"He tried to see if the water heater could be repaired, but it was too damaged from rust. He replaced it with a new one with a six year warranty. He protected the floor with plastic from possible leaks before he removed it and was careful to clean everything up before he left. He also made sure it was working before he left. He was very nice."

"They didn't end up doing the work. They were really high on what they wanted to do. Other people who looked at the porch said that it was not causing an issue with any water intrusion and that there doesn't seem to be any signs on the posts that this could have been recent, it could have been long ago. So no work was done. It was a front porch that had just the level concrete on one side was dipping just a little bit. I think they were going to pump it up from underneath or something like that to level it out. I would say that their response time and their professionalism of getting the quote to us on a timely manner was good. The quote was high and yet the work was not necessary according to other quotes. They should be honest to say when repairs are necessary and when they are not. The guy who showed up was nice and professional and was on time. There was a decent response time."

"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."

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.
