Redmond concrete work, from older driveways to hillside lots
We're based in Redmond, so a lot of our calls come from right here. We replace cracked driveways and patios at older ranch and split-level houses, redo walks and steps at newer subdivision homes, and set footings and slabs for garages and backyard cottages. We also pour flatwork, the lots and walks that lie flat on the ground, for small offices and rentals. The work looks much the same just south in Bellevue and southeast in Sammamish.
What changes from one street to the next is the ground. Some lots are flat, plenty of them slope, and nearly all of them stay wet through the winter, so the dig-out and the drainage plan usually decide more about the job than the size of the slab does.
Concrete services we do for Redmond homes and lots
Concrete driveway building
Many older Redmond driveways have cracked or sunk at the garage edge. We dig out the soft base, pack new rock and pour a slab that sheds water.
Concrete patio construction
Patios here stay wet for months, so we slope them away from the house and use a broom finish, a light texture that grips when it's damp.
Stamped concrete services
Stamped concrete gives a patio or front walk the look of stone or brick in one solid slab, and we seal it to stand up to wet winters.
Concrete sidewalk building
When tree roots have heaved the walk to your door into trip edges, we cut out the bad sections and pour new ones flush with the rest.
Garage floor concrete
Cracked, sunk or dusty garage floors usually need replacing. We pour the new slab with a slight tilt toward the door so water from wet cars runs out.
Decorative concrete
Colored or stained concrete lets an entry or patio match your siding and stone trim. We pick the color with you on site, held against the house.
Concrete retaining walls
Sloped Redmond yards often need a wall to hold back soil for a flat patio or parking pad. We put drainage behind it so water doesn't build up.
Concrete floor installation
Shops, outbuildings and basements here sit on wet ground, so we lay a plastic sheet under the slab to keep moisture from coming up through the floor.
Concrete pool decks
Between splash and rain, a pool deck here is rarely dry, so we give it a texture that grips bare feet and slope it away from the pool.
Concrete steps construction
Front steps that lean away from the house usually sit on settled ground, so we pour new ones on packed rock with every step the same height.
Slab foundation building
For a detached garage or backyard cottage, a slab foundation is often the simplest start, and we set the steel and base to the approved plans.
Foundation installation
Additions and new homes on Redmond's sloped lots often need stepped foundation walls. We form and pour them to the approved plans, with drainage at the footing.
Concrete parking lot building
We replace cracked, puddled lots for small offices and rental properties in sections, so part of the lot can stay open while we work.
Concrete footings
Decks, additions and carports start with footings, the concrete pads that carry the weight, and we dig them to firm ground and the depth the plans call for.
Foundation raising
When one corner of a house or garage has dropped and doors start to stick, we look at what's moving under it before we lift and support it.
Concrete cutting
We saw openings in existing slabs for new drains, doorways or utility lines, and cut out cracked sections of a driveway or walk so only those get replaced.

Permits and pricing for concrete work in Redmond
Building permits here come from the City of Redmond's Development Services Center, which covers new homes, additions, garages and the slabs and foundations that go with them. When a job needs one, the permit usually sets the start date, because the city won't release it until it's paid for and the contractor and current city business license details are on file where they apply. That gives you an easy check on whoever you hire, since a contractor should have those details ready. If a request about your permit ever looks off, the city says to ignore it and confirm through its verified contact information.
We're licensed and insured, and if your job needs a permit we tell you at the estimate, then handle the application and the inspection requests ourselves. Price here moves mostly with the slab's size, what's under it and how hard the site is to reach on a steep or tight lot, and the estimate is where you get your own number. The schedule turns on the permit and the rain, because I'd rather move a pour date than put concrete on a soaked base. We do the same work in Kirkland and the other cities around Redmond.
What Redmond's rain and slopes do to concrete
Water is behind most of the calls we get here. Months of rain soak the subgrade, the ground a slab sits on, and if the old slab was poured on dirt that was raked level instead of dug out and packed, that ground softens and the slab sinks, cracks and starts to pool water. We dig down to firm soil, pack crushed rock in layers and check where the water runs before we set the forms, so the new slab falls away from the house instead of toward it.
Hillside lots and big trees do the rest. Steep driveways and side yards need walls and steps that hold the ground back, and roots lift walks and patios over the years, so we look at both before we quote and reroute a walk when that makes more sense than fighting the tree.
How a concrete job runs when you call us in Redmond
Here's how a job runs from your side, from the first call to the day you can use the new slab.
Tell us about the job
Call (425) 285-8289 or send the form and tell us what's cracked, sunk or missing. We set a time for me to come out and look.
I measure and write the quote
I walk the lot, measure, check where the water runs and ask how you'll use the space, so it helps if you can be there. You get a written quote with each part of the job on its own line, so you can see what the base, the concrete and the finish each cost.
We book the date and permit
Once you say go, we set a date and file for the permit if the job needs one. A permit technician at the city emails next steps once the application is complete, so on permit jobs the pour date waits on that email.
I run the job on site
Our crew digs out, packs the base, pours and finishes, and I'm on site running it from the prep to the cleanup. We call in any inspections the permit needs and tell you when the slab is ready to walk and drive on.
Questions about concrete work in Redmond
(425) 285-8289How much does a new concrete driveway cost in Redmond?
Most of a Redmond driveway's price is in what you can't see, which is how much old concrete comes out and how much digging and packed rock it takes to reach firm ground on a wet or sloped lot. Size, truck access and the finish come next, since color and stamping cost more than a plain broom finish. If the budget's tight, cut the finish before the base, because a plain slab can be dressed up later and bad prep can't be fixed once the truck has left.
Do I need a permit for a concrete driveway or sidewalk in Redmond?
The city's list of work that needs no building permit names driveways and sidewalks, but that's not the end of it. An exemption doesn't allow work that breaks the city's code, and work that changes the public sidewalk or street, blocks traffic or uses on-street parking falls under the city's Right-of-Way Use Permit. I look at where your driveway meets the street when I come out.
Does a concrete retaining wall need a permit in Redmond?
Not if it's 4 feet or less, measured from the bottom of the footing to the top of the wall, and isn't holding up a surcharge, extra weight such as a driveway, a slope or a building above it. Because that 4 feet includes the buried footing, a wall that looks about 3 feet tall can be closer to the limit than you'd think. I measure it out at the estimate so you know before we start.
How deep do concrete footings need to be in Redmond?
The city's residential code lists a frost line depth of 12 inches for Redmond, which is how deep the ground can freeze, so footings need to sit below it. The same code puts the city in Seismic Design Category D2, one of the higher earthquake categories, so foundation plans here have to meet the code's earthquake rules. We dig to that depth or to firm soil, whichever is deeper, and if the ground looks wrong I'll say so and find out before we pour.
How long does new concrete need to cure before I can drive on it?
Usually about a week before you drive on it, and a day or two before you walk on it. Curing is the slow hardening that keeps going for weeks after the pour, and cool weather slows it, so we tell you the day for your slab and ask you to keep heavy trucks off longer.
What causes a concrete driveway to crack and sink in Redmond?
Most of the time it's the base, when dirt was raked level instead of dug out and packed and then settled with the rain. Water running toward the house, a pour in midday heat that leaves a weak, dusty top, and control joints, the grooves cut to give cracks a straight place to go, cut late or skipped all add to it. We pack the base, cut joints soon after the pour and set rebar, steel bars inside the slab that hold any cracked pieces together so they don't drift apart.
