The renovation of this large project is not only costly but also very tedious. We told you before that we must prevent decoration traps during renovations. We must refine and refine the budget, and we must write down the contract in every aspect. But don't think that these are written in the contract and they will sit back and relax. As the saying goes, it's hard to avoid light-bodied guns. We also need to beware that some unscrupulous decoration companies purchase building materials to get kickbacks, and the construction process can be used as a substitute for shoddy items, and so on. Well, now, everyone and Xiao Bian went to see the three major arrows of decoration: the order of price increase procurement jerks! When is the purchase of furniture materials better? During the renovation process, many consumers will purchase building materials such as cabinets, tiles, floors, and sanitary ware. One to make space design more in line with their own requirements, and second, to avoid bad decoration companies to profit from. Many materials can be purchased in advance before the renovation project starts, and many hypermarkets often offer advance ordering promotions. To remind consumers is that if you do not have very clear requirements for space design, or after selecting the building materials products after communicating with the designers, it will help maintain the integrity of the space style. Of course, if you have a lot of space design ideas, you can save some costs by buying in advance. The purchase time of general building materials products is best suited to the completion of the overall demolition project. At this time, the main structure of the space is roughly determined, and the locations of tiles, floors, and cabinets are all clearly defined. The area determined by each space is clarified, and the purchase of building materials products can also better control the quantity purchased.
