First, water and electricity installation. According to the survey, more than half of the families that caused the fire were caused by electric leakage, so be sure to buy good switches and sockets. Everyone was full of curiosity when he was a child, so families with children must choose safety sockets, which have special protection measures. Waterproof sockets must be used in bathrooms and kitchens. When we usually do things, it is inevitable that we will get some water. In addition, special sockets for air conditioners cannot be mixed with other sockets. Sockets must be orthodox, and it is best to buy them in the formal building materials market.

Second, waterproof. Pay more attention to the waterproof of the bathroom. If the waterproofing is not done well, it may leak downstairs, complain to the neighbors downstairs, or seep into your own wall, and the wall will be moldy. It will be too much trouble if it is repaired later. Therefore, it is recommended to do waterproof work in advance when decorating to prevent future troubles.

Third, the range hood. Don't save the kitchen range hood, choose a range hood with large suction, so that the kitchen won't be greasy, and it's okay to fry peppers at home!

These are all places where you can't save money in home improvement.
