"Groundworksâ listened to our input and throughly evaluated the requirements to support the basement walls and prevent water from coming in. They were on time and communicated clearly and timely. The Foreman did an evaluation and recommended a couple changes to the plan that I agreed with and weâ re beneficial. The 3 workers knew what they were doing and worked hard. I appreciate the manner they communicated and they were very friendly. Overall, they did a great job!"

"Wow I got a pro when I hired Kevin from KJ Drywall to waterproof my basement. Not only did they do an excellent job but went beyond what they contracted to do. I recommended them to neighbors and KJ (Kevin) treated them in the same professional and efficient manner. Highly recommend KJ Drywall."

Basement Waterproofing questions, answered by experts

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

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.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.
