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"

At Ram Jack West, we treat customers with respect and care. If you notice cracks, damages, or other issues with your foundation, our team is ready to help. We have innovative systems that have been refined over our 40+ years of experience.

"Purchased a 1906 home in North Portland with an uneven foundation that had been patched for 60 years, but needed serious stabilization work. I contacted multiple foundation contractors in the greater-Portland area and Ram Jack was the only team that provided a full worse-case estimate that included everything that I may need to permanently stabilize the home's foundation. Other contractors' estimates were higher, omitted some of the features of Ram Jack's estimate, and involved greater excavation work around the home. While I was collecting estimates, I had multiple contractors check the levels on the house and could see the home was continuing to sink as much as half and inch in some areas within only a few months, so I knew I had to do something soon as the hotter summers are causing significant erosion to the clay soil in north portland. After paying the 50% down payment, I was quickly in touch with multiple project managers and structural engineers who were able to answer my questions as the work plan developed. I work from home and have two cats, so I was a bit worried about the noise and needing to leave at certain times during the work. Ramjack devised a plan of installing 12 helical piers from the basement and 2 outside for a small crawl space area as well as replacing most of the piers in the basement that had water damage. During the excavation and pier installation, I didn't have to leave my house at all, my cats were fine, none of the utilities ever needed to be turned off and none of the neighbors said they heard more than the hum of the generator outside; insane professionalism. The work team kept me informed at every step of the excavation and pier installation and was able to recover an inch of lift with only a few drywall cracks that I patched in a day. I could have gone further, but wanted to avoid any potential damage to the sewer pipes and stay within my budget. During the lifting, I was standing with the lead construction manager who kept me informed of every risk as we lifted the house bit by bit. During the excavation my basement looked insane with mounds of dirt everywhere, but the construction team cleaned everything flawlessly; all I had to do was a quick mop and the basement was good as new again. Overall had a great experience with RamJack; the 20 years in business shows, most everyone I dealt with had been working with them for years; the construction manager had been doing pier installation for 15 years. The work was expensive, but cheaper than the other local contractors, and certainly way cheaper than replacing the entire basement foundation. Ramjack was even able to take a few grand off the intitial worse-case estimate for solutions not needed. Glad I was able to repair my 120 year old home; here's to another 100 years. Big thanks to Pancho and Stephen, as well as the structural engineers and project managers; I'm very happy with the work."
