TimberTech Deck Installation
Handis TimberTech deck installation builds a new composite deck using the TimberTech residential line — Reserve (full PVC, 50-year warranty), Legacy or Vintage (premium capped composite, 30-year warranty, the deepest wood-grain emboss in the category), or Edge (mid-tier capped, 25-year warranty) — with the TimberTech Concealoc hidden-fastener system, color-matched TimberTech fascia at the rim, and TimberTech composite or aluminum railing — built on pressure-treated framing at the TimberTech-specified joist spacing, ledger through-bolted and Z-flashed per IRC, and TimberTech warranty registered on your behalf after final inspection — from $32,000 for a standard Vintage or Edge build on a 300 to 400-square-foot footprint to $68,000 for a premium Reserve PVC build with cap rail, mitered fascia, picture-frame border, and aluminum baluster railing on a larger footprint. TimberTech (owned by AZEK Building Products) makes the deepest wood-grain emboss in the composite category — Legacy and Vintage read closest to real wood at arm's length, often closer than the homeowner expects. Reserve is full cellular PVC with the longest residential warranty (50-year limited fade-and-stain). We install all four TimberTech residential tiers and will recommend the right one on the booking call.

How a TimberTech Deck Install Works
Seven sequential phases from site staking through TimberTech warranty registration — the actual sequence Handis runs on every new TimberTech composite build.
Site Staking + Footing Layout + Permit
Estimate visit confirms the footprint, the TimberTech line (Reserve, Legacy, Vintage, Edge), the color, the railing, and any add-ons. Site staked, footing locations marked, the Seattle DCI permit pulled under Handis's general-contractor license. Stamped engineering coordinated if required.
Concrete Piers (or Helical Piers) + Post Bases
Pier footings poured to engineer's spec or to prescriptive depth — typically 18 to 36 inches deep depending on lot, frost depth, and load. Galvanized or stainless post bases set into the wet concrete or anchored to cured piers. Helical piers on the engineered hillside builds with torque logging per pier.
Pressure-Treated Framing + Ledger
PT beams set on post bases, joists hung at the TimberTech-specified spacing (12-inch on-center on Reserve and Legacy, 16-inch on-center on Vintage and Edge). On attached builds, the wall behind the ledger is opened, bottom plate inspected and replaced if rotted, then the ledger through-bolted with 1/2-inch hot-dipped galvanized or stainless lag bolts at IRC R507.9.1.3 spacing and Z-flashed under the siding.
Framing Inspection
Seattle DCI (or jurisdiction equivalent) framing inspection. Inspector verifies pier spacing, joist hangers, ledger bolt pattern and flashing, post bases. Decking install holds until the framing inspection passes.
TimberTech Decking Install with Concealoc Hidden Fasteners
TimberTech boards laid out with the picture-frame border at the perimeter, field boards butt-cut clean to the inside of the frame, Concealoc clips set in the groove of each board edge, screw driven into the joist below at every clip. Gap spacing per TimberTech spec. Mitered corners on the fascia and the picture-frame border.
Color-Matched TimberTech Fascia + Railing + Cap Rail
Color-matched TimberTech fascia installed at the rim joist. TimberTech composite railing (or aluminum baluster upgrade) at 36-inch (or 42-inch on raised decks per WA Residential Code), 4-inch sphere baluster spacing rule met. Cap rail set flat across the top.
Final Inspection + TimberTech Warranty Registration
Final inspection scheduled with the permit office. Inspector verifies railing height and baluster spacing, stairs and stair railings, and overall completion. Permit closed, permit copy provided. Handis registers the TimberTech warranty on your behalf within the manufacturer's window with original paperwork; you receive the registration confirmation and the warranty certificate.
TimberTech Deck Pricing
Final pricing depends on TimberTech line (Reserve PVC vs Legacy vs Vintage vs Edge), deck square footage, color and grain selection, railing system (TimberTech composite vs aluminum baluster upgrade), and whether stamped engineering is required. Engineering, Seattle DCI permit fees, and any licensed-electrical portions are pass-through line items named in the project total. Request a free in-home estimate for an accurate quote.

Why Homeowners Book Handis for TimberTech Decks
TimberTech is the brand the wood-purist homeowner picks. The deep wood-grain emboss on Legacy and Vintage is the closest any composite gets to reading as real wood at arm's length — the kind of detail that takes the guest's first comment from "is that composite?" to "I assumed cedar". Reserve takes the brand into full PVC territory with a 50-year warranty — the longest residential warranty in the broader composite/PVC category. AZEK (TimberTech's parent company) built the brand on the premium end of the market and the products earn the position. The tradeoff is price — TimberTech runs $2,000 to $5,000 more than Trex per build at comparable size, and Reserve runs $5,000 to $10,000 more than Transcend. For homeowners where the look and the warranty both matter, TimberTech is the right answer. We install all four residential lines and we will tell you on the booking call which one fits.
Estimate
Tell us the square footage you have in mind, the TimberTech line (Reserve PVC, Legacy, Vintage, Edge — or you want a recommendation), the color preference (the TimberTech catalog has 6 to 10 colors per line), the railing system (TimberTech composite standard, aluminum baluster upgrade), and any add-ons (stairs, built-in bench, low-voltage lighting, hot-tub framing). We send a clear estimate with the TimberTech spec, the warranty terms, and the permit/engineering pass-through line items named.
Customer Reviews
Recent TimberTech deck reviews from real Handis customers.
380-square-foot TimberTech Legacy in Pecan on an attached deck in Bellevue. Concealoc hidden fasteners, 12-inch joists per Handis spec, mitered fascia at every corner. The wood-grain emboss is genuinely deep — when guests visit they assume it is real wood until I tell them. Came in right at $42,000 including the aluminum baluster railing upgrade. Through 14 months and no fade in the high-traffic walkways.
TimberTech Reserve PVC (Driftwood color) on a 700-square-foot premium build in Mercer Island. Full PVC, 50-year warranty. Handis built at 12-inch on-center joists, mitered the fascia at every corner, installed glass-panel railing on the view side and Reserve composite cap on the house side. Coming up on year two and the deck looks identical to the day it finished. The PVC is genuinely no-maintenance.
TimberTech Vintage (Mahogany color) on a 340-square-foot floating deck in our Queen Anne back yard. Sub-30-inch elevation so no permit needed. Handis built it in 12 working days. Concealoc fasteners, color-matched fascia, picture-frame border. The Mahogany reads warm and traditional — fits the Craftsman bungalow perfectly. $39,500 total.
480-square-foot TimberTech Legacy (Tigerwood color) on a multi-level Sammamish hillside build. Stamped engineering, helical piers, two elevations. Handis brought the structural engineer in early, framed in three weeks, decked and railed in another. Total install $58,000 including engineering and permit. Tigerwood reads like an actual exotic hardwood at any visitor's distance.
TimberTech Edge (Sandalwood color) on a 290-square-foot attached deck in Renton. Entry-tier line, 25-year warranty, mid-range budget. Handis explained the difference between Edge and Vintage on the estimate visit — said the Edge boards have a less-deep emboss but the same Concealoc system and the same color durability, just a shorter warranty term. Right call for our budget. $33,000 total. Solid honest brand-tier guidance.
