"Fast Estimate , had many estimates from other companies and Waterproofing One was the best price for Us , Joe was very confident and knowledgeable and gave Us good suggestions for our leaking basement, the crew that installed the French drain inside were great, install looks very professional. I figured we’d have a mess to clean up after the install understandably. But wow they did an incredible job cleaning up afterwards. Not a speck, they even spent time cleaning off the driveway and front lawn. We have been through one major rain storm since the install and not a drip of water. So far so good , we are getting an expected 3” in the next 24 hours and it’s a relief to know I don’t have to stress about rain storms anymore!"

"We found Basement Waterproofing Nationwide to be highly ethical and very knowledgeable. A little over a year ago we had BWN perform some basement waterproofing. We were delighted with the work and the options presented to us as well as the speed with which it was done. This summer during the very heavy rains, we had some water seep into the basement so we called for an evaluation. As it turned out, the rebuild contractors (which we had opted to contract with a lower price provider vs. using subs hired by BWN) never communicated to us that the newly installed sump pump required an electrician and that it was not hooked up. This house is inhabited by tenants and we are not in the same state, so it's hard to tell where the communication breakdown occurred. Basement Waterproofing Nationwide's service rep however was extremely professional and helpful in delivering this bad news. He also checked and was able to confirm that the waterproofing was still good. He made a few suggestions like letting us know that he noticed where the drywall had been replaced that the outlet plates were never reinstalled. I also had some questions about the contract and he was very helpful and had the office fax me the pertinent info that same day. Lesson learned for me was that it would probably have been better to let BWN hire the contractors for the rebuild esp when you are out of town and unable to oversee. When there are heavy rains in the area like Baltimore had in July, it might take a few days for them to process the volume of calls especially if the nature of your request is minor. But they do respond. They are extremely professional and they stand behind their work."

Basement Waterproofing questions, answered by experts

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.
