Minhang second-hand housing decoration company, commander in chief decoration is not bad, but also the top decoration company in Shanghai. Second-hand housing decoration selection commander and other experienced decoration companies are safer. Here is a summary of some matters needing attention in the decoration of second-hand houses.

One is not to relax the waterway engineering.

The waterway must be thoroughly inspected. If the water pipe is aging, it must be replaced immediately. Also pay attention to whether the water pipe layout is reasonable. Before the renovation of second-hand houses, it is necessary to carry out 24-48 hours of water storage and leak detection experiments on bathrooms and kitchens to check how the original waterproof works are done. If there is no water leakage, it proves that the waterproof treatment is done well; If there is water leakage, be sure to waterproof it again. After waterproofing, when the ground is completely dry, tile will be laid for overall decoration. Moreover, when the toilet is changed from squatting to sitting, the waterproof treatment of the lower outlet of the toilet must be done well. When designing and decorating the top of the toilet, we should pay attention to the convenience of disassembly, which is conducive to future inspection and maintenance. At the same time, it should be noted that no dead ends can be left after construction.

Second, the circuit transformation can not be ignored.

Second-hand houses generally have the phenomena of simple circuit distribution, aging wires and illegal wiring, which can hardly meet the electricity demand of modern families, and must be completely reformed and rewired when decorating. If it is found that the original lines use aluminum wires, they must all be replaced with copper wires with a cross section of 2.5 square millimeters. For the lines of high-power electrical appliances such as air conditioners, lines with a cross section of 4 square millimeters should be set separately, and PVC insulated conduits must be used when burying the lines. In addition, the new national standard stipulates that the number of fixed sockets in residential buildings should not be less than 12, but there are still many existing sockets in second-hand houses that cannot meet this standard. If a large number of mobile sockets are used, when the current load increases, the mobile sockets will produce abnormal high temperature due to poor contact, laying a hidden danger for electric shock and electrical fire accidents.

Third, the "hidden project" is hidden after it is taken apart.

A large part of the quality problems in the decoration of second-hand houses are caused by improper construction of "concealed works". What is a "concealed project"? That is to say, in the process of construction process sequence, the work of the previous process ends, and the part that can not be inspected by the next process is called "concealed engineering". Therefore, in the decoration of second-hand houses, special attention should be paid to "concealed works". For example, whether the pipes, lines and equipment of various facilities such as water supply, air conditioning and ventilation in the ceiling have been tested for tightness, electrical insulation and resistance, whether the connection is firm, whether the joint practices meet the requirements, and whether the flammable materials have been treated with fire prevention and flame retardant, etc., all belong to the scope of "concealed engineering" and cannot be inspected after the first installation. Insiders suggest that it is actually a good opportunity to reopen these parts and eliminate hidden dangers when transforming old houses. The owner must strictly check and remove the "hidden works" left over from the past.
