"We had our basement waterproofed by Baker's. It's been bone-dry since. We did have one piece of equipment fail within a month of the installation, but it was a third party dehumidifier that was just a dud I guess, no fault of Baker's. I texted the project manager about it on a Sunday. I expected a response the following week. He got back to me within the hour. The equipment was removed and replaced within a couple days. Everything great since. I would highly recommend Baker's, but specifically our project manager Nathan Goddard and the head guy on site Daylan. Can't remember his last name, but he's got a long beard and did a great job. Thanks to both of them and the rest of the guys."

"This is the second time I’ve used Advanced for my basement waterproofing needs and they were again fantastic. Work was done well and it was easy to schedule. They are low pressure so if you have a project and just need to get an opinion, reach out to them. Chris is great and very attentive and helpful. Both of my waterproofing jobs still cost less the the initial job from one of the big companies, so I was really pleased with their work and price. They did a nice job cleaning up (but concrete dust gets everywhere so I still have work to do). Highly recommend!!!! I also live in a township with strict permit codes and they knew to check and help with that process (the other company did not)."

We take great pride in our experience, expertise, quality and customer service that we provide to meet the consumer's needs. It is our mission to provide excellent workmanship and complete customer satisfaction from start to completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Our reputation is based on service, safety and quality, regardless of how large or small the job.

"We were referred to Bill by someone working on our house, and we’re so glad we reached out. He responded immediately—which is rare these days—and provided a clear, reasonable estimate. We agreed to move forward that same day. The waterproofing work was excellent. Bill’s crew was professional, friendly, and happy to answer any questions we had throughout the process. Their concrete work was top-notch, and they left the space clean and tidy when the job was done. They also took the time to walk us through everything they had completed, making sure we understood each step. It’s been a month since the work was finished, and we’ve already had a couple of major rainstorms—including one with rainfall hitting 3 inches per hour. In the past, that kind of weather would’ve guaranteed a wet basement. But now? Not a single drop. We couldn’t be happier with the results. I can’t recommend them any higher. 5-stars+. "

"G&J was referred to me by another contractor I had doing my windows. My basement walls were very bad caving in. They came out and got on the job quick.

Basement Waterproofing questions, answered by experts

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

While it’s possible to live in a damp basement, it’s usually not healthy to do so. Damp air affects your breathing, and it also promotes mold growth and pest infestation that can make living in a damp basement dangerous. You should plan to resolve any moisture issues and set up preventative measures before using your basement as a living space.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.
