Decks here spend most of the year wet and most of the summer in use, and the ones that fail early almost always fail at the ledger, the posts, or the fasteners. Describe your project and we'll connect you with a deck builder Portland metro homeowners have hired for new builds, rebuilds, and rail upgrades.
Most catastrophic deck failures start where the deck attaches to the house. Correct practice means through-bolts or structural screws in a specified pattern, flashing above the ledger so water can't sit against the rim joist, and no attachment to a cantilevered floor or brick veneer. This is inspected in every metro jurisdiction for a reason. If a builder proposes lag screws into unknown framing with no flashing, that alone is disqualifying.
Pressure-treated fir is the budget standard and needs regular cleaning and sealing to avoid checking and moss. Cedar looks and feels better and weathers gracefully if maintained. Composite and PVC boards cost more up front and are popular here precisely because they shrug off moss and don't need annual attention — but the framing beneath them still has to be treated lumber, properly ventilated and flashed.
Guard height, baluster spacing, graspable handrails, consistent stair rise, and proper post-to-frame hardware are where DIY and cut-rate builds fail inspection. Retrofitting rails after the fact is expensive and never looks intentional. Get the rail system decided before framing so the posts land where they should.
We verify Oregon CCB registration, bond, and complaint history, and we point deck work toward builders who do it routinely rather than as an occasional side job. Two to four of them will contact you. There's no cost and no pressure to hire any of them.
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.
Decks across the metro grow moss on shaded sections, hold water in end grain, and rot first at post bases and stair stringers touching soil or concrete. Standoff post bases, gapped boards, and keeping the frame off the ground buy years. If your deck is over fifteen years old and untreated, ask a builder to probe the joist ends and post bases before you spend anything on new surface boards.
Most metro jurisdictions require a building permit for decks above a certain height or attached to the house, but the exact trigger and the setback rules differ between Portland, the Washington County cities, Gresham, and Clackamas County. Hillside lots around Happy Valley and Lake Oswego can also involve geotechnical or steep-slope review. Confirm with your own city or county before assuming a low deck is exempt.
Footing depth and post sizing depend on the ground you're building on, and the metro ranges from flat valley soils to steep, wet hillsides in the west hills and the Clackamas foothills. Builders working sloped sites will spec deeper footings and larger posts, and that cost is legitimate. A quote that ignores your slope entirely is a quote for a different house.
Pressure-treated decks commonly run $30 to $55 per square foot built, cedar somewhat higher, and composite systems often $60 to $100 per square foot once framing, hardware, and rails are included. A 300 square foot composite deck with good rails therefore often lands between $20,000 and $30,000. Height above grade, stairs, hillside footings, and permit fees are the biggest cost movers. Tear-out and disposal of an old deck is usually a separate line — check it's in the bid.
We wanted new boards on the existing frame. The builder pulled one up, showed us rotten joist ends, and we rebuilt properly instead. Uncomfortable news delivered honestly.
Sloped lot, so the footings were deeper and the posts bigger than I expected. He explained why, the inspector signed it off first time, and it feels rock solid.
We only needed the stairs and railing brought up to code before selling. He quoted it as the small job it was rather than trying to turn it into a full rebuild.
Only if the framing, ledger, and posts are sound. New boards on a rotten frame is money spent on a hazard. Have a builder probe the joists, check the ledger flashing, and look at post bases before you commit to a resurface.
For many metro homeowners, yes, because it resists the moss and weathering that make wood decks a yearly chore in this climate. The trade-offs are up-front price, some surface heat in summer, and a look that doesn't suit every house. Wood remains a good choice if you'll actually maintain it.
Spring and summer are the busy season and good builders book months out. Getting drawings and permits sorted in late winter usually secures a better slot and a less rushed crew. Framing can happen in damp weather; staining and sealing cannot.
It depends on your jurisdiction's height threshold and whether it's attached to the house. Several metro cities exempt very low, freestanding platforms; others don't. Ask your builder to confirm with your specific city or county rather than relying on what was true in the last town they worked in.
A maintained pressure-treated deck often gives 15 to 20 years, cedar similar with more care, and composite surfaces considerably longer. The framing usually determines the real lifespan, which is why hardware quality and flashing matter more than the boards you see.
