"We had our basement waterproofed last year and were very happy. This year's project was adding two support beams. Again, we were very happy with the quality of the work and the people we dealt with. Both Gunnar and his team and Perfecto were skilled, efficient, and very professional. Highly recommend."

"All of the floor joists in my family room were rotted and/or collapsing due to prolonged water damage. Atlas staff, including the salesman Jim and engineer reviewed the situation and recommended a waterproof membrane and pitching the sidewalk on one side of the building away from the building. When water tested this only provided a partial fix of the problem. We eventually decided on drain tile and adding a concrete sidewall around the entire perimeter. This appears to have been the addition step needed. Only time will tell. There is a 10 warranty against water seepage. Robert and his team were great to work with. They were timely and responsive to my questions and concerns. The project took a little longer than expected due to having to add the drain tile and additional walk way."

"My husband and I had a wonderful experience with The Real Seal in July 2024. They fixed a bowing foundation and waterproofed the basement for future finishing. Their team was prompt, respectful, organized and thoroughly educated us on the drainage tile system, installation process and prevention. Thank you, Real Seal for being the flawless first step to our dream basement/family space!"

"I had been having water leakage problems into my lower level family room for quite some time. Real Seal correctly diagnosed the problem, quoted a reasonable price, showed up to perform the work per agreed upon date and fixed it permanently. Even with the wet spring this year, I have not had any further water leakage problem. I highly recommend this company"

"They are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

Basement Waterproofing questions, answered by experts

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

Yes, you can technically make a crawl space liveable, but the only way to do so is by converting it into a basement. While some crawl spaces are big enough to walk through and store large items, they lack appropriate insulation and space to be liveable.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.
