How to use
AZEK Vintage (flagship PVC, 50-yr warranty), AZEK Harvest (mid PVC), AZEK Landmark (hardwood-look PVC), PRO Reserve (premium capped composite), PRO Legacy (mid capped composite), EDGE Prime+ (value composite, Lowe's-stocked alternative to Trex Enhance).
Up to 6 colors per line. PVC colors run noticeably cooler than capped composite at the same tone — even AZEK Vintage Mahogany stays comfortable in full sun. Heat-rating icons (Flame/Snowflake) show the surface-temp expectation.
Length × width in feet. Pattern matters: parallel (7% waste, 1.0× labor), picture-frame (12%, 1.18×), diagonal (15%, 1.12×). The calculator quantizes board count using TimberTech's stocked lengths (12, 16, 20 ft).
CONCEALoc (TimberTech's hidden clip system) is the default — 90 clips/box, $85/box, 50 sqft coverage. Cortex (color-matched plug system, 50/pack, $38/pack) is the face-screw alternative.
AZEK Drink Rail (top-mount decking face on railing — premium upgrade, $45/lf installed). TimberTech Lighting (post + riser LEDs + 100W transformer + low-voltage wiring).

Three honest paths. Composite wins the 25-year math for most homeowners, wood wins on upfront cost, and PVC is unbeatable around water. Each card below answers in one glance — recalculate the bill of materials by clicking a brand in the picker above.
How we calculate
The TimberTech Deck Calculator is the brand-deep estimator for the homeowner who has decided on TimberTech (an AZEK Building Products brand) and wants a real bill of materials with TimberTech part numbers, the right CONCEALoc clip box count, optional AZEK Drink Rail under-mount, optional TimberTech Lighting, and a side-by-side comparison across all 6 TimberTech lines — AZEK Vintage / Harvest / Landmark (PVC) plus PRO Reserve / Legacy (capped composite) plus EDGE Prime+ (value composite). The big differentiator vs Trex: TimberTech AZEK PVC carries a 50-year structural warranty (the longest in residential decking) and runs noticeably cooler in dark colors. Pricing reflects 2026-Q1 retail from Lowe's Pro + TimberTech AZEK Pro dealer channel.
Per-LF retail prices reflect 2026-Q1 TimberTech pricing at Lowe's Pro + TimberTech AZEK Pro dealer channel. CONCEALoc + Cortex specs from TimberTech install manuals. AZEK Vintage 50-yr warranty per AZEK Building Products published terms.
Rows = ceil(width × 12 ÷ (5.5 + 0.125)) — TimberTech face is 5.5″ with 1/8″ install gap. Waste % is pattern-driven.
Each CONCEALoc box has 90 clips, covers ~50 sqft at 16″ joist o.c. Total clips = boards × (length × 12 ÷ 16 + 1). Loose remainder priced at $1.15/clip.
Each Cortex pack has 50 color-matched plugs, covers ~50 sqft. Used when fastener=cortex-plug.
Premier/Reserve/Builder rail posts go every 6 ft. One post light per post, plus end caps. One riser light per stair tread.
TimberTech installs are 25% slower than face-screwed PT. Pattern + shape multipliers compound. Region uses RSMeans 2026-Q1.

Both make excellent decking — TimberTech AZEK has the longer warranty (50 yr structural vs Trex 25 yr) and runs cooler in dark colors (PVC reflects more heat than capped composite). Trex has the broader color palette (27 colors across all lines vs TimberTech's ~16). Pick TimberTech for warranty + heat performance; pick Trex for color choice + broader Home Depot availability.
AZEK is 100% PVC — 50-year structural warranty, runs cooler, doesn't absorb water. PRO is capped composite (wood fiber + plastic core) — 30-year structural warranty, more wood-grain authenticity in the cap. AZEK is the premium tier; PRO is the mid-tier; EDGE Prime+ is the value entry.
$50-110 per square foot installed depending on line + pattern. A 16×20 (320 sqft) deck in TimberTech EDGE Prime+ with railing and 4 stairs lands around $18,500 nationally; the same deck in TimberTech AZEK Vintage with a Premier Rail aluminum system and DrinkRail lands around $34,000+. Multiply by 0.92× South or 1.28× West Coast.
TimberTech's hidden-fastener clip system for grooved boards. Each box has 90 clips and covers ~50 sqft at 16″ joist on-center spacing. Box price is $85; loose clips $1.15 each. The clip nests into the board's edge groove and screws into the joist, leaving a clean screw-free surface. Equivalent to Trex's TUHF system but slightly cheaper per box.
Three channels: Lowe's (stocks EDGE + parts of AZEK + PRO palettes), Lowe's Pro Desk (full PRO + AZEK with special-order), and TimberTech AZEK Pro dealers (find at timbertech.com/find-a-pro — full palette including Landmark, plus Premier Rail aluminum). AZEK Pro dealers maintain the longest lead times (2-4 weeks) but full palette access.
Less than capped composite at the same color — PVC reflects more solar heat. Even AZEK Vintage Mahogany stays under 145°F at the surface in 90°F full sun (vs 160-170°F on a comparably-dark capped composite). For maximum heat performance, pick AZEK over PRO regardless of price tier.
A top-mounted decking face on the rail post system — turns the railing top into a bar/drink shelf. Installed $45/lf on top of the rail kit cost. Popular for outdoor kitchens and entertaining decks. Adds ~$1,600 to a 36 lf railing run.
After you set dimensions + pattern + fastener + stair count, the calc prices the same deck across all 6 TimberTech lines (Vintage, Harvest, Landmark, Reserve, Legacy, Prime+) using each line's per-LF retail. Tap any to switch the calculator to that line; the color picker resets to the new line's first color. Fastest way to see what jumping from EDGE Prime+ to AZEK Vintage costs on your specific deck.
Yes — TimberTech AZEK PVC carries a 50-year structural warranty, the longest in residential decking. Fade & stain warranty is 30 years. PRO composite is 30/30. EDGE Prime+ is 25/25. All warranties are transferable; register at timbertech.com/why-timbertech/warranty within 30 days of install for full coverage.
Yes — TimberTech publishes detailed install manuals at timbertech.com/install. CONCEALoc clip systems are sequential (you can't easily skip ahead and double-back) so plan ~1.5 hr/sqft for first-time DIY. AZEK Pro dealers offer install training programs for serious builders. Materials savings vs an AZEK Pro contractor are typically 50-60% of total project cost.
