Buying wooden flooring is undoubtedly the highlight of home decoration, especially the solid wood flooring is hundreds of yuan per square meter, which is called the major expenditure of decoration. In the process of purchasing the floor, most consumers only pay attention to the quality and price of the product. Few people pay attention to the problem of floor installation loss. Therefore, many consumers often suffer from this problem.
Recently, the owner Mr. Wang reported to the newspaper that the actual paving area of ​​his home was 51 square meters, but after the paving, he used 56 square meters of floor space, and the loss was as high as 9.8%. The loss is less than 4%, which is more than 2,000 yuan, which makes him unacceptable.
How much is the floor installation loss?
A few days ago, Mr. Wang, who lives in the southern suburbs, told reporters that in order to purchase the floor, he turned a lot of stores, and finally selected a solid wood multi-layer floor of 268 yuan per square meter in a brand floor store. The merchant promised to give a baseboard. . At the time of ordering, the merchant said that the floor should be charged about 5% of the loss. After the merchant sent people to Mr. Wang's home to measure the actual paving area, 51 square meters, the merchant said that plus the need to order 56 square meters of floor, and then more than the actual paving situation. In the actual paving, Mr. Wang found that the skirting line sent by the merchant could not be used at all. He also spent money to buy the baseboard. After the paving, all the 56 square meters of floor space was used, but there were A lot of the remaining pieces of the floor can be reused, and Mr. Wang feels a pity. The neighbor told Mr. Wang that his family's loss was less than 4%. Mr. Wang calculated his own loss and found that it was as high as 9.8%, which made him very angry. "Why the same indoor area, the floor of the house is better than others. The loss rate is more than doubled, and it costs more than 2,000 yuan?"
The reporter learned in the interview that this situation is not limited to Mr. Wang's family. Many home improvement owners have had similar experiences. They have to discuss with the merchants, but the owners have received some remarks. What is the "different loss rate of the apartment type is not the same", "floor paving is a manual work, it is inevitable to have deviations." According to a survey of floor installation loss problems, 60% of the netizens who participated in the survey said that their home floor installation loss exceeded 5%, or even more than 7%. Malicious loss infringes the interests of the owner
According to industry insiders, since the current floor loss is determined by various sales vendors, and the normal range of each regulation is uneven, this is one of the reasons for the large difference in loss. Then, at present, the local floor traders stipulate the loss? The reporter visited a home city in the southern suburbs. The sales staff of Shenghualin floor told reporters that the decoration loss is a normal phenomenon when the floor is renovated. This part of the loss is paid by the owner. The amount of decoration loss should not exceed 5%, and the specific amount can only be known after installation. The person in charge of Dongyang Flooring and Hongwei Floor said that their floor loss was calculated at 3%, and then the short-term compensation was based on the actual paving situation. According to the shopping guide of the living house Baroque floor, the state stipulates that the decoration loss cannot exceed 8%, and the living home is generally controlled below 5% or even lower. The salesperson in the other store said that there was no specific loss regulation, and how much money was collected after the paving was lost.
A person familiar with the matter disclosed to reporters that the wood flooring market is mixed, and the loss of wear and tear is objective in the construction process. How much loss is charged by the merchants themselves, therefore, this has become a profit-making means for some merchants to change direction. Some merchants promise that loss control below 3% is actually very difficult. At present, only a few well-known brands with superb technology can do it. For a large area of ​​the floor, although the commitment of 3% but added a long back and short, actually paved down is far more than 3%. In addition, since the consumer's concept of loss is still vague, the merchant will not explain the loss to the consumer in advance. There are also bad floor manufacturers who often use malicious wear and tear to increase sales, resulting in an increase in the number of floors used, allowing consumers to spend more. Clarify the loss of cautious consumption
Shang Jun, the minister of the complaints department of the Municipal Housing Commission, said that the installation loss of the wooden floor is only normal. At present, there is no relevant standard or document regulation in the country. However, different merchants must lose their own when they sell the floor according to the characteristics of the house and the need for laying. Generally speaking, the proportion of rooms with large area is relatively low. On the contrary, small-sized rooms require more irregular floors and relatively high losses, but if they are not special rooms and special pavements, the loss should not exceed 5%. Therefore, in terms of the problem of floor pavement loss, the owner and the floor dealer can negotiate and agree according to the actual situation. When consumers buy wooden flooring, they should know in advance what floor they are suitable for, and how the manufacturers calculate the loss. Then carefully calculate the actual laying area and the purchase area of ​​the materials, and the floor price. If it is greater than 5%, it is necessary. Be wary.
The industry also introduced one of the simplest calculation methods to help consumers to know what they are, namely, the room area, the floor area × 1.05 = the number of floor panels used. In addition, pay more attention to the process of laying the floor, pay attention to the progress of laying in time, and prevent the pavers from doing their hands and feet. If the installation workers use their own professional advantages to blind the owners and deliberately increase the loss, they will infringe the rights and interests of the owners. Responsibility. In order to prevent problems before they occur, consumers should choose a reputable business and sign a paving contract with the merchant to facilitate rights protection.
