Asphalt Crack Repair in Tigard, Oregon: Diagnosis & Fix

Asphalt crack repair in Tigard starts with diagnosis, not a bucket of filler. The right fix depends on the crack: thermal and shrinkage cracks get routed and sealed, while alligator (fatigue) cracking signals base failure that needs full-depth repair. Tigard sits in the Tualatin Valley on Washington County clay soils that hold winter water, and its busy retail and office lots along Hwy 99W and Hwy 217 take constant traffic that works cracks hard. Seal working cracks before the rain, and call structural cracking what it is: a repair, not a seal.
Every crack tells you something, and the mistake is treating them all the same. A single straight crack across a Tigard driveway is a different problem than a web of connected cracks in a busy drive aisle at a retail center.

Tigard combines wet Tualatin Valley soils with heavy commercial traffic, and that pairing is hard on asphalt. Washington County's silt and clay hold moisture against the base through the rainy season, while constant turning and braking at retail and office lots concentrate stress.
The repair has to match the crack. Sealing and filling sound the same but are not, and neither fixes a failed base.
| Crack type | Right repair |
|---|---|
| Working thermal/transverse crack | Rout and seal with hot rubberized sealant |
| Non-working hairline or shrinkage crack | Crack fill to block water |
| Block cracking from oxidation | Seal worst cracks, then sealcoat the surface |
| Alligator (fatigue) cracking | Full-depth patch — rebuild the base |
Crack work is one of the cheapest ways to extend pavement life — far cheaper than the resurfacing you will face if water keeps reaching the base, which matters on a high-traffic retail lot you cannot easily close.
Industry Baseline Range: rout-and-seal crack repair generally runs in the range of $1 to $3 per linear foot, while full-depth repair of fatigued areas runs $4 to $9 per square foot+. These are industry baseline ranges for planning only — actual pricing depends on lot size, access, condition, and current market conditions. Get a site-specific quote.
In Washington County, the best time to seal cracks is before the wet season so water cannot sit in them all winter. Oregon's May-to-October paving window fills up quickly and metro crews book out early, so getting crack work scheduled ahead of the rain — and around your retail hours — is both cheaper and more effective.
We diagnose first, then route and seal working cracks, fill the static ones, and flag any alligatoring for full-depth repair rather than pretending a seal will hold it.

If you have cracking on a Tigard driveway or commercial lot, seal it before winter drives water into the base. See our asphalt repair services and our Tigard alligator cracking repair page, then request an assessment.
