"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."

"Everyone was very professional and courteous. Since they were both waterproofing (installing a sump pump system) and finishing the basement there were two different crews but each one was knowledgeable and took care and time to show me every step they were making. There were a few times where communication from the head office was a little lacking but the team members themselves were great. I would highly recommend their services even though the price tag is quite high."

"We interviewed several waterproofing companies for installing a French Drain. We are in NE Philly where the water table is so bad. We get water in our basement with nearly every major rainstorm. After 2 storms dumped 7" in 3 hours and another that dumped 4" 2 days later, we'd had enough after 13 years. Ryan came out and did an inspection and showed us what our basement needed and what Dry Tech's installation would do. He answered a lot of questions and did great follow up with us, without being pushy on hiring his company. After meeting with other contractors, we gave them the job. The workers were thorough, courteous and professional. They took all the steps needed to cover and protect our things that were in the basement and cleaned up everything afterwards. The job took 2 days. While I can't YET state how great the drain works, I'm actually looking forward to the next big rainstorm"

"The required fix required that outside trenching be done and B-Dry does not do this type of work. The representative was very knowledgeable about the problem and apologized for not being able to solve the issue. Very much appreciated his honesty."

Basement Waterproofing questions, answered by experts

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.
