"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!"

"I reached out to this company for a sump pump upgrade and a cracked wall repair. The technician who did my install was very polite and informative. We've had several big storms since my installation was done and I'm happy to say my basement has remained totally dry. I'm very glad I chose this company, I would recommend them to anyone in need of help with their basement!"

"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."

"Scott Graham and his crew were extremely easy to work with. The work crew was courteous to me and to each other - very professional. Everyone on the crew got along. They were neat - the spaces where they worked were cleaner when they left than before they started. Most important to all, the drains and pumps they installed solved my wet basement problem. I highly recommend AWS."

"They responded quickly and had someone out to inspect my basement quickly and at a convenient time. They inspected my basement and recommended an $8,000 treatment. Everything they said made sense and the materials and methods they specified seemed appropriate. That was more than I wanted to spend, so I decided to try a DIY fix first."

"We had numerous issues with water in our basement in the 5 years we owned our home, it was not an easy fix and we received numerous ideas and quotes. The rep from Worthington came out and was amazing, did not try and up sell us, and identified and fixed every problem. Worthington was not the cheapest firm we spoke with but would you really want the guy with the lowest price for a job like this? We would recommend this company emphatically."

"The service I received from Martin's Home Improvement was outstanding! I contacted Martin several weeks ago, he got right back to me and was very flexible with my estimate date/time even thought I had to change it due to shift-work. The estimate was sent to me that night, and Martin was easily able to be contacted with my questions and changes. I was able to schedule the job within the week, it took about 2.5 days from start until finish. Martin and Rob were there promptly at 730am start day. Rob is an employee of Martin's and his work was phenomenal. Rob worked the first two days from 730am to 5pm or so. The quality of the work was worth every penny. Rob was very professional and courteous. Everything was cleaned and vacuumed everyday, and unless you looked into the bedroom you wouldn't know I had a contractor working in my home. Overall I am glad I hired Martin and his company and will again for future projects. They took my old bedroom and turned it into something amazing, I didn't think it could look so nice for the house being 98 years old. If you want your money's worth hire these guys.

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Wilmington, DE

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
