"Let me start by saying that I would ABSOLUTELY recommend Weather – Tite Waterproofing to anyone who has water in their basement. They were incredibly professional and did top notch work. I had been getting water in my basement on and off for years. After fixing the gutters and fixing the roof it was time to address the basement. I consulted with three different Angie’s List companies (all very highly rated). Each company had a slightly different price but more importantly a different approach to resolving the problem. I picked Weather – Tite because I was comfortable with the approach that they proposed, and the price was in line with the other quotes. The work took 2 days. Day 1 was spent digging the trenches around the interior of the basement. Day 2 was spent putting in the stones and piping and hooking it all up to the sump pump. As you can imagine, putting in a drainage system is messy work – you would have been none the wiser – my whole house was spotless (including the basement) – no dust anywhere. The work was so professional that I had them come back and put up the baseboard and sheet rock. I can happily say that since the work has been completed, we have had quite a few heavy rains, and my basement has stayed dry."

"Great results from waterproofing. Turned my spring flooding anxiety to calm. As humidity rose in summer, I put in a small dehumidifier. Made basement noisy as it struggled to dry and produced a lot of heat. As temperatures rose to about 83 down there and the humidity rose to over 68%, I had same people put in a whole basement commercial-grade dehumidifier. The small unit dropped the humidity to around 50% in less than an hour. Incredible performance and have me peace of mind and peace and quiet downstairs. Temperature dropped gas as well. Weel worth the price to save my most expensive investment."

"Dean and his crew were professional, reliable, extremely neat/clean and went above and beyond, often, to make the sure work was completed to my satisfaction. They did small things not even required to make sure the entire basement area was much more than even expected. The basement has never been so dry in the 40 years I have lived here. I would hire them again in a heartbeat."

Basement Waterproofing questions, answered by experts

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.
