"They leveled our sagging floors beautifully and installed a drain system with a sump pump to address basement flooding issues. All was done with punctuality, precision, and professionalism. Additionally, the price was very reasonable especially compared to competitors. Highly recommend."

"It took two days to tear out the old insulation under the bottom floor and install encapsulation in the whole crawlspace. Nick and his crew did quality work getting the job completed. They also patched holes in the foundation, hauled off all the old, dirty insulation and torn vapor barrier. All-in-all a very accommodating crew."

"What a great experience! I had no hesitation hiring Josh and Sarah after meeting them and hearing their recommendations for remediation. I thought my problem was in the attic but after a thorough inspection, the issue was clearly in the crawl space. Josh, Sarah and crew were very thorough and efficient and took the time to go the extra mile to assess mid-stream to make additional adjustments. I am so pleased with the finished product. When another contractor compliments your work, that's saying something. Great job guys!"

"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.
