Redmond homes and the ground under them
Most of our work in Redmond is flatwork, which means the driveways, patios and walks that lie flat on the ground, along with steps and the occasional garage slab. The houses range from older homes whose original driveways have been settling for decades to newer ones on tighter, hillier lots. The calls we get here look a lot like the ones we answer in Kirkland and Woodinville.
What usually shapes the job here is the lot itself. A slope decides where the water runs and where a slab can sit flat, and a narrow side yard or a steep drive decides how the concrete gets to the back, so I look at both before I write anything down.
Concrete work we do for Redmond homes
Concrete driveway building
When an old driveway has sunk or sends water toward the garage, we dig out to firm ground, pack a new base and pour a slab built for cars.
Concrete patio construction
On a sloped backyard, a patio needs level footing and a gentle fall away from the house, so we plan the grade before we set any forms.
Stamped concrete services
Stamped concrete gives a patio or walk the look of stone or brick in a single pour, and we put the same base work under it as a plain slab.
Concrete sidewalk building
We replace front walks that have heaved over roots or settled into trip edges, and we pour new paths that keep you off wet lawn all winter.
Garage floor concrete
A cracked or pitted garage floor can come out and go back in with a slight fall that sends winter drip toward the door, not your storage.
Decorative concrete
Colored concrete, exposed aggregate and custom borders can dress up an entry or patio, and I'll tell you plainly which finishes hold up best through a wet season.
Concrete retaining walls
On hillside lots, a concrete wall can hold back a slope and make room for a flat yard, with drainage behind it so water doesn't push it out.
Concrete floor installation
For basements, shops and outbuildings, we pour interior floors on a packed base with a vapor barrier underneath, so the floor stays flat and drier.
Concrete pool decks
A pool deck needs a surface with grip and a fall away from both the water and the house, and we plan both before the first truck arrives.
Concrete steps construction
We rebuild front and back steps that have tilted, crumbled or pulled away from the house, with even risers and footings set deep enough to stay put.
Slab foundation building
For garages, shops and additions, we build slab foundations on ground we've dug out and packed, with the steel and thickness the plans call for.
Foundation installation
When you're adding on or building new, we form and pour the foundation to the approved plans and keep you informed as each stage is checked.
Concrete parking lot building
For small commercial lots and shared driveways, we pour concrete that stands up to daily traffic and drains to where the water is meant to go.
Concrete footings
Decks, posts, sheds and garden walls all start with footings, and we dig them to the depth the job and the ground call for, then pour them solid.
Foundation raising
When part of a foundation or slab has dropped, we find out why it moved first, because lifting it without fixing the cause usually means doing it twice.
Concrete cutting
We saw-cut clean openings for new doors, drains and utility lines, and we cut out damaged sections of driveway so new concrete ties in neatly.

Working in Redmond: permits, checks and access
In Redmond, construction permits come from the city's Development Services Center, and when your job needs one, we prepare and file it and plan the start date around the city's process. When a permit is picked up, the city asks for the contractor's information and current City of Redmond business license information where that applies, so it's reasonable to ask any contractor about those before you sign. We're licensed and insured, and I'm glad to go over it with you. If anyone asks you for permit fees or paperwork in the city's name, the city suggests ignoring the request until you've confirmed it through contact details you've looked up yourself.
The street matters too, because the city has a separate right-of-way use permit for work that changes things in the public right-of-way or uses the street, on-street parking or the public sidewalk, and that can come into play when a concrete truck needs room out front. The price here mostly turns on what's under and around the slab, such as soft ground to dig out, a slope, how close the truck can get and an old slab to break up. The schedule turns on the permit side, the weather and the delivery, and your written estimate covers your own figures. We do the same work across the cities around Bothell, from Bellevue to Shoreline.
Why sloped Redmond lots are hard on concrete
Our long wet season and the slope on so many lots here work together against a slab. Rain runs downhill across the yard, collects against the low edge of a patio or driveway and softens the ground underneath, which is where most pooling water and sinking corners start. Before we set a single form, I watch where the water goes on your property, and then we slope the new slab away from the house and add drainage where the ground needs it.
Mature trees cause the rest of what we see. Their roots lift walks and driveway edges over the years, and pouring back in the same spot usually brings the same result, so we talk with you about where the new slab should sit and how to keep it clear of the roots.
How a concrete job runs when you call us from Redmond
From your first call to the final walkthrough, you'll deal with me directly, and you'll know what's planned before any concrete is ordered.
Call us or send the form
Tell us what you have in mind and roughly where it goes on the property, and we'll set a time for me to come out. You don't need measurements or drawings.
I look at the site
I check the ground, the slope, where the water runs and how the truck will reach, and I ask what the space needs to do for you. The written estimate then lists what's included and what isn't, so you know exactly what you're paying for before you decide.
We handle permits and scheduling
If your job needs a permit, we prepare and file it, and once the city finds the application complete, a permit technician emails the next steps. We set your start date around that and let you know when the crew will arrive.
We pour and walk it together
Our own crew digs out, packs the base, sets the forms and steel, then pours and finishes the slab, and I lead the work on site. When it's done, we walk the finished job with you so you can see every part of it.
Questions about concrete work in Redmond
Do I need a permit for a new concrete driveway in Redmond, WA?
The city's residential permits page lists driveways and sidewalks among the work that doesn't need a building permit, but that doesn't settle every job on its own. The city's code says an exemption doesn't allow work that breaks the code or other local rules, and anything not on the no-permit list needs a building permit. I look at the permit side when I come out for the estimate, so you'll know where you stand before we set a date.
Does a concrete retaining wall need a permit in Redmond?
Under the city's code, a retaining wall 4 feet tall or less, measured from the bottom of the footing to the top of the wall, doesn't need a permit unless it carries a surcharge, which is extra weight pressing on it, like a driveway or a slope rising behind it. Taller walls, and short ones carrying that kind of load, need a permit. When yours does, we prepare and file it for you.
How deep should concrete footings be in Redmond, WA?
Redmond's residential code lists a frost line depth of 12 inches, so footings for steps, walls and small structures usually go at least that deep, below the ground that can freeze and push them up. Some jobs call for deeper footings because of their size, the plans or soft soil, and I check that at the estimate.
How much does a concrete driveway cost in Redmond?
The cost of a Redmond driveway is set mostly by its size, how much digging and base work it needs and the finish you choose, and your written estimate spells out what's included and what isn't. If the number comes in higher than you planned, I'd suggest a plain broom finish, the lightly brushed texture that gives shoes and tires grip, before trimming the base. The base is what keeps the slab from settling, and you can't add it once the concrete is down.
How long does a new concrete driveway need to cure before I can drive on it?
You can usually walk on a new driveway after a day or two and drive a car on it after about a week, though cool, damp weather can stretch that. Curing is the slow hardening that keeps going well after the pour, so heavy trucks should wait longer, and I'll tell you when yours is ready.
What causes concrete driveways to crack and sink in Redmond?
Most of the cracking and sinking we see comes from a base that was raked level instead of dug out and packed, so it settles as water works through it. Joints cut late or skipped let a slab crack wherever it likes, so we dig down to a firm subgrade, the soil the slab rests on, pack a gravel base, add rebar, the steel bars that hold the concrete together, and cut control joints, shallow grooves that give cracking a straight line to follow. Concrete can still crack, but those steps keep the cracks small and in places we chose.
