Trex Deck Builders in Allen: Certified Installers & Pricing

You want a composite deck that holds up to Allen's brutal summers without warping, fading, or turning into a maintenance headache. Trex is the name that comes up first — and for good reason. But how much does a Trex deck actually cost in Allen? Who installs it properly? And is it worth the premium over other composite brands?

Here's what Allen homeowners need to know before signing a contract.

Why Trex Is Popular in Allen

Allen sits in Collin County where summer temperatures regularly push past 100°F, humidity hovers in the uncomfortable range from June through September, and UV exposure is relentless. That combination destroys traditional wood decks fast.

Pressure-treated pine decks in neighborhoods like Twin Creeks, Montgomery Farm, or Watters Creek often start showing cracks, splinters, and gray discoloration within 2-3 years without aggressive annual maintenance. Cedar holds up slightly better but still demands sealing every 1-2 years.

Trex composite decking handles Allen's climate differently:

• UV resistance — Trex's shell technology resists fading even under North Texas sun. Their higher-end lines include a fade and stain warranty for 25-50 years.
• Moisture resistance — The composite core won't absorb water, which means no swelling, rotting, or mold penetration. Important when Allen gets those sudden spring downpours.
• Termite proof — Subterranean termites are active across Collin County. Composite decking gives them nothing to eat.
• Low maintenance — No staining, sealing, or sanding. Soap and water handles most cleaning.

Allen's building season runs year-round, though most contractors recommend October through April to avoid working (and you standing outside approving details) in peak heat. The upside of year-round availability is more contractor options and better negotiating leverage on pricing.

Trex Product Lines Compared

Trex offers three main product lines, each at a different price point. Here's how they break down for Allen homeowners:

Trex Enhance

The entry-level composite line. Available in two sub-collections:

• Enhance Basics — Solid colors, lighter weight, fewer color options. Good for budget-conscious builds.
• Enhance Naturals — More realistic wood-grain patterns with streaked, multi-tonal coloring.

Both Enhance lines use a protective shell on three sides. They resist staining, scratching, and mold, but the color palette is more limited than premium options.

Best for: Homeowners who want composite benefits without the top-tier price tag.

Trex Select

The mid-range option with a full shell encapsulating all four sides of each board. This means better moisture protection on the underside — relevant in Allen where humidity can trap moisture beneath deck boards.

Select offers richer colors and a more refined wood-grain look than Enhance.

Best for: Homeowners who want durability and aesthetics balanced with a moderate budget.

Trex Transcend

Trex's premium line. Deep, luxury wood-grain patterns that genuinely mimic tropical hardwoods. Available in the Tropics and Earth Tone collections.

Transcend boards feature:

• Full four-sided shell protection
• Superior scratch and stain resistance
• The widest color selection
• 50-year limited warranty (vs. 25-year on Enhance and Select)

Best for: Homeowners building a showpiece outdoor living space and willing to pay for the look and longest warranty.

Quick Comparison

Keep in mind — material cost is only part of the equation. Labor, substructure, and finishing details make up the bulk of your installed price.

Trex Deck Costs in Allen

Let's talk real numbers. In Allen, a Trex deck installed runs $50-80 per square foot in 2026, depending on the product line, deck complexity, and your contractor.

Here's how that breaks down for common deck sizes:

These ranges reflect standard builds. Add-ons push the price higher:

• Built-in lighting — $500-2,000+
• Multi-level design — 20-40% premium over single-level
• Curved or angled sections — More waste, more labor, higher cost
• Railing systems (Trex Signature or Transcend railing) — $50-100+ per linear foot installed
• Permit fees — Allen typically requires deck permits for structures over 200 square feet or 30 inches above grade. Check with Allen's Building/Development Services department for current requirements and fees.

How Trex Compares to Other Materials

When you factor in zero maintenance costs over 25+ years, Trex often costs less than pressure-treated wood over the life of the deck. A pressure-treated deck needing annual staining at $500-800 per session adds up fast. For a deeper look at budget options, check out our guide to affordable deck builders in Dallas.

Finding a TrexPro Certified Installer

Not every contractor who says they install Trex is actually certified by Trex. The distinction matters.

What TrexPro Certification Means

TrexPro installers have completed Trex's training program and demonstrated experience with their products. There are two tiers:

• TrexPro — Trained on proper installation techniques, approved by Trex
• TrexPro Platinum — Higher volume, more experience, access to exclusive Trex products and promotions

A certified installer ensures your warranty stays valid. Improper installation — wrong fastener spacing, inadequate ventilation, incorrect joist spacing — can void Trex's warranty entirely.

How to Find Certified Installers Near Allen

1. Trex's contractor locator — Visit the Trex website and search by zip code (75002, 75013). This pulls up TrexPro and TrexPro Platinum contractors serving Allen and surrounding Collin County.
2. Check credentials — Ask for their TrexPro ID number. Verify it directly with Trex if you're unsure.
3. Request Trex-specific references — Ask to see completed Trex projects, not just general deck work. Installation technique differs from wood framing.

Questions to Ask Before Hiring

• Are you TrexPro or TrexPro Platinum certified?
• Which Trex product lines do you install most often?
• Do you use Trex-recommended hidden fasteners or face screwing?
• What substructure do you use — pressure-treated lumber or steel framing?
• Will you pull the permit, or do I need to handle that with Allen's Building Services?
• What's your timeline? (Allen contractors are typically booked 4-8 weeks out during spring and fall.)

