipe shall be put on the pipeline). The casing on the ground shall be 2-3 cm above the ground, and the ground shall be The decoration should be 5 cm above the ground. Its role is to prevent the heating pipes from swelling and shrunk and then arching the walls and floors.

10 strokes: Power cuts are indispensable. When the gate and meter are outdoors, they should check whether they can control the indoor lamps and the indoor outlets. After the gate is turned on, whether the indoor power is completely turned off; if the gate is open, the gates should also be checked separately. Control each branch line.

11 strokes: insurance outlet care for young children. In order to prevent young children from putting their fingers into the socket, the socket must be equipped with a safety device that is located at a height of 30 cm from the ground.

12 strokes: more rules for bathroom sockets. The power outlet in the bathroom shall be a moisture-proof outlet with splash-proof measures. The lighting base of the toilet shall be a magnetic port. There shall be no socket above the wash basin.

13 strokes: Kitchen close to ventilation. The kitchen and toilet should be arranged near the air passages, which will facilitate the rapid discharge of odors, exhaust gases, etc., and keep the indoor air clean.

14 tricks: pull the switch interface pull. Check the firmness of the switches and sockets. Don't forget to open the line interface of the phone and TV. Pull it hard and see if it is a virtual one.
