Meet Your Local
Portland Deck Builder

We have finished 1,250+ deck projects since 2008, from small Hawthorne townhouse decks to steep hillside builds in Alameda and Mt. Tabor. Every carpenter is on our own payroll, so no subcontractor shows up at your house. We build across Portland in 6 materials: Western Red Cedar, IPE hardwood, Trex Transcend, TimberTech AZEK, Deckorators composite, and PVC. Cedar costs less at the start, and you re-stain it every 2 to 3 years. Composite costs more and holds up 25 to 30 years with no staining.

We hold Oregon CCB License OR CCB #248317, a $25,000 bond, and $2M liability coverage. We have been a NADRA (North American Deck and Railing Association) member since 2008. We also hold BBB A+ accreditation, TrexPro Platinum, and TimberTech Pro certification. We pull every PP&D and Multnomah County permit in house, so you never file paperwork yourself.

Every build carries a 10-year structural warranty that transfers to the next owner if you sell. Call (503) 782-9723 and a builder answers, not a receptionist.

Materials ยท Honest Trade-Offs

Decking Materials We Build With

We install all 5 and push no house brand. The right board depends on 3 things: how much sun your site gets, how fast it dries after rain, and what you want to spend on upkeep.

Cedar Decking

Western Red Cedar is the traditional Pacific Northwest deck board. It still looks best on an older Portland home, and it costs the least up front. You re-stain it every 2 to 3 years, or it turns grey and cracks.

Lifespan15โ€“20 yrs 300 sq ft$12kโ€“$18k Details โ†’

Composite Decking: Trex, TimberTech & Deckorators

Capped composite is what we install most in Portland, for one reason: rain does not hurt it. You never sand or re-stain it, and the fade warranty runs 25 to 30 years. We install Trex Transcend, Trex Lineage, and Deckorators Voyage, and we are TrexPro Platinum and TimberTech Pro certified.

Lifespan25โ€“30 yrs 300 sq ft$18kโ€“$32k Details โ†’

PVC & AZEK Decking

PVC boards hold zero organic content, so mould and rot have nothing to feed on. Pick PVC for shaded north-facing yards and for rooftop terraces that sit over a waterproof membrane.

Lifespan30+ yrs 300 sq ft$22kโ€“$36k Details โ†’

IPE & Tropical Hardwood Decking

IPE is dense enough to sink in water and carries a Class A fire rating, which matters on the Forest Park side of town. It costs the most and needs every fastener pre-drilled. It also outlasts every other board here.

Lifespan50โ€“75 yrs 300 sq ft$32kโ€“$78k Details โ†’

Pressure-Treated Decking

Pressure treated fir is the budget board, and it frames almost every deck in the city. It works as a surface too. Expect it to move, splinter, and need sealing from the first year.

Lifespan10โ€“15 yrs 300 sq ft$8kโ€“$14k Details โ†’

Which Decking Material Lasts Longest in Portland's Rain?

Portland gets about 36 inches (91 cm) of rain a year, and many yards never see winter sun. Constant damp plus shade is what kills decks here, not cold. Ranked on exactly that:

Material Lifespan Wet-climate Upkeep Cost
IPE hardwood 50โ€“75 yrs Excellent Oil yearly (optional) $$$$
PVC / AZEK 30+ yrs Excellent Rinse only $$$
Capped composite 25โ€“30 yrs Very good Rinse only $$$
Western Red Cedar 15โ€“20 yrs Good if sealed Re-stain 2โ€“3 yrs $$
Pressure-treated 10โ€“15 yrs Fair Seal yearly $

IPE lasts the longest in Portland rain. PVC needs the least upkeep, capped composite gives most Portland homes the best value, and cedar still wins on looks and price when you actually re-stain it on schedule. Full breakdown โ†’

2025 Portland Pricing

How Much Does a Deck Cost in Portland?

Most Portland deck projects cost between $7,500 and $35,000. These are real numbers from jobs we quoted this year, not national averages. Here is how that splits by job type, and what moves your number up or down.

Deck Repair Cost

$400 to $9,500

  • Board and railing fixes: $1,800 to $4,200
  • Joist sistering and structural work: $4,800 to $7,500
  • Full ledger reset: $6,000 and up

Most repairs come in under $4,500. We quote a repair before a replacement any time the framing allows it. Deck repair details โ†’

Deck Resurfacing Cost

$8,000 to $16,000

  • New decking on sound framing
  • New railing to current code
  • Typically 3โ€“6 build days

Resurfacing costs 45% to 55% of a full rebuild. It only works when the joists, beams, and footings pass inspection. Resurfacing details โ†’

New Deck Cost by Size & Material

Deck size Pressure-treated Cedar Composite IPE
200 sq ft (10ร—20) $8,000โ€“$11,000 $11,000โ€“$15,000 $15,000โ€“$21,000 $24,000โ€“$32,000

Multi-level 600+ sq ft $22,000โ€“$30,000 $29,000โ€“$38,000 $38,000โ€“$52,000 $58,000โ€“$78,000

Prices include materials, labor, footings, railing, permits, and disposal. They exclude electrical work, hot tub structural upgrades, and retaining walls.

