"Hello, we recently got an evaluation. Dylan was great and knowledgeable. He even found a diagnosis underneath our house about water running that we weren’t aware. He, with his awesome customer service, made us feel comfortable and confident on having him checking around our place to get our estimate done. Thanks s much Dylan and Mount Valley Foundation."

"Everyone we dealt with from Cantey Foundation Specialists were very professional, timely, and caring throughout the entire process from job estimate to the actual work done. While the work done did not bring all areas back completely to their original states, with the exception of one area, they were all pretty close. Realistically, It's very difficult to fix in two days what has taken place over a period of years. I am very satisfied with the job done. Grayson (job estimator) and Estevan (crew leader) were very helpful and great to work with through the entire process."

"Bought this in the spring to use before burning in the fall/winter.  Ended up moving in December and did not use it.
I'm wasn't sure how to score a company I didn't use (and not reviewing isn't really an option), so I just picked a score consistent with the average rating.

Basement Waterproofing FAQs, 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.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Installing storm windows can protect your home’s interior from heavy storms. Most storm windows are made with enamel-coated aluminum with screens and sliding glass panels. They also make your house more energy-efficient. The average storm window cost is $12,000, ranging between $4,250 and $19,850, depending on mounting, window types, glass types, and frame materials.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.
