"We had our basement waterproofed in May 2019, the crew was out for 3 days. They also did some landscape grading. It's been 1.5 years and no problem. Very professional company. If I have any questions Carl or his wife, Jayna, respond promptly. I would highly recommend ABC for waterproofing a basement."

"Excellent - Josh, Mark, and the team tore out 3 feet of concrete floor to replace the base of the stack pipe then worked their way up. Project took 2 days, first floor was completed and back on line the first day. Second floor and cleanup was done the second. 100 year old home so none of the old plumbing was easy to access. Very happy with results and with the professionalism of his team."

"I had a pretty bad flood in my basement after the heavy storms that came through back in June. I realized that my sump pump was the reason so I needed to replace it. I wanted something with more horsepower and after doing some research, I decided an ejector pump would work best for my home. Tyler was very friendly and understanding of my situation. He told me about some options, gave me the literature and a fair price for what I wanted. He and his team were very professional and attentive and definitely knowledgeable about the equipment and installation process. I was a little apprehensive about going with a company that’s just starting out, but Tyler gave me a good feeling about their company and products. I’m very happy with the installation and the service I received. I wouldn’t hesitate to contact them again (although I hope I never have to) for any future needs. We have multiple rental properties, so I would call him first if I ever need service at any of them. A+++"

"I wish I had hired them first! I hired another company to fix my moving bowed and shearing basement walls. They were primarily a waterproofing company, but said they had the solutions to my issues. 3 months after they were complete, my walls cracked and shifted again. (Note, in the attached photos, the patchwork quilt on the walls was the OTHER company.) OBA fixed my issues the correct way. And they were great at every step. The work crew Caleb, Delontae, and Dylan were fast, efficient, and cleaned up when they were done. Caleb made sure to explain what was happening as they did the work and ask if I had questions. The work was thorough, and I feel good about it. And even better, they'll be out in 6 months to ensure everything is working as it should and make adjustments if needed."

"I called WyattWorks based on Angie?s list reviews and a couple word ?of-mouth recommendations.   They were outstanding!  The receptionist was very helpful.  She helped to get someone out that same day, since I would not be home again  for several days.   Water had been backing up through the drain in my basement and was particularly bad on the day I called.  Ben C. and an assistant  called to let me know when they would arrive, and they were on time.  Ben listened to my description of the problem, examined the situation and prepared a quote for the work .  I received a significant Angie?s list discount, which was awesome.  After agreeing to the price, they set to work.  The culprit proved to be masses of small roots which had worked their way into the sanitary sewer line through the joins in the clay pipes.  The work took longer than they expected (4 hours) and required the use of their in-line camera and hydrojet to clear the lines, working both from within the basement and from the clean-out in the yard.   They stuck with the job until all roots were removed,  and then  cleaned up what ended up being a very big mess in the basement.  Ben was polite, focused, and skillful in handling the problem. He explained what he was doing and answered all my questions. Importantly, they stood by their original estimate even though it took longer than they anticipated.  . They did excellent work, and I will certainly call them again if I have plumbing issues.  You should call them too!

Basement Waterproofing questions, answered by experts

The best basement waterproofing method depends on the specific issue causing the water intrusion. For minor problems, simple solutions like installing a properly functioning gutter system to direct runoff away and grading the soil to slope away from your foundation can be effective.

If you have more significant water problems, the solution will need to be more robust:

  • For standing water on the basement floor, a floor drain or a sump pump system may be the best solution.

  • For water pooling around the foundation, installing an exterior French drain can intercept water before it reaches the basement walls.

Other effective waterproofing methods, which can be used depending on your home's specific needs, climate, and soil type, include sealing the interior walls, landscape alteration, installing interior drainage systems, and using a dehumidification system to control moisture levels.

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.

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites
