Ms. Liu's 120-square-meter new house, a decoration company quotations 26,800 yuan, start and finish, Ms. Liu spent a total of 73210 yuan, of which more than 40,000 yuan renovation costs come from where, presumably have experienced the decoration of the owners It is clear that this is a matter of adding items and missing items. Hydropower reform is the culprit In recent days, Xiao Bian has conducted a survey of ten homeowners who are nearing the end of their renovations. Among them, there are seven homeowners whose offer price differs significantly from the final decoration cost, which exceeds the cost of the offer by RMB 30,000 to RMB 50,000. The additional fee increase for hydropower reform is 2 to 12 times of the quotation fee, and accounts for about 60% of the total renovation fee increase. Such a large inconvenience makes the owners complain and repeatedly. One of the owners told reporters: “My house has an area of ​​89 square meters. On the budget quotation for urban people's decoration, they only made a quotation of 500 yuan for this part of the hydropower reform. For the first time, I didn’t know that the hydropower reform will The problem was only to see that the total cost was very low and they signed a contract with them. In the end, this decoration company collected nearly 7,000 yuan for hydropower reform. This is 12 times higher than the original quotation.†On this issue, Xiao Bian visited a number of local decoration companies. Among them, most brand-name decoration companies had a cost of 2,000 to 3,500 yuan for pre-recovery of water and electricity for houses with a floor area of ​​about 100 square meters. The peak-light unlimited companies only receive 500-1000 yuan in advance, while another part of the company will receive an advance of 6000-9000 yuan. So, what should be the pre-charge for hydropower reform? Insiders gave an account to Xiao Bian: Take the house of 100 square meters with two toilets and one kitchen as an example. The waterway takes about 80 meters. The power in the circuit needs about 80-100 meters, and the weak electricity needs about 30 meters. The cost of materials required for the transformation of the water circuit in the market is 80 yuan/m for the waterway and 35 yuan/m for the circuit. In this way, a hundred square meters of water and electricity for the house will cost about 10,600 yuan. Craftsmanship receives more money In addition to the hydroelectric renovation part of the additional charges are not easy to be perceived by the owners, many unpredictable decoration companies clever names, the same process demolition quoted for profits, or did not specify in the quotation, for future additions foreshadowed. The owner may wish to pick up the quotation in his hands to see if there are the following problems: Demolition charges The wall surface treatment is divided into: top surface putty putty, top surface latex paint, wall putty putty, wall surface latex paint, ground treatment is divided into: ground leveling, ground cleaning, pavement, fill seam seam agent, etc. Divide the same item into multi-step charges, and increase the cost; Duplicate charges Toilet bag post and bathroom masonry column wall, wall base treatment and wall-leveling two items that belong to the same item are charged twice. Horizontal charges There is a series of horizontal re-charging items on the quotations such as materials, labor, accessories, transportation, equipment and management fees; Missing report Balcony paving bricks, door stone paving, baseboard paving bricks, bathroom ceiling, bathroom packing column, door closure, door trimming and other projects, these items are leakage of the construction side, it is likely to increase the total cost of renovation in the future Hidden danger. In addition, people in the industry told reporters that the part of the interior design is also most likely to be missed in the quotation. According to its introduction, "the modeling part is the most easily overlooked, because the designers need perfect renderings to attract the owners to sign the bills, but due to the restrictions on renovation costs, some unethical designers do not present the renderings on the renderings. The required expenses are counted in the quotation, which leads the industry to mainly want to achieve the design in the effect chart. It is necessary to increase the cost during the decoration process. The best way to prevent this kind of phenomenon from happening is to require the designer to present a true design effect. The figure, which is checked against the effect chart at the time of signing the contract, can reduce the possibility of cost leakage."
