"Mount Valley is the epitomy of an honest, fair, reliable, efficient, professional, and customer service oriented company. Our coordinator, Ryan McAlister, was extremely knowledgeable and informative during inspection of our crawl space water issues, and his subsequent repair recommendations. Ryan was like a professor explaining retrofitting encapsulation of the crawl space and basement water issues with a slab, along with discussing such encapsulation during a new build vs. standard floor insulation in a crawl space in a climate above 60% humidity. Fascinating and educational discussion for me as an homeowner with very limited knowledge of the subject. Ryan was patient and is truly an expert. He also provided additional advice on other ground water issues and recommendations for us as homeowners to try, outside the crawl space, in order to save us money. His crew was extraordinarily hard working and diligent, personable and friendly. They did a great job in every detail relative to trench digging, gravel, wrapping, wall insulation, sump pump, dehumidifier, and drainage. Very well done and much appreciated professionalism and expertise. Very impressed with the coordinated team work demonstrated by the whole crew, Damian (foreman), Mac, and David. Very impressive young men. My wife wanted to adopt them and Ryan upon completion of the project, which was done in grueling heat, humidity, and wet conditions. Job well done. Great company.

"We found Cantey Foundations to be the solution to our sagging floors and cracking walls - even after speaking with some of the other popular alternatives. Our team, consisting of Dallas, Corey, David, Dallas and Alex((2 Dallases),were professional, knowledgeable, polite and efficient. Not only did we see a definite change in the sloping floors, but the cracks closed up and doors stopped sticking. When the crew was done, they cleaned up everything. Although it is only a week since the work, we do not have any concerns because of Cantey's warranty, which guarantees the work for 25 years. We were able to put off other recommended work for a later date, and plan to take advantage of that when our pocketbook allows. I will have no problem calling them back."

This is just one of the foundation cracks we found on this foundation. It's what we call a stair-step crack.

"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.

"He was awesome.  He called back, but he was working in Reed field, North Carolina and he could not get to us for a couple of days.  By the time, he got to us we had already gotten the other estimates, and we were pleased with him.  Hampton guy was great.  He was really quick to get back to us, but he had other projects that he had already lined up.  The experience was very satisfactory.  He was very courteous, and prompt.  He was very honest in saying that he cannot get to us, and if we needed to have this work done now, then we need to have to get somebody else.  I appreciated that."

Basement Waterproofing questions, answered by experts

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

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.

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.
