Sealcoating Cost in Portland, OR (2026 Prices)

What Does Driveway Sealcoating Cost in Portland?

Industry sources have historically reported baseline ranges of $150 to $500 for residential driveway sealcoating in Portland-area communities, with the average two-car driveway falling around $200 to $350, though actual costs vary widely and may be significantly higher. Portland pricing runs slightly above the Oregon state average due to higher labor costs, urban traffic logistics, and the city's dense residential layout that can complicate equipment access.

Whether you live in a Craftsman bungalow in Southeast Portland or a newer subdivision in Happy Valley adjacent areas, understanding what drives the price helps you budget accurately and avoid overpaying.

Portland Driveway Sealcoating Prices by Size

The figures below reflect published industry averages and historical baseline data. Current market pricing varies significantly based on your property's specific conditions. Actual quotes may fall well outside these ranges — in many cases 2 to 3 times higher for complex projects.

Driveway Size	Square Footage	Industry Baseline Range
Single-car	200–400 sq ft	$150–$225
Two-car standard	400–700 sq ft	$200–$350
Large residential	700–1,200 sq ft	$300–$500
Extra-large/circular	1,200–2,000 sq ft	$450–$750

These ranges assume the driveway is in fair to good condition. Surfaces with extensive cracking, oil stains, or base failure require additional prep work that increases the total cost.

Factors That Affect Cost in Portland

Driveway Size and Shape

Square footage is the single biggest cost driver. A simple rectangular driveway is cheaper per square foot than a curved or irregularly shaped surface because straight runs allow faster application with less edge work.

Surface Condition

Cracks need to be filled before sealcoat is applied. Minor hairline cracking is typically included in the base price. Driveways with moderate to heavy cracking — common in Portland's older Eastside neighborhoods — may add $50 to $150 for hot-pour crack filling.

Slope and Access

Portland's West Hills, Council Crest, and parts of SW Portland have steep driveways that require more labor time and careful material application to prevent pooling and runoff. Steep driveways can cost 15 to 25 percent more than flat surfaces.

Number of Coats

Professional sealcoating should always include two coats. Some contractors quote single-coat pricing to appear cheaper, but a single coat provides minimal protection. Always confirm two-coat application is included in your quote.

Seasonal Timing

Portland's sealcoating season runs from late June through September. Booking in early spring for a summer application often secures better pricing, while last-minute September bookings may carry a premium as contractors rush to finish before fall rain arrives.

Regional Pricing Variation

Sealcoating prices vary across the Portland metro area and surrounding communities. Factors that drive regional variation include local labor costs, contractor density, typical driveway sizes, terrain, and distance from major contractor hubs. Communities with steeper terrain or larger average lot sizes tend to see higher baseline pricing, while areas with flat terrain and dense neighborhoods may benefit from more efficient contractor routing. Premium neighborhoods with larger properties and higher service expectations also tend to see elevated pricing. Your actual quote will depend on your specific property conditions rather than regional averages.

What Your Contractor Cannot See Until Work Begins

Even the most experienced contractor cannot fully assess your driveway from the surface. Once work begins, the following hidden conditions frequently change the scope and cost of a sealcoating project:

• Subsurface drainage issues — Water may be flowing beneath the asphalt, undermining the base in ways invisible from above, especially in Portland's rainy climate.
• Base deterioration — The gravel or aggregate base under the asphalt may have shifted, settled, or washed out over time.
• Oil saturation depth — Surface oil stains may have penetrated deeper than expected, preventing proper sealcoat adhesion.
• Crack depth and root intrusion — What looks like a hairline crack on the surface may extend inches deep, sometimes with tree root intrusion widening the damage — common in Portland's tree-lined neighborhoods.
• Previous patch work — Old patches and repairs may not bond well with new sealcoat, requiring removal or additional preparation.
• Slope drainage patterns — Water runoff paths may have eroded the asphalt edge or base in ways not visible until material is moved, particularly on West Hills properties.
• Utility conflicts — Buried utility lines, valve boxes, or drainage infrastructure near or under the driveway can complicate the project.
• Soil composition surprises — Portland's mix of clay-heavy soils and volcanic substrate can affect base stability in unexpected ways.

These discoveries are a normal part of asphalt work and are one reason actual project costs frequently exceed initial baseline estimates.

When Sealcoating Costs More (and Less)

Prices go up:

• July through August — peak demand, full schedules
• Driveways with heavy cracking or oil damage
• Steep or hard-to-access properties
• Small jobs in remote neighborhoods with no nearby route efficiency

Prices go down:

• Early season booking (May–June quotes for July work)
• Bundling with neighbors — contractors offer discounts when they can seal multiple driveways on the same street
• Flat, well-maintained surfaces that need minimal prep
• Larger driveways — the per-square-foot cost drops as size increases

The ROI of Sealcoating Your Portland Driveway

Based on industry averages, replacing an asphalt driveway in Portland costs $4,000 to $10,000 depending on size. Sealcoating every 2 to 3 years at an industry baseline of $200 to $350 per application extends the life of your asphalt by 10 to 15 years. Over a 20-year period, a homeowner who sealcoats regularly spends roughly $1,500 to $2,500 on maintenance based on industry averages — compared to $8,000 or more for a full replacement.

That represents significant savings by simply maintaining what you already have. Actual costs will depend on your driveway's specific condition and the scope of work required at each application. For more on how much to sealcoat a driveway in Oregon, see our detailed breakdown.

Money-Saving Tips for Portland Homeowners

1. Get quotes in spring — Contractors are booking schedules in April and May. Early quotes lock in better rates.
2. Coordinate with neighbors — Two or three driveways on the same block can reduce per-job mobilization costs by 10 to 15 percent.
3. Maintain between sealcoats — Fill small cracks yourself with hardware store crack filler to prevent them from becoming expensive repairs.
4. Do not over-sealcoat — Every 2 to 3 years is sufficient. Annual sealcoating wastes money and can actually cause peeling.
5. Ask about residential sealcoating packages — Some contractors offer multi-year maintenance agreements at a discount.

Frequently Asked Questions

How much does driveway sealcoating cost in Portland, Oregon?

Industry baseline ranges suggest $200 to $350 for a standard two-car driveway, with single-car driveways starting around $150 and larger driveways over 1,000 square feet reaching $500 or more. However, actual costs frequently run higher depending on the specific condition of your driveway and any hidden issues discovered during the project. Pricing typically includes crack filling, cleaning, and two coats of commercial-grade sealer.

Is sealcoating cheaper in Portland suburbs than in the city?

It can be. Communities outside central Portland may see slightly lower baseline pricing due to easier access and lower overhead costs, though premium neighborhoods with larger properties tend to run higher. Your actual quote depends on your specific property.

How often should I sealcoat my driveway in Portland?

Every 2 to 3 years for most Portland driveways. Portland's heavy winter rain and freeze-thaw cycles in the West Hills make regular sealcoating more critical than in drier parts of Oregon.

What is the best time of year to get the lowest sealcoating price in Portland?

Book your quote in April or May for work scheduled in June or early July. This is before peak summer demand drives schedules full, and contractors are more flexible on pricing.

Does sealcoating really save money long-term?

Based on industry averages, a $250 sealcoat every 2 to 3 years protects a driveway that would cost $5,000 to $10,000 to replace. Over 20 years, regular sealcoating represents significant savings compared to neglecting maintenance and replacing the surface. Actual savings depend on your specific situation.
