"I was glad John's Waterproofing was recommended to me to resolve the serious water problem in my large crawl space. With Jake's Design and Jeremy's remarkable crew, who were able to efficiently perform the many tasks needed to fix the problem, I now have a dry, clean and healthier crawl space under my home. Thanks to John's superb 5 star Company! Virginia Rossman"

"Overall the Crawlspace Crew did some great work for our basement area. The initial phone call was very informative, then they came on-site for a walk-thru and provided an itemized estimate we could understand. We expressed that budget was a concern and only elected to do some of the work, they were supportive of this and we were scheduled in within a week. The work was completed in a timely and thorough manner and we are very satisfied. Shout out to Dillon, for working within our budget, and being flexible on the specifics, I would definitely recommend this company/service to a friend or anyone in need."

"I contacted Foundations First NorthWest and a couple of other contractors when an inspection revealed some foundation settling and crawl space damage. I chose Foundations First to make the repairs because they included more work, and at a lower price, than their competitors. I can't say enough about how professional everyone at Foundations First NorthWest was, from the first meeting with the sales rep to the constant communication with office staff throughout the project. Every step was completed without a hitch -- getting permits, engineering, the repair work and county inspections. The work crews worked quickly and efficiently on both the installation of stabilizing foundation piers, and also on the crawl space repairs. And they left the work areas in a very clean condition. I highly recommend Foundations First!"

"Upfront Construction replaced the insulation and vapor barrier in our crawl space. They were really great to work with from the initial estimate to completion. We were able to get them scheduled quickly and they worked with us on the costs. The crew that did the work was friendly, kept us informed of additional issues, and cleaned everything up well. Would definitely recommend!"

Basement Waterproofing questions, answered by experts

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, many repair services include reapplying waterproofing and UV-resistant coatings.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

You don’t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It’s ideal for homes in humid areas.

In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.
