"Groundworks were contracted to encapsulate the crawl space, with a dehumidifier, intellijacks & sump pump. The inspector showed us pictures & videos of what the work would look like on completion, & explained how each solution would be installed. They tried to charge me more for vent covers until I showed them the contract covering this part. The foreman told me there was a reset button for the sump pump to be installed on an exterior wall, but they did not install it, instead said they would put in a service order. I haven’t heard anything about this issue yet. When they installed the moister barrier, they excluded the cement pads I was told it cost extra to have them covered. When I signed the contract, I was never told there would be extra charges for vent covers or cement pads to be covered. The contract I signed covered a complete encapsulation, but this is not what I got. This is a bait & switch. I would not recommend Groundworks."

"Boyd from Center Construction was very easy to communicate and work with through the entire process and kept me informed from start to finish.

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!"

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.
