Introduction to house collection and inspection
Door and window inspection:
In addition to shaking, you have to use a magnet to check whether there is a steel lining inside.
In the raiders, from the moment you enter the door, you start the viewing mode. However, almost all strategies only focus on checking the integrity of doors and windows. For example, shake the doors and windows to see if they are firm, check whether they are damaged or deformed, and how tight they are.
In fact, there is another important inspection strategy that won't tell you, that is, check whether the doors and windows have steel linings. It is understood that generally adding steel linings at the four corners of doors and windows can strengthen doors and windows, prevent them from falling off, improve quality and ensure safety. Professional home inspector usually has a pen to check the steel lining. But Li Lin gave a trick, "you can use a magnet instead. Now doors and windows are generally made of aluminum alloy. It is very useful to find out whether there is a steel lining when attracting magnets. "
Empty drum problem:
It's hard to tell the difference between listening and knocking, so it's best to find a professional.
As the biggest headache for owners and decoration companies, the problem of empty drum is also the top priority in house inspection.
In the strategy of checking empty drum uploaded on the internet, it is generally recommended to use a small metal rod or a very small empty drum hammer to distinguish it by the sound made by knocking. However, in Li Lin's view, this is the most difficult one for car owners to check themselves. "In particular, the joint between the beam and the wall, which is most prone to empty drums, will sound like empty drums if it is filled, but it is not empty. A professional home inspector must be trained in hundreds of houses before it can be correctly distinguished. " This is too difficult for ordinary owners.
It is best to invite experienced friends, or find a good decoration company in advance, and the personnel of the decoration company will check it on their behalf.
Height detection:
The tape measure is not accurate, and the infrared instrument is accurate.
It is necessary to measure the height of a house when checking it. In order to ensure the horizontal and vertical, most owners measure the four corners of the house with a tape measure. But a truly experienced home inspector wouldn't do that. Because the four corners are generally higher than other places, the height of the floor should be measured 50cm away from the corner. But when the angle is outside 50cm, it is easy to produce errors.
Therefore, in order to achieve accuracy, a special infrared measuring instrument is needed. However, the lowest-priced infrared instruments are all above 300 yuan. In order to save costs, the owner of the house suggested that it can be purchased and used with other neighbors.
Geometric dimension check:
It is invisible to the naked eye. Use an infrared measuring instrument.
Geometric size is the most easily overlooked by the owner when inspecting the house. If there is an error in the geometric dimensions of the room and the doorway, it can't be distinguished by the naked eye. At this time, infrared instruments are needed.
"Simply put, there is an error in the geometric size of the room, which will make the two walls that should have been parallel become non-parallel. This will cause unsightly decoration and disharmony. " If it is not found before the house is closed, the owner needs to make compensation by scraping putty. Generally, the cost of a wall needs to go from 300 yuan to 500 yuan.
In addition, the geometric size of the door opening also needs to be checked. It is understood that the width of the entrance door, bedroom and bathroom should be above 880cm, 800cm and 700cm respectively, and the height should be 2.3 meters. There shouldn't be problems like size.
Water and electricity waterproof inspection:
Confirm the number of wire groups and measure the waterproof height.
The description of hydropower inspection in most raiders is feasible, but it is worth noting that in Chongqing, there are several points that need special attention.
First, when checking the weak box, it is necessary to confirm whether there is a closed circuit, network, telephone line, etc. Some developers in Chongqing will use network cables instead of telephone lines, so there will be a lack of telephone lines at home, which will make it inconvenient to use later.
In addition, waterproof also deserves special attention. Generally speaking, the waterproof height of the toilet should be 1.8 meters. But this 1.8 meter should be calculated from the horizon, not from the settlement as some developers do. If calculated from the settlement, it should be 2.3 meters. At the same time, it is necessary to check whether the sewage pipe is unblocked. Don't use the method of pouring small pots through the net, but fill them with large pots at one time, otherwise it may cause backflow due to local blockage.
What are the strategies for closing the house and inspecting the house? The owner has a lot of work to do and needs to prepare some tools for the house inspection. Never go to the house empty-handed, thinking that you can check out the quality problems in the house with your own naked eyes or experience. I really don't know how to collect and inspect houses. I suggest you find an experienced person when decorating, or entrust a decoration company to ensure that your new house will not have any quality problems, and you will be more at ease in the future.
