Composite Deck Resurface (over existing frame)
The cedar deck off the back of the 1996 Bellevue house, structural frame still sound after a decade of careful maintenance but the surface boards are checked, split, and tired of being stained every three years. The 1989 pressure-treated deck off the Wedgwood craftsman, owner does not want to spend another fifteen years on stain-and-replace cycles and is ready for a no-stain composite. The 2003 Sammamish deck where the wood surface boards are failing but the structural joists, beams, and posts inspect sound. Composite deck resurface over an existing frame is the trade for replacing the entire deck surface with premium composite (Trex Transcend, TimberTech AZEK, Fiberon Sanctuary, or Azek Vintage) over a structural frame that has been inspected and confirmed sound — full board removal, exhaustive joist and hanger inspection with sister-up where needed, new composite installed with Cortex or Camo hidden fasteners, new composite fascia around the perimeter, new composite post caps on every visible post. From $28,000 for a small-to-medium deck (200-400 sq ft) with mid-tier composite to $65,000 for a large deck (600-800 sq ft) with premium composite, full hidden-fastener system, new fascia, and new post caps. Honest scope — the project assumes the structural frame inspection comes back sound or repairable within the joist scope. When the frame fails or the ledger and rim need to come apart, the project crosses into permit-required structural rebuild and routes to a licensed Washington L&I general contractor.

What Does Composite Deck Resurface (over existing frame) Include?
Composite deck resurface over an existing frame is a multi-day project that replaces every visible board on the deck while preserving the existing structural framing — joists, beams, posts, footings, and ledger. We remove the entire wood board surface, perform an exhaustive frame inspection (every joist awl-probed and moisture-metered, every hanger visually checked, ledger and rim inspected), sister-up any compromised joists with matched pressure-treated stock, replace any failed joist hangers with Simpson ZMAX or stainless equivalents, install the new composite boards with the brand-matched Cortex or Camo hidden-fastener system, install new composite fascia around the perimeter, install new composite post caps on every visible post, and deliver a written punch report with dated photos. Scope assumes the structural frame is sound or repairable within the joist scope. When the frame fails — multiple joists rotted past sister-up, ledger crossing into rim-joist replacement, beams or posts compromised, footings failing — the project routes to a licensed Washington L&I general contractor with engineer-stamped drawings and a building permit.
Full Board Removal and Frame Exposure
The existing wood boards come off entirely. Hidden-fastener systems get the appropriate extraction tool from truck stock; nailed and screwed surfaces get the fasteners backed out (or cut where corroded beyond extraction). Old boards stage for haul-off or recycle depending on condition and local diversion availability. Once the boards are off, the structural frame is fully exposed — every joist visible from above, every hanger visible at the rim and the beam, every post top accessible.
Exhaustive Frame Inspection from Above and Below
Every joist gets an awl probe along its full length and a moisture meter reading at the ledger end, mid-span, and rim end. Every joist hanger gets a visual check for rust-through, back-out, and joist-to-hanger separation. The ledger gets a fastener-type and flashing inspection with rim-joist moisture reading through the lag holes. Beams get a visual check for splitting and rotation; posts get a visual check at the base and the top. We document what we find with a written punch list and dated photos before any new board goes down.
Joist Sister-Up and Hanger Replacement Where Needed
Compromised joists get sistered up with matched dimension pressure-treated stock (typical 2x8 or 2x10), structural screws driven in a staggered pattern, full bearing on both ends. Failed Simpson hangers get replaced with ZMAX (G185 hot-dipped galvanized) or stainless equivalents, sized to the joist depth, fastened with Simpson SDS structural screws. The frame work is itemized separately on the quote (we cannot estimate exactly how many joists will need sister-up until the boards come off). When the frame work exceeds the joist and substructure repair scope, the project routes to a licensed Washington L&I GC.
New Composite Boards with Cortex or Camo Hidden Fasteners
The owner-selected composite brand and line (Trex Transcend, Trex Enhance, TimberTech AZEK, TimberTech PRO, Fiberon Concordia, Fiberon Sanctuary, or Azek Vintage) gets installed across the entire deck surface using the brand-matched hidden-fastener system. Cortex collated plugs (top-down install with a recessed plug glued or pressed into a sleeve), Camo blind-screw collated (edge-driven from the side), or FastenMaster slotted clips (between-board edge clip) — sized to the deck-board brand and the joist spacing. Boards run in the orientation the owner has selected (parallel to the house, perpendicular, picture-frame perimeter with field boards inside).
New Composite Fascia and Post Caps
Fresh composite fascia board (matched to the deck-board brand and color line) gets installed around the entire perimeter, mitred at the corners or scarf-joined for long runs, fastened with stainless or color-matched composite fasteners. Composite post caps (matched brand) install on every visible post top. Post wraps (full-height composite sleeves over existing structural posts) install as an optional add-on.
