How do you choose a good concrete contractor in Portland?

1. Verify the CCB license. Every contractor working on Oregon homes must be licensed, bonded and insured with the CCB. Search the name or number on the CCB website and check for complaints.
2. Ask about base prep. A good bid spells out excavation depth, gravel base thickness and compaction.
3. Confirm reinforcement and thickness. Ask whether they use rebar or mesh, and how thick the slab will be.
4. Get a written, itemized bid. It should list demolition, materials, finish, cleanup and permits.
5. Ask about weather. In Portland, a contractor should explain how they handle rain during pours and curing.
6. Read recent reviews and see photos. Look for local jobs similar to yours.

Red flags to watch for

• No CCB number on the bid or website.
• Large cash deposits before any work is scheduled.
• A price far below other bids with no explanation.
• No mention of base, thickness or reinforcement.
• Pressure to sign the same day.

How long do concrete projects take?

Most residential patios and driveways take 2–5 working days to build, then need about 7 days before vehicles can drive on them. Retaining walls take 2–7 days depending on height and drainage. Dry weather from late spring to early fall is the best time to pour in Portland.

Frequently Asked Questions

How much do concrete contractors charge per square foot in Portland?

Most charge about $8 to $18 per sq ft for standard flatwork in 2026. Decorative stamped or colored concrete runs about $14 to $25 per sq ft.

How do I check if a concrete contractor is licensed in Oregon?

Search the contractor’s name or license number on the Oregon Construction Contractors Board (CCB) website. It shows whether the license is active, bonded and insured, and lists any complaints.

What questions should I ask a concrete contractor?

Ask for their CCB number, how deep they excavate, how thick the gravel base and slab will be, what reinforcement they use, how they handle rain, and what the written bid includes.

Why does new concrete crack?

Some hairline cracking is normal, which is why control joints are cut. Larger cracks usually come from a thin or poorly compacted base, missing reinforcement, poor drainage or curing too fast.

Do I need a permit for concrete work in Portland?

Patios on your own lot usually don’t, but driveway approaches, curb cuts, work in the right-of-way and retaining walls over 4 feet generally do. Your contractor should check before quoting.
