Deck Cost in Clark County, WA (2026)
What decks really cost here — composite/Trex, cedar, and pressure-treated wood — plus the factors that move the number. No "it depends" runaround.
Most deck companies make you book an appointment just to hear a price. We don't. Below are the typical installed cost ranges we see across Clark County — Vancouver, Camas, Ridgefield, Battle Ground and beyond — so you can plan your project with real numbers.
Typical installed cost per square foot
| Decking material | Installed cost / sq ft | Best for |
|---|---|---|
| Pressure-treated wood | $18–$35 | Lowest up-front cost; needs regular sealing |
| Cedar | $25–$45 | Natural look; still needs maintenance |
| Composite (entry, e.g. Trex Enhance) | $28–$45 | Low maintenance, great value |
| Premium composite (e.g. Trex Transcend) | $45–$65 | Best looks, longest warranty, near-zero upkeep |
Ranges are typical installed costs in Clark County, WA and are for planning only — your exact price depends on the factors below. We confirm a real range before we start.
What moves the price
- Size & shape — larger and more complex layouts cost more per project; simple rectangles are most efficient.
- Height — ground-level decks are cheapest; elevated and multi-level builds need more framing, posts, and railing.
- Railing — composite is standard; aluminum, cable, and glass railing cost more (but protect views).
- Stairs & landings — each run adds framing and labor.
- Tear-out — removing and hauling an old deck adds to a replacement.
- Site & slope — hillside lots in Camas, Washougal, and Felida need engineered footings.
Composite vs. wood over time
In our wet climate, composite and Trex resist rot, mold, and warping with almost no maintenance and a 25-year+ warranty. Cedar and pressure-treated wood cost less up front but need regular sealing and eventually replacement. We'll walk you through the trade-offs honestly. Over a 25-year horizon, the sealing, staining, and board replacement on a wood deck often erases its lower up-front price — which is why most Clark County homeowners upgrade to composite when they replace.
Do you need a permit?
Yes, in most cases. Clark County exempts only decks that meet all of these: 200 sq ft or less, no more than 30 inches above grade at any point, not attached to the house, and not serving a required exit door. Exceed any one of those — bigger, higher, attached, or at an exit — and a permit is required. We handle the permitting for you. Rules differ slightly between incorporated cities (Vancouver, Camas, Washougal, Ridgefield, Battle Ground, La Center) and unincorporated Clark County areas (Hazel Dell, Salmon Creek, Brush Prairie, Felida) — we handle whichever applies to you.

FAQ
Deck cost questions
How much does a composite or Trex deck cost in Clark County?
For most homes here, composite/Trex decks run about $28–$65 per square foot installed, depending on the line (Enhance vs. Transcend), height, railings, stairs and tear-out. We give you a real range before you commit.
How much does a pressure-treated wood deck cost?
Pressure-treated wood decks typically run $18–$35 per square foot installed — the lowest up-front cost, but plan for sealing every year or two and eventual board replacement.
How much does a cedar deck cost?
Cedar decks generally run $25–$45 per square foot installed. Cedar looks beautiful and is naturally rot-resistant, but still needs regular sealing to hold its color in our climate.
What's the total price for an average deck?
A typical 300–400 sq ft composite deck in Clark County often lands somewhere between $12,000 and $26,000 installed depending on height, railing and complexity. We refine that to an exact number on your free quote.
Why do you publish prices when most builders won't?
Because hiding price wastes everyone's time. Real ranges let you plan and trust us before we ever meet, and they filter out surprises. We give an exact quote after seeing the project.
What factors change the price of a deck the most?
Size, height above grade, railing type (composite vs. cable/glass), number of stairs, tear-out of an old deck, and site conditions like slope. Height and railing are the two that move the number most.
Does a taller or elevated deck cost more?
Yes. Elevated and multi-level decks need more framing, taller posts, deeper footings and more railing, so they cost more per square foot than a simple ground-level deck.
How much does deck railing add?
Basic composite railing is included in most quotes; upgrading to aluminum, cable or glass railing adds cost but preserves views. Railing can be a meaningful share of the total on a small deck.
Does removing my old deck cost extra?
Yes — tear-out and haul-away of an existing deck is added to a replacement job. It's usually a modest line item, and we roll it into your written quote.
Do permits add to the cost?
Permit fees in Clark County are relatively modest and we include them in your quote. The bigger value is that we handle the paperwork and inspections so it's done right.
Is composite worth the higher up-front cost?
Over 25 years, the sealing, staining and board replacement a wood deck needs often erases its lower up-front price. Most homeowners who plan to stay in their home find composite is the better lifetime value.
Do you offer financing?
Financing options vary — ask us on your quote and we'll point you to current options. Many homeowners use home-equity or contractor financing for larger builds.
How much does a covered deck or patio cover cost?
Covered structures cost more than an open deck because of the roof framing, posts and roofing material. We price the deck and the cover separately so you can see each part.
Will a new deck increase my home's value?
A well-built deck is consistently one of the better-returning outdoor projects, and low-maintenance composite is especially attractive to buyers in the PNW. It also expands your usable living space now.
Do you charge for an estimate?
No. Quotes are free. Tell us your town and project type through the form and we'll give you a same-day range, then an exact written quote after we see the site.
Why are quotes from different builders so far apart?
Usually it's what's under the surface — footing depth, joist spacing, ledger flashing, and hidden fasteners. A cheap bid often skips the parts that keep a deck safe for decades. Compare scope, not just price.
How much does deck repair cost?
Repairs vary widely — a few loose boards or a railing fix is a small job, while replacing rotted joists or footings costs more. We quote repairs honestly and tell you if replacement is the smarter spend.
Do prices change by town in Clark County?
Not much by town — labor and materials are similar county-wide. What changes cost is the specific site: slope, access, height and how much old structure has to come out.
What's the cheapest way to get a durable deck?
A simple, ground-level rectangular deck in pressure-treated wood is the lowest cost, and you can upgrade the surface to composite later. We'll help you phase it if budget is tight.
How accurate is the range you give over the form?
Our same-day range is a solid planning number based on your description. The exact price is locked in after we see the site, confirm materials, and put it in writing — with no surprise add-ons.
