Who We Are

A Seattle crew
built for the PNW.

Interstate Asphalt of Washington is a Seattle-based team that lives and paves in the Pacific Northwest. Residential driveways, commercial parking lots, chip seal on long rural drives, sealcoat maintenance, and the kind of repairs that keep a lot honest for another decade.

PNW ground is tough on pavement. Saturated winters soften the subgrade. Old Douglas firs and cedars heave drives from below. Marine air near the Sound eats at edges, and elevation up past North Bend and Snoqualmie puts pavement through proper freeze-thaw. Pavement here fails from underneath first, so we spec the base and the drainage to match. Not the cheapest way. The right way.

Fresh sealcoat applied to an asphalt driveway

Sealcoating

Sunscreen for your asphalt. A coat every 2 to 3 years blocks UV, slows oxidation, and stops hairline cracks before they turn into the expensive kind.

Asphalt resurfacing with a double-drum roller

Asphalt Resurfacing

If the base underneath is still solid, a new overlay buys you another ten to fifteen years for a fraction of a full tear-out. We will tell you straight whether it is the right call.

Our Process

Four steps,
zero surprises.

Paving shouldn't feel like a guessing game. Here's exactly how a job runs from the first call to the final walkthrough. No scope creep, no hidden fees, no sales pitch.

01
Site walk & written quote
We come out, measure the area, check subgrade and drainage, and hand you a written estimate, usually the same day. No charge. No pressure to book.
02
Prep the site
Once you say go, we lock the date, order the mix, mark utilities, and clear the footprint. You'll know the crew arrival window to the hour.
03
Pave & roll
Base compacted, edge cuts sharp, hot mix laid and rolled in the right order. No subs, no hand-offs, the same faces on day one finish on the last day.
04
Final inspection
We walk the finished surface with you, answer cure-time questions, and leave you with our number for anything that comes up later.

Word Of Mouth

What our Seattle
customers say.

Interstate paved our driveway up in Kirkland last month and I couldn't be happier. The crew walked the site with me, wrote up an honest quote that same afternoon, and showed up on the morning they said they would. Job was done in a day and a half and the edges are sharp. No upselling, no nonsense. These folks know their trade.

We have a long rural drive out past Carnation and the Interstate team talked us through chip seal as an alternative to full pavement. Saved us a small fortune and it looks great. Held up through a wet winter just fine. Crew was polite, cleaned up after themselves, and the owner personally checked the finished job before leaving.

Had our parking lot repaved over a weekend so we didn't lose business. The Interstate crew worked around our hours, communicated every step, and the finished lot looks brand new. Fair price, clean crew, no surprise invoices. Already have them lined up for sealcoating next spring.
