Union Hill-Novelty Hill lots, from pastures to neighborhoods
Union Hill-Novelty Hill is unincorporated country east of Redmond and north of Sammamish. Horse pastures sit beside smaller neighborhoods, and the paved Redmond Ridge Trail links up with dirt trails like Kari's Bog Trail. Redmond runs along the west side and around the Watershed Preserve in the north. On the pasture side, the calls we get are usually long gravel drives, barn aprons and shop slabs. In the neighborhoods it's more often patios, walks and garage floors.
Out here, distance and ground shape the job more than tight space does. A long drive or a slab out by the barn means a longer reach for the truck and more base to dig and pack. A lot with a rise to it means we plan where the water goes before we set a single form.
Concrete services for Union Hill-Novelty Hill properties
Concrete driveway building
Long gravel drives on pasture lots are a common call here, so we dig out and pack the base until it won't settle with the dirt.
Concrete patio construction
Behind newer homes in the neighborhoods, a patio usually sits close to the house, so we slope it to carry water away from the foundation.
Stamped concrete services
Stamped concrete gives a patio or walk the look of stone or slate, and it suits homes here where the yard opens onto pasture.
Concrete sidewalk building
A walk from the driveway to the front door, or out to a barn, needs a firm base and joints cut on time so it stays flat underfoot.
Garage floor concrete
We replace cracked or sunken garage floors and pour new ones in detached garages and shops. They slope toward the door so water drains out instead of pooling.
Decorative concrete
Colored and textured finishes work well on front entries and patios when you want something warmer than plain gray but still need a slab that drains.
Concrete retaining walls
Sloped lots here often need a wall to hold a cut for a driveway or patio, and we build drainage behind it so water doesn't push it over.
Concrete floor installation
For a barn, a workshop or a new room, we pour interior floors flat and level so flooring or equipment goes down without patching low spots.
Concrete pool decks
On lots with room for a pool, the deck has to give good grip and drain, so we set the slope before the pour and use a textured finish.
Concrete steps construction
Homes set above the road or on a rise often need new front steps. We build each step the same height, with a textured top for grip.
Slab foundation building
For a garage, shop or addition on a rural lot, we dig to firm ground and pack the base, because the whole building rides on it.
Foundation installation
New homes and additions on these lots get foundations laid out to the plan, with the forms set and checked before any concrete arrives.
Concrete parking lot building
Small property owners with a shop, a horse barn or shared parking get a lot graded to drain and poured thick enough for the vehicles it carries.
Concrete footings
Decks, sheds, carports and barn posts all need footings, the concrete pads that carry the weight down to firm soil. We dig them below the soft topsoil.
Foundation raising
When part of a slab or foundation has sunk, we lift it back toward level and look for the cause, which is usually water or soft ground underneath.
Concrete cutting
We cut openings, trenches and clean edges in existing slabs. That helps when a garage floor or driveway on an older property needs one section replaced.

Working in Union Hill-Novelty Hill: the county side of the job
Union Hill-Novelty Hill sits outside Redmond's city limits, so building permits here come from King County Permits, not the City of Redmond. The county issues permits to build, enlarge, alter, repair, move or demolish a building or structure. That covers work like a foundation or the slab under a garage. Its list doesn't name driveways or patios, so I check those with the county instead of guessing. If your job needs a permit, I tell you at the estimate. We handle the application and the inspection requests and keep the approved permit posted on site the way the county requires, and our pour date waits on the county's review.
Out here, the price mostly comes down to ground and access. How much soft soil comes out, whether the truck can reach the forms or we have to pump, whether old gravel or a cracked slab has to go first, and the finish you pick all show up in the number. The schedule turns on the permit, the concrete delivery and the cure. We do the same work in Mercer Island and back in Redmond, where lots are tighter, but here the job is more often a long drive or a barn slab than a small patio. The estimate gives you your own figure.
Soft ground and slopes on these lots
Pasture ground and yards that were filled in over the years are soft on top, and that decides how a driveway or patio holds up here. Most of the sinking, uneven slabs we get called about sat on a base that was raked level instead of dug out and packed, so they settled as the dirt underneath did. We dig down to the subgrade, the firm ground the slab sits on, pack a rock base over it and check where the water runs so the slab falls away from the house. If the budget's tight, I'd rather you go plain on the finish than thin on the base. You can redo a surface later, but you can't fix bad prep once the truck has left.
Parts of the area sit on slopes, and King County's landslide hazard map marks some spots as potential landslide hazard areas. The map doesn't say anything about the actual risk on any one lot. Depending on what you're building, though, a licensed geological engineer may be recommended to study the site, so if you're planning a foundation or a wall on a hillside, I'll raise it early.
How a concrete job runs in Union Hill-Novelty Hill
Here's how it goes from your first call to the day you get your driveway or patio back, and where the county fits in.
Call us or send the form
Call (425) 285-8289 or send the form, and we'll set a time to come out. Tell us roughly what you want poured and where it is on the lot.
I walk the site with you
I measure, look at where the water runs and ask how you'll use the space, so it helps if you're home for the visit. You get a written quote with each part of the job on its own line, so you can see what the base, the removal and the finish each cost.
We schedule, permit and pour
Once you say go, we set a date and handle the permit with the county if the job needs one, and the county's review can move that date. Our crew digs out, packs the base, sets the forms and rebar, which is steel that holds the slab together if it cracks, then pours and finishes with me on site.
Cut joints, cure, clean up
We cut control joints, grooves that give the slab a planned place to crack, and leave it to cure, the wait while it gains strength. I'll tell you when you can walk on it and when you can drive on it, and we clean up before we leave.
Questions about concrete work in Union Hill-Novelty Hill
(425) 285-8289Does a concrete slab for a small shed need a building permit in Union Hill-Novelty Hill?
Not always, but don't assume it's exempt. A county handout says the building code exempts certain structures under 200 square feet, and even those still have to meet every King County code requirement. I check your plan against that at the estimate and tell you what applies.
Do I need a permit to pour concrete in a floodplain in King County?
Yes. All development in a mapped floodplain needs a permit, and in unincorporated King County it goes through the county's permitting office as a floodplain development permit. You can look up your lot on the county's floodplain maps before we plan anything.
How do I know if the driveway for my new home adds county permit paperwork?
On a new single-family home, the county asks for additional submittal documents once the project has more than 2,000 square feet of new and replaced impervious surface, or 7,000 square feet of land disturbance. Impervious surface is paving that water can't soak through, and a long drive on acreage adds up fast. We tally it with you at the estimate, before the plans go in.
What is the best first step if a storm damages my foundation or slab in unincorporated King County?
Secure the site, then apply online at MyBuildingPermit.com for a damage assessment inspection. County inspectors report what they find and name any added permits the repair needs. Once you have that, call us to look at the concrete.
How much does a new concrete driveway cost in Union Hill-Novelty Hill?
Your cost is set mostly by the size of the drive, how much base work the ground needs and how heavy the traffic on it will be. A drive that carries trucks or a horse trailer needs a thicker slab and more steel than a walk, and stamped or colored work costs more than a broom finish, the brushed texture that gives you grip. Call (425) 285-8289 and I'll come price yours.
What causes concrete driveways to crack and sink in Union Hill-Novelty Hill?
The usual causes are a weak base, water running under the slab, joints cut late or skipped, and pours done in midday heat that leave a weak, dusty top. All concrete cracks some, so besides the base work above, we cut joints on time to put the cracks where we choose and schedule the pour so the finish sets right.

If you call while you're still planning, I can look at the ground and the slope before you settle on a size or finish, and that's cheaper than changing it later.
