SeaTac's older homes and the concrete around them
SeaTac borders Tukwila and Burien. On our jobs there, it reads as a city of older single-story homes and split-levels on modest lots, with apartment buildings, hotels and small businesses along the busier roads. Many of the houses went up decades ago, and plenty still have the driveway, front walk and steps they were built with.
That shapes the work, because older lots often have tight side yards, low fences and mature trees close to the drive. We plan how the truck and crew will reach the pour without harming your yard or your neighbor's.
Concrete services for SeaTac homes and properties
Older SeaTac driveways that have cracked through or sunk by the garage usually need a new slab and a new base, not another patch.
A back patio gives you a level, easy place to sit on the smaller lots here, and we slope it so water runs away from your house.
Stamped concrete gives a patio or front walk the look of stone or brick, which suits homeowners updating an older SeaTac house without laying pavers.
When a front walk has heaved or broken into a trip hazard, we tear it out, pack a fresh base and pour a walk that sits even underfoot.
A cracked or stained garage floor in an older home can be broken out and repoured, so the slab drains toward the door and holds up to parking.
Colored and textured finishes let you match new concrete to the trim or siding on your house, so a replaced walk or patio looks planned rather than patched.
Where a yard steps down toward the street or a neighbor, a poured retaining wall holds the soil back and gives you a flat area you can use.
We pour interior floors for shops, basements and commercial spaces in SeaTac, with a packed base and a finish chosen for how the room gets used.
Around a SeaTac backyard pool, the deck needs a textured surface for wet feet and a slope that carries splash water away from the pool and house.
Front steps on older homes often settle away from the porch or crack at the edges, and new poured steps give you even risers and a safer climb.
For a new garage, shop or addition on a SeaTac lot, we pour the slab on a dug-out, packed base so the building starts level.
When you're building new or adding on, we form and pour the foundation to the plans, and questions about the design go to your engineer or the city.
Small businesses and apartment buildings here often need a parking lot or pad poured thick and graded to drain, so it carries steady traffic.
Footings carry a deck, porch, wall or shed down to firm ground, and we dig and pour them to the depth and size your plans call for.
If part of an older house has settled, we look at the cause and talk through raising it, and we'll say so when it needs an engineer.
We saw-cut old slabs for a new walk, a drain line or a wider driveway, which leaves a clean edge instead of a broken one.

What we check before a SeaTac job starts
Permit questions here go to the city's Permit Center, at 206-973-4750 or permitcenter@seatacwa.gov. When a job does need a permit, the permit and its inspections set part of the schedule along with our crew. Before you hire anyone, there are two things you can check. Washington requires every construction contractor to register with the Department of Labor & Industries and to be bonded and insured, and a contractor needs a City of SeaTac business license to work in the city, even when it's based somewhere else.
We're licensed and insured, and we come over from Renton for the same driveway, patio and step work we do there. At the estimate I check which office covers your address and go over whether your project may need a permit. The price here moves with the size of the slab, how much old concrete and soil has to come out, how much base the ground needs, how close the truck can get and the finish you choose. The schedule turns on any permit and inspection, and on the curing time, the wait while the new slab hardens enough to use. Your written estimate lays out that scope so you can compare it with any other quote.
Older SeaTac slabs and what wears them down
Most of the cracked, sinking driveways I look at here weren't poured badly so much as poured on a base that was only raked level, so the dirt underneath kept settling and the slab went down with it. Once a slab tips toward the house, water pools against the foundation or runs into the garage, and that's the part of the job I care about most. We dig down to firm subgrade, the soil the slab rests on, pack a solid base and set the slope so water runs away from your house before any concrete arrives.
Rentals, apartment lots and small commercial pads see more cars and foot traffic than a family driveway, so broken edges and worn spots show sooner. For those we thicken the slab where vehicles turn and add rebar, steel bars set inside the concrete that hold it together if it cracks, where the load calls for it.
How a concrete job with us runs in SeaTac
From your first call to the final walk-through, here's what a SeaTac concrete job with us looks like on your side.
Call or send the form
Call (425) 264-4089 or send the form, and I'll set a time to come out that suits you. It helps if you're home for that visit, so you can show me what's bothering you about the old slab.
Walk the site together
I come out myself to measure, look at the ground and where water runs, and ask how you plan to use the space. You get a written estimate that explains the prep, the concrete work and anything we'll ask of you before pour day, and we go over what the city or county may want to see.
Prep, inspect and pour
Our small crew digs out, packs the base, sets the forms and pours, and I check in on the job as it goes. On a permitted job, a city inspector has to approve the work before it's covered, and whoever holds the permit books that inspection, with requests in before 10 p.m. for a next-day visit.
Walk the finished work
We keep the area neat while we work and cover what needs covering. Before we pack up, we walk the finished work with you and go over when you can walk on it and when you can drive on it.
Questions about concrete work in SeaTac
How much does a concrete driveway cost in SeaTac?
I can only give you a fair number after measuring, because the cost rests mostly on how much old concrete and soil has to come out and how much base your ground needs. Stamping, color or a thicker slab for heavier vehicles raise the price, and a plain broom finish, a light texture that gives shoes and tires grip, keeps it lower. If the budget is tight, I'd suggest trimming the finish before the base, because a fancy top on a weak base cracks like any other, and the base can't be fixed later without starting over.
How do I find out if my concrete project in SeaTac needs a permit?
Ask the Permit Center, because the city's own checklists don't settle it for flatwork like driveways, patios and walks. Those checklists cover residential decks, drainage control, new homes or additions, remodels and re-roofs. At the estimate we go over it with you, check with the office that covers your address, and can handle the application or help you with yours.
How long before I can drive on a new concrete driveway?
You can walk on a new driveway well before you can drive on it, because concrete keeps gaining strength for days after the pour while it cures. Driving on it too soon can crack or mark a slab that looks hard but isn't ready yet. We'll give you the walking and driving days for your slab before pour day, so you can plan where to park in the meantime.
What causes concrete driveways to crack, and will my new one crack too?
Concrete shrinks as it cures, so nearly every slab cracks somewhere, and the aim is to decide where. We cut control joints, grooves that give the slab a straight, planned line to crack along, and we cut them on time, because joints cut late or skipped leave cracks wherever the slab chooses. A packed base and a slope away from your house help keep it from sinking and splitting the way many older driveways here have.
What paperwork should a contractor give me before a concrete job in Washington?
For any residential job of $1,000 or more, the state requires the contractor to give you a disclosure statement called the Notice to Customer. The same notice applies to commercial projects from $1,000 to $60,000, which covers many small lots and pads. If a contractor doesn't bring it up, it's worth asking for it.
Can I get money back if a contractor does bad work in Washington?
Yes, since July 1, 2026, eligible homeowners can apply for recovery payments when a construction contractor's work causes them financial loss. The program gives people harmed by a contractor a path to get money back, and the state explains it with its contractor laws and rules. It's worth reading what makes you eligible before you need it.
