2026 PRICING · Updated for 2026 material pricing trends
Real installed pricing for Trex, TimberTech, AZEK, and Fiberon decks across Loudoun, Fairfax, Prince William, and Arlington counties — with side-by-side cost tables, a live calculator, and a 2026 tariff briefing.
Quick Answer
A composite deck in Northern Virginia typically costs $30–$95 per square foot installed in 2026 — a 200 sqft Trex Enhance deck lands around $8,000–$14,000, a 400 sqft Trex Transcend build $24,000–$34,000, and a 500 sqft TimberTech AZEK premium build $40,000–$55,000. Total cost depends on deck size, material tier, stairs, railing system, second-story elevation, and site conditions (slope, soil, access). Loudoun Decks is a Virginia Class A licensed deck contractor in Northern Virginia and a Trex Platinum Partner — every estimate is itemized and free.
Real pricing math — no placeholder numbers. Composite is preselected (Trex Transcend default). The Northern Virginia regional premium of 25–35% is applied to the materials-and-labor base. Every output is a starting point for a free itemized on-site estimate.

Four common deck footprints, three material tiers each. Every total includes pressure-treated framing, the listed composite decking and railings, one stair flight, Loudoun or Fairfax County permit allowance, hidden fasteners, and our 5-year workmanship warranty. Standard rectangular geometry on grade — second-story builds, multi-level decks, and integrated lighting add $3,000–$8,000+ on top.
Prices verified May 2026 against Trex, TimberTech, and Fiberon current MSRP plus Loudoun Decks installed-cost data from 200+ completed NoVA projects.
Most homeowners spend between $22,000 and $38,000on a finished composite deck in Northern Virginia — that's the typical 300–400 sqft mid-tier capped composite (Trex Transcend, TimberTech PRO, or Fiberon Concordia) build with composite railings and one stair flight. Premium PVC and large-footprint luxury builds push past $50,000.
Trex and TimberTech are the two dominant composite brands in Northern Virginia. Pricing is close at the budget tier and separates at the premium tier, where TimberTech AZEK's full PVC core commands a 15–25% premium over the equivalent Trex line. Performance is functionally tied at premium; aesthetics, warranty depth, and color palette drive the real choice.

Composite decking material pricing in 2026 behaves differently from pressure-treated lumber, and the difference matters when you're budgeting a build six months out. Three pressure points dominate the 2026 picture:
Section 232 aluminum tariffs (10–25% depending on country of origin) have lifted aluminum railing system costs roughly 8–15% versus 2024 baseline. Cable rail and modern aluminum picket systems are the most exposed line items on a 2026 composite deck quote. If aluminum railing is on your spec, expect $400–$900 more on a 30-linear-foot run than the same system cost in 2023. Composite railing systems (Trex Signature, TimberTech Impression) are insulated from this tariff because the structural cores are domestic.
Composite boards from Trex, TimberTech, and Fiberon are predominantly US-manufactured (NV and GA for Trex, OH and PA for TimberTech, NC and IA for Fiberon), so they avoid the import tariff exposure that affects competing imported composites. The 2026 squeeze sits on the capstock side: the PVC and acrylic shell layers depend on imported polymer precursors with their own tariff schedules. Net effect on US-made composite board pricing: 3–7% over 2024 levels, smaller than the aluminum impact.
Pressure-treated pine pricing tracks softwood lumber commodity futures — wildly volatile, swinging 20–40% in a single quarter. Composite pricing is set by manufacturer MSRP and dealer programs, which adjust on annual or semi-annual cycles. The practical implication: composite quotes are more stable than wood quotes over the 8–12 weeks between contract signing and material delivery. Most NoVA contractors (including Loudoun Decks) lock material pricing at contract signature for that reason.
2026 composite deck pricing is up roughly 8–14% from 2024 across the NoVA market — driven by labor inflation (NoVA deck-build labor is up faster than national average), the aluminum hardware tariffs above, and incremental capstock cost pressure. If you're budgeting for a 2026 or 2027 build, plan to the upper end of the ranges in our cost tables above.

Every price range on this page is sourced from one of three categories: manufacturer published MSRP, certified dealer pricing programs, or Loudoun Decks internal cost data from completed Northern Virginia builds. We don't use guesses or industry averages; we use the same numbers we quote in our contracts. Prices verified May 2026.
Seven cost levers shape every NoVA composite deck quote. Knowing which ones apply to your build is the difference between a $24,000 and a $40,000 final number for the same square footage.
If you already have a deck and the framing is sound, you can skip 30–50% of the cost by resurfacing instead of full tear-down. Resurfacing strips the old surface boards and railings and installs new composite on the existing structure — only an option when the joists, beams, posts, and ledger pass inspection. Most 20+ year-old NoVA decks need full replacement because the ledger detail predates modern flashing standards. We assess the framing first, then quote.

