Bothell homes and lots as we see them
Bothell is a growing city that straddles the King County and Snohomish County line, right next to Kenmore and Kirkland, where we're based. Most of what we do here is flatwork, meaning the driveways, patios, walks and garage floors that lie flat on the ground. The houses run from older places with a driveway that's been patched more than once to newer homes where the builder's slab has started to crack or drop at the garage.
Plenty of lots here slope toward the street or down the back. So the job usually starts with how much ground has to come out and where the water will go once the slab is in.
Concrete work we do for Bothell homes
Concrete driveway building
When a Bothell driveway has sunk at the garage or cracked across the middle, we tear it out, pack a new base and pour a slab that drains.
Concrete patio construction
A patio on a sloped backyard here needs the ground cut level and the slab tipped away from the house, so water runs off instead of pooling.
Stamped concrete services
Stamped concrete gives a Bothell front walk or patio the look of stone or brick in one pour, and we seal it to protect the color.
Concrete sidewalk building
A front walk that's heaved or tipped is a tripping spot, so we replace it on a packed base with joints cut where the cracks should go.
Garage floor concrete
Older garage floors here often have cracks and a low spot that holds water, and a new slab sloped toward the door takes care of both.
Decorative concrete
Decorative concrete covers colored, exposed-aggregate and scored finishes. It's a good fit when you want a patio or entry that matches the house instead of plain gray.
Concrete retaining walls
On sloped lots here, a concrete retaining wall holds the hill back so you get a flat yard, and we put drainage behind it so water doesn't build up.
Concrete floor installation
We pour interior slabs for basements, shops and additions, with a plastic sheet under the concrete to keep ground moisture away from the flooring you put on top.
Concrete pool decks
A pool deck needs a finish that grips when it's wet and a slope that sends splash water away from the pool and the house.
Concrete steps construction
When front steps have pulled away from the house or crumbled at the edges, we tear them out and rebuild them with steel inside and every step the same height.
Slab foundation building
For a garage, shop or addition on a Bothell lot, we pour slab foundations on dug-out, packed ground with steel set in the concrete to hold it together.
Foundation installation
We dig and pour footings and foundation walls for additions and new structures to the plans, because everything built above depends on them being level and square.
Concrete parking lot building
For small commercial or rental properties, we pour concrete parking areas with a thicker slab and drainage planned so water doesn't sit in the lot.
Concrete footings
Decks, fences, posts and small additions need footings dug to firm ground, and we pour them so the load sits on solid soil instead of loose fill.
Foundation raising
When part of a slab or foundation has dropped, foundation raising lifts it back toward level. Before we lift anything, we find out why it sank.
Concrete cutting
We saw-cut openings for doors, drains and utility lines. We also cut out damaged sections of a driveway or patio cleanly, so the new pour meets a straight edge.

Working in Bothell: permits, prep and price
Permits in Bothell come from the city's Permit Center, which handles projects of every size, from home repairs to new commercial buildouts. The city says new construction and repairs to existing structures generally need a permit. So whether your driveway or patio needs one is the city's call, and I check before we set a start date. When one is needed, we can file it for you or help you file it, and we plan the start around the approval and the inspections. We're licensed and insured.
What moves the price in Bothell is mostly the work nobody sees later: how much old concrete has to come out, how deep we dig to reach firm ground, how much base goes in and gets packed, and whether a slope needs extra forms or a short wall. The schedule depends on the permit, if there is one, and on having the ground ready before the truck comes. The written estimate puts your own figure on all of it. We're a concrete contractor in Kirkland, WA, and we do the same work across the cities around Bothell, from Woodinville to Kenmore.
Why Bothell driveways and patios crack and sink
Most of the cracked or sunken slabs we look at here have the same problem underneath. Sometimes somebody raked the dirt flat instead of digging it out and packing a real base, so the slab settled along with the ground. Other times the subgrade, the soil the whole slab sits on, went soft because water kept running under it. On a sloped lot that water has to go somewhere, and if nobody checked, it goes toward the house. We dig to firm ground and pack the base. Before any concrete arrives, we set the slab to fall away from the house.
The other half of the problem is cracks in the wrong places. Concrete shrinks as it dries. So we cut control joints, shallow grooves that give it a straight line to crack along, instead of leaving it to pick its own spot.
What to expect when you hire us for concrete in Bothell
Here's how it runs from your first call to the last walk-through, with the permit worked in where your job needs one.
Call or send the form
Call (425) 285-8195 or send the form with a few lines about the job and your address, and we'll set up a time for me to come out. You don't need measurements, just what you want and what's wrong with what's there now.
I look at it with you
I come out myself and look at the old slab, the slope and where the water runs with you. I also check which office covers your address, and then you get a written estimate, so you're deciding on real numbers instead of a phone guess.
We prep, pour and finish
Once any permit is approved, we dig out, pack the base and set the forms before the concrete truck shows up, and I'm on site with our crew for the pour. We finish the surface and cut the joints the same day.
Walk the finished job together
When it's done, we walk it with you and go over curing, the waiting period while the concrete gains strength before it can take foot traffic or a car. We'll tell you when it's ready for feet and when it's ready for the car.
Questions about concrete work in Bothell
Do I need a permit to pour a concrete driveway in Bothell?
It may need one, because the city's list of permit-exempt work doesn't name driveways, patios or walks. The digging has its own rule, too. The city exempts excavation under 50 cubic yards from a grading permit when it's under two feet deep or doesn't cut a slope steeper than two feet across for every foot down. That means a big tear-out on a hillside lot is worth asking about.
Does a concrete retaining wall need a permit in Bothell?
A wall up to four feet tall, measured from the bottom of the footing to the top of the wall, is on the city's exempt list. That doesn't apply if the wall holds up extra load or holds back fuel or similar flammable liquids. Extra load means things like a driveway, a parked car or more slope sitting behind the wall, which is common on hillside lots here. Taller walls, or walls with that kind of weight behind them, are a question for the city before we build.
How do I apply for a building permit in Bothell?
You apply online through MyBuildingPermit.com, because the city takes all permit and land use applications there and only there. If you want to ask questions in person first, the Permit Center takes walk-ins Monday to Thursday from 8 a.m. to noon and 1 to 4 p.m., and Fridays from 8 a.m. to noon.
How much does a new concrete driveway cost in Bothell?
Your price comes from the size, the tear-out and the base work, plus the finish you choose, and the finish is the one part you can scale back without regret. A stamped or colored surface costs more than a plain broom finish, a light texture dragged across the top so shoes and tires get some grip. If you need to trim the budget, trim the finish and keep the base. Nobody sees the base on day one, but everybody sees it when the slab sinks. The written estimate after my visit gives your number.
Do I need a permit to take out a tree for a new patio in Bothell?
Generally not on a single-family lot, as long as every one of the city's conditions applies. The lot has to be an existing lot of record under 20,000 square feet, and more than five years have to have passed since the subdivision was established. The site also can't have critical areas like wetlands, streams, slopes steeper than a 40% grade or a shoreline designation. If any of those don't fit, check with the city before the saw comes out.
How do I find my property line before pouring a driveway in Bothell?
Start with CobMap, the city's interactive map, which shows approximate property lines and critical areas for your lot. For an exact line, you need a survey, and ordering one is your call. If a driveway or wall will run near the edge of the lot, I'd want the line settled before we set forms.
