Cojo provides asphalt paving services across Lake Oswego, OR -- new paving, repair, driveway work, sealcoating, and parking lot striping. We dispatch crews from our Hood River HQ to Clackamas County for projects from Lakewood and Westlake premium-residential driveways to First Addition commercial pads. Lake Oswego property owners typically work to a higher finish standard than other Oregon markets -- aesthetics matter as much as structural performance -- and we bid accordingly. For pricing context across Oregon, see our Oregon paving cost guide.
Services We Offer in Lake Oswego
Five service categories cover most Lake Oswego asphalt work.
- New paving: driveways, parking lots, private roads, HOA shared drives. Includes excavation, base prep, hot-mix placement, and finish rolling to a clean finish appropriate for premium-residential properties.
- Repair and patching: pothole repair, crack sealing, alligator-crack patching, edge-spall repair, full-depth section replacement. We use saw-cut edges and tight joint work where aesthetics matter.
- Driveway work: new asphalt driveways, resurfacing, repair, and apron coordination with Lake Oswego and Clackamas County permitting.
- Sealcoating: maintenance sealcoat application. See Lake Oswego sealcoating for cadence and spec detail.
- Parking lot striping: layout design, restriping, ADA-compliant accessible stalls and ramps. See Lake Oswego parking lot striping for layout standards.
A typical residential driveway project bundles new paving or resurfacing with sealcoating once the new mat cures. A typical commercial project bundles paving with striping on the same mobilization.
Lake Oswego Conditions That Drive Scope
Lake Oswego sits on the south side of Portland along the Tualatin River and Oswego Lake. Annual rainfall runs 40 to 45 inches, summers are warm and dry, and winters bring 15 to 25 freeze-thaw cycles. The soils run from Cascade and Aloha silty clay loam in the flatter areas to Saum and Goble on the hillsides above Oswego Lake.
Site conditions worth flagging for Lake Oswego property owners:
- Hillside driveways: lots above Oswego Lake and in Westlake have grade changes that affect drainage and require specific base details. A driveway that slopes toward the garage needs catch-basin and trench-drain work as part of any new paving scope.
- Premium-residential finish standards: clean edges, saw-cut scope boundaries, neat joint details, and tidy site management matter on Lake Oswego properties. We bid accordingly.
- Mature-tree root systems: First Addition and Lakewood neighborhoods have decades-old trees with surface roots that can buckle existing pavement. Root pruning or root-resistant barrier installation is sometimes part of the scope.
- HOA aesthetic standards: several Lake Oswego HOAs have specific finish requirements that should be referenced in the bid.
- Clackamas County and Lake Oswego stormwater rules: projects near the lake or in mapped flood plains can trigger detention or treatment work.
A real contractor brings these conditions up during the site walk. A templated quote rarely does.
Industry Baseline Range
| Project Type | Cost Per Sq Ft | Typical Total Cost |
|---|---|---|
| Residential driveway (2-car) | $2.50 to $12.00 | $3,000 to $18,000+ |
| Premium driveway (3-car or custom) | $3.00 to $15.00 | $8,000 to $30,000+ |
| Driveway resurfacing (overlay) | $1.50 to $5.00 | $1,500 to $8,000+ |
| Small commercial lot | $2.00 to $10.00 | $8,000 to $60,000+ |
| Mill-and-overlay (commercial) | $3.00 to $7.00 | $30,000 to $150,000+ |
Current Market Reality
The baseline assumes a flat lot, sound aggregate base, easy access, and no drainage or ADA upgrades. Most Lake Oswego properties have at least one complicating condition: hillside drainage, tree-root remediation, HOA aesthetic standards, or premium-residential finish work that requires more careful crew time than a standard suburban driveway. Bids in Lake Oswego skew toward the upper end of the per-square-foot range because the finish standard is higher and the site conditions are more complex. A real bid lines these conditions out as separate items rather than burying them in a blanket rate. For broader Oregon pricing context, see our Oregon paving cost guide.
Scheduling Around Lake Oswego Operations
Asphalt placement needs ambient temperatures above 50 degrees F and dry conditions. In Lake Oswego that puts the working window at roughly May through mid-October. Sealcoating wants 60 degrees F overnight, which compresses placement to mid-May through mid-September.
For residential driveways, we typically schedule a single-day pour with two to three days of cure before vehicles return. For HOA shared-drive work, we sequence by household with notifications coordinated through the HOA management. For commercial work in First Addition and along Boones Ferry Road, we sequence around tenant operations: overnight pours where Lake Oswego permitting allows, weekend phasing for larger lots, lane-by-lane closures for drive aisles. We hand the property owner or manager a phase map, cure-time schedule, and back-in-service date per zone.
Why Property Owners Choose Cojo
Cojo has been a licensed Oregon contractor since 2009 (CCB licensed and insured). We run our own crews and equipment rather than subbing out, which keeps one accountable party on schedule, change orders, warranty, and the finish standard a Lake Oswego property owner expects. Our Hood River HQ dispatches to Lake Oswego in about 90 minutes via I-84 and I-205, and we treat mobilization as an honest line item.

Permits, Inspections, and Documentation
Lake Oswego and Clackamas County permitting varies by scope. New driveways with apron work in the public right-of-way typically need a city apron permit. Commercial work that materially changes impervious area or drainage triggers a stormwater review and may need a sediment-and-erosion control plan, especially for sites near Oswego Lake, Springbrook Creek, or the Tualatin River. Several Lake Oswego HOAs require advance written notice and aesthetic-spec compliance; we coordinate that as part of the project scope. Tree-related work near surface roots may require an arborist consultation before we touch the area, and we factor that into scheduling.
For homeowners and commercial property managers alike, we provide a closeout package at project end: as-built drawings if drainage was modified, photographic records of base prep and sub-base before placement, structural-section specs, sealcoat and striping spec sheets, finish-detail photographs, and a one-page warranty summary. That documentation supports refinance, sale, and insurance-renewal needs. Our standard package goes out by email within five business days of substantial completion.
Getting a Bid for a Lake Oswego Project
For a 2026 driveway, HOA shared-drive, or commercial project, schedule a site walk. We'll walk the site, core where the base looks suspect, scope each zone, and hand you a phased bid with mobilization, sequencing, finish details, and warranty terms in writing.
Residential bids in Lakewood, First Addition, Westlake, Country Club, and Mountain Park typically come back within 48 to 72 hours of the site walk. Commercial work with drainage or HOA coordination can run a week to ten days. Whatever the project, the bid arrives lined out by treatment, with the finish standards and conditions the property already implies built into the scope.
