Which patio finish should you choose?
- Broom finish: the most affordable, with good grip when wet, which matters in Portland.
- Stamped concrete: imitates stone, slate or brick for less than real pavers. See our stamped concrete cost and pattern guide.
- Exposed aggregate: textured, slip-resistant and hides dirt well.
- Colored or stained: adds warmth and can match your home’s trim or stone.
How do you plan a patio for Portland weather?
- Slope it away from the house. About ¼ inch per foot keeps rain from pooling or running toward your foundation.
- Build a real base. 4 inches of compacted gravel prevents settling on clay soils.
- Consider shade and cover. A patio roof or pergola lets you use the space in light rain.
- Plan for moss. Shady patios grow moss in winter; a sealer and textured finish make cleaning easier.
How is a concrete patio built?
- Design and layout: size, shape, finish and drainage are agreed in a free estimate.
- Excavation: sod and soil are removed to the right depth.
- Base and forms: gravel is compacted and forms set for clean edges.
- Reinforcement: rebar or mesh is placed to control cracking.
- Pour and finish: concrete is placed, finished and jointed.
- Cure and seal: walk on it after 1–2 days; furniture after about a week.
Add a fire pit, wall or lighting
Many Portland homeowners add a built-in fire pit or seat wall so the patio works year-round. See fire pit installation cost and rules, and if your yard slopes, read about retaining wall costs and permits. For planting around the patio, see landscape design in Portland. For other flatwork, read our guide to hiring a concrete contractor in Portland or see our patio contractor services in Portland.

Frequently Asked Questions
How much does a 12×12 concrete patio cost in Portland?
A 12 × 12 ft broom-finish patio (144 sq ft) usually costs about $1,200 to $2,600. Stamped or colored concrete raises that to roughly $2,000 to $3,600.
Is a concrete patio cheaper than pavers?
Yes. Plain concrete usually costs about half as much as pavers. Stamped concrete can give a paver-like look for less, though pavers are easier to repair one piece at a time.
How long does a concrete patio last?
With a compacted base, reinforcement, good drainage and occasional sealing, a concrete patio usually lasts 25 years or more.
Do I need a permit for a patio in Portland?
A ground-level patio on your own property usually doesn’t need a building permit, but adding a roof cover, retaining walls over 4 feet or work near property lines may. We check before we quote.
When can I put furniture on a new concrete patio?
Light foot traffic is fine after 24–48 hours. Wait about 7 days for furniture and grills, and avoid dragging heavy items for the first month.
