5 Questions to Ask Your Basement Waterproofing Company


The Internet makes it easy to hire contractors these days. You just type your search query, such as “Baltimore waterproofing contractor,” and click on a few websites that come up. Right there, you have at least 5 options to choose from. To make an informed decision, make sure to interview at least two waterproofing contractors and ask them the following questions. Price is certainly an important factor, but value and quality of work are just as crucial.

Are you licensed and insured?

It doesn’t matter whether you are hiring a waterproofing contractor, a roofer or a plumber—be sure to check their license and insurance information. Don’t ever hire an unlicensed waterproofing contractor. Some waterproofing work may require permits, and you want to make sure they are obtained and followed through. Unpermitted changes to your property may lead to problems when it’s time to sell the house. And like most homeowners, you probably want your home improvement investment to increase your property’s value—not devalue it.

What is your experience with my type of problem?

You are not just looking for a waterproofing contractor—you are looking for someone who has solved a similar wet basement issue before, preferably many times. At this point, it’s good to ask how long the company has been in business and how long they’ve been using the waterproofing method they’ve suggested. It’s not uncommon for contractors to adjust or completely change their waterproofing methods. You can look at it as a sign that your contractor keeps up with the new technologies and products that enter the market. However, do inquire about reliability. If it’s a new type of membrane they’ve only used several times, it’s hard to judge how well it will perform or how long it will last.

Can you provide references?

A seasoned waterproofing contractor should have no problem sending you a list of 3-5 former clients. You don’t even need that many—just ask for two references: one recent and one from a few years back. The best testimonial you can hear is when the contractor’s customer from 3 years ago says their basement is still dry and the repairs have been holding up well.

Why are you suggesting this particular solution?

Between interior and exterior waterproofing techniques, there are plenty of ways to keep moisture out of your basement. Your Maryland waterproofing contractor should have a logical explanation of why he recommends this or that procedure. Beware of contractors who use the same waterproofing system for every job. These decisions should be made on a case-by-case basis and your contractor’s reasoning should make sense. If he struggles to explain or justify his recommendation, find someone else.

What will the finished job look like?

The quality of workmanship is important especially when it comes to exterior basement waterproofing. Both the exterior of your home and landscaping are a part of your home’s curb appeal, and you don’t want to negatively affect it with a poorly executed waterproofing job. You can ask your contractor for pictures of completed projects to check the quality of their work.
