Northwest Poly Services specializes in lifting concrete. We’re here to help our fellow residential, commercial, and municipal neighbors repair their sunken concrete slabs, walkways, and stairs. Our Pacific Northwest climate makes large demands on our soil, often causing our sidewalks, garage floors, and concrete slabs to settle and become uneven. This can lead to trip hazards, or worse, more major problems like drainage and soil erosion. Let us help! By drilling a small hole through your sinking concrete and injecting our poly foam solution, we can lift those problem areas level again. We serve Snohomish, Skagit, Whatcom, Island, and San Juan Counties. Give us a call or send us an email for a Free Estimate. Our service comes with a 25 Year Transferable Warranty and proceeds from every job go right back to the communities we live and work in.
"They raised a sunken cement sidewalk. They were punctual, efficient, explained things well, friendly, cleaned up, and did great work! Beautiful! I highly recommend them!"

"When I was getting bids for our paver project, one of the three bids I got was from Rios Brick Pavers. I asked Mauricio, the owner, why I should hire him. Without hesitation, he responded, “Because of the quality of our work.” He went on to say that his crew is great at what they do, and they have been with him for many years. He told me that there may be some competitors who will offer a lower price, but none will match his quality workmanship. Mauricio and his crew went on to deliver on his promise. We had walkways, a large gravel area, and a brick patio integrated into a beautiful and welcoming space that greatly enhances the usability and the look of our home. We could not be happier with the quality of the work and the finished look of the paver project. Mauricio was excellent on communicating status throughout the project. As there are with any project, there were a couple of unexpected challenges that he let me know about right away. The solutions he developed provided additional proof of the experience of his crew. Finally, it should be noted that his team began the project on schedule and finished a day early. I give Rios Brick Pavers my highest recommendation. Quality work at a fair price. Beautiful result."
