"I was please with the estimator, Boston's knowledge and willingness to walk me through the process and unfamiliar territory of basement waterproofing. He was very knowledgeable and answers so many questions, at the time of the walk through as well as in the days after when I had questions after receiving other bids and trying to compare them. In the end, it was just my low budget that kept me from going with Terra Firma. I thought their system was excellent, and would have worked well with my basement, but I had to opt for a less expensive design."

"Attempted to locate the source of moisture that has led to warping of hard wood flooring. Was unable to do so but did everything within his power - provided a recommendation of someone who may be able to do so. My only second-guessing was that Chanse didn’t have a moisture meter that may have further solved the question."

"Efficient, caring, and clean. The final bill came in under the estimate even though I added some work that wasn't figured into the original job. For the type of work this company and the owner does, I wouldn't think of hiring anyone else in this area. I rated them as a 5 star only because I couldn't go higher."

"I have been using them for 3 years for multiple projects and would not go to somebody else. They also built a cabin in the woods. It was built 10 miles from the road so it was like carrying all the stuff up the path. They also did the garage and remodeling of the house, mostly kitchen and a little bit of plumbing work in the bathroom. I am still using them and I would be using them for the next thing that will be coming up too."

Basement Waterproofing FAQs, answered by experts

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.
