"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."

"From the first visit to my home from Sean for an estimate, to the crew that arrived to do the project I was impressed. Everyone was extremely professional. The crew arrived on time, the crew leader introduced me to the rest of the crew and explained how they would proceed with the project. They protected the work spaces with plastic from my garage to the crawl space opening in side my closet. They went to work and kept me informed about the progress. The whole crew worked very efficiently and got the project done in one day. They left work area spotless when they were done. I would highly recommend this company for any waterproofing project!!"

"Andrew and his Crew from Roseburg were wonderful. They were able to get into our crawl space and did an amazing job clearing it out, installing drainage, a layer of plastic and sump pump. They left the area so much cleaner than it was when they arrived and they explained everything to us clearly so we would know what to do. We recommend them highly and it was a pleasure to meet them."

"Their bid was very competitive, and they did a wonderful job on our installation. We are really enjoying the new system, and it is very energy efficient compared to our older furnace. They were also really helpful with informing us of the available rebates and tax credits.

"B2 construction came out and did a slab for my 2 stall barn 24 feet x 36 feet. Guys were knowledgeable showed up on time when they said they were going to show up and completed the job in a timely fashion. When my barn builder came out to erect my steel barn everything worked out perfectly. Thanks Troy"

Basement Waterproofing FAQs, answered by experts

Access to commercial-grade products and equipment, ensuring thorough coverage and long-lasting protection.

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

Crawl spaces are the more desirable option overall because they provide additional space for storage and utilities, but they are more expensive to install and maintain. Slab foundations are considered a better option in warmer climates where the depth of the frost line isn’t an issue because they’re more affordable, but crawl spaces are better in areas where the frost line is deep or where flooding can be an issue.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
