With the marginalization of lots of new houses, many people choose to purchase second-hand houses with relatively mature community conditions in urban areas. With the rise of second-hand houses, the renovation of second-hand houses has also become a hot spot in the home improvement market, but the structure of old houses and new houses are very different. The big difference is that if you don't know enough about the house, you are starting to hurry up the renovation, not only hurting the house, but also hurting you. Therefore, be sure to be aware of the room structure before starting to reconstruct the second-hand house.

Now. One inattentive, hurt the house hurt you.

Many owners report that there are always construction errors during the demolition process, adding many annoyances. Here, Xiao Bian collected the cases that the owners reflected most frequently in the renovation of second-hand housing, and it was the most problematic case. It was found that the renovation of home-built bearing walls and concealed works was still a major difficulty in the modification of second-hand houses. Therefore, Xiao Bian consulted Professional supervision and decoration company, to bring us a detailed solution to the problem of second-hand housing modification, so that second-hand housing conversion, no one will hurt.
Case I: Destruction of bearing walls
Danger factor: ★★★★★
Many netizens reported that due to the unreasonable design of some old houses, they would think of demolishing the walls during the second renovation. However, most netizens have little knowledge of the type of room. A random knock on the wall not only has a high cost for dismantling the wall, but also causes a great harm to the house.
Expert retrofit suggestions: Due to the small size of the old apartment layout and the compactness of the space, there are certain limitations in the decoration design. To avoid damaging the bearing wall, you may try to use the late home accessories to achieve the effect of space expansion. For example, if you think there is a lot of walls, , you may wish to make it into an artistic photo wall.
Case II: The waterway reform is not standardized
Risk factor: ★★★☆☆
Another major renovation project was the removal of outdated ceilings, floor tiles, putty layers, paint layers, and waterproof layers. If the kitchen and the bathroom are changed, the water and electricity must be moved. Slotting the tiles and removing the pipes will result in great waste if the treatment is not done properly, and it will cause safety problems for future use. In addition, the oxidation of water can cause local rust and pollution in the old residential pipelines. In particular, the location of pipe fittings is rusted inside and outside, making the pressure resistance performance lower, easily causing leakage, cracking, and even water pipe breakage.
Experts' suggestions for retrofitting: Renovated second-hand houses that have used for more than 15 years, must be retrofitted to the Sheung Shui Pipeline and selected new-type water pipe materials. Common are: New plastic pipes such as PP-R and PE, and stainless steels of higher grades. Tubes and copper tubes. Do not use aluminum plastic pipe; in the decoration will be buried in the water pipe, but it is best not to bury it in the ground. In the transformation of second-hand housing wall and ground should also pay attention to: the original decoration of the old room are generally used are hydrophilic gypsum putty, need to be completely removed after the use of water-resistant putty.
Case 3: Circuit Reconstruction Security Buried
Risk factor: ★★★★☆
When the ceiling or the wall is removed, the original circuit is likely to be destroyed. The original socket circuit of the old house may not have a grounding wire, which does not meet the electrical safety standards.
Experts' suggestions for modification: When demolition and modification of the circuit, first open several socket boxes and check the nozzles of the originally installed wire tubes. If the wire tubes are rusted, they should be discarded. If the wire tube is well preserved, the wires in the tube can be replaced directly. If the tube is made of a plastic copper wire that meets the standard, it can still be used; the newly added power socket and lighting circuit are best taken from the distribution box alone. Lines, because all the original circuits are installed, the current is calculated and distributed according to the load of each circuit branch. Any wiring or addition of sockets and lighting fixtures to the original circuit will cause a single circuit overload, which will easily cause tripping. Or burn out the power gate. In addition, the circuit needs to walk from the ground. Most of the old houses are floors of prefabricated panels. After the wires are put on the ground, the wires must be slotted, and they must be slotted.
Xiao Bian Comments: For the second-hand housing conversion, the owners have to be cautious when selecting beauty, and the water and electricity lines must be laid according to the current electricity and water standards. Especially for bearing walls, whether it is the top floor or the bottom floor, they must not fight against the wall. If they are not allowed to do so, they must be asked by the housing engineer to go to the scene and decide afterwards. I hope everyone can have a warm and comfortable home.
