"Excellent work by Hunter K., Jacey H., and Teddy F.!!! I was so impressed with the encapsulation of my crawlspace that I immediately scheduled for the crew to come back and encapsulate my basement! They were very careful and attended to details, communicated every step of the process, made sure I understood what they were doing and why, and that I was pleased with the work. The space looks, smells, and feels amazing!!! Thank you to the best crew around!!!"

"We are very satisfied with their work. Workers were very professional and the hardest working group I have ever seen. They installed an under the floor drainage system along a 60 foot basement wall. We have had no water on our basement floor since it was installed 2 months ago. We have had multiple downpours since then. We had water on our basement floor every time it rained before their installation. We highly recommend them."

"I was very happy with the estimate I got from Corey, and he explained how things were going to be done. I had the waterproofing done on one entire wall of my basement, and a sump pump put in, on one of the coldest days of this year, and the guys were great, they put up plastic to keep things from getting dusty, and they were done in 1 day!! I was very impressed! I did have a tiny leak, a few days later, but the company sent someone out almost immediately, and that was resolved. I highly recommend this company, and know that I went with the best!!!"

Basement Waterproofing questions, answered by experts

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.
