Refining the five major difficulties in second-hand housing renovation

Some people think that refurbishing old houses, some things that can be preserved can save a lot of money. But in fact, for the construction party, the construction of second-hand housing is at least 10% longer than the construction of new houses, because there is a demolition of the previous period, and construction difficulties are much higher than the renovation of new houses.

Noise and trash

The biggest problem with second-hand housing decoration is disturbing people. One is noise, the other is construction waste. The decoration of new houses is generally around the same time period, but most of the second-hand housing renovation is normal living next door or upstairs, so this piece is a lot more complicated.

Solution: Before the construction, apply to the property company or neighborhood committee, obtain their permission, greet the neighbors, and negotiate construction time. Coordinating with the decoration company is mainly to remind the construction team to pay attention to the movement during construction. For example, in front of the wall and the floor, discuss the best time with the neighbors upstairs and downstairs.

High design requirements

The design of small-sized second-hand housing renovation should pay more attention to the transformation and improvement of the function of the living room. Due to historical reasons, many of the old houses built in the 1980s and 1990s in Guangzhou’s old city had poor facilities, comfort and convenience, and some even had black kitchen latrines, and they were small. Effectively improving the functionality of residential buildings and improving space utilization is the focus of designers' research on the secondary renovation of small units.

Solution: According to your own requirements, ask the designer to re-plan space applications. Remember, the purpose of the renovation is to meet your own habits and lifestyle.

Take care of the old

Some old houses have relatively thin walls and floor slabs. In particular, old houses with brick structures are mostly made of lime mortar. Cement is relatively small, especially for perforated brick walls. It is more “brittle” and must be used with caution.

Solution: Work slowly, safety is the most important, first understand the wall structure, and then develop the best construction program, remember, carefully driving the boat for thousands of years.

Complete material exchange

Most of the second-hand housing renovation when the hydropower should be re-arranged, so all the wires and pipes should be completely replaced, this is the second-hand housing renovation of the most important projects, sloppy. For example, the wires must be replaced with new ones. It is best to use 4mm wires for air conditioners, microwave ovens, and other appliances. In order to save money and save money, some people painted the original paint directly on the original wall. As a result, the wall and the ceiling began to lose paint soon after the renovation.

Solution: Completely replace all materials, especially the wires, preferably with a weak box. The layer of plaster on the wall must be thoroughly removed, polished, and then repainted with cement mortar to make it waterproof so as to avoid cracking and emptying in the future.

Hidden project difficult

The drain pipes of many old-fashioned communities in Guangzhou are mostly cast iron pipes, which are immersed in sewage all year round. Many of them have rusted or rotted, and are easily affected by external forces and cause water leakage and blockage. There are also many old house waterways with exposed plated tubes. If you want to hide it, you have to change the material. The joint must be closed. The waterproof layer must also be damaged during the demolition process and must be redone.

Solution: Do not try to change the water structure during the renovation. Especially if the toilet is shifted, if it needs to be shifted, it must be checked and accepted by the hydropower professional, and it should be treated with waterproofing to prolong the closed water test time so as to ensure that there will be no water leakage in the future.
