Concrete Driveway in Hillsboro, Oregon: Cost & Install

Quick Verdict

A concrete driveway in Hillsboro costs more to install than asphalt but pays back with decades of low-maintenance service on Washington County's Tualatin Valley clay. Price is driven by square footage, slab thickness, reinforcement, demolition of any old surface, and access — though Hillsboro's mostly flat lots make access easier than in hillier areas. Because the valley floor is clay-heavy and drains slowly, the base prep and built-in slope matter more than the pour. A standard residential driveway is 4 to 6 inches thick over a compacted base, reinforced for vehicle loads, with control joints and slope so water runs off. Get the base right and the slab outlasts the mortgage.

What a Concrete Driveway Costs in Hillsboro

Concrete driveways are priced per square foot, and the install covers far more than the pour.

Industry Baseline Range: a new concrete driveway in the Hillsboro area typically runs in the range of $9 to $18 per square foot for a standard broom finish, with thicker reinforced slabs and decorative finishes running $14 to $28 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.

What moves the number:

• Demolition. Removing an old driveway adds tear-out, haul-off, and disposal.
• Access. Flat Hillsboro lots are usually easy to reach, but a fenced backyard raises labor.
• Thickness and rebar. Heavier slabs for RVs or multiple vehicles cost more — see concrete driveway thickness.
• Drainage. On flat clay, slope and channel drains are essential.
• Finish. Broom is baseline; exposed aggregate or stamped costs more.

Current Market Reality

Ready-mix and labor prices track material and fuel costs, and Hillsboro's growth keeps crews busy. The reliable pour window in the valley is roughly May to October, so scheduling early gets you the dry days a clean pour and cure need.

The Install Process, Step by Step

A driveway that lasts on Hillsboro clay follows a clear sequence:

1. Excavate and grade. Remove the old surface and topsoil, then cut the sub-grade to the right depth and slope — critical on flat ground.
2. Build and compact the base. Place and compact crushed rock so the slab does not settle into the clay.
3. Form and reinforce. Set forms to the drainage slope and place rebar or wire mesh for vehicle loads.
4. Pour and finish. Place the concrete, screed it flat, and apply the chosen finish.
5. Cut control joints. Joint the slab at proper spacing so it cracks on the lines, not randomly.
6. Cure and protect. Keep the slab moist and protected as it gains strength — slower in our cool, damp climate.

Why Hillsboro Conditions Matter

• Tualatin Valley clay. Washington County's clay holds water and moves seasonally. Without a compacted, well-drained base, a slab settles and cracks. The base is the job.
• Flat ground, slow drainage. Level lots drain slowly, so slope must be built into the driveway and water routed to a real outlet.
• Wet winters. Rain keeps water in the ground; slope and drainage keep it off the slab.
• Easier access. Hillsboro's flatter terrain often simplifies truck and equipment access compared with hillier metros, which can help cost.

The Bottom Line

A concrete driveway in Hillsboro is a long-term investment that pays off when the base and drainage are built for Tualatin Valley clay and slow-draining flat ground. Expect a per-square-foot range driven by thickness, reinforcement, demolition, and access — and make sure the bid covers the base, joints, and slope.
