After all, second-hand houses are different from new houses, and many owners even modify the internal structure of the house. Then, you should know the following things to note!
Note 1: Do not demolish load-bearing walls indiscriminately; demolition of load-bearing walls without permission is not only a serious hazard, but also violates relevant national regulations. Load-bearing walls are the main body of the house. Once problems occur, not only will you suffer economic losses, but you may also be subject to legal sanctions. Pay attention to the walls that can be removed and modified, which ones are removable and which ones are not. Therefore, please consult the property owner before demolition, because the property owner will have some structural drawings of the house. In the absence of drawings, try not to demolish walls such as doors and exterior walls; and use a ruler to measure thicker walls, which must be load-bearing walls; and the walls in bedrooms must be load-bearing walls that cannot be demolished.
Note 2: Water and electricity renovation; Generally, the original water pipelines have many unreasonable layouts or are corroded, so the water pipelines must be thoroughly inspected. If the original pipelines are galvanized pipes that have been eliminated, they must be replaced with copper pipes, aluminum-plastic composite pipes or PP-R pipes during construction. Recently, more PP-R pipes have been used. This is Must be replaced.
Note 3: Circuit modification; Second-hand house decoration generally has simple circuit distribution, aging wires, illegal wiring, etc., which can no longer adapt to the electricity needs of modern families, so it must be completely transformed and re-done during decoration. wiring. Since aluminum wire was used in the past, we need to replace it with the copper wire we use now, and use PVC insulated wire conduit. The lines for installing high-power electrical appliances such as air conditioners must be run separately. Simply put, it means starting over. As for the socket issue, you must add more sockets, because the sockets in second-hand houses cannot reach the number of current electrical appliances, so this must be changed during decoration
Note 4: Renovate tile floors; smash wall tiles and When laying floor tiles, avoid debris blocking the sewer; only solid wood floors, solid wood composite floors and bamboo floors with a surface thickness of 4 mm can be renovated. In addition, partial renovation will also cause the difference between the old and new floors. Therefore, consumers cannot blindly renovate the floors
Note 5: Decoration on three sides; renovation of the walls, floors, and ceilings of second-hand houses is the most effective It is easy to overlook that the original decoration of old houses generally uses hydrophilic gypsum putty, which needs to be completely eradicated and replaced with water-resistant putty
Note 6: The closed water test is the most important and must be Indispensable.
