Asphalt Sealcoating in Spokane, WA
Summit Surface Partners is a full-service asphalt sealcoating contractor in Spokane, WA. We seal commercial parking lots, HOA driveways, retail centers, and municipal lots across Spokane County — using our own Pitch Black® polymer-reinforced sealer manufactured in Kalispell, Montana, so every Spokane job ships with a fresh, traceable batch instead of commodity sealer that's been sitting on a tanker for weeks.
Why a local crew matters in Spokane
Spokane has a strong existing contractor base, which means we don't try to displace local crews — we extend their capacity on jobs that overflow their schedule, on Pitch Black bulk supply where national freight doesn't pencil, and on dry ice and brine specialties where the local market is thin. The honest pitch in Spokane isn't 'use us instead' — it's 'use us when your usual answer can't fit the job.'
On the wholesale side, Spokane is our highest-volume out-of-MT delivery lane. We can run a tanker over Lookout Pass to a Spokane Valley yard inside 24 hours, which beats the typical Salt Lake or Tacoma freight schedule on bulk Pitch Black orders by 3–7 days.

The Spokane asphalt sealcoating schedule
Spokane thaws on roughly the Coeur d'Alene cadence. Walks in March, crack seal in April as overnight lows allow.
Prime sealcoat window is mid-May through early September in Spokane. Healthcare and student-housing properties book the prime June–early-August slots first.
Final crack seal pass, striping touch-ups, and brine staging before the first November snow event.
Spokane gets more winter than national contractors typically expect. Documented brine and salt application logs for every storm event are standard on commercial accounts.
Our asphalt sealcoating process
Site Walk & Scope
We measure the lot, log every crack and pothole, photograph problem zones, and identify drainage or substrate issues that need to be addressed before sealer goes down. You get a written scope with line-item pricing.
Crack Seal + Sealcoat Application
Hot-pour rubberized crack sealant goes in first. Two-coat sealcoat application follows once temps and humidity are right. Crews barricade, sequence work in phases, and post reopen times so tenants and customers aren't surprised.
Restripe + Documented Handoff
ADA-compliant striping, fire-lane re-paint, and accessible-parking markings finish the job. You get a closeout packet — before/after photos, application logs, batch numbers, and a recommended re-seal date.
