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.

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.
