We discovered standing water in the Crawl Space of our (new to us) house in May 2025. We solicited 6 proposals from both local and National waterproofing companies. The lowest cost proposal was from MER Waterproofing. The highest cost proposal was 2.5 times more than MER! Ignoring the prices, we carefully reviewed the proposals. The MER proposal and reviews were the best by far. So we selected MER. We worked with Mike (owner) and Andreas (work foreman) throughout the work. Andreas was with us during 100% of the work. Mike visited the site and communicated with us via phone. In addition, we had the pleasure of working with Junior, Andreas son. An internal perimeter drain was installed along with a single sump basin, a primary pump and a battery backup pump. While completing this work, a crack in the foundation (non structural) was identified by Andreas as an area of water infiltration into our crawl space. They immediately address the issue and repaired the crack with great care. Andreas also identified a support joist that needed support. They poured a concrete support and installed a metal support strut. They also install some 12 x 2 wood joists to further support a side joist. The joist issued was caused by many years of super high humidity. MER finished off the work by encapsulating the crawl space with 20 mil reinforced plastic. Finally, MER installed the dehumidifier I had previously purchased. When I turned on the dehumidifier the humidity was a staggering 86%. Just seven days later, the humidity was reduced to the target 50%! MER Then returned to spray all the wood with an antimicrobial treatment to kill the remaining mold. I cannot say enough good things about MER, Mike, Andreas, Junior and the whole crew. Without doubt, the very best company and group of people we have ever worked with. If you have any basement or crawl space humidity, moisture or water issues, I thoroughly recommend MER Waterproofing, their owner and ALL their team. They are competent, thorough, excellent value and very pleasant to work with!!

Michael and the MER team did a high quality work to ensure they found and fixed the problem in my future home. In the quote, they gave a detailed list of the steps they would perform and the cost. Each of his team members (from guys that dug the soil, inside workers, mason and dry wall guys) were courteous and kept their areas neat. I think they did a bit more work than expect, but still honored their quote. I'd hire again!
