Sealtech Waterproofing

If you want to have your foundation waterproofing job done the right way, then I recommend that you have Dani and Sealtech Waterproofing take care of the project for you. They are extremely honest, hardworking, skilled and professional. When I had their work inspected by the County Building Department, the inspector termed their quality of work as "outstanding". After waterproofing I also had them backfill the foundation which was also performed to the same high standards. Everything was completed at a cost that was more than fair. I first contacted Sealtech because of the good reviews I had read about them, but now I'm happy to make the same kind of recommendation based on my own personal experience.

I’ve had fantastic experiences with Dani and the Sealtech team. They are incredibly knowledgeable and professional from start to finish. Dani took the time to explain exactly what was causing our drainage issues and provided a clear, fair estimate without any high-pressure sales tactics. The crew worked efficiently, arrived on time, and left the property spotless—you’d hardly know they were even there. It’s hard to find contractors in the Charlotte area with this level of integrity and work ethic. Highly recommend them for anyone needing waterproofing or crawl space work!

SealTech Waterproofing came to my rescue when I discovered I was having an issue with my Crawlspace. Dani, the company owner came out to do an assessment. We decided we needed to have a full encapsulation, French drains installed and downspouts added to my home. Dani walked through each part of the project needs in detail, outlining the benefits, the cost and what was available. He put together a great pricing package. The crew members were professional. They were clean, precise, friendly, and you can tell that they cared about the work that they did. They were very responsive to my questions, help to bring solutions and left my property looking great. If you are looking to have your crawlspace or French drains or gutters repaired, call Dani at SealTech…he and his team are the right people for the job.

We just completed an exterior waterproofing project with Sealtech, and they did an outstanding job. We couldn’t be happier with Dani and his crew. Our issue involved a basement leak that required exterior waterproofing along the foundation wall, and it was one of the most challenging projects I’ve ever seen. Due to the location of the leak, much of the work had to be done by hand. The team carefully excavated along the side of our house and managed to protect and work around our HVAC units without requiring them to be removed and reinstalled. This was important to us because it would have added a lot of cost and we would have been without heat in the house for days. They installed a drain line at the base of the foundation, backfilled with gravel, applied a waterproof membrane and dimple board, and ran underground drain lines to the backyard that also tied into our gutter system. They were extremely careful while trenching in the backyard, finding existing cable lines, irrigation lines, and other utilities without damaging anything. When the job was complete, they thoroughly cleaned the area and made sure we were completely satisfied with the results. Communication with Dani (the owner) was excellent throughout the entire process. Unlike another company we considered, he never tried to upsell us or recommend unnecessary work. We truly appreciate their professionalism and would absolutely call them first for any future waterproofing needs. Highly recommended!

Dani and his team at Sealtech Waterproofing did an excellent job on our property. We had a major issue with large amounts of water running through a drainage pipe into our yard, causing significant erosion. His team installed a French drain with river rock and catch basins, and the problem is now completely resolved. The finished work looks great, the price was extremely reasonable compared to other quotes, and Dani’s knowledge and customer service were outstanding. I highly recommend this company for any water‑drainage issues—they exceeded all our expectations.
