Potholed gravel or a cracked lot that holds puddles? We build a concrete lot planned around your drainage, your schedule and your business.
Concrete parking lot building in Redmond means turning dirt, gravel or worn-out paving into a concrete surface for parking, built on a dug-out, packed base and sloped so rain runs off instead of sitting where people park. Done right, it takes years of daily cars with less upkeep than asphalt.
Most lots we're called to are gravel that's gone to potholes, or an old slab that's cracked, sunk in spots and holding water right where people step out of their cars. The price moves with the size of the lot, what has to come out first, how much base work the ground needs, how thick the concrete has to be for what parks on it, and extras like curbs or drains. If there's an old slab in the way, concrete cutting is often where the job starts. The schedule turns on the city's review, the weather and how long you can do without the lot, and your own figure comes from the on-site estimate, once I've seen what's there.
I come out for the estimate myself, so the person pricing your lot is the one who'll be on site when it's built. Our own crew does the work with me running the job, so what you tell me at the estimate doesn't get lost by pour day.
We've been at this since 2013, and I learned a lot of it breaking up old slabs to see why they gave out. Usually it's what's underneath or where the water goes, so that's where I look first before we price anything new.
We're licensed and insured. You don't have to take my word for it, because the state's contractor lookup shows whether a business has an active registration and paid-up workers' comp for its crew. Look us up, then call (425) 285-8618 and I'll come see your lot.
We reply within one business day to set a time, then I come out, walk the lot with you and give you an estimate with no obligation. It helps to have the rough square footage, what's on the ground now and the dates you're aiming for.
The City of Redmond requires a permit and approved plans when a project creates or replaces 2,000 square feet or more of hard surface, and most lots are bigger than that. The city counts more than people expect. Turning dirt or gravel into concrete counts as new hard surface, tearing old paving out down to the base layer underneath counts as replaced, and both fall under the city's stormwater rules once a project is big enough. Even pervious concrete, a mix with open gaps that lets water through, still counts as hard surface. Before we set a date, we find out which office covers your address and what your lot calls for, then tell you plainly who'll handle the permit and the inspections.
The calendar matters as much as the paperwork. Work expected between October 1 and April 30 needs a city-approved wet weather plan for keeping mud and silt from washing off the site, and the city says clearing and grading review generally takes 4 to 5 weeks, so a lot you want open by spring needs planning well ahead of it. We're based in Redmond and build lots the same way in Kirkland, Bellevue and the cities around them, and if yours isn't on our pages, just ask. Around here we mostly see gravel lots behind small shops that turned to soup after a few wet winters, and older lots where the water was never given anywhere to go.
Across the US, building a concrete parking lot usually costs about $5 to $10 per square foot, and that's a national guide price for the work, not ours. Your Redmond figure comes from the on-site estimate, once I've seen what's there now and what the ground needs. Call (425) 285-8618 to set one up.
It usually is if you'll keep the lot a long time. Asphalt typically costs 20 to 40 percent less up front, but concrete lasts about 25 to 40 years against 15 to 25 for asphalt, and over 30 years or more concrete often matches or beats it on total cost. If you expect to sell or redo the property sooner, asphalt can be the smarter spend.
Building a parking lot usually takes about 2 to 4 weeks, depending on its size, how many features it has and the site itself. Bad weather or a material shortage can stretch that, so leave some slack around your business plans. The city's review time, covered above, comes before any of it.
Plan on keeping cars off for at least 7 days while the concrete cures, which is the slow hardening it does after the pour. It keeps gaining strength until about 28 days, so close the lot or arrange other parking for at least that first week. If you can't close everything at once, building in sections helps.
Hot-poured sealant usually lasts about 3 to 8 years in concrete pavement joints, silicone about 8 to 10, and preformed seals up to 20. Preformed costs the most and hot-poured the least, so the choice comes down to paying more now or resealing more often. We'll go over which fits your lot at the estimate.
