"The team, led by Trevor, and assisted by Kenny, Terrell and Garrett, worked very well together to accomplish the work we needed done to alleviate water coming into our crawlspace. They were courteous, friendly, professional, and did not hesitate to answer all our questions and explain the process thoroughly. Trevor and team brought other problems to our attention which we have decided to have Mount Valley repair also. Trevor and Shawn helped us get the process going to replace floor joist damaged by water. I would recommend Mount Valley if you have foundation issues that need expert repairs!"

"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

Encapsulation can take the place of crawl space vents since it protects the area from moisture and air all year round. Determining whether you should open or close crawl space vents can be complicated since it often depends on the weather and humidity. Skip this step by investing in crawl space encapsulation whenever possible.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

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.

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.

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.
