"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"I was impressed with his knowledge and professionalism. He installed a French drain system with a vapor barrier on the walls. He prepped the area to protect our belongings, made sure everything was cleaned up after the end of each day, and provided exceptional service and quality. I would highly recommend him!"

"We hired Leal Restoration to clean up water damage on three floors of our house. They came early on a Saturday morning, worked all weekend and finished the job on Monday. This included drying out the area, removing debris, and replacing a ceiling. The work was done efficiently and carefully. Leal turned a disaster area into a clean and back to normal living space in 3 days. Amazing!"

"Matt came to us with a great cost estimate and was very honest and up front about the pricing. He explained all of the options we had and budgeted us for a certain dollar amount per project so we could adjust it as necessary. He didn't mind when I did my own "independent research" and came back to him with tile questions, paint questions, opinions on 10-lit vs 15-lite doors, and helped us fit the projects into our budgets. His crew as professional and neat, and they even took time out to educate my about the process and what they were doing each day. I learned a lot and we now have a wonderful shower and matching tiled tub, a beautiful open air basement room which was once two, and french doors to keep our heating costs down for the rest of the winter! We only wish we had put those doors in sooner! This is a local, family-run business, and Matt deals with local vendors and manufacturers. He made crucial decisions to change vendors when the original ones could not meet the timelines, and we appreciated that a lot. We are going to use him again for some outdoor porch and deck projects this summer."

Basement Waterproofing questions, answered by experts

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.
