Cojo runs sealcoating crews into the 97005 zip -- central Beaverton, including downtown, Cedar Hills, and the older mixed-use neighborhoods east of Murray. The local work is heavy on apartment-complex lots, downtown mixed-use redevelopment surfaces, and the small commercial lots that line Canyon Road, Cedar Hills Boulevard, and the adjacent corridor streets. Pricing depends on square footage, prep needs, and traffic schedule, but most local jobs land within the published baseline range below.
Sealcoating in Central Beaverton -- The Local Picture
97005 covers some of the oldest asphalt in the Portland metro -- downtown Beaverton lots and Cedar Hills retail surfaces dating to the 1970s and 1980s that have been sealed and re-sealed enough times that the layered seal coat is its own structural element. Newer apartment redevelopment along Canyon Road and the central grid has a younger surface profile, mostly in the 5 to 15 year range, which is the prime sealcoat window.
The summer climate in central Beaverton is the standard valley pattern: 75 to 95 degrees F daytime, low humidity, dependable dry stretches from late June through early September. That's a wide enough window to schedule the full 97005 customer base, but the contractor-density in the Portland metro means peak-season scheduling fills up by April. Property managers who want a July install need to be on the calendar by March.
Beaverton city and Washington County stormwater rules apply to anything that affects drainage. Sealcoating itself isn't a stormwater event, but if you're pairing a sealcoat with crack-fill and re-stripe, the project documentation should call out any drainage impact. Property managers handling federal funding (HUD apartment programs) or commercial lease maintenance often need documented work scopes; we provide those by default.
Sealcoat Types We Apply in 97005
The three product classes that fit the local work:
- Asphalt-emulsion sealer -- the standard for residential and most apartment-complex lots. Clean-smelling, fast cure, good wear under typical Portland-metro traffic.
- Polymer-modified emulsion -- the upgrade product for high-visibility commercial lots and HOA roads that need 3 to 4 years of clean appearance. More flexible under freeze-thaw, slightly more expensive per gallon.
- Refined coal-tar emulsion -- the heavy-duty product for fleet yards and high-fuel-exposure surfaces. Air quality regulation has restricted coal-tar use in some metro jurisdictions; we confirm allowability before spec.
The right product depends on the surface age, the traffic mix, and the cycle the property manager is targeting. We walk the lot, check the existing condition, and recommend a product the surface can actually accept and the budget can support.

Current Market Reality
The published ranges assume a clean surface, no major crack-fill prep, daytime mobilization, and a single visit. Beaverton apartment complexes that need night work to avoid resident disruption run higher. Commercial lots with significant oil-spot contamination need degreasing and priming before sealcoat, which adds material and labor cost. Sealer material prices have moved 20 to 40 percent over recent seasons depending on product class, and quotes older than 30 to 60 days should be re-validated.
Why Central Beaverton Lots Wear Faster Than Suburban Lots
Three things drive faster wear in 97005:
Traffic density. Canyon Road and Cedar Hills Boulevard carry significantly more vehicle counts per stall than suburban lots in Sherwood or Cornelius. Every car movement is a small abrasion event on the seal coat.
Tree canopy and shade. Central Beaverton has mature street tree canopy, which keeps lots damp longer after rain events. A lot that stays wet 36 hours after a storm rather than 12 hours degrades faster and supports more moss and lichen growth on north-facing edges.
Salt and de-ice product. When winter storms hit and de-icing salts get tracked onto lots, the salt attacks the seal coat and the binder beneath it. Lots near major arterials see more of this than back-lot residential surfaces.
The combination means a Beaverton commercial lot on a 3-year seal cycle often needs to drop to a 2-year cycle, or upgrade to polymer-modified product to hold the 3-year interval. For deeper context on commercial scope, see our commercial sealcoating Beaverton guide and parking lot sealcoating cost guide.
Scheduling and the Beaverton Sealcoat Window
Sealer chemistry requires:
- Ambient temperature above 50 degrees F and rising
- Surface temperature above 55 degrees F
- No rain for at least 24 hours after application
- 24 to 48 hours of cure before traffic
In central Beaverton, the dependable window is late May through mid-October. Shoulder days in mid-May and late October work in dry years and don't in wet ones. We track 7-day forecasts and pull weather buffers into every quote. For the full timing breakdown, see our best time to sealcoat in the Willamette Valley guide. For step-by-step process detail, our sealcoating process steps article walks the full sequence.
Picking a Sealcoating Contractor in 97005
What to verify:
- Oregon CCB license -- required, easy to check.
- Product spec on the quote -- the sealer type and application rate should be on paper.
- Crack-fill plan -- cracks wider than 1/8 inch need to be filled before sealcoat.
- Cure-and-traffic plan -- a commercial lot that has to reopen in 12 hours needs a fast-cure additive on the quote.
- Insurance -- liability and workers' comp.
- Re-striping coordinated -- sealing a striped lot without coordinating the re-stripe looks half-done immediately.