Finish Punch and Dated Photo Report
Final walkthrough with the homeowner: every board confirmed flush, every hidden fastener confirmed seated, every fascia mitre confirmed tight, every post cap confirmed level. Dated photo report covers before-and-after of the structural frame inspection, the joist sister-up work, the hidden-fastener install, the fascia install, and the post caps. One-year project warranty on the carpentry; the composite manufacturer warranty (typically 25-to-50 years on boards) is in the manufacturer's name and registered to the homeowner.
How Composite Deck Resurface Works
Six sequential steps from full board removal through frame inspection, sister-up, composite install, fascia and post caps, and the finish punch — the sequence we follow on every composite deck resurface project.
Full Board Removal and Frame Exposure
All existing wood deck boards come off. Hidden-fastener systems get the appropriate extraction tool; nailed and screwed surfaces get the fasteners backed out or cut. Old boards staged for haul-off or recycle depending on condition. The structural frame becomes fully exposed for inspection.
Exhaustive Frame Inspection from Above and Below
Every joist awl-probed along its full length and moisture-metered at the ledger end, mid-span, and rim end. Every joist hanger visually checked for rust-through. Ledger fastener-type and flashing inspection with rim-joist moisture reading. Beam and post visual check. Written punch list and dated photos before any new board goes down.
Joist Sister-Up and Hanger Replacement Where Needed
Compromised joists sistered with matched pressure-treated stock and structural screws on full bearing. Failed Simpson hangers replaced with ZMAX or stainless. Frame work itemized separately on the quote. Frame failures beyond the joist scope route to a licensed Washington L&I GC.
New Composite Boards with Cortex or Camo Hidden Fasteners
Owner-selected composite brand and line (Trex Transcend, TimberTech AZEK, Fiberon Sanctuary, Azek Vintage, etc.) installed using the brand-matched hidden-fastener system. Cortex collated plugs top-down, Camo blind-screw edge-driven, FastenMaster slotted clips between boards. Board orientation per owner selection.
New Composite Fascia and Post Caps
Fresh composite fascia board (matched brand and color line) around the entire perimeter, mitred at corners or scarf-joined for long runs, fastened with stainless or color-matched composite fasteners. Composite post caps install on every visible post. Full-height post wraps optional add-on.
Finish Punch Walkthrough and Dated Photo Report
Final walkthrough with the homeowner. Every board confirmed flush, every hidden fastener confirmed seated, every fascia mitre confirmed tight, every post cap confirmed level. Dated photo report covers the inspection, the sister-up, the hidden-fastener install, the fascia, and the post caps. One-year project warranty on the carpentry; composite manufacturer warranty registered to the homeowner.
Composite Deck Resurface Pricing
Final pricing depends on deck square footage, the composite brand and line (mid-tier versus premium), the hidden-fastener system, whether new fascia and post caps are in scope, and the extent of joist sister-up and hanger replacement work uncovered when the existing boards come off. Frame failures beyond the joist scope route to a licensed Washington L&I GC and are quoted as a pass-through. Request a free estimate for an accurate quote.

Why Handis for Composite Deck Resurface
A composite resurface over a still-sound frame is the most cost-effective way to get fifteen to twenty more years out of a deck that already has the right footprint, the right height off grade, and the right structural sizing. The decision matrix runs like this — if the frame is sound, resurface over the existing structure and save the cost of a full re-frame. If the frame is failing, the project is a full rebuild and routes to a permit-GC. The inspection that decides which side of that line you are on comes off the moment the existing boards lift; the frame inspection budget is included in the quote so the worst-case scenario is visible before we start. We will not tell you the frame is sound when it is not, and we will not tell you the frame is failing to push you into a bigger scope. The reading is what it is and the report goes to you in writing.
Exhaustive frame inspection the moment the boards come off
Composite resurface only makes sense over a sound structural frame. The moment the existing wood boards lift, every joist gets an awl probe along its full length plus a moisture meter reading at the ledger end, mid-span, and rim end. Every joist hanger gets a visual check for rust-through and back-out. The ledger gets a fastener-type and flashing inspection with rim-joist moisture reading. Beam and post visual check. Written punch list and dated photos before any new composite goes down. The frame inspection is included in the project price — we do not invoice a separate diagnostic fee for it.
Joist sister-up and hanger replacement budget already in the quote
Most frame inspections we do find at least one or two joists that benefit from sister-up and at least a handful of joist hangers that benefit from ZMAX replacement. The project quote includes a budget for up to 2 joists sister-up (mid-tier package), 3 joists (medium), or 4-to-5 joists (large package). Joists beyond the included budget are itemized at $1,200 each; hangers at $150 each. The worst-case frame-work number is on the quote before we start, so the project scope does not balloon mid-build.
