Have you had to repair a wet basement more than once? Then it might be time to call in the professionals. Most of the DIY waterproofing techniques, as promising as they seem, are woefully ineffective. Some of the common mistakes people make include using waterproof paint over existing paint; it will not work.

It takes an expert to be able to quickly identify the source of your water problem and know exactly how to handle it. So with the wide range of waterproofing companies available, how do you make the right choice?

1. A good waterproofing company is licensed.

The waterproofing company you choose must be licensed. This will give you some assurance that they have at least a certain minimum quality requirement and cannot just disappear if your money has done little or no work. It will also help if you can take legal action against the company if you later discover that the quality of service provided is below expectations.

2. A good waterproofing company is profitable.

As with any other household expense, price is very important. Cheaper doesn't always translate to better, but make sure you're not being fooled either. Compare the work to be done with the estimates provided and select the company that offers you value for money.

3. A good waterproofing company can provide references.

Ask the company to give you references, clients who have previously hired their services. This is useful in two ways. The company's reaction to your request will speak volumes about your customer relationships. Also, it is only a person who has had contact with the company who can tell you some things about them such as if the workers are kind, with what respect they will treat your home and if they finish the work on time.
