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!"

"DONT WASTE YOUR TIME! We were contacted by Avi after using Angi's List. He said he was in the area and could swing by for an estimate. Once here he suggested we get the leak from our skylight fixed immediately. We agreed, signed a contract then paid a deposit. Work was to start the next day. We then get a call, parts won't be in for four days, but crew will load up and be here Monday with the parts. Monday comes around, no crew. I call late morning and am assured crew will be there. They show up with caulk. I call Avi, he explains they don't have the parts, and don't know when they will, he comes down and tarps the leak. He offers to pay for a new skylight if I don't leave a bad review. I tell him just fix the leak as agreed. One week goes by, he texts me they can't fix it and offer to refund me. What a waste of two weeks! At least I got a tarp out of the deal. What roofing company can't fix a leak from a skylight? I have a complete text log from with all the excuses to why they can't do this job for all those future customers to enjoy. It does make for a good laugh at the back pedaling from Avi."

Concrete leveling services FAQs

Mudjacking can be an expensive foundation repair process, but in many cases, it’s well worth the investment. This is especially true if you’re lifting a portion of sunken foundation slab back into place. In that case, mudjacking can help avoid major structural damage and even home collapse by restoring the integrity of your structure with minimally invasive procedures. Mudjacking a concrete patio, walkway, or sidewalk can be worthwhile because it removes tripping hazards and makes your outdoor area more aesthetically appealing.

The average cost of mudjacking is around $5 per square foot of concrete, with most concrete leveling jobs totaling between $3 and $8 per square foot. The typical cost to fix a sinking portion of concrete slab with mudjacking is around $1,100. The price you’ll pay depends on the size of the concrete slab you need to be leveled, the accessibility of the slab, and the type of material your contractor uses beneath the concrete to lift it back into place.

In most cases, no, mudjacking is not possible as a DIY job. Not only do you need specialized equipment to cut into your slab and pump the cementitious material underneath it, but it’s also a challenging process, and the consequences of making mistakes include additional structural damage to your home. It’s possible to rent mudjacking equipment to attempt a DIY repair, but the risk of added property damage usually isn’t worth the money you’ll save on labor, especially if the concrete you’re lifting is a part of your home’s foundation.
