Our Deck & Patio Approach

Built for Portland weather. Built to last.

Portland gets 40+ inches of rain a year. Every deck and patio we build accounts for water management, material expansion, and subgrade drainage before the first board or paver goes down.

Structural details, fastener spacing, and drainage slope are set during planning so the finished surface holds up through freeze-thaw cycles and wet-season saturation without callbacks.

Common Questions

Deck & Patio Construction FAQ

01Do decks require permits in Portland?

Decks over 30 inches above grade or attached to the house require permits in Portland. We file applications and coordinate inspections as part of the project.

02What deck materials work best in Portland?

Pressure-treated lumber is the most cost-effective. Cedar resists rot naturally. Composite lasts longest with minimal maintenance but costs more upfront.

03How long does deck construction take?

A standard deck runs 1 to 3 weeks from footing to finish. Covered structures, built-in seating, or multi-level designs can extend to 3 to 5 weeks.

04How much does a deck cost in Portland?

Pressure-treated decks start around $30 to $45 per square foot. Cedar runs $40 to $60. Composite ranges from $50 to $80 per square foot installed.

05Can you replace an old deck without removing the footings?

Sometimes. Existing footings can be reused if they meet current code and are structurally sound. We inspect them before confirming the approach.
