Cost breakdown by service type
Most common wood species restored in Portland
Portland’s housing stock includes Douglas fir in many older homes, red oak across numerous craftsman and mid-century properties, and growing use of white oak, maple, hickory, and engineered products in remodels. These are field observations, not measured Portland-wide shares. Our open 10-project sample publishes the underlying records and limitations for the counts we can substantiate.
Hardwood installation costs
For new hardwood installation, total investment depends heavily on lumber grade, wood species, subfloor preparation, and whether the material is site-finished or prefinished. In Portland, a complete turnkey hardwood installation typically ranges from $8.50 to $14.00+ per square foot (materials and professional labor combined).
Refinishing vs. New Installation: Refinishing your existing hardwood ($5.40 to $6.50 / sq. ft.) is 40% to 60% more cost-effective than installing brand new hardwood floors ($8.50 to $14.00+ / sq. ft.). Keeping your original wood preserves seasoned old-growth lumber and eliminates the costs of demolition, disposal, new milled lumber, and subfloor reconstruction.
Installation cost breakdown (labor and materials)
Note: Portland’s wet Pacific Northwest climate requires a strict 5–7 day indoor climate acclimation period for solid hardwood prior to fastening to prevent seasonal cupping and gapping.
Hardwood floor repair costs
Repair pricing doesn't fit a clean per-square-foot number the way refinishing and installation do, because the scope varies so much: replacing three water-damaged boards under a window is a different job than lacing in a full hallway after a pipe leak. We quote repair work per job, after seeing the damage in person, based on:
- Number of boards affected and whether matching stock is available or needs to be sourced
- Whether the subfloor underneath is sound or also needs repair
- How closely the repaired section needs to match the surrounding floor's stain and finish
- Access (furniture, flooring layers, whether the room needs to be cleared)
If you're comparing repair quotes, ask what's included in each: board matching and stain blending, subfloor inspection, and finish coats on the repaired area versus the whole room. See our hardwood floor repair guide for what a typical repair visit covers.
Cost by wood species
Species affects both material cost and labor time. Denser woods like hard maple and hickory sand more slowly than Douglas fir or red oak, which can add labor time to a refinishing job; softer species like fir show wear (and repair) more easily but sand faster. Reclaimed or historic material, common in Portland's older Craftsman homes, often needs a gentler sanding sequence to avoid over-thinning boards that have already been refinished several times. See our Douglas fir and historic floor restoration guide for what that looks like in practice.
How to use this guide
Compare written scopes, not price alone: sanding sequence, repair allowances, containment, stain, finish product and coat count, trim work, furniture, and cure timing can explain a large difference between bids. See our claim sources and verification notes.
