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!"

"It is a huge shock to realize that one's home is in such danger with a serious foundation issue that will be very costly. But I have to admit that from the very start Groundworks was awesomely professional and impressive. The evaluation process was ultra thorough. Then the actual workers were beyond amazing. The communicated fabulously with me daily to keep me in the loop. What impressed me the most was how very hard these men worked non-stop during the days, often staying longer than five o'clock to finish the day's job. They were careful with my home and property and cleaned up after themselves. It is quite a relief that in this day and age one can trust and witness such a great company with professionals that have such a phenomenal work ethic."

"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."

Sustainability is at the heart of everything we do. As a steward of our outdoor environment we understand the important role we play. We ensure our work minimizes maintenance, water usage, material transportation, and waste. These principals guide all of our practices to ensure that the air, water, and soils are protected and enhanced. Our firm was founded years ago by Ryan Sarvis to create a turn-key landscaping company that could deliver the highest quality spaces with excellent communication and service to our clients. Ryan has an unrelenting love and passion for landscaping as a 3rd generation landscaper. His devotion to excellence in all areas of the client experience reverberates through all levels of our team. Our founding principles endure today and are at the heart of our operations. We use our in-house carpenters, stone masons, lighting/irrigation tech, and other landscaping craftsmen to ensure the best quality work that is implemented in a timely manner. By avoiding multiple subcontractors, we seamlessly complete projects that require multiple disciplines or facets without delays. Our craftsmen have been trained in the "Green Spaces Way". These sets of standards allow us to stand confidently behind our work with an industry best five-year warranty. Our multiple awards from 425 magazine, Angie's List, Houzz, and local industry groups are testaments to our diligence for the highest quality work and client satisfaction. Our reviews from various sites speak to the service that you should expect when investing in your home's outdoor space. Please contact our design team to learn all about the potential your outdoor space holds.
"The work they did is top notch, I love our patio and couldn't be happier with what they've done with the space. They did a lot of work for us over two months to build a patio and beautiful back yard. We love it. That said, our home is a 70+ year old house in Magnolia with concrete pipes. A year or so after they did the work we had a backup. After the plumbers came out they found that a section of the piping had been crushed by a large rock that had been set while they were regrading the area. The repairs were ~15k all said and done then. I contacted Ryan and he looked into their insurance covering it and they weren't going to do it out of pocket. I value my time more than money and I let it go, and Ryan had some guys come out and fix the area that had to be torn up for free, least they can do. Well after they were done the plumbers spotted another crushed section that lined up and should be 'okay'. Fast forward a year, it wasn't we had another backup. They cleared it and we just had it fixed with another 5k bill. Ryan had said they wouldn't do it for free but 'hours and material'. They didn't give me a quote I shrugged and assumed it would be a mornings worth of work. They came out and spent two days, and they just handed me a bill for another $3200, to clean up after damage they caused and I'm paying for."
