"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."

"Every phase of the basement waterproofing project was first-rate. Through sketches, the inspector/technician took the time to explain how a sub-floor pressure relief system works. In a knowledgeable and professional manner, he designed the system for our basement and presented a detailed project proposal with drawings. An affordable cost estimate was reached. Also, financing guidance was given to obtain a deferred interest loan. Three days later, the construction crew arrived to begin installation of the system. They were attentive to specific concerns and answered all questions completely and politely. Through discipline and hard work, they completed the job in two days, one day ahead of schedule. Upon completion, including a thorough clean-up, a tour was given of the newly installed system. Dry Tech Waterproofing Systems is a high quality and efficient company that I will highly recommend to family, friends, neighbors, and others."

"I am very happy with the work that Bakers Waterproofing did for my basement! They were quick, efficient, and took care doing a great job. Lukas Selleck, Jason Shaeffer, and Dalton Bardole were virtuous and professional. I would highly recommend them to anyone that are in need of waterproofing."

Basement Waterproofing questions, answered by experts

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Make sure you're calling in the right expert to help repair and/or clean your crawl space. A serious issue may require multiple experts that include a local mold remediation pro, an HVAC pro, a foundation pro, and a plumber. You should also consider using a nearby junk removal service to avoid handling debris that could be covered in mold, fungi, rot, or asbestos.

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
