Concrete contractor in Woodinville, WA - slabs that drain and sit flat
Kirkland Concrete Company is a concrete contractor based in Kirkland that pours driveways, patios, walkways, steps and garage floors for homeowners in Woodinville, inside city limits and out in the county areas around it.
Woodinville as we see it on concrete jobs
Woodinville covers more ground than most people picture when they hear the name. The city is one piece of it, but a lot of houses with a Woodinville address sit out in the county, up on the hills or north toward Maltby. Down in the valley you've got the river trail and the wineries everybody knows, and up the slopes you get bigger lots, long driveways and older houses whose concrete has had years to settle into the ground.
That mix is what shapes the job. On a sloped lot the first question is where the water goes once the slab is down, and on flatter ground it's whether the base underneath will keep the slab level.
Working in Woodinville: permits, licenses and what sets the price
Who issues your permit depends on which side of the city line you're on. Inside city limits it's the city's Development Services, which also does the review and inspections, and in the Snohomish County part of Woodinville it's Snohomish County Planning and Development Services. We don't pour until that review clears, so your start date waits on it. There are also two things you can check about any contractor here. Washington requires every construction contractor to register with the Department of Labor & Industries and to be bonded and insured. The city also requires a business license, and it says a business based outside Woodinville needs one once its yearly income in the city goes over $2,000. The state revenue department's page lists no license needed up to $4,000 and a $39 fee above that.
We're licensed and fully insured. When your job needs a permit, I tell you at the estimate, and we either take care of the application with the city or county or walk you through it so you know where it stands. As a concrete contractor in Kirkland, WA, we see the same thing on hillside lots here as out toward Cottage Lake or down in Bothell. The price comes down to how big the slab is, whether old concrete has to come out first, how much digging and base work the ground needs, how close the truck can get and the finish you pick. Your estimate puts a figure on it for your lot.
What Woodinville lots and houses ask of new concrete
Plenty of the calls we get from around here start with a driveway that's cracked, sunk at one end or holding a puddle by the garage. Usually the cause is underneath. Either the base was raked flat instead of dug out and packed, or the slab falls toward the house. So before any forms go up, we dig out the soft material and pack a solid subgrade, the layer the slab sits on. Then we set the slope so water runs to the street or the yard. Older houses here often have a tired garage slab too, and garage floor concrete gets the same care with the base. If you have to cut the budget somewhere, I'd rather you go plainer on the finish than skimp on the base, because nobody sees the base on pour day but it's what decides how the slab looks years later.
Some lots sit on steep or erosion-prone ground that the city treats as a geologically hazardous area, land it says isn't suitable for structural development. If your property is near one, we look into that before planning anything heavy, because concrete on ground that moves won't stay put.

Call or send us a note
Call (425) 285-8643 or use the form, and tell us the address and what you're after. The address matters here because it tells us whether you're in the city or the county.
I walk the site myself
I look at the slope, the old concrete and where the water goes, and hear what you have in mind. Then I walk you through the plan and the estimate.
We sort out the permit
If the job needs a permit, we file it with the city or county or walk you through it. The review has to clear before we set a pour date.
Dig, pack and set forms
Our crew digs out, packs the base and sets the forms and any rebar, the steel inside that helps hold the slab together, well ahead of the concrete truck. You'll want cars and anything stored on the old slab moved before we start.
Pour, finish and let it cure
I run the crew through the pour, the broom finish that gives you grip when it's wet, and the control joints, cuts that give the slab a planned place to crack. Then the slab cures, a wait while it gains strength, and we tell you when it's ready to walk on and drive on.

Woodinville concrete questions homeowners ask us
Is my Woodinville WA address inside city limits or in the county?
Not necessarily inside the city, because a Woodinville mailing address doesn't mean the house is in the city, and more than half of the 98072 ZIP code is in unincorporated King County or Snohomish County. It matters because it decides whose rules your job falls under. We confirm it from your address before I come out.
How much does a new concrete driveway cost in Woodinville?
It depends on your lot more than anything, so we price each driveway after seeing it rather than putting a number on this page. On a sloped Woodinville lot, tearing out the old slab and the digging and drainage work usually move the price more than the finish does. I put a figure on it once I've walked the site.
How do I apply for a building permit in the City of Woodinville?
Inside city limits, most applications go through the city's Permit Portal, where you can submit applications and revisions, pay fees, schedule inspections and track the project. If your job needs a permit, we handle the filing or walk you through the portal with you.
What should a contractor give me before a home concrete job in Washington?
On any home job of $1,000 or more, Washington requires the contractor to give you the Department of Labor & Industries' disclosure statement. It goes along with the state registration covered above, so if a contractor skips it, take note.
Which building code applies to concrete work in Woodinville?
Washington's state building code applies in every city and county, and the residential part in use now is the 2021 International Residential Code with the state's own changes. The state's building code council says the 2024 codes take effect May 3, 2027.
What causes a concrete driveway in Woodinville to crack and sink?
Most cracking and sinking comes from what's under the slab and how it was poured, not from the concrete itself. A base that settles, water getting under the edge, a midday pour that leaves a weak, dusty top, and joints cut late or skipped all show up later as cracks in places nobody chose. Concrete still cracks some, which is why we cut the control joints where a crack can run without showing.
