Outdoor living here is a nine-week season and a nine-month endurance test. A deck that isn't detailed for constant wet will be soft at the ledger before it's ten. Whether you want a new deck, a rebuild, or a fence line that stops leaning, describe the yard and we'll find a deck builder in Portland who works lots like yours.
Sometimes the framing is fine and only the decking and railing need replacing — that's the cheap, satisfying version. Sometimes the posts have wicked moisture out of the soil for twenty years and the whole thing has to go. A builder should probe the posts, the ledger, and the joist tops before quoting. Ask them what they found, not just what they'd charge.
Pressure-treated framing is standard and fine. For the walking surface, cedar looks right on older Portland homes but demands regular attention or it greys and cups. Composite and PVC cost more up front, shrug off moss, and are what most people here choose when they're tired of maintenance. Whatever goes on top, joist tape over the framing is a small cost that adds years.
Cedar remains the local default and it does well if the posts are set properly and the bottom rail isn't sitting in soil. Sloped lots need stepped or racked panels, and both look better when that's a design decision instead of an improvisation. Before anything goes in the ground, agree the line with your neighbour — shared-fence disagreements are far more common than shared-fence contracts.
Describe the project once and we match it with vetted local pros who actually do this work — you choose who to hire, or nobody at all.
Portland generally requires a permit for decks above a certain height off grade or attached to the house, and for anything with structural implications. Fences have height limits that differ between front and rear yards. Portland Permitting & Development is where both get resolved, and a builder who knows the thresholds saves you the discovery-by-inspector version of this lesson.
A ledger board bolted to the house without proper flashing lets water into the rim joist, and in this climate that rot is quiet and expensive. Correct detailing — flashing over the ledger, spacers for drainage, structural fasteners rather than nails — is what separates a twenty-five-year deck from a fifteen-year one. Ask any bidder to describe their ledger detail.
Decks under mature firs stay damp and grow a slick moss film that becomes a genuine hazard by February. Plan for airflow beneath the deck, keep leaf litter off it, and expect to clean it each autumn. Fence post holes near big trees also hit roots, and cutting through significant roots of a protected tree is not something to do casually in this city.
A pressure-treated deck commonly runs $35–$60 per square foot installed, cedar somewhat more, and composite frequently $60–$110 per square foot once railing is included. Railings, stairs, and elevated framing on a sloped lot drive the price more than deck area does. Cedar fencing typically lands around $35–$60 per linear foot installed, higher for hillside stepping or removal of an old fence. Bids that look low are usually spacing posts wider or skipping concrete footings — ask about post depth and footing detail.
Our deck felt spongy near the house. He pulled a board, showed me the rotten rim joist, and rebuilt the ledger with proper flashing this time.
Steep back yard and a leaning fence. The stepped cedar panels look intentional now and the posts are set far deeper than the old ones were.
We were set on cedar until he walked us through what the shaded north side of the yard does to it every winter. The composite bid came in close and we've stopped thinking about the deck.
Fifteen to twenty years for well-built framing, but the walking surface often needs attention sooner in shaded, wet locations. Annual cleaning and a finish that's actually reapplied on schedule is the difference between a deck that ages and one that rots.
Ground-level detached decks below the city's height threshold often don't, but attaching to the house or building higher changes that. Confirm with Portland Permitting & Development or let your builder handle it — the cost of a permit is trivial next to rebuilding an unpermitted deck before a sale.
Crews book out for spring and summer, so requesting quotes in late winter gets you a better slot. Framing and fencing can happen in wet months, though concrete work and finishes prefer a dry stretch and schedules slip accordingly.
That's between you and your neighbour, and Oregon has rules about shared boundary fences worth reading before the conversation. Practically, most Portland neighbours split the cost when both benefit. Get the agreement in writing before the old fence comes down.
