Old patio sinking, or water pooling by the back door? We pour one that drains away from the house, with joints where cracks belong.
Concrete patio construction in Redmond means building a new outdoor slab from the dirt up. We dig out and pack the ground, slope the slab so water runs away from your house, and cut joints so any crack lands in a groove you won't notice.
Most calls start with bare lawn off the back door that turns to mud every fall, or an old patio that's cracked, sunk at one corner or tipped toward the house. The price mostly turns on the size, how much digging and base work your ground needs, whether an old slab has to come out first, sometimes with concrete cutting along the house, and how plain or decorative you want the top. The schedule turns on the weather and on what your city needs before we can set a date, and I'll give you a price for your own yard when I come out to look.
When you call, I'm the one who walks your yard, asks about the old patio and works out the price. The crew that does the work is our own, and I run the job from the first shovel to the last joint cut.
We've been in business since 2013, and I learned the trade by asking older finishers a lot of questions and breaking up old slabs to see what went wrong. I'd rather spend extra time on why your old patio sank than pour a new one that sinks the same way.
We're licensed and insured. Washington requires construction contractors to register with the state, so you can look us up, or anyone else who bids, with the Labor & Industries contractor lookup. Then call (425) 285-8618 and I'll set up a visit.
Send us the rough size in square feet, a few photos of the yard and when you'd like it done, and we'll reply within one business day to set a time. I come out myself to measure, check where the water goes and walk you through the price, and there's no obligation to go ahead.
The city of Redmond keeps a list of building work that doesn't need a permit, and it names sidewalks and driveways but not concrete patios, so that list doesn't settle whether your patio needs one. Before we set a date, we find out which city or county office covers your address and what your project calls for, then tell you plainly who'll handle the permit and the inspections. We're based in Redmond and do the same work in Kirkland, Sammamish and the other cities around it, and if your city isn't on our pages, just ask.
Redmond's building code rates the risk of weather damage to concrete here as moderate and designs for winter temperatures down to 27°F, so a patio here goes through freezes every winter. Outdoor slabs that freeze need air entrainment, tiny bubbles mixed in that give freezing water room to expand, and because the plant sets the mix, we put it on the concrete order from the start. On pour day the truck won't wash out on your lawn or in the street, since the city's stormwater rules keep washout off-site or in a set-aside spot, away from storm drains, ditches and streams. Most yards we see around here stay damp much of the year, which is why drainage is the first thing I look at.
An installed concrete patio in Seattle usually costs about $8 to $18 per square foot, and that's the closest price guide we have for this area. That figure covers the finished job, not just the concrete. Your own Redmond price comes from the estimate, with the ground prep broken out as I described above.
You keep it from cracking in the wrong places by cutting control joints deep enough and soon enough, on ground that's firm and even. A slab with no joints, or with joints cut too shallow or too late, cracks wherever it wants. Soft spots, loose dirt in old utility trenches or buried roots and sod make a slab settle and crack no matter how good the joints are, so our crew digs those out before we form anything.
The best way is to work out the drainage before the pour, because in the Pacific Northwest a patio on a poorly drained base grows moss, heaves and wears at the surface much faster than in drier places. At the estimate I look at where your roof and yard send water, and we set the slope from that so nothing sits against the house.
Yes, as long as protection is planned in, because it counts as a cold-weather pour once the air drops to 40°F or is expected to while the concrete is fresh. Cold slows the set and can freeze the concrete before it's gained its strength. If your date lands in late fall or winter, I'll tell you what we'd do to protect it, or whether it's smarter to wait for spring.
Skip deicers the first winter and use sand if you need traction, which is what one concrete trade group's guide advises. After that, the same guide says to keep magnesium chloride, calcium chloride, fertilizer and water-softener salt off the slab. One sealer maker says a properly applied penetrating sealer typically protects outdoor concrete for 5 to 10 years and calls it the preferred choice where freezes and deicing salt are a factor.
