The owner should require to calculate the actual area, such as wardrobe, shoe cabinet, etc., and take "items" as the unit as little as possible to avoid errors in the decoration process.
Second, "omit" some hard decoration materials. Some main materials were deliberately omitted from the decoration quotation. The owner was attracted by this quotation with reasonable overall price and signed the contract gladly, but in the following renovation process, the owner will continue to add money for these malicious "forgetfulness" of the decoration company.
To resolve this risk, the owner must ask the decoration company to write all the main materials clearly in renovation contract or the agreement, and indicate whether it is the decoration company or the owner himself.
Third, fuzzy quality, grade and specification.
This is the usual trick of informal decoration companies. Although it is stated that some materials are needed and the quantity of materials is indicated, it is not stated what quality, brand and specification materials are selected.
The owner shall require each item in the quotation to explain the elements of the materials in as much detail as possible.
Pay attention to check whether the relevant materials are purchased according to the specified requirements when decorating.
Fourth, to reduce the individual price, the owner will generally consult friends who have already renovated in advance, or go to the market to know the price of a certain material, but the information he knows is often one-sided.
For example, the owner knows the current unit price of floor tiles, but he doesn't necessarily know the labor cost of floor installation and tiling, so he lowered the price of floor tiles, but suffered a loss in labor cost (the current labor cost is really expensive).
Therefore, when the owner looks at the decoration quotation, he should not only look at the individual price of a certain project, but also look at the expenses of labor, loss and other aspects as well as the expenses of other projects.
Fifth, the construction technology is vague. It is a common problem for most car owners to look at pictures without looking at text descriptions. They always think that a digital error will cause losses, but the text description can't be tampered with. That was not the case.
Whether it is wall coating construction, ground construction and sewer construction, they all have their own construction technology requirements. If one process is missing in the middle, it may bring you a lot of trouble in your later life. Most of the problems such as paint peeling on the wall and water seepage in the bathroom are caused by poor decoration construction technology.
The bathroom is more than 1.8 meters waterproof.
Waterproof should be brushed twice, closed water test and so on.
