Excuse me, how to decorate the second-hand house is the most economical? Generally speaking, the renovation price of old houses will be higher than that of new houses 10%-20%. But in fact, there are many available parts in the original decoration of the old house. You can save a lot of money if you keep this part of the decoration state or minimize the changes. Renovation of old houses is more "economical". Old decoration, wall treatment, structural transformation and water circuit transformation all make the decoration of second-hand houses very expensive. In fact, there is no need to spend a lot of money on second-hand housing decoration, because there is still room for old decoration. If they are used, the whole renovation cost will be economical. Meet the use requirements and minimize changes. For the renovation of second-hand houses, once there are changes, it may bring a lot of expenses. Therefore, the most economical way to rebuild the second-hand house is to change the existing layout of the room as little as possible, but only if it can meet the needs of family members. If you "sacrifice" future functions in order to reduce costs, it will bring great inconvenience to your life. Then, what links can be reduced in the renovation of second-hand houses, thus reducing costs? The cost of kitchen and bathroom tiles can account for at least 10% of the cost of main materials, so if the second-hand house has not been renovated for a long time, the tiles used for kitchen and bathroom have not appeared a lot of hollowing and falling off, and the styles are still outdated, they can be replaced. Replace the aging parts such as the ceiling of the kitchen and bathroom space with new materials, and the whole kitchen and bathroom space will be completely new. Most of the second-hand housing walls that have been treated for many years will have cracks, which is caused by poor treatment of grassroots walls. If the wall is not water-resistant putty, it is easy to lose dust and powder, then such a wall needs to be treated at the grass-roots level again. However, if the original wall is waterproof putty, you can consider using local plastering to prevent cracks. The cost of plastering is about ten yuan per square meter. Waterway reconstruction Waterway reconstruction is a "major operation" for second-hand houses, so it costs a lot. Generally speaking, the decoration of waterways by home improvement companies is charged according to the difference between open pipes and concealed pipes, and the price is about 80 yuan per meter to 90 yuan, so minimizing waterway decoration is of great help to reduce the overall decoration cost. Whether the tap water pipeline needs to be rebuilt, we should first check whether the layout of the existing waterway meets the needs of family members, and if so, we can maintain the position of the existing waterway. Then check the material of the water pipe. Many water pipes in old houses are galvanized pipes. After years of use, the pipe wall will produce rust, which will affect the water quality. In addition, galvanized pipes will "sweat" in summer, and a large number of water droplets will condense on the outside of the pipe wall. If they are not treated with anti-corrosion and moisture-proof, the walls will be damp. Circuit transformation Circuit transformation is also the highlight of old house transformation. It is very important to judge whether the circuit needs to be reformed, which not only involves the increase of the overall reform cost, but also relates to the safety of household electricity in the future. Most old houses with a room age of twenty or thirty years have only one circuit. This kind of switch and socket "* * *" share a wire, which is more dangerous and easy to cause excessive circuit load, and the old wire is easy to cause fire. At present, the circuit layout of most families is divided into three paths, namely, switches, sockets and high-power appliances, each with a wire diameter of 2.5 square millimeters. If the circuit of the old house is also in this layout, then the circuit as a whole can be considered as a gateway, and sockets and switches can be added locally to meet the electricity demand. However, the upper limit of 2.5 square millimeter wire load is about 5500 watts, so power must be considered when choosing bathroom and kitchen appliances. For example, the fast-heating electric water heater used in the bathroom, the wire diameter of 2.5 square millimeters is far from enough. Therefore, when transforming the circuit, we must communicate with the hydropower designer and try to carefully consider the electricity demand of family members. Bathroom drainage should not be changed to some old-fashioned bathrooms for side drainage at will. The floor height of such bathrooms is much higher than that of living rooms and bedrooms. Once changed, it will affect the floor structure of the bathroom and even cause inconvenience to the residents downstairs, so this drainage method cannot be changed at will. At the same time, if the squat sanitary ware is changed into a toilet, it needs to be waterproof again. Focus on monitoring concealed works, such as water circuit transformation, which will directly affect future life use, so we should guard against death in the process of transformation. After years of use, the original decoration of the old house will be outdated, so there may be water leakage. After re-waterproofing, it is necessary to conduct a 24-hour water avoidance test to verify whether the waterproof layer is intact. Generally speaking, the waterproof layer of shower room is 1.8m, the height of other wall waterproof layers is 1m, and the waterproof layer on the ground is 30cm higher. If there is no waterway reconstruction during the decoration, it is also necessary to check whether the waterproof layer is intact. Punching and slotting in the decoration process may damage the waterproof layer. Therefore, if the tiles are removed from the decoration of second-hand houses, they should be re-tested to ensure that there is no problem with the original waterproofing. After the circuit transformation, it is necessary to check whether the sockets and switches can be used normally and whether the installation position meets the original requirements. Some old houses on the top floor have heating pipes, which affect the indoor beauty. The simplest way is to wrap these pipes near the roof as a ceiling. It should be noted that the circulation and flow rate of these heating pipes are often better than that of radiators, so they will make the room warmer in winter. When winding the heating pipe, enough cooling holes should be left, which can not only let the hot air flow out, but also avoid the gypsum board ceiling from cracking and deformation due to long-term baking by the hot air. It is inevitable to knock on the wall and the ground in the renovation of old brick-concrete houses, but some old brick-concrete houses need to be demolished and rebuilt with caution. The wall of brick-concrete structure plays the role of bearing and earthquake resistance first, and then plays the role of enclosure and separation. If the load-bearing wall is destroyed only to realize the idealized spatial pattern, the load-bearing and seismic capacity of the wall will be weakened, resulting in potential safety hazards. Therefore, when demolishing, renovating and renovating, we must take into account the building structure and safety issues, and make bold innovations on this basis, otherwise, once the project is started, it will cause irreparable losses. The above is how to decorate second-hand houses to save money. I suggest that friends can try it, or try to decorate the gallery, and the effect is good.
