          Why Choose Moisture Loc

          Nothing cookie-cutter. Never a franchise.

          • Family-owned and run since 1988. Moisture Loc has served local homeowners and builders for nearly 40 years. When you work in the same community for that long, you get to know it from the ground up. That’s why there isn’t a crawl space or basement issue we can’t solve.
          • We do it right, or not at all. That means finding the real problem, fixing it the right way, and standing behind the work and warranty. It also means pulling the required permits that others skip. Every job gets its own right solution, done to the standard your home deserves, and we demand.
          • You can breathe easier. When 40% of the air you breathe at home comes from your crawl space, you want to know it’s clean. Our encapsulation and waterproofing solutions keep humidity, mold, and wood rot out and a sense of security in. Plus, our foundation and structural solutions preserve the integrity and value of your home while delivering the peace of mind every homeowner wants.
          • This means more to us. We’re rooted here, not spread across states or managed by investors. With one office and one team, the work stays close and personal. Every job means more when you live in the community you serve. We don’t answer to anybody but our customers, the way it should be.

          After purchasing my home, I started noticing cracks in the drywall, just a few months later. After finding out the house had structural issues, I interviewed several companies and decided to go with moisture lock. If your dealing with structural issues, I highly recommend Moisture lock for their expertise and customer service. Carlos, James and Scott were excellent. I am very pleased with my experience and the work they did to my home.

          Moisture Loc has amazing customer service! Very professional, upfront, and proficient! Had them out for a French drain and they did not do me wrong. I would definitely recommend Moisture Loc for your waterproofing needs!

          I have nothing but good things to say about Moisture Loc. I was referred to them by a friend/neighbor, and they did not disappoint. Carlos was thorough in his initial inspection and project recommendations. There were no surprises. I felt like Carlos was honest when he gave us a quote for the work, and that was very important to me. James came with his crew to actually perform the work, and he was equally as outstanding. The work was completely efficiently and properly, and all projects passed Mecklenburg County inspection the first time around. I couldn't be more pleased and highly recommend this company!

          These guys did a great job! We had a moisture issue under the house which was messing up our hardwood floors. I had 2 other companies out and then spoke with my neighbor, who is a contractor. He highly recommended Moisture Loc. They didn't try and sell me on things that were not needed and came in less than the other 2 companies. Their work crew was on time and respectful and pleasant. The job is complete and I'm impressed. Highly recommend!

          Got 4 local quotes for encapsulating the crawl space of our home. This was a no-brainer, Moisture Loc was heads and tails above all others. Dan Richert was extremely professional, clear and to the point, no up sale, and answered all questions. Everyone involved including Rich Goldman and Brandon Cook were also extremely professional, knowledgeable, and very responsive. Everything was on time. And thanks Ryan (office person) for being there and answering the phone! (seems to be a lost art these days). Highly recommend these folks!

          If it’s anything crawlspace related, this is your first and only call. Highly recommended.

          I am a realtor working on behalf of my buyer client to source quotes for repairs. Carlos has been extremely responsive and knowledgeable about his scope of work. I appreciate his honesty in not trying to upsell me on a sump pump because I recieved quotes from multiple crawlspace companies and called to inquire further about this. He was transparent from the beginning and explained why it was not necessary for this particular property, even before I had the chance to ask him. Thank you for your efforts to earn my business. I appreciate you putting the customers needs before your own pocket and look forward to doing continued business with you!

          Had a great experience with Moisture Lock. They installed Helical Piers and re-encapsulated my crawlspace. Jerry was an absolute powerhouse for installing the piers. His knowledge and skills are off the chart. The crawlspace work was great as well - Moisture Lock came in a fixed a botched job that was done by Carolina Crawlspace Pros who are now out of business. Everything is in good order now and these guys did a really great job.

          Earlier this year I heard those words that no one wants to hear about their 7 year old house. “Your stairs are sinking “ I noticed the cracks but believed it was normal settling. Joe with Mint Engineers came out and introduced me to some unfamiliar words. Helical Piers and Angle Irons. In hunting for just the right company to help I chose Moisture Loc. Dan was always available to answer all my questions and REPEATED phone calls. Jerry did an amazing job placing the piers and worked extremely hard to make them as invisible as possible, letting me know he was treated my house as he would his own. Next Jeremy who was the brick mason arrived for tuck-pointing mortar and crack repair. A true artist. Even though I knew exactly where the cracks were I could barely find them. Moisture Loc and their crew were truly amazing. Those stairs will outlive me. I couldn’t be happier with the completed project. Thanks to all for your hard work.

          (Update: September 9, 2025) Our updated French drains and gravity drain have been installed by another reputable, hard working team from Moisture Loc. They were very professional, careful to listen to our concerns on our drain field and underground cables, arriving on time, getting the work completed in a timely fashion, making sure that the worksite was cleaned up before they left. Work quality was inspected by James, the supervisor, who is VERY knowledgeable and professional. Another outstanding job completed by Moisture Loc. We couldn’t be happier! Our neighbors are impressed as well. ( January 2025) Do your research, if you will, but start at Moisture Loc because you will not have to go any further. Moisture Loc is a fabulous company that is made up of people who are conscientious, skilled, hard-working, communicative, and take pride in their work. It is smaller than some, which is what we were looking for, feeling that the work quality would be better than with a larger company. They follow through with their commitments and their schedule is like clockwork. The cost of the work we had done was itemized and clear from the very beginning as well as reasonable. There were no hidden costs. We have recommended Moisture Loc to two of our friends and would recommend them to anyone that asked. Both friends have gone with encapsulation; one job in progress, one completed. Both are exceptionally happy with the company. Even the county inspector commented on the exceedingly high-quality of the work done at our house. Our initial contact was Walt, who gave a very detailed diagram with written explanations of the foundation repair that we needed. (We had his recommendations, checked by a building contractor friend of ours, who was in total agreement with him). James was our inspector for the entire project. As promised he was there at both the beginning and after the work had been completed to make sure things had been done correctly. Marlon was the crew foreman who oversaw the work as it was being done. All three men were accessible, extremely professional, and proficient in their areas of expertise.. There were different crews that specialized in the various aspects of the work being done. Everyone was friendly, professional, hard-working, and efficient.. Our floors no longer squeak and sag after the piers were installed, the rooms no longer smell like mold, the house is much warmer (cooler in the warm months) with the new insulation, and the moisture barrier is doing its job of keeping out any dampness. The team left the yard in excellent shape as well. We feel like we have a brand new house! We are now (August 2025) adding an upgrade to our system, and we are once again using Moisture Loc because we trust them and the work that they do. Carlos was our initial contact this time. He is professional, not at all high pressure, and very thorough. He was clear about the issues that he was addressing as we explored different options and possibilities. He was open to hearing suggestions, and making sure that the best plan was put forward to meet our needs. Moisture Loc has 0 complaints with the Better Business Bureau. The number of complaints is the number to look at. It has an A+ rating. (Many companies have a A+ rating but with many complaints.) They have been in their family business operations for 37 years. It is an amazing company! Moisture Loc is everything a business should be . . .and more.
