Driveway repair in Sellwood is a different conversation than driveway installation. Most Sellwood driveways are 40 to 90 years old, sitting on bases that were laid when 4-inch base depth was standard and when nobody planned for the mature canopy that now sits over half the neighborhood. The repair question on a typical Sellwood drive comes down to one decision tree: crack-seal-and-overlay versus full reconstruct. Get that decision right and you spend $2,500 to $7,500 and add 10 to 15 years of life. Get it wrong and you spend overlay money on a base that fails inside 3 years, then pay reconstruct money on top of that.
When Crack-Seal-and-Overlay Is The Right Call
Crack-seal-and-overlay works when the existing driveway has surface deterioration but the base is still structurally sound. Signs your driveway is overlay-eligible: cracks under a quarter inch wide, no alligator (spider-web) patterning, no depressions or dips you can feel walking the surface, no visible base failure at the edges, no standing water after rain. Surface oxidation, raveling, minor crack patterns running with the original score lines -- all overlay territory.
Our standard overlay prep on a Sellwood driveway is full surface clean and crack-seal of any opening over an eighth of an inch, hot-mix infrared patch for any localized failures, tack coat across the prepared surface, then 1.5 to 2 inches of new hot-mix asphalt rolled to full compaction. On canopy-affected jobs we add root-mitigation work before the overlay -- typically root pruning where ISA-arborist-approved and a geotextile interlayer to slow root return.
When Full Reconstruct Is The Right Call
Reconstruct is the answer when the base has failed. Signs your driveway needs reconstruct: alligator cracking covering more than 30 percent of the surface, depressions or dips you can feel walking, tree-root heave where the asphalt has been lifted clear of original grade, edges crumbling because the base material has migrated, standing water in low spots after rain, or visible pothole formation. None of those are surface-treatment problems and none of them respond to overlay.
Standard Sellwood reconstruct: full demo of existing asphalt and base, root pruning and Urban Forestry coordination if canopy-adjacent, geotextile fabric over native, 6 to 8 inches of 3/4-minus compacted base in two lifts, and 2.5 to 3 inches of hot-mix asphalt. We proof-roll the base with a loaded vehicle before paving. The job is 1 to 2 days on a standard residential driveway, 2 to 3 days on alley-access jobs that need apron coordination.
Tree-Root Heave: The Sellwood Specialty
Mature canopy plus pre-war driveway bases equals a lot of tree-root heave. Sellwood sees more root-heave repair calls than most Portland neighborhoods. The fix depends on the tree, the root size, the heave magnitude, and whether the tree is a street tree (City of Portland Urban Forestry jurisdiction) or a private-property tree.
On heave of less than an inch with a healthy tree, root pruning plus localized reconstruct of the affected section is the standard fix. On heave over 2 inches or with structural-root involvement, the options narrow to full reconstruct with arborist-approved root work or flexible-base alternatives (permeable pavers or rubberized surface in the affected zone). We coordinate with City of Portland Urban Forestry on any street-tree-adjacent work. Skipping the arborist sign-off and cutting structural roots will kill the tree, void any tree-replacement obligation, and put you on the hook for damage costs.

| Crack-seal-and-overlay, 2-car drive | $3 to $7 | $2,500 to $7,500 |
| Full reconstruct, 1-car drive | $7 to $14 | $4,500 to $11,000 |
| Full reconstruct, 2-car drive | $7 to $14 | $6,000 to $15,000 |
| Root-heave repair, localized | $8 to $16 | $1,500 to $6,000 |
Current Market Reality
Real 2026 Sellwood repair prices run above baseline. Hot-mix index, fuel, labor, and asphalt-demolition disposal are up since 2022. Arborist-coordination on canopy-affected reconstruct adds $400 to $1,500 to a typical job. For broader cost context, see our asphalt paving cost in Oregon guide. A real number takes a site visit -- nobody can phone-quote a Sellwood driveway repair without walking the surface and assessing the base.
How To Hire For Sellwood Repair Work
Three questions for every Sellwood bidder. First: overlay or reconstruct -- and what specific signals on my driveway drove that call? A bidder who answers without inspecting the edges, looking for alligator patterns, and walking for depressions hasn't done the assessment. Second: how are you handling tree-root mitigation? Anything within 10 feet of a mature canopy tree needs an answer. Third: are you coordinating with Urban Forestry if any of the affected trees are street trees? Skipping that coordination is a code violation and a potential liability.
