To say that the most gullible project in decoration should be the transformation of hydropower. During the construction, some foremen may say that the water and electricity quality of the developer is not up to standard and ask you to replace the wires and water pipes. Is it really necessary? The developer's water and electricity pre-installation is in line with national standards in quality and technology, and the construction water and electricity standards are very harsh, the acceptance is very strict, and there is no problem in quality. His advice to everyone is to earn more materials and labor costs.
Secondly, the water and electricity pre-laid by the developer may be insufficient, but the direction is right. It only needs to increase the water quantity at the original water pipe position without major changes. So, if you really believe that all your nonsense will be replaced, it will not only cost more money, but also the quality may not be the same. Most decoration companies will lay water and electricity pipelines horizontally and vertically, which is called "industry standard", but it has no other benefits except good-looking. It could have been point-to-point, horizontal and vertical, which increased the length of water pipes, auxiliary materials and labor costs. Secondly, horizontal and vertical paving will cause a lot of 90-degree bending of the ground. For electric wires, it is easy to bend too much, and the subsequent maintenance is inconvenient. For water pipes, it will increase the risk of water leakage.
I find that many designers of decoration companies are very strange. It seems that without renovation, their design level will not be reflected. But no matter when, demolition and reconstruction are not worth advocating, because even non-load-bearing walls will have a certain impact on the stability of houses. In addition, the identification of some load-bearing structures is not as simple as we thought. There may be a partition wall at the top and a load-bearing wall at the bottom. If the demolition is wrong, it will not only face fines, but also affect the overall safety of the house. The cleaning of construction waste is often ignored by the owners, but it is actually charged, and some companies are "all-inclusive" and do not count in the cost, which leads to the inexplicable extra cost after the workers directly deal with it. Therefore, it is necessary to talk about the treatment cost of construction waste from the beginning to avoid the other party sitting down and asking for exorbitant prices.
