Family owned business since 1982 and 2016 Angie's List Super Service Award winner. All long term employees, no salesman and the two owners are on every job. We do not sub-contract unless it is a field of expertise outside of our field of business. We do offer financing and payment plans.

"The entire experience, from start to finish, was a pleasure, which we were not expecting. From the time Curt came out to take a look at our issue, from the time the team was wrapping up the work, everyone was extremely professional and friendly. We always heard from Curt when he said we would hear from him, and the team on-site was a hard-working group of professionals. The quote from Real Dry was about 3k less than competitors. There were no high-pressure sales tactics, and no surprise add-ons to the quote. And the work they performed is top notch! They did a fantastic job and they will be my go-to company for any services they offer. We are very happy with the entire experience!"

Basement Waterproofing questions, answered by experts

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

Water damage always poses the risk of mold, but if you act quickly enough (within the first 24 hours), you may be able to avoid mold growth resulting from water damage. Clean up the water quickly and thoroughly dry the area. If the issue is more extensive or you didn’t act quickly enough, it’s always safer to assume mold has grown and hire a mold inspector to examine the area.

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.

Finishing an unfinished basement adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.
