"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"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!"

"Alfonzo arrived on time and was extremely polite and professional. Him and I looked at the work I wanted completed together. He gave me two options. A more in detailed option and a less detailed option. Both prices were within the quoted amount. We went with the more detailed approach because of where we wanted our garage heater placed. Alfonzo was here for three hours. He had a lot of cuts to do to make this work. The outcome is awesome. Looks great in the garage and in my basement. He even took off his shoes every time he came in my home and carried them to the basement to finish his work. I would highly recommend!!!"

Basement Waterproofing questions, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation.
