Older homes and busy lots across SeaTac
SeaTac mixes single-family houses on long-settled streets with apartment buildings and businesses that carry a lot of paved parking, so the calls we take here range from one cracked front walk to a whole worn-out lot. We're a concrete contractor based nearby in Kent, and we do the same work in Burien and Lakeland South.
Many of the houses here have driveways, patios and steps that were poured decades ago, and by now plenty of them have cracked, dropped at one end or tipped back toward the house. That's why the price and the schedule on most SeaTac jobs turn on what's underneath: how much old concrete comes out, how much base we rebuild, whether the work needs a city permit and inspection, and how long the new slab has to cure. Your written estimate lists each of those for your own job.
Our services in SeaTac, WA
- Concrete driveway building
Older SeaTac driveways often crack or sink where the base gave way. We break out the old slab, rebuild the base and pour a new one that sheds water.
- Concrete steps construction
Front steps on older houses often settle and pull away from the porch. We tear them out and form new concrete steps with even rises, set on firm ground.
- Concrete patio construction
Many backyards in the city have a cracked patio that tips toward the back door and holds puddles. We pour a new one that drains away from the house.
- Concrete sidewalk building
Front walks here often heave over roots and leave edges you trip on. We cut out the raised sections, clear the roots and pour new panels that sit flush.
- Concrete parking lot building
Apartment and commercial lots take steady car and truck traffic that wears paving out. We can rebuild in sections so part of your lot stays open.
- Concrete cutting
On older lots, often only one panel of a driveway or walk has failed. We saw-cut that section out so the new pour meets the old along a straight edge.
What older SeaTac lots ask of concrete
When an old slab has sunk or cracked badly, the cause is usually under it, either dirt that was raked level instead of dug out and packed, or water running toward the house and softening the ground. So we dig down to firm subgrade, the ground the slab rests on, pack a gravel base in layers, and set the forms so the finished surface falls away from your foundation. If something has to give in your budget, I'd rather drop a fancy finish than thin the base, because nobody sees the base on day one and it's what decides whether the new slab ends up like the old one. Concrete still gets a few normal cracks, so we cut control joints, shallow grooves that give it a straight place to crack, before it has a chance to pick its own spot.
Rentals and commercial properties ask more of a slab because cars and delivery trucks cross it every day. On those we go thicker and set rebar, steel bars tied in a grid that hold the concrete together if it does crack, then give it a broom finish, a light brushed texture so tires and shoes grip. We keep traffic off until it has cured, the wait while it gains strength, because a slab driven on too early chips and cracks at the edges.

SeaTac concrete questions answered
How much does a new concrete driveway cost in SeaTac?
The cost comes down mostly to the size of the driveway and the tear-out and base work covered above. Access matters too, since a tight side yard or a long carry adds labor, and so does the finish, because a plain broom finish costs less than stamped or colored concrete. I'll measure it and list each of those parts in your written estimate.
Who do I call with permit questions for concrete work in SeaTac?
Call the City of SeaTac's Permit Center at 206-973-4750 or email permitcenter@seatacwa.gov. Its permit page lists building checklists for decks, drainage control, new homes or additions, remodels and re-roofs, so for a driveway, patio or steps, ask them directly what your job needs. On our jobs, we check which city or county office covers your address, take care of the permit when the job needs one and keep you posted on where it stands.
How do inspections work on a SeaTac building permit?
Each city permit lists the inspections it needs at different stages, and the permit holder schedules them. Work can't be covered until a city inspector approves it, and on a concrete job covered usually means poured over, so we don't pour until any required inspection has passed. Requests made before 10 p.m. are for a next-day inspection, which keeps a ready stage from sitting idle.
Does a concrete contractor have to be registered with the state in Washington?
Yes, Washington requires every construction contractor to register with the state Department of Labor & Industries, and state law requires them to be bonded and insured. On any home job of $1,000 or more, the contractor also has to give you the state's written disclosure notice to customers, and the same goes for commercial jobs from $1,000 to $60,000. We're fully licensed and insured, and it's fair to ask any contractor you're weighing about all of this before you sign.
Does a contractor from Kent need a SeaTac business license?
Yes, the city requires a business license for businesses inside city limits and for businesses that do work in SeaTac from somewhere else, which covers contractors based in Kent. The city works with the state's business licensing service, so a contractor can take care of the state and city licenses at the same time.
How do I get money back if a contractor caused me a financial loss in Washington?
If you're eligible, you can apply to Labor & Industries for a recovery payment for a financial loss caused by a construction contractor's work. Applications opened July 1, 2026, and the program is meant to give homeowners harmed by a contractor a path to getting money back.