Brand-matched Cortex or Camo hidden fasteners on every board
Hidden-fastener systems are what makes a composite resurface look like a furniture install instead of a deck. Cortex collated plugs (top-down install with a recessed plug glued or pressed into a sleeve, matched to the deck-board color), Camo blind-screw collated (edge-driven from the side, completely invisible from above), or FastenMaster slotted clips (between-board edge clip, no visible fastener at all). The brand and the model match the deck-board brand — Cortex makes plugs for every major composite brand, Camo works with most groove-edge boards. Visible fasteners are not how you finish a $40,000 composite deck.
Honest GC handoff when the frame inspection comes back failing
A failed frame is not a Handis composite resurface. When the inspection comes back showing multiple joists rotted past sister-up, the ledger crossing into rim-joist replacement, beams or posts compromised, or footings failing, the project crosses into permit-required structural rebuild and routes to a licensed Washington L&I general contractor with engineer-stamped drawings. We name the GC and the engineer on the quote, pause the composite scope until the structural portion closes, and resume the composite install over the new frame after the GC signs off. The composite material and the homeowner deposit are protected by the contract during the pause.
Composite manufacturer warranty registered to the homeowner
Each major composite brand (Trex, TimberTech, Fiberon, Azek) carries a manufacturer warranty of 25 to 50 years on the boards covering structural integrity, fade, and stain. The warranty is in the manufacturer's name and registered to the homeowner at install — we provide the product serial numbers, the registration paperwork, and the install date documentation. Our project warranty covers the carpentry (board flush, hidden-fastener seat, fascia mitre, post-cap level) for one year; the manufacturer warranty covers the board itself for the warranty period.
Insured, background-checked, one-year project warranty on carpentry
Handis carries general liability and workers' compensation; every technician has cleared a background screening before the first job. The carpentry — board flush, hidden-fastener seat, fascia mitre, post-cap level, sister-up integrity, hanger fastening — carries a one-year project warranty. The composite material warranty is the manufacturer's responsibility and runs longer (25 to 50 years on most major brands). The licensed-GC and engineer portions on any structural escalation carry their own Washington L&I-trade warranty.
Estimate
Tell us the deck size in square feet, the height off grade (single-tier or multi-tier), the existing board material (cedar, pressure-treated, hardwood), the composite brand and line you have in mind (Trex Transcend, TimberTech AZEK, Fiberon Sanctuary, Azek Vintage — or ask us to recommend), and any add-ons you want (picture-frame perimeter, post wraps, fascia color, post-cap style). Send phone photos of the deck from multiple angles plus a few flashlight shots from underneath if you can. We will quote the resurface with frame inspection budget visible, so you see the worst-case scenario before any board comes off.
Customer Reviews
Recent composite deck resurface reviews from verified Seattle-area customers.
1998 cedar deck off our Mercer Island house, 420 sq ft, the cedar surface was tired but the frame was solid. Handis quoted a TimberTech AZEK resurface with picture-frame perimeter, Cortex hidden fasteners, new fascia, and post caps. Frame inspection came back clean — they sistered one joist as a precaution and replaced eight hangers with ZMAX. Five working days. The deck looks like a furniture store and the project ran exactly to the worst-case quote.
Big two-tier deck off our Sammamish house, 720 sq ft total. We wanted Trex Transcend on the main level and the upper landing. Handis ran the full project — full board removal, frame inspection (which found three joists needing sister-up and 14 hangers needing replacement), new boards with Cortex throughout, new fascia, new post caps, post wraps on the eight visible posts. Eleven working days. Coordinated cleanly with our schedule. Premium build, premium result.
1989 pressure-treated deck off our Wedgwood craftsman, 280 sq ft. We were considering a full rebuild but Handis was honest that the frame was still sound and a composite resurface would be the right scope. Mid-tier Trex Enhance, Cortex hidden fasteners, new fascia, new post caps. Six working days. The honest scope call saved us probably $20,000 versus a full rebuild we did not need.
2005 PT deck off our Bellevue house, 480 sq ft. The frame inspection came back with bad news — two joists past sister-up, the ledger crossing into rim-joist work, the project had to escalate to a permit-GC. Handis was honest the moment the inspection came back, named a licensed Washington L&I GC, the GC came in with engineer drawings, did the structural portion, then Handis returned to do the composite. Four months total. The honest handoff was the difference between a successful project and a disaster.
Smaller Fiberon Concordia resurface on our Capitol Hill house, 250 sq ft. Picture-frame perimeter with field boards perpendicular. Cortex hidden fasteners, color-matched plugs. Frame was clean — one hanger replaced. Four working days. Premium finish on a smaller deck where the cost ratio still made sense. Five-year warranty registration paperwork was handed over with the project closeout.
