Groundworks specializes in helping homeowners with their residential and commercial foundation repair, basement waterproofing and wall repair, and concrete repair needs. Our top priority is providing high-quality home repair solutions and personalized service across the Seattle area. With fully trained technicians, industry-leading products, and nationally backed warranties, Groundworks is here to restore your foundation.

"From consultation to completion the team at Groundworks handled our foundation repair with care and professionalism. Matthew came to the house and stayed to answer every question and explain every detail. He took the time to complete a bid while onsite and walk us through the process. (BTW their permitting department and financing through GreenSky really helped!) When the work started the first team of Alex, Iuni and Luis, were exceptional (they pier leveled the footing). We got texts the moment they arrived at the property and they got right to work, completing their part right on time. They worked as quietly as possible and kept us informed of the progress. The second team for foam leveling our slab and led by Daniel, got it all done in part of a day. They were also courteous and even helped move furniture. When the work of both teams was finished Alex, the foreman, walked us through an inspection and answered all our questions. Finally, Matthew circled back at the end and made sure"

"I was stressed to the max thinking the home I just purchased had a foundation issue after being told so many things from different companies I turned to Angi’s list and I had totally forgot about my appointment with Rainpros Joel ended up doing the inspection and literally saving me from a stress stroke. He was patient and explained everything as clear as he could over the phone. I have a busy life so it’s not easy to work with me and Joel did just that.

I am very reasonable and open to discuss prices. I guarantee you will be happy with the price we can agree on for quality hard work. We offer free on-site estimates. Our goal is to keep an ongoing relationship with each client and maintain positive communication with the upmost respect. Which is one of the reason's we decided to add "Family" to our company name. We hope to hear from you soon !

"Referrals are everything in this business and I must thank the man who referred Thalia to me. Thalia is on top of things like nobody else. When the team comes though it's like they can read my mind and then some. Every time they do a job on our property, it's finished better than I wanted it and I'm pretty particular about what I want. In fact, I just asked for an estimate on storm damage to my fence. Even though I hired them as landscapers, they are so fastidious that I had to see if they would be willing to do other things for the house. But back to the initial landscaping, my backyard was transformed from a spacious but uneven, boring mess into a magical, balanced space I'd be perfectly happy to have a wedding at. Just fantastic and the quote would've still been reasonable for a job 25% smaller than what they did for me. And they just did the fall cleanup too. if a yard could have that new car smell, mine would have it still. Sincerely, Kristen and family. Briercrest neighborhood."
