In home decoration, many materials used in some second-hand houses have been upgraded to environmentally friendly materials. In the following situations, it is best to replace it.
The original wall surface and top surface base are sand-lime walls, which need to be removed and re-made with cement plastering base.
Second-hand housing circuit aging needs to be replaced. Because modern household appliances are widely used, the replaced wires need to meet the national standards, so galvanized iron pipes need to be set up during construction.
When wiring, it should be arranged according to the new design scheme, which is generally divided into lighting, low-level socket, high-level socket and weak current.
Two: the surface thickness of the floor is required.
Floor renovation is to restore the old floor as new by polishing, scraping putty, painting and waxing the floor surface.
Compared with repaving the floor, the old floor adapts to the indoor environment, with better stability and much cheaper decoration cost.
Three: random demolition and modification of the structure leads to the collapse of the wall.
The apartment structure of second-hand houses is often not very good, so some netizens are already planning to modify the structure of houses, where to add a porch, open a wall and so on when they are in second-hand houses. Because the multi-storey residential buildings in cities are mostly brick-concrete structures, the walls are first load-bearing seismic components, and then the enclosure partition components.
Four: the bathroom leaks and causes trouble.
Don't think that the second-hand house has been occupied by the previous owners, and there will be no problem with waterproofing. In fact, people often complain about the leakage of lower-level owners after moving into second-hand houses.
Because the house is too old or the original waterproof is not done well, many second-hand houses have water leakage in the bathroom space.
It is suggested that before moving into a second-hand house, it is best to do a closed water test in the bathroom space to check how the waterproof treatment was done before.
Five: the waterway gas pipeline is seriously aging.
Because the materials used in second-hand houses are not advanced now, and the age of the houses is relatively long, many second-hand houses have the problem of aging water circuits. If you don't check carefully in advance, you may not live long, the lights don't work, and the water pipe bursts again.
