"I was extremely pleased with All Dry. They gave me many options to fix my flooding basement problem without any high pressure sales techniques. The crew did an awesome job and were very courteous. I made a few changes as the install progressed and they handled everything with a smile.
There are a few companies that do the same type work and I have used 2 of them. I would not hesitate to recommend All Dry.

"Technician arrived on time and did the inspection in about 20 minutes. He was courteous and proved a written evaluation of the crawl space including actual moisture level. Fortunately we don't have any problems or need for remediation. If we did need some work to be done, would definitely call Crawl Space Medic again.

"After giving us an estimate in Dec 2014 and constantly following up with us they earned our business. They installed 8 piers and 3 beams under our home and what a difference! Just walking across the floors feels so sturdy. Now that this has been completed we can begin working on our kitchen remodel. Thanks Again!

"Scotty was very prompt in phoning me and was able to come out the next day. He was right on time and very professional. He inspected our shower and recommended we get a bigger fan and purchase a dehumidifier. He told me how to clean the mildew and said since we weren’t showing signs of respiratory problems he didn’t recommend air quality test at this time, but told us how much it would cost ($150.00 less than one phone quote) if we wanted to have it done. We offered to pay him for his time, but he refused stating the inspection is free. Not too many businesses are like this in this day. I would highly recommend HISCO Enviromental to anyone requiring this type of service!"

"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.