Trex vs Other Composite Brands

Trex dominates the composite market, but they're not the only option. Here's how they stack up against the other major brands Allen homeowners consider:

Trex vs TimberTech/AZEK

TimberTech (owned by AZEK) is Trex's closest competitor.

• TimberTech's Advanced PVC line (fully synthetic, no wood fibers) outperforms Trex in moisture resistance. If your deck is ground-level or near a pool, this matters.
• TimberTech's Pro and Edge lines are comparable to Trex Enhance in price and performance.
• Trex generally has wider retail availability and more certified installers in the DFW area.
• TimberTech offers slightly better scratch resistance in their premium lines.

Verdict: Both are excellent. TimberTech's PVC boards have an edge in extreme moisture situations. Trex wins on availability and installer network size in North Texas.

Trex vs Fiberon

Fiberon offers competitive pricing, often $5-10/sqft less than equivalent Trex lines.

• Fiberon's Concordia and Paramount lines compete with Trex Transcend
• Color options are more limited
• Fewer certified installers in the Allen area
• Warranty terms are similar but Trex has a longer track record of honoring claims

Verdict: Fiberon is a solid budget alternative if you find an experienced installer. For more on brand comparisons, see our roundup of the best composite decking brands — though written for Ontario, the product comparisons apply everywhere.

Trex vs Deckorators

Deckorators is gaining market share with mineral-based composite (MBC) boards that contain zero wood fiber.

• Exceptional moisture and mold resistance
• Lightweight — easier to handle during installation
• Fewer color/texture options than Trex Transcend
• Less brand recognition, which can affect resale value perception

Verdict: Worth considering, especially the Vault line, but Trex's brand recognition and warranty track record still hold weight in Allen's competitive housing market.

Warranty & Maintenance

Trex Warranty Breakdown

Trex offers two types of warranty coverage:

Structural warranty (against material defects):

• Enhance: 25-year limited
• Select: 25-year limited
• Transcend: 50-year limited

Fade & stain warranty:

• Enhance: 25-year limited
• Select: 25-year limited
• Transcend: 50-year limited

Key warranty conditions to know:

• The warranty is transferable to a new homeowner (important for resale in Allen's active housing market)
• Proper installation is required — another reason to use a TrexPro certified installer
• The warranty covers residential use only — commercial applications have separate terms
• Trex defines "fade" as a change beyond a certain Delta E value, not any perceptible change. Some fading within the first few months is normal and expected.

Maintenance in Allen's Climate

Even though Trex is "low maintenance," it's not "no maintenance." Here's what Allen homeowners should actually do:

Monthly (spring through fall):

• Sweep off leaves, pollen, and debris. North Texas live oaks drop leaves constantly from February through April, and accumulated organic material can cause surface mold.

Twice a year:

• Wash with soap and water or a composite deck cleaner. A soft-bristle brush and garden hose works fine. Avoid pressure washers above 1,500 PSI — they can damage the shell.

As needed:

• Clean grease or food stains promptly (soap and warm water)
• Remove any mold or mildew with a composite-specific cleaner. Allen's humidity makes this more common than you'd expect, even on premium boards.

What you'll never do:

• Stain, paint, or seal the deck
• Sand the surface
• Replace rotted or termite-damaged boards

Frequently Asked Questions

How much does a Trex deck cost in Allen, TX?

A Trex deck in Allen costs $50-80 per square foot installed in 2026. A typical 320 sqft deck (16x20) runs $16,000-$25,600 depending on the product line and design complexity. Trex Enhance sits at the lower end, Transcend at the higher end. Add-ons like lighting, railings, and multi-level designs increase the total. Compare this to pressure-treated wood at $25-45/sqft — but remember, Trex eliminates ongoing staining and sealing costs that add up to thousands over the deck's life.

Do I need a permit to build a Trex deck in Allen?

In most cases, yes. Allen typically requires a building permit for decks exceeding 200 square feet or built more than 30 inches above grade. Contact Allen's Building/Development Services department to confirm current requirements for your specific project. Your contractor should handle the permit process, but verify this before signing. Unpermitted decks can cause problems when you sell your home, especially in Allen's competitive resale market.

How long does a Trex deck last in Texas heat?

Trex decks are designed to last 25-50 years depending on the product line. Texas heat and UV are the biggest stress factors, but Trex's shell technology is specifically engineered to resist fading and heat damage. Transcend boards with their 50-year warranty are the best bet if longevity is your priority. Real-world performance in North Texas shows that properly installed Trex decks hold up well, though some color lightening in the first year is normal and stabilizes.

What's the difference between TrexPro and TrexPro Platinum installers?

TrexPro installers have completed Trex's training and meet their basic certification requirements. TrexPro Platinum installers have higher installation volume, more verified experience, and may have access to exclusive Trex promotions or products. Both ensure your warranty remains valid. For Allen homeowners, either certification level is acceptable — the more important factor is checking references, viewing completed local projects, and confirming they pull proper permits.

Is Trex worth it over regular composite decking?

Trex carries a small premium over budget composite brands — roughly $5-15 more per square foot installed — but you get a stronger warranty, better fade resistance, wider color selection, and a larger certified installer network. In Allen's housing market, Trex's brand recognition can also add perceived value to your home. That said, brands like TimberTech and Fiberon offer competitive products.
