"Francisco has to be the best service contractor of any trade. Very HONEST, responsive and great quality work. We had several other basement waterproof system contractors out, and all were clueless or gave inaccurate information. Francisco's knowledge and expertise was impressive. Now, after several months and heavy rains, the basement remains perfectly dry. We called Francisco back for some minor cosmetic sealing, and he responded perfectly again, on a weekend day. You won't regret calling Francisco"

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.

"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."

"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."

"the fireplaces were cleaned very well and very quickly (the basement fireplace was VERY full).  we received an estimate for other work that needed to be done (see above) and everything was written clearly and concisely, with a specific dollar estimate.  then, they sat down with us and explained every step of the repairs that were needed and why they were needed and how it would fix our issues, including smoke from one fireplace blowing into the basement.
when they came back, they were prompt and so efficient.  they completed the work quickly and cleaned up everything after themselves.  i would definitely use them again!!"

Basement Waterproofing FAQs, answered by experts

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

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.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.
