Bellevue homes, hillside lots and the concrete around them
Bellevue is one of the cities we come down to regularly, and as a concrete contractor in Bothell, WA, most of our work here is flatwork, the driveways, patios, walks and steps around a house. The homes run from older ramblers and split-levels that still have their original driveways to newer, larger houses where the concrete is part of the design. The neighborhoods feel a lot like the ones we work in next door in Kirkland and Redmond.
Plenty of those lots slope toward the street or away from it, and many of the older driveways have settled or cracked over the years. So the planning on a Bellevue job usually starts with the slope and the ground, long before the pour.
Concrete work we do for Bellevue properties
Concrete driveway building
When a Bellevue driveway has sunk or split, we dig out, pack a new base and give it a broom finish, a light texture for grip on slopes.
Concrete patio construction
A backyard patio on a sloped Bellevue lot needs to fall away from the house, so we set the grade for drainage before we pick the finish.
Stamped concrete services
Stamped concrete gives a Bellevue patio or entry the look of stone or brick, with the same careful base underneath as a plain slab.
Concrete sidewalk building
Front walks on older Bellevue homes often heave or settle into trip edges, and we replace them with a packed base and joints cut where cracks belong.
Garage floor concrete
An older Bellevue garage floor that's cracked or stained can be broken out and repoured, sloped toward the door so water off a car runs out.
Decorative concrete
Colored and textured finishes suit the newer Bellevue homes where the concrete is part of the look, from entry courts to the edges of a patio.
Concrete retaining walls
On Bellevue's sloped yards, a concrete retaining wall holds back the hill to make room for a level patio or parking, built on a proper footing.
Concrete floor installation
Basements, shops and additions on Bellevue properties need an interior floor that's flat and dry, so we prepare the base and moisture layer before the pour.
Concrete pool decks
A Bellevue pool deck has to drain away from the water and stay comfortable underfoot, so we slope it and pick a finish that isn't slick when wet.
Concrete steps construction
Split-level and hillside homes here often have several runs of entry steps, and we form each rise evenly so you're not catching a toe on an odd one.
Slab foundation building
For a garage, shop or addition on a Bellevue lot, a slab foundation starts with leveling the ground and packing the base, often after cutting into a slope.
Foundation installation
New foundations for additions and rebuilds on Bellevue properties are laid out from the plans, dug to firm soil and poured with steel set where it belongs.
Concrete parking lot building
Small Bellevue property owners call us for parking areas behind shops and multi-unit buildings, where the base and drainage take more traffic than a home driveway.
Concrete footings
Footings carry decks, walls and additions, and on Bellevue's sloped ground we dig them to undisturbed soil so the weight above stays put.
Foundation raising
When part of an older Bellevue house has settled and doors start sticking or floors slope, foundation raising lifts it back toward level and supports it there.
Concrete cutting
We saw-cut old Bellevue slabs for clean removal, new drains, utility lines or a wider driveway, so the concrete you keep has a straight edge.

Permits and licenses on Bellevue concrete jobs
Permits in Bellevue go through the city's Development Services department, where the building official issues the permit required before anyone builds, alters or repairs a structure, and where plans are reviewed and the work is inspected. When your job needs one, the start date waits on that review, so I look at the permit side when I come out for the estimate, and we can prepare and file it with the city and plan the start around it. The city also asks for the contractor's Washington State contractor license and Bellevue business license before it issues a construction permit, so those are the two licenses worth checking with anyone you hire, and we're licensed and insured.
The price of a Bellevue job usually comes down to a few things: the size of the slab, how much old concrete comes out, how much digging and base work the ground needs and the finish you choose. The schedule turns mostly on any permit review and on curing, the wait after the pour while the concrete gains strength. Access matters here too, since a driveway we can reach with the truck pours very differently from a backyard patio on a hillside lot that we reach along the side of the house. We handle these questions the same way in Kenmore and the other cities around Bothell, and your written estimate puts each piece on paper so you can see what you're paying for.
Why Bellevue driveways and patios settle and crack
A lot of the cracked and sunken concrete we're asked to replace in Bellevue was poured years ago on dirt that was raked level rather than dug out and packed, so the slab settled right along with the ground. When we replace it, we dig down to firm subgrade, the ground the slab actually rests on, and build up a packed base before any forms go in.
Sloped lots move water, and a slab that tips toward the house sends it toward your foundation, so we check where the water runs and set the fall away from the house before the pour. City guidance also says landscaping on a property with critical areas, such as steep slopes, wetlands or streams, needs a permit, so if your lot has one, I'll raise it when I come out.
How a Bellevue concrete job runs, from call to walkthrough
Here's how a job goes from your side, from the first call to the day we walk the finished concrete together.
Call or send the form
You call (425) 384-1147 or send the form, and we get back to you to set up a time for me to see your property.
I look at your site
I come out myself, look at the ground, the slope and where the water runs, and ask what the space needs to do. You get a written estimate that spells out what's included and what isn't, so you know exactly what you're paying for before you decide.
We set a date and pour
Once you're ready, we sort out any permit with the city and set a date that allows for its review. Our own crew does the digging, base, forming and pour, and I lead the work on site.
We walk the job together
When the concrete is finished, we walk it with you and go over the curing wait before you walk or drive on it. If anything looks off to you, that's the time to say so, and we'll talk it through right there.
Questions about concrete work in Bellevue
How do I find out if my concrete project needs a permit in Bellevue?
Start with the city's list of work requiring permits, and for concrete pay closest attention to its landscaping limits, which call for a permit once total digging or fill passes 50 cubic yards or disturbed ground passes 1,000 square feet. A large driveway tear-out and repour can reach those numbers, so I measure the area at the estimate and we talk through where your job stands.
Does a concrete retaining wall need a permit in Bellevue?
City guidance says it does when the wall is over four feet tall, measured from the bottom of the footing to the top of the wall, or when it holds back a surcharge, extra weight such as a driveway or a slope above it. On Bellevue's hillside lots that second case comes up often, so I look at what sits above a planned retaining wall before we price it.
When does a contractor need a Bellevue business license?
A contractor needs one once it has an office or place of business in Bellevue, or brings in $4,000 or more in the city in a year, and it needs a Washington State Business License before that. It matters for your job because the city asks for it before issuing a construction permit, which is why it's one of the two licenses worth asking about.
What affects the cost of a concrete driveway in Bellevue?
After size, the biggest price drivers on a Bellevue driveway are how thick the slab needs to be for your cars, whether it gets rebar, the steel grid inside that holds cracks tight, and how much forming and grading a sloped lot takes. When a budget gets tight, people often want to trim the base first because nobody sees it once the concrete is down, but I'd rather save on the finish, since a nice surface over a weak base still sinks and fixing the base later means tearing it all out. Your written estimate lists each of these so you can decide where the money goes.
How long do I have to stay off a new concrete driveway in Bellevue?
You can usually walk on new concrete well before you can drive on it, and I'll give you both dates for your pour when we schedule it. That wait is the curing time, and putting a car on the slab too early is one of the easiest ways to crack a new driveway.
How do I keep a new concrete patio in Bellevue from cracking?
Concrete can still crack, but you keep the cracks small and straight with control joints, grooves cut into the slab so it cracks along a line we choose, cut on time instead of days later. Pour timing matters too, because concrete finished in the heat of the day can end up with a weak, dusty top, and none of it holds up without the dug-out, packed base described earlier.
