Generally speaking, the renovation price of old houses will be higher than that of new houses 10%-20%. But in fact, there are many useful parts in the original decoration of old houses. You can save a lot of money if you maintain the decoration status of these parts or minimize the changes.
Counting the details, the renovation of old houses is more "economical"
Demolition and renovation, 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 decoration of second-hand houses, once there is a change, it may bring a lot of expenses, so the most economical way to transform second-hand houses 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?
Kitchen and bathroom tiles
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the tiles used for kitchen and bathroom have not appeared a lot of hollowing and falling off, and the styles are still outdated, they can be replaced.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.
Wall treatment
Most of the old second-hand housing walls will have cracks, which is caused by poor handling of the 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, local plastering can be considered to prevent cracks, and the cost of plastering is about ten yuan per square meter.
Waterway reconstruction
Waterway reconstruction can be described as "major surgery" 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 modification
Circuit reconstruction is also the highlight of old house reconstruction. 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 socket "* * *" enjoys a dangerous way of using electricity with one wire, which is easy to cause excessive circuit load and old wires are easy to cause fire.
At present, the circuit layout of most families is divided into three paths, that is, switches, sockets and high-power appliances each take one path, and the wire diameter is
2.5 square millimeters, if the old house circuit is also in this layout, then the circuit as a whole can be considered as a pass, and sockets and switches can be added locally to meet the power 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.
Don't change the drainage in the bathroom at will.
Some old bathrooms have side drainage, and the height of this bathroom is much higher than that of the living room and bedroom. 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.
Key monitoring concealed works
Concealed works such as water circuit renovation will directly affect future life use, so we should guard against death in the process of renovation. 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.
Cooling holes should be reserved for the heating package.
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 prevent the gypsum board ceiling from cracking and deformation after being baked by the hot air for a long time.
Be cautious in rebuilding old brick-concrete houses
Breaking the wall and knocking on the ground is often an inevitable project in the renovation of old houses, but some old houses with brick-concrete structure need to be cautious in demolition and renovation. 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 consider the structure and safety of the house, and make bold innovations on this basis, otherwise once we start construction, it will cause irreparable losses.
The above is how to decorate the second-hand house, which is the most economical. Suggest that friends can.
Try it, or you can try the decoration gallery, and the effect is good.
