The house also has an expiration date. When you find that circuit is aging or water pipe is aging, you need to pay attention. All this is related to security issues. Renovating old houses is different from finishing new houses, it requires a lot of energy and time, and serious aging problems will affect safety of our lives. Today I will share with you four main safety issues that you should pay attention to when renovating old houses.

1. Do not dismantle or remake load-bearing walls as you wish

When repairing old houses, load-bearing walls cannot be dismantled at will. Since a load-bearing wall is a wall that supports weight of top floor, its integrity affects stability of entire building. The demolition of load-bearing walls poses a significant security risk.

2. Beware of outdated chains

When renovating old houses, it is necessary to replace obsolete circuit, as there are many potential safety hazards. The previous design of circuit and load on wires can no longer meet needs of current household appliances, so replacement is necessary. The modification of circuit mainly includes two points: modification and branching of junction box, and determination of position of socket panel.

3. Aging waterway needs to be replaced

The problem with waterways is also one of most difficult projects when renovating old houses. Most water pipes in older homes are cast iron pipes and galvanized pipes, which easily rust, leak, and burst. Therefore, it is recommended to replace copper pipes, aluminum-plastic composite pipes or PPR pipes. In addition, there is a waterway design problem because kitchen and bathroom need to be redesigned, so the waterway also needs to be redesigned.

4. Pay attention to airing time

If it's a minor change that doesn't involve painting walls or painting furniture, it can usually be aired out about a week before moving in. However, if it is a major renovation, it will take more than three months before you can move in. The concentration of harmful substances such as formaldehyde and benzene in home is relatively high, which will have an adverse effect on human health. Therefore, special attention must be paid to problem of ventilation.
