"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."

"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."

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:
Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites
You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home.
However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
From average costs to expert advice, get all the answers you need to get your job done.
