What does it take to build a concrete patio in Kirkland?
Concrete patio construction in Kirkland means we dig out the ground, pack a firm base, set forms that slope away from your house, then pour and texture a slab you can walk on wet without sliding around.
Most people call because the old patio is cracked, sinking or holding water, or because the back of the house is a patch of mud nobody uses. The price moves with the size, how much dirt has to come out to reach firm ground, whether there's an old slab to break up and haul away, how easy it is to get concrete to the spot, and the finish you pick, from plain broom to decorative concrete. The schedule turns on whether your lot needs anything from the city first and on the weather for pour day, and I give you your own figure in a written estimate after I've seen the site.
How do you know it's time for a new patio?
Cracks that keep spreading
Cracks that open wider every year, or edges that tilt, usually mean the ground under the slab moved or the old base was never packed. Patching buys you a season or two, but the slab keeps moving until the ground under it is dealt with.
Water pooling by the house
If puddles sit on the patio or run back toward your siding after a storm, the slab was poured flat or sloped the wrong way. Waiting lets that water soak into the ground beside your foundation, which is a bigger bill than a patio.
One side sinking lower
A step down where the patio meets the house, or a corner that rocks underfoot, usually means soft fill underneath that settled. It turns into a trip hazard first, and the slab tends to crack across the low spot later.
How we build a concrete patio
Before we set a single form, I ask where you want the water to go, because the slope we build in decides whether rain runs into the lawn or back against your house. Then we dig out the soft dirt down to the subgrade, the ground the slab actually sits on, and pack the base evenly so there are no wet or soft spots waiting to settle. We set the forms to that slope, lay in mesh or rebar where the job calls for it so the steel holds the slab together if it cracks, and have all of it done before the truck shows up, since stalling once the concrete arrives makes a weaker slab. Then we pour, smooth it and put the texture on top. If the budget gets tight, the base is the one place I won't cut, because nobody sees it on day one and a fancy top on a soft base just sinks in a nicer pattern.
A patio rarely stands alone. If you want a stone or brick pattern pressed into the top, that's our stamped concrete services, and if you need a path from the patio to the driveway or side gate, we handle concrete sidewalk building and can often form it along with the patio.
Broom finish
This is the one I steer most people toward, because the brushed texture gives your feet something to grab when the patio is wet. It suits patios by a back door, a grill or anywhere kids run, and it costs less than decorative work.
Color, exposed aggregate or stamped
These suit a patio that's meant to be looked at as much as walked on, and each one takes its own steps and practice to get right. Before you pick one, we'll show you work we've done in that finish and talk about grip, since a broom finish is still the safe pick for that.

What happens when you call about a patio in Kirkland?
Here's how a patio job runs from your side, from the first call to the final walk-through, and who you'll be dealing with along the way.
Call or send the form
Call (425) 285-8195 or fill out the form with your address and what you have in mind. We get back to you and set a time for me to come out.
I look at the site
I walk the spot with you, check which city or county office covers your address, and then send a written estimate. You see the price in writing before anyone digs, so there's no guessing what the patio will cost.
We prep, pour and finish
Once you're set, we get the ground and forms ready before the concrete arrives, then pour and finish the slab. Keep cars and toys clear of the path to the backyard that day, because the concrete has to get through it.
Walk the finished patio together
When it's done, we walk the job with you and look at the finish, the joints and where the water runs off. That's the time to ask anything you want to know about your new slab.
Why Kirkland homeowners call Precision Kirkland Concrete for a patio
The owner writes your estimate
I come out to look at your yard and write the estimate myself, and I work on site with our crew when we pour. The person who told you what the job needs is the one watching the base and the forms go in.
Pouring flatwork since 2020
I started this business in Kirkland in 2020, and flatwork like patios, walks, driveways and garage floors is what we're known for. That's six years of learning which shortcuts show up as cracks later.

Your satisfaction, guaranteed. When you're ready, call (425) 285-8195 or send us the details and I'll set a time to come look.
Patios, walks and the rules on Kirkland lots
Before any digging, it helps to know that the city's permit page lists permits for removing or filling more than 50 cubic yards of soil and for work that changes drainage, and its exempt list names sidewalks, decks and driveways, not patios. That list doesn't settle a patio either way, so the city is the place to ask about your own project. Those exemptions also stop at flood hazard, wetland, steep slope, shoreline and other critical areas, and a Parcel Report from the city's Property Search Tool shows whether your lot falls in one. When your patio needs a permit, we can file it for you or help you file it, and we plan the start around the approval and the inspections.
A lot of the backyards we see here have some slope to them, or downspouts that already dump water right where the patio is going, so the drainage question gets settled before the forms go in. We see the same kinds of yards on jobs in Bellevue and Redmond, and we handle them the same way, digging to firm ground and sending the water somewhere it can't hurt.
Questions about concrete patios in Kirkland
Which concrete patio finish is least slippery when it's wet?
A broom finish is the grippiest everyday choice, because the push-broom texture brushed in after floating, the first smoothing pass, leaves fine ridges your shoes catch on. Outdoor slabs also need a slope so water drains off, since a textured slab with standing water is still a wet slab.
How long does a concrete patio last?
One Seattle patio guide lists an average life of 30 to 50 years for concrete, against 25 to 35 years for brick pavers. That's an average for the material, not a promise for any one patio, and the base under yours has a lot to say about where it lands.
Can a concrete patio be poured in cold weather?
Yes, concrete poured in the cold still gains enough strength as long as it's properly mixed, placed and protected. Cold-weather conditions apply once the air falls to, or is expected to fall below, 40°F while the fresh concrete is being protected, so a cold-season pour needs a protection plan. The ground matters too, because concrete shouldn't go onto a cold base.
What city rules affect a patio on my Kirkland lot?
Setbacks, lot coverage and, on bigger projects, drainage review are the rules that usually reach a patio, on top of the permit question covered above. The city says work still has to meet its codes even when no building permit is required, and its Planning division at 425-587-3600 confirms which ones apply to your lot. If your project is already under a city permit or approval, adding or replacing 500 square feet or more of hard surface that water can't soak through also triggers a drainage review.
How much does a concrete patio cost in Kirkland?
There's no honest number until I've seen your yard, because size, digging, tearing out an old slab and the finish move the price more than anything else. A plain broom finish on open ground the truck can reach sits at the low end, and a decorative top behind the house where concrete has to be moved in by hand sits higher. The written estimate lays that out for your patio.
What is the best way to keep a new concrete patio from cracking?
Nobody can promise concrete won't crack, but a packed base and control joints cut on time keep cracks small and in places we picked. Control joints are shallow grooves cut into the slab so it cracks along a straight line inside the groove instead of across the middle. Cut them late or skip them, and the slab picks its own spots.
Other concrete work that goes with a patio
Stamped concrete services
Pick this when you want the patio pressed with a stone, brick or tile pattern, so the slab looks like pavers without the gaps weeds love.
Concrete sidewalk building
Add a walk when the patio needs a firm path to the driveway or side gate, built on the same packed base so both sit level.
