What Slabjack NW does

Slabjack NW, LLC is a family-owned specialty contractor that provides concrete raising, leveling, and void-filling services to residential, commercial, and municipal customers across Western Washington. Founded in 2006 by William J. Freeburg and now managed with his son David J. Freeburg, the company operates primarily in the Puget Sound region from a Lynnwood headquarters, serving 33+ cities including Seattle, Bellevue, Tacoma, Everett, Redmond, and Bellingham. The core customer base is individual homeowners with sunken driveways, sidewalks, garage floors, basement floors, porches, and pool decks, supplemented by property management firms, HOAs, commercial property owners, and Western Washington municipalities seeking sidewalk, warehouse floor, and roadway stabilization.

The company's technical foundation is polyurethane foam injection concrete raising, branded as PolyLevel, using a two-liquid chemical mix that expands after approximately 20 seconds and cures in roughly 30 minutes. Drill holes are 3/8 inch (versus 1 inch for traditional mudjacking), the cured foam weighs approximately 4 pounds per cubic foot and is waterproof, making it lighter than mudjacking slurry and less disruptive to weak subgrade soils. The company also offers FILLFOAM, a proprietary pre-expanded open-cell polyurethane foam for void filling applications beneath slabs, foundations, and utility trenches. Concrete crack repair is offered as a complementary service through a third-party vendor under separate contract.

Commercially, Slabjack NW runs a direct-to-consumer, sales-led model: customers initiate contact via phone or website for a free on-site inspection, estimators provide in-person quotes, and projects are scheduled via online proposal acceptance. Revenue is service-based with unit pricing ranging from $150-$400 per sidewalk panel to $800-$3,000+ for full driveways and garage floors, with commercial projects quoted individually. Standard customers pay within 7 days of completion while corporate accounts net 30. The company is privately held with no external equity financing, holds Washington State Specialty Contractor registration (SLABJN*943L1), and is an MRSC partner eligible for municipal procurement. Since 2006, the company claims to have saved over 62 million pounds of concrete from landfill through restoration rather than replacement.

Regional players

• Acculevel: Foundation repair and concrete lifting company serving the Midwest and South with polyurethane foam injection and piering systems. Comparable in service technology and residential/commercial mix to Slabjack NW, but operating across a multi-state Midwestern footprint rather than a single metro region.
• Thrasher Foundation Repair: Regional foundation repair and concrete lifting operator serving the Midwest with both polyurethane and traditional methods. Comparable business model, technology stack, and customer mix to Slabjack NW, but operating in a different geography with a larger service radius within its region.

Broad incumbents

• Groundworks: Large multi-brand foundation and concrete services platform that owns PolyLevel, Foundation Supportworks, and other regional operators. Competes with Slabjack NW across foundation stabilization, void filling, and slab lifting but at much greater scale, with broader service portfolio and centralized marketing.
• Foundation Supportworks: Dealer network specializing in foundation repair, piering, and related geotechnical stabilization, often working with polyurethane foam for void fill and slab support. Comparable to Slabjack NW in the void-filling and foundation stabilization portion of its offering, though anchored on structural foundation repair rather than surface slab raising.
• Ram Jack Systems: National foundation repair and stabilization network with both commercial and residential offerings. Adjacent rather than direct competitor — overlaps on void filling, soil stabilization, and structural slab support but its core focus is driven-pile foundation underpinning rather than surface concrete raising.

Direct peers

• Concrete Jack: Concrete raising and leveling service provider using both mudjacking and polyurethane foam methods on driveways, sidewalks, and commercial slabs. Closely comparable service catalog and customer type to Slabjack NW, though serving different regional markets.
• PolyLevel (Groundworks): National polyurethane concrete raising brand operated under the Groundworks network, using the same lightweight foam injection method as Slabjack NW's PolyLevel product. Direct technical and service-line overlap, with the key difference being national scale, franchise distribution, and institutional backing that Slabjack NW lacks.
• A-1 Concrete Leveling: One of the oldest and largest concrete leveling companies in North America, operating across dozens of franchise territories with both mudjacking and polyurethane services. Directly comparable to Slabjack NW in service offering, customer type (residential, commercial, municipal), and technology mix, but with substantially greater geographic footprint and brand reach.
