How to Select the Best Waterproofing Contractor

Contractor-iStockWondering how to choose a basement waterproofing contractor? You can investigate on your own to find the right waterproofing company or contractor to meet your needs by doing the following before having any work started:

  • Check the Better Business Bureau (BBB)
  • Make sure company or contractor is Licensed and Bonded
  • Request and check References
  • Look into the Company’s History
  • Find out if company has earned any Certificates or Awards
  • Have a Written Contract spelling out details


The Better Business Bureau (BBB)

The Better Business Bureau is a repository for customer complaints and ratings on job performance. The BBB investigates the company’s handling of each complaint. The information can easily be found on the BBB’s website for the local area and will indicate to what extent a company guarantees or stands behind their products and/or service.

Fully Licensed & Bonded

No one should ever hire a contractor that isn’t fully licensed and bonded to work in that state. Unless a fully licensed professional waterproofing contractor, who is certified, completes the work the warranties on any waterproofing products used on the job will most likely be null and void.

Customer References

Any company in good standing will gladly give you references from current and former customers. Providing references to potential customers is a very common practice and a great way to find out what you need to know about the company you are considering hiring. Do not be shy about asking for contact information on the customer and details on the scope and length of the job. Personally call each reference and inquire about all aspects of the job.

Company History

Companies can be here today and gone tomorrow and this will easily be uncovered when a company seems to have no discernible history. A reputable service provider, such as a waterproofing company should easily have a verifiable, established company history, which would indicate how well they take care of their customers.

Certificates & Awards

Leaders in the basement waterproofing industry will surely have earned certificates and awards in recognition of their ability and track record of doing outstanding work and providing excellent customer service over the years.

Agreed Upon Written Contract 

A fully agreed upon written contract is always necessary to protect all parties. If a waterproofing company is willing to do the job in the absence of having everything in writing that should raise a red flag. Every line should be read and initialed to indicate you understand every word in the contract. Inspect the contract front and back for any fine print. A valid contract would include all the pertinent details regarding the job to be done, an estimate of the length of time it will take to do the work and of course an estimate of the total cost. Make sure you receive the guarantees and warranties in writing and have a full understanding of their scope before any work begins.

  1. My husband and I just moved to an area where it rains a lot, and we recently had a neighbor suggest that we get a waterproofing contractor. Apparently there are floods here a lot, so it is better to prevent them than try to clean up afterwards. I like the tip you give of looking for someone that has a verifiable, established company history that explains how well they take care of their customers. It would probably also be smart to make sure they have a good website that is easy to manage so that you can get information you need quickly.

  2. This is a great tip. If you or someone you know is in need for a reliable contractor, we recommend Decorative Concrete Kingdom ( It offers a comprehensive decorative concrete contractors directory, offering contact information for contractors all over the country. Check out their contact information, website, galleries of previous work, and more. Many of these contractors offer SANI-TRED waterproofing and are a great resource to consult.
