"Joe and his team were the first to respond after the Milwaukee floods happened in August 2025. Him and his team went above and beyond to clear out all of the debris in the basement, fully cleaned the basement, and applied mold remediation to the wooden beams. They also fully rebuilt our stairs and removed and replaced our egress window. Thank you so much Joe and team!"

Everdry is the Nations leader in basement waterproofing with 100,000 satisfied customers! We help you create dry usable space.

"We had a small leak that only happened in severe rainstorms. Instead of diagnosing this problem the salesperson wa ted to sell us their complete system. They painted a picture of a poorly constructed basement with many problems. We resisted but finally agreed this was s mistake, because the only problem found after tearing up our basement was a dead sump pump and maybe extra weep holes could have been put in the crock. The original basement drainage system was correctly installed to code. Now our perfect basement floor has permanent scars and we are still fighting the concrete dust leftover from the project. The workers also damaged our vinyl siding and stained it with some type of solvent when cleaning areas that were marred during work. They are probably solve severe basement problems, but we were definitely “oversold”. We made a regrettable error in trusting their expertise."

"⭐️⭐️⭐️⭐️⭐️ Absolutely Stunning Refinish – Highly Recommend! I couldn't be happier with the way our hardwood floors turned out! We had some old, torn-up floors that honestly looked like they were beyond saving—but the transformation is unbelievable. After the refinishing, they look like brand new floors, absolutely gorgeous, with a smooth, rich finish that completely elevates the look of our home. Not only was the quality of the work exceptional, but the price was also more than fair—especially considering the results. On top of that, they were incredibly professional: they showed up 15 minutes early, ready to work, and clearly take pride in what they do. It’s rare to find that kind of reliability and craftsmanship these days. If you're thinking about getting your hardwood floors redone, do it—and call these folks. I can't recommend them enough!"
