"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"

He is super easy to work honest he follows up to see if you are satisfied with his work.. I recommend him to everyone."

"Friends who know what our basement looked like before are flabbergasted. The information they send you after you contact them is super educational and everyone was prompt, polite, and professional. Wish we'd done this sooner."

"Very impressed with Darren: his work ethic, thoroughness of the work, cleanliness of the job site when the job was finished. He arrived when he said he would and stopped by when he was done for the day to let me know he was leaving. I certainly would recommend Pacific Waterproofing, LLC."

"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 had a clogged kitchen sink that was backing up into my basement utility sink. They were able to come out same day, they had an advertised deal that seemed almost too good to be true. They were fabulous to talk to on the phone and schedule the visit and consult. After they gave me a definitive price, they grabbed their gear and were able to clear the drain in 15 minutes. The price was amazing, and they helped put my fears to rights. 10/10 would recommend!"

Basement Waterproofing questions, answered by experts

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.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.

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.
