Step 1
Look at the appearance of the villa first, and pay attention to the observation: whether the external wall is cracked and whether the surrounding foundation is sinking.
Second step
Try the intercom security system at the entrance of the villa. Pay attention to whether the system is consistent with the brand and model agreed in the contract.
Third step
After entering the house, from the entrance door, the floor and wall of the living room space such as hall, living room and bedroom are detected in turn for hollowing and cracking, and the scraped wall is wrinkled. Use small hammer, angle of yin and yang, measuring ruler and other related tools.
Fourth step
Check whether the doors and windows are scratched, especially pay attention to whether the doors and windows are tightly sealed, whether they are installed in place, whether they are inclined, and whether the floor-to-ceiling windows with large glass areas are equipped with protective fences.
Step five
Enter the bathroom, kitchen and other spaces and observe with the naked eye whether there are traces of water on the ground, walls and other corners. Then drain water, do waterproof test, and observe whether there is water seepage after 24-48 hours.
Step 6
Observe whether the pipes of water supply and drainage system in toilet, kitchen and other spaces are unblocked. Try to fill toilets and various floor drains with water, and pay attention to whether there is running water. If it is silent, it may indicate that a part of the pipeline is blocked. If the drinking water is the groundwater of the self-provided well in the community, it is necessary to pay attention to whether its water quality meets the standard.
Step 7
Check whether the gas meter, water meter and electric meter meet the standards. Ask the developer if it is necessary to go to the bank to collect fees. If charging in the community may be temporary, you should agree with the developer in advance on the date of receiving municipal electricity.
Step 8
Check whether the villa heating system is qualified. Most villas are heated by households, and observe whether the brand of wall-hung boiler is consistent with the contract; If it is municipal or residential central heating, check whether the radiator matches the living room area. In addition, you can try to suppress the heating pipe. General wall-hung boiler pressure 1.5 is 2, and central heating pressure is 6-7.
Step 9
Check whether the circuit installation is qualified. Measure the minimum cross section of the wick leading to lamps and sockets. Generally, the cross section diameter of household batteries is 2.5 mm, which is acceptable. In addition, pay attention to whether the leakage protection system is sensitive.
Step 10
A villa usually has a basement and a terrace. Enter the basement or board the terrace, observe whether there are traces of water in these parts, and do waterproof tests if necessary.

Four measures for detecting water leakage
1 trick: the waterproof layer of villa basement is generally 30-50 cm higher than the ground. It is necessary to observe whether the actual height of the waterproof layer of the basement exterior wall is up to standard.
The second trick: the basement with windows should observe whether the windows are tightly sealed and whether there are traces of water infiltrating into the room.
The third measure: check whether the balcony and ceiling lamp are leaking. The simple way is to go indoors and see if there are any signs of water seepage inside. In addition, observe whether the slope of the roof eaves reaches the standard, whether the downpipe is tightly sealed and whether there are signs of water seepage. Waterproof test can be done on the terrace if necessary.
The fourth measure: for bathrooms, kitchens and other spaces, you can observe with the naked eye whether there are traces of water. Do a waterproof test if necessary.
