What are the tricks of the decoration company's quotation?

General decoration users have less decoration experience and are easily fooled by decoration companies. Simple references can confuse users. Next, let's take a look at what's wrong with the quotation of the decoration company: 1, construction technology: Generally speaking, the construction technology of each process will be described in detail in the quotation of decoration, but we may not understand those professional words, but it depends on the brand of the materials used for careful decoration and whether there is a detailed explanation. 2. Material specifications: a detailed quotation for the decoration project. For the materials used, each specification should be written at the back, including brand, specification, unit price, quantity and total balance. The materials are clearly written, and some decoration companies erase the specifications and quantities in order to take advantage of loopholes, which will lead to great problems in the future, various costs increase and various quality problems. Be sure to check the quotation. 3. Loss: The quotation sheet for decoration is generally per square meter, so the loss is not clearly marked. However, the decoration quotation provided by the decoration company must include unit price and total price. Material loss will occur in many decoration processes, so the decoration company must indicate the reasons for the loss in the decoration quotation. At the same time, it should be noted that the basic loss of any project will not exceed 10%. If it is found that it exceeds this ratio, the other party should be asked to give a reasonable explanation. 4. Give up low and take back: Some building materials merchants will negotiate with home improvement designers, and designers will use their materials in the design, and building materials merchants will give designers a certain rebate. In this case, some designers will intentionally use these materials with kickbacks when designing, and the price of these decoration materials with kickbacks is higher than the market price, which increases the decoration cost of the owners. 5. Decomposed decoration quotation: Judging from the quotation in the current decoration market, many decoration companies quote through price decomposition. The common practice is to decompose a single project into several sub-items at will, and quote each sub-item separately; When quoting, the price will be increased accordingly or a small number of items will be calculated repeatedly. For example, we usually quote according to the price per square inch, excluding handles and locks, but some decoration companies break it down into door leaves, door covers and hinges. Because the owner doesn't know much about the decoration project or the decoration company decomposes it in a hidden way, so that the owner doesn't know it, but the total decoration price increases unconsciously. 6. Make a virtual discount: the decoration company first gives the decoration quotation according to the owner's demand, and then gives some discounts according to the owner's desire for discounts. On the surface, the owners get a lot of concessions, but in fact, due to the high initial quotation, even if the concessions are given, the decoration expenses actually paid by the owners are often higher than the actual costs. 7. Common supplement: (1) Wall demolition and renovation: All the quotations of decoration companies basically indicate the cost of wall demolition and renovation, but the problem of temporary demolition is easy to occur in the actual decoration process. For example, at first, the owner didn't know that there was a ground beam on the wall, but it was discovered only when it was halfway down. If this item is not included in the budget contract, he will directly quote 100-200 yuan. To do or not to do. At this time, the owner is hard to recognize! (2) Shovel the wall: not for decoration. It is generally not known that shoveling the wall skin includes shoveling the wall skin (removing the lime layer and cement mortar layer on the wall surface). If the wall is uneven, it should be leveled. I just think shoveling a wall is as simple as shoveling a wall. When the construction finds that the concept of contract is vague, it will start to wrangle, so the contract should be broken down and marked according to the process. But this still has advantages and disadvantages. At first glance, it's cheap, but it's not cheap when the items add up. (3) Brick-to-brick: The cost of conventional brick-to-brick, flat brick-to-brick and vertical brick-to-brick is the same, but the cost of oblique brick-to-brick, mosaic or laying special-shaped brick will increase by 20-60 yuan according to the specifications and technology, but some companies will not tell you this directly. 8. Demolition: A project is divided into several projects, and the unit price has come down, but the total price has gone up. This trap is a common trick of decoration companies. 9. Unit conversion: the project that should have been quoted in square meters should be quoted in meters. 10, fiddling with engineering quantity: Many companies often take engineering quantity as a trap to obtain higher profits. 1 1, the unit price of the main material is playing tricks: it is not a brand-name product with a very clear price, but an unknown product, so that consumers do not know the price. 12, quote the price of accessories: consumers have detailed research on the main materials, but they don't know the price of accessories, so decoration companies often use the design trap of accessories. 13, the prices of main materials and auxiliary materials are not quoted separately: 14, double counting: the door installation has been included in the hinge, the floor nail has been included in the floor installation, and then an engineering "hardware" was added at the end, with the price of 3,000 yuan. When the budgeter asked what this material was, the answer was I don't know. This is a trap commonly used by small decoration companies in previous years, but it is used less now. 15, the area measurement is false and exaggerated: some decoration companies will deliberately exaggerate the construction area in the budget to obtain higher profits. Especially for walls, a few decoration companies will report more painting area. In each decoration order, the profit is about 10% to 20% by falsely reporting the area. In most cases, the work of measuring the decoration area is done by the decorator. Even if the owner takes a pen and paper to record on the side, the gesture change of the decorator is not easy to detect. The original length of 25 cm is likely to become 28 cm. There are 3 centimeters more here and 3 centimeters more there, and all these extra materials are in the pocket of the decoration company. "