The post-install cost picture is where composite earns back its upfront premium versus wood. Annual maintenance: $0–$150 (a soap-and-water wash, optional power-wash at low pressure). No staining, no sealing, no sanding. Compare to pressure-treated wood at $1,500–$2,500 every two years for professional clean-sand-stain in NoVA. Over 15 years that's $11,000–$19,000 saved.
A 20×20 (400 sqft) composite deck in Northern Virginia costs $18,000–$42,000 fully installed in 2026, depending on material tier. Budget capped composite (Trex Enhance Basics, Fiberon Good Life) lands at $18,000–$28,000. Mid-tier (Trex Transcend, TimberTech PRO, Fiberon Concordia) lands at $24,000–$34,000. Premium PVC (TimberTech AZEK Vintage, Trex Signature) lands at $32,000–$42,000. Composite railings and one stair flight are included in those ranges; cable railings, lighting, second-story elevation, or a screened porch conversion push totals higher.
For Virginia homeowners holding 7+ years, yes — composite decking pays back through avoided maintenance and longer service life. A pressure-treated wood deck in Loudoun or Fairfax County needs professional power-wash, sand and re-stain every 2 years ($1,500–$2,500 each cycle). Over 15 years that's $11,000–$19,000 in maintenance. Composite needs an annual hose-down. Service life is 25+ years for Trex Transcend, 30–50 years for TimberTech AZEK Vintage, versus 10–15 years for pressure-treated pine. Composite also recovers 65–75% of installed cost at resale (Remodeling Magazine Cost vs Value 2024), versus 40–55% for wood.
Yes. Per Remodeling Magazine's Cost vs Value report, a mid-range composite deck recovers an average of 67.5% of installed cost at resale nationally — and the Mid-Atlantic (which includes Northern Virginia) consistently outperforms that national average by 4–8 percentage points. On NoVA properties valued $750k+, a Trex Transcend deck with named-builder credentials, manufacturer warranty registration, and integrated lighting frequently appraises into the 70–80% recovery band. The harder-to-quantify return is time-on-market: NoVA listings with finished outdoor living spaces sell measurably faster than comparable inventory without them.
Three real alternatives. (1) Pressure-treated pine at $18–$35/sqft installed — cheapest upfront, most expensive over 10 years once maintenance is counted. (2) Cedar at $25–$45/sqft installed — middle ground, lasts 15–20 years in NoVA climate, requires sealing. (3) Fiberon Good Life or ArmorGuard at $28–$45/sqft installed — Fortune Brands–owned composite competitor, capped composite construction, 25-year stain & fade warranty. The honest answer for most NoVA homeowners staying 5+ years: Trex Enhance at $30–$50/sqft beats every cheaper option once you factor maintenance and replacement timing.
Service life varies by capping tier. Capped composite (Trex Transcend, TimberTech PRO, Fiberon Concordia) holds 25+ years with negligible visible aging. Capped PVC (TimberTech AZEK Vintage, Trex Signature) holds 30–50 years with even less aging — full PVC cores don't absorb moisture at all. Uncapped first-generation composites (early 2000s Trex, before the shell technology) failed in 10–15 years; that's the source of the "composite goes bad" reputation, but it doesn't apply to any composite sold since ~2012. Every brand we install today carries a 25-year stain & fade warranty minimum; TimberTech AZEK carries 50 years.
Yes — carefully. Manufacturer guidance from Trex and TimberTech allows pressure washing at low pressure (max 1,500 PSI), a 40° fan tip, held at least 8 inches from the surface, sweeping with the grain. Higher pressure or tight tips will mar the surface cap and void the warranty. For routine cleaning, soap and a garden hose is enough. Heavier seasonal cleaning — pollen, tree sap, leaf staining — pressure-wash at low setting once per spring. Never pressure wash uncapped composite; the exposed core absorbs water and accelerates degradation.
Three reasons. (1) Material cost: composite boards run $4–$12 per linear foot vs $2–$4 for pressure-treated pine. (2) Engineering: composite expands and contracts more with temperature, so fastening, gapping, and joist spacing are tighter — that's installation labor. (3) Hidden fasteners: composite is almost always installed with concealed clip systems (Trex Hideaway, CONCEALoc, Cortex) which cost more and install slower than face-screwed wood. The payoff is back-end: composite eliminates the $1,500–$2,500 every-two-years maintenance cost wood requires, and the boards still look new at year 15 when wood needs replacement.