What Changes Your Price

Height above grade Any deck over 30 inches (76 cm) needs a permit, engineered footings, and code railing. A deck 8 feet (2.4 m) up costs about 40% more than the same deck at ground level.
Slope and soil West Hills and Mt. Tabor lots often need stepped footings or helical piers. Flat lots in Roseway and Parkrose need drainage work instead.
Material grade Material moves your price more than anything else. The same 300 sq ft (28 sq m) frame carries pressure treated boards at $12,000 or IPE at $40,000.
Demolition & disposal Tearing out an old deck runs $1,200 to $3,500. Size, side-yard access, and whether the old footings come out set the number.
Railing and stairs Cable railing, aluminum, and glass panel cost 3 to 5 times what wood costs. A long stair run down to grade adds $2,000 to $6,000.
Permit & engineering PP&D permit fees run $185 to $685. Stamped structural drawings add $600 to $1,800 when the city asks for them.

Financing Options

We work with Synchrony Financial and Wells Fargo Outdoor Solutions on projects from $2,500 to $75,000. Terms run 6 months, 12 months, or 60 months, and many homeowners qualify for a 0% APR (Annual Percentage Rate) promotional period. Approval takes a few minutes, and it never changes your quoted price.

Portland Permitting & Development (PP&D)

Deck Permits & Building Code in Portland

Portland enforces deck permits, and a deck built without one shows up later at 3 points: resale, appraisal, and insurance claims. We file every document in house and build the review time into your schedule, so the wait never surprises you.

When a Portland Deck Needs a Permit

Permit required
  • The deck surface sits more than 30 inches (76 cm) above grade at any point
  • It attaches to the house (a ledger connection is structural)
  • The deck covers more than 200 sq ft (18.6 sq m), even when freestanding and low
  • It carries a hot tub, outdoor kitchen or other concentrated load
  • You are adding or altering stairs, guardrails or roof structure
  • The work replaces more than 50% of the structural members
Usually exempt
  • Freestanding decks 30 inches (76 cm) or lower that stay under 200 sq ft (18.6 sq m)
  • Like-for-like board replacement on sound existing framing
  • Sanding, staining, sealing or refinishing
  • Railing repair that does not change the structure

Permit fees in Portland run $185 to $685 for a normal home deck, and plan review takes 2 to 4 weeks. Homes in the Wildland-Urban Interface (WUI) near Forest Park also need fire-resistant boards and gaps no wider than 1/8 inch (3 mm).

We Handle Permits, Drawings & Inspection

Permit handling is built into every quote, and we never add it as a line item later. The work takes 4 steps, and we do all of them:

  1. 01
    Measure & draw We measure the site, then draw the framing plan, footing schedule, and elevations to the Oregon Residential Specialty Code (ORSC).
  2. 02
    Structural engineering We bring in a licensed Oregon Professional Engineer (PE) for stamped calculations, whenever the deck is elevated, cantilevered, or on a slope.
  3. 03
    Submit to PP&D We file the set with Portland Permitting & Development and answer every plan-review comment the reviewer sends back.
  4. 04
    Inspections Your deck gets 3 inspections: footings before the pour, framing before the boards go down, and a final at completion. We meet the inspector on site each time.
Licensed and verifiable

Our licence is Oregon CCB #248317. Check it yourself on the Oregon Construction Contractors Board lookup. We also carry a $25,000 bond and $2M liability coverage.

Repair or Replace? An Honest Assessment

A rebuild pays us about 10 times what a repair pays, so treat any 5-minute rebuild pitch with doubt. About 4 in 10 of the decks we inspect need a repair only. We put that in writing every time, even though the repair is the smaller job for us.

Repair it The structure is still doing its job
  • Ledger is dry, flashed and solidly bolted to the rim joist
  • Footings are below frost line and have not shifted or heaved
  • Joists ring solid when struck, with no soft spots at the hangers
  • Damage is confined to surface boards and railing
  • The deck is under 20 years old
  • Framing is pressure treated rather than bare fir

Typical result: $1,800 to $8,500 and 1 to 5 days on site. Repair service โ†’

Replace it The framing has failed or was never right
  • The ledger is nailed only, unflashed, or rotted where it meets the wall
  • Posts are set directly in soil or concrete without standoff bases
  • Multiple joists are soft, split or sistered badly by a previous owner
  • The deck moves sideways when you push against it
  • Repair costs would pass 60% of a new deck
  • It was built without a permit and cannot pass inspection as-is

Typical result: $14,500 to $45,000 and 6 to 21 days on site. Replacement service โ†’

A third option sits between the two, and most homeowners never hear about it. We resurface, when the frame passes but the boards are finished. You get new decking and railing on your existing structure for about half the cost of a rebuild. Resurfacing is the right answer more often than either extreme, so we check for it first.

