"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."

"They did a quick and good job of replacing our water heater. Called again due to standing water in our yard after every rain. They came out and installed a drain and tied my downspouts into it. They also put the excess dirt against the house to improve the grading. I can say after the fall rains and the repeated freezing/thawing in winter that the drain has kept everything dry and we have had no more water issues in the basement. I would recommend these guys."

"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."

"Wyatt did an awesome job. This was a major job. I had a water pipe break just under the house foundation. They initially believed it could be reached from the outside, but determined the break was just under the foundation. Because of this, they needed to break up the concrete floor in the basement at the outside wall. They carefully removed the floor molding and the wood boards before jackhammering a 2 foot by 1 foot hole at the edge of the floor at the outside wall. They were very neat and tidy. The broken pipe was fixed in less than a day. They then cleaned out many of the faucets and came back the next day to adust the water pressure and be sure all faucets were working properly. They kept us informed at all steps of the process and the cost was less than their estimate. We highly recommend Wyatt for your plumbing needs."

Basement Waterproofing questions, answered by experts

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.

A sump pump can remove excess moisture from under a house if standing water is present. Other ways to protect your crawl space from moisture include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home’s foundation can prevent moisture from getting into the crawl space in the first place.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.
