Entry Porch Re-Leveling and Raising in the seattle area
In Seattle and Western Washington, settling of porches is common due to the effects of high rain totals and water. Settled and sunken porch slabs and steps are both dangerous and unsightly, and invite nesting and burrowing from insects, and small animals. 1-866-SLABJACK provides concrete repair, leveling and raising services for areas like porches and patios that may become sunken, cracked and unlevel over time.  Slabjacking brings your porch back to normal quickly and easily without expensive replacement. It is an effective, eco friendly and affordable alternative to replacing your entire porch area, and can often be done in as little as a day.  Contact us today to learn more about our concrete raising services for porches and other areas, and to get a free estimate. We serve the Puget Sound from Tacoma to Everett, Puyallup to Redmond, Bellevue to Lynnwood and beyond.
Why a Sunken Porch Is More Urgent Than It Looks
Your front porch and entry steps are the most trafficked transition point on your property — and the one where an uneven surface does the most damage. A slab that has dropped even an inch creates a genuine fall hazard at the point where visitors arrive, deliveries are made, and family members come and go daily, often carrying bags, children, or groceries. For older adults or anyone with mobility considerations, a tilted or stepped-down porch surface is a serious injury risk.
Beyond safety, a settling porch creates practical problems that compound over time. As the slab pulls away from the foundation, it opens a gap that invites moisture infiltration, insect nesting, and small animals burrowing beneath the concrete — all of which accelerate further erosion of the supporting soil. Water that collects in the gap or drains toward the house rather than away from it can work its way into the foundation wall or crawl space. The longer a settled porch goes unaddressed, the larger those voids grow and the more material needs to be displaced to correct the problem.
Slabjacking addresses all of this at once. The polyurethane foam fills the void beneath the slab, eliminating the shelter and moisture pathway that attracts pests, while simultaneously lifting the concrete back to its original height and restoring proper drainage away from the structure. Most porch projects are completed in just a few hours, with no disruption to the surrounding landscaping, and the work area is clean and usable the same day.
Porch Slabjacking: Common Questions
Can you lift a porch that is attached to the house foundation? Yes — this is the norm for most porch slabs. We take care to lift gradually and monitor the slab's relationship to the foundation wall throughout the process. The goal is to restore the original gap-free connection without putting stress on the foundation.
What if my porch has brick or tile over the concrete? Surface materials don't prevent slabjacking, but significant settling can cause some tile grout or brick mortar joints to crack as the slab moves. Our crew at 1-866-SLABJACK discusses this during the estimate so you have a realistic picture of what to expect before and after the lift.
Will you disturb my landscaping or flower beds around the porch? Our equipment connects to small drilled holes in the slab itself — no excavation around the perimeter is required. Plantings, mulch, and edging immediately adjacent to the porch are typically undisturbed.
How long does a porch lifting job take? Most residential porch projects are completed in one to three hours. Entry walks and steps attached to the porch can often be addressed in the same visit.
Is it worth fixing a porch on a home I'm planning to sell? Almost always yes. A visibly settled or cracked front porch is one of the first things a buyer — or their home inspector — notices, and it can raise questions about deferred maintenance throughout the property. A same-day fix at a fraction of replacement cost is one of the better pre-sale investments available for exterior concrete.
