We had two crews working to address the water in our crawlspace. Thanks to David, Derick, Jordan and Sam, along with Wyatt, Tucker, and Quentin! And thanks to Kirsten for coming out initially and explaining the Groundworks approach. Though not new to the Pacific NW, we had recently located to the far NW corner of WA. The proposed work was finished in record time (and they managed to get us in a week before the scheduled work). This is no small patch but a wholesale addressing of the problem. It wasn’t cheap, but the thoroughness of the solution is keeping us comfortable and dry! Thanks Groundworks!

It all started with the Groundworks Crawl Space commercial and Mr. Mike Rowe doing the "Dirty Job". thats when my wife and i decided to call Groundworks. We made an appointment and as promised the Inspector arrived right on time, maybe a little early, but he called first. The Groundworks Inspector Mr. Corey Meyers was the best and most prepared inspector that i have ever met. Corey took time to first ask a series of questions and then got dressed up in his protective gear and adorned his assortment of tools and inspected our 100 yr. old crawl space. The inspection was a success. My wife and I are extremely impressed with Corey and the Groundworks company. Thank you so much.

We have just begun our experience with Groundworks. Corey Meyers the CFI was very knowledgeable about the process and diligent in his assessment of how to solve our wet basement issues. He followed up as promised and has put us at ease with our decision to move forward. I will follow up after the work is completed.