8 Portland Deck Builder FAQs

Deck Builder Portland
Questions Answered

These are the 8 questions Portland homeowners ask us most before hiring a deck builder. They cover cost, permits, materials, timelines, and WUI fire-zone rules. Every answer is direct.

How much does a Portland deck builder cost?

A Portland deck costs between $7,500 and $35,000 for most projects. A 300 sq ft (28 sq m) Western Red Cedar deck runs $12,000 to $18,000 installed. The same footprint in Trex Transcend or TimberTech AZEK composite costs $18,000 to $28,000. IPE hardwood runs $28,000 to $65,000. Five things set your price: square footage, material grade, height above grade, hardware such as Simpson Strong-Tie connectors and hidden fasteners, and PP&D permit fees. Call (503) 782-9723 for a real number in 5 minutes.

Specific answer for your deck? Call (503) 782-9723
Do I need a permit to build a deck in Oregon?

Yes, a deck over 30 inches (76 cm) above grade needs a Portland Permitting & Development (PP&D) permit. Your submission needs structural drawings, ledger attachment details, and footing specs. Washington County permits apply in Beaverton and Tigard, and Clackamas County permits apply in Lake Oswego and West Linn. Plan review adds 2 to 4 weeks. We file every document in house, so the paperwork never reaches you.

Specific answer for your deck? Call (503) 782-9723
What is the best deck builder in Portland?

Check 4 credentials before you hire any Portland deck builder: NADRA (North American Deck and Railing Association) membership, BBB A+ accreditation, TrexPro or TimberTech Pro certification, and an active Oregon CCB licence. A good crew hands you all 4 without hesitation. We hold every one. Our 17 years of Pacific Northwest (PNW) work, 1,250+ finished projects, and 4.9/5 rating across 312+ Google reviews are all things you can check yourself.

Specific answer for your deck? Call (503) 782-9723
What deck material works best for Pacific Northwest climate?

Capped composite works best for most Pacific Northwest homes, because rain and shade do not hurt it. Western Red Cedar costs less at $12,000 to $18,000 for a 300 sq ft (28 sq m) deck. You re-stain it every 2 to 3 years, or the wood opens up and rots. Trex Transcend and TimberTech AZEK need no staining and carry 25 to 30 year warranties, though they warm up on south-facing decks in July. IPE hardwood lasts 50 years or more and resists rot and insects on its own, at $28,000 to $65,000. Pick PVC decking such as AZEK or Fiberon for rooftop and riverfront builds. Portland gets 36 inches (91 cm) of rain a year, so board spacing and drainage matter as much as the board you pick.

Specific answer for your deck? Call (503) 782-9723
What questions should I ask a Portland deck builder?

Ask a Portland deck builder these 6 questions before you sign: What is your Oregon CCB licence number? What are your bond and insurance amounts? Do you hold NADRA, TrexPro, or TimberTech Pro certification? Does the quote include PP&D permits, structural engineering, and joist tape? What does the warranty cover, and for how long? Will any subcontractor work on my site? Every answer should be specific, written, and something you can verify. A contractor who gets defensive has already answered you.

Specific answer for your deck? Call (503) 782-9723
Can you build a deck off an existing deck in Portland?

Yes, you can build off an existing Portland deck, when the original ledger and footings meet current code. We check 3 things first: ledger attachment strength, footing depth and condition, and joist span ratings. The extension ties in with Simpson Strong-Tie connectors and matching joist tape, if the existing structure passes. Any addition over 30 inches (76 cm) above grade needs a permit.

Specific answer for your deck? Call (503) 782-9723
How long does Portland deck construction take?

A Portland deck takes 1 to 21 construction days, depending on the work. Board and railing repairs finish in 1 to 3 days. Resurfacing existing framing takes 3 to 5 days. A new 300 sq ft (28 sq m) build takes 6 to 10 days. Multi-level hillside decks and rooftop decks in Hawthorne or Southwest Hills take 12 to 21 days. PP&D permit review adds 2 to 4 weeks before any building starts, so count that into your date.

Specific answer for your deck? Call (503) 782-9723
What are WUI deck requirements in Portland?

Wildland-Urban Interface (WUI) rules apply to Portland homes in mapped fire-risk zones near Forest Park and the wooded west edge. These decks need 3 things. First, fire-resistant boards such as composite, ignition-resistant cedar, or Class A rated hardwood. Second, board gaps no wider than 1/8 inch (3 mm) to stop embers. Third, metal flashing where the deck meets the wall. Trex, TimberTech AZEK, and IPE all meet the standard. We prepare the compliance paperwork for PP&D review.
