As a homeowner, you should not just leave everything to the contractor. You should also do your own work by doing your research to find the best company. A bit of precaution will help you in the decision process, and at the same time save you tons of money.
Take note that basement waterproofing is not just all about good sealing. There are several elements that you should look into, such as the following:
Cracks in the Foundation
A lot of people do not see a relationship between foundation cracks and basement waterproofing. But then, there is really a connection: water can get into a home through wall and floor cracks. When this water gets inside, it can damage anything in its path, and also ruin all wooden materials below the home, including wooden support beams and floor joists. This moisture can also contribute to the growth of mold and mildew.
The gutters of your home play a major role in flooded basements. Essentially, if there is no water puddling up alongside your basement walls, there will be no water that seeps into the basement over the top of the foundation. Thus, a good gutter system with an extended downspout guarantees that the pooling water is directed in the opposite direction of your home.
There are many other areas of the home to check that could act as entrances for water to get into your home. Only a true basement waterproofing professional will know where to look!
