Our Story

A Pacific Northwest
paving family.

We are Interstate Asphalt of Washington, a multi-generation, family-run paving crew based in Seattle. We pave driveways, parking lots, and chip seal lanes across King, Snohomish, and Pierce counties. One rule has held the whole time: every job is the foundation of our reputation. Right now we're running $1,000 off any paving project — ask when you book.

Where We Started

Pacific Northwest grown,
built on handshakes.

Interstate Asphalt of Washington was built on a simple rule: every job is the foundation of our reputation. This is a family operation, crew members who grew up in the trade, passed the shovel and the rake down the line, and have spent decades paving around Puget Sound. We've seen every kind of driveway, every kind of parking lot, and every kind of shortcut a cheaper crew will try to take. We refuse to run the job any way but the right way.

PNW pavement fails from the bottom up. Wet winters saturate the subgrade, saturated clay turns to pudding, and the freeze-thaw cycles in higher elevations like North Bend and Snoqualmie pry cracks open wider every spring. Douglas fir roots heave edges on older properties. Moss grows into any hairline crack you leave unsealed. Near the Sound, salt air eats binder. If the base isn't deep enough, if compaction is lazy, if drainage isn't planned, you will see it in three years: alligator cracking, standing water, potholes walking in from the edges.

We spec every job to outlast that. Deeper base sections on saturated Seattle soil. Positive grade to daylight water, not to the garage door. Aggregate sized for the loads you actually run on it. What you get when you hire us is straight talk on what your surface actually needs, a written number the same day, and a crew that stays tidy, shows up on time, and finishes what it starts.

Why Folks Pick Us

The difference,
in plain English.

01

Owner-Run

We answer the phone. We walk your site. We are on the crew laying the mix. There is no middleman taking a cut on the quote or sending someone you haven't met to finish the job.

02

Pacific Northwest Specs

Saturated clay, moss, freeze-thaw at elevation, marine salt air near the Sound, root heave from big firs. Our base depths and mix choices are built around how pavement actually fails here, not a spec sheet written for Arizona.

03

Honest Conversations

If you don't need a new mat and an overlay will do, we'll tell you. If you need full tear-out, we'll tell you that too. Upselling is the fastest way to lose a customer.

04

Our Crew, Every Time

We don't sub out the heavy work. The people who quote you are the same ones laying the mix, pulling the edges straight, and walking the finished surface with you.

05

On Time, On Word

Booked a Tuesday morning? The trucks are at your curb Tuesday morning. If weather forces a move, you hear about it the day before, not the day of.

06

Base Comes First

Most pavement failure starts below the surface. Grading, base depth, compaction, that's where we spend the extra time, because that's what decides whether your surface lasts three years or thirty.

07

Written Quotes

The number on the estimate is the number on the invoice. No day-of surprises. If anything changes mid-job, we stop and talk to you before we touch another foot of ground.

08

Clean Jobsites

We protect your lawn, sweep our edges, pick up every piece of gear, and leave the property cleaner than we found it. You shouldn't have to clean up after the people you paid.
