Decks project by Weatherguard Construction in Northglenn, Colorado

When Northglenn homeowners search for a deck contractor they can trust, Weatherguard Construction rises to the top — and not just because of our five-star reviews and manufacturer certifications. We've earned our reputation by building decks that are structurally superior from the ground up, starting with Owens Corning structural lumber for every ledger board, post, and stair stringer we install.

Why does structural lumber matter? Because Colorado's high altitude means UV radiation is up to 25% stronger than at sea level, causing rapid fading and material degradation in substandard decking products. Standard pressure-treated lumber absorbs moisture, swells, shrinks, and eventually rots — especially at the ledger connection and ground-contact points. OC Lumber is rotproof, rustproof, and rated for underwater contact — engineered to protect against what wood and steel simply cannot.

We pair that engineered foundation with premium composite and PVC decking from Wolf, TimberTech AZEK, and Trex — 89 authentic colors across 20 collections that resist fading, staining, scratching, and mold without annual sealing or staining. For homeowners who want the ultimate structural package, we offer a full OC Lumber frame upgrade — every joist, beam, rim board, and blocking piece in Owens Corning structural lumber.

Composite Decking: The Smart Choice for Northglenn Homeowners

Composite decking blends recycled wood fibers with high-density polyethylene plastic, creating a board that mimics the warmth of natural hardwood while resisting the rot, insects, and weather damage that destroy traditional lumber. For Northglenn homes facing sub-zero temperatures, heavy snowfall, and persistent ice accumulation, composite decking delivers decades of reliable performance without the annual chore of sanding, staining, or sealing.

Trex — America's Most Trusted Composite Brand

As a certified Trex installer, Weatherguard offers the full Trex lineup to Northglenn homeowners:

  • Trex Signature: The pinnacle of Trex luxury — photorealistic woodgrain with engineered hardwood aesthetics. The most durable Trex decking available in 2 exclusive colors: Whidbey and Ocracoke. 50-year limited residential warranty.
  • Trex Transcend Lineage: Elevated aesthetics with SunComfortable™ heat-mitigating technology that keeps your deck noticeably cooler. 7 luxurious colors including Biscayne, Jasper, Rainier, Carmel, Island Mist, Hatteras, and Salt Flat. 50-year limited residential warranty.
  • Trex Transcend: Deep wood-grain texture and multi-tonal colors inspired by exotic hardwoods. 6 colors: Havana Gold, Island Mist, Tiki Torch, Spiced Rum, Lava Rock, and Rope Swing. Curveable and scratch-resistant. 50-year warranty.
  • Trex Select: Curated colors with refined grain patterns and SunComfortable™ technology in the new collection. 5 colors: Whiskey Barrel, Malted Barley, Millstone, Pebble Grey, and Saddle. 35-year warranty.
  • Trex Enhance: Authentic wood-grain at an accessible price. 10 colors across Naturals (Foggy Wharf, Rocky Harbor, Toasted Sand, Honey Grove, Cinnamon Cove, Golden Hour) and Basics (Saddle, Clam Shell, Tide Pool, Pebble Beach) sub-lines. SunComfortable™ technology in select colors. 25-year warranty.
  • Trex Refuge: Fire-resistant PVC decking with Class A Flame Spread Rating and IWUIC compliance. West Coast-inspired colors: Martis Valley and Point Reyes. 50-year limited residential warranty.

Every Trex board is manufactured from 95% recycled materials — including reclaimed wood and polyethylene film — making it one of the most environmentally responsible decking choices available. Trex boards will never need sanding, staining, or painting, and they resist fading, staining, scratching, and mold better than any wood species on the market.

Fiberon — Performance Meets Sustainability

Fiberon composite decking combines sustainability with striking aesthetics. Their capped composite technology wraps each board in a protective polymer shell that locks out moisture and resists fading, staining, and scratches. Popular collections include:

  • Fiberon Concordia: Premium multiblend coloring with dramatic grain patterns and a matte finish.
  • Fiberon Good Life: A value-oriented line with solid performance ratings and a clean contemporary look.

Fiberon boards are manufactured in the USA using up to 94% recycled content and carry a 25-year structural warranty along with comprehensive fade and stain coverage.

Deck Maintenance in Colorado: What You Actually Need To Do

One of the biggest advantages of composite and PVC decking is the near-total elimination of maintenance headaches. Unlike wood decks that demand annual staining, sealing, sanding, and board replacement, your Weatherguard composite or PVC deck requires only minimal care:

  • Periodic Sweeping: Remove leaves, pine needles, and debris to prevent staining from organic material sitting on the surface for extended periods.
  • Occasional Washing: A garden hose or pressure washer on a gentle setting is all you need to keep your deck looking fresh. For stubborn spots, a mild soap solution and a soft-bristle brush will handle virtually any stain.
  • Snow Removal: Use a plastic shovel or broom to clear heavy snow. Avoid metal shovels that could scratch the surface. Calcium chloride ice melt is safe for composite and PVC — but avoid rock salt, which can leave residue.
  • Furniture Pads: Place protective pads under heavy furniture legs to prevent point-load compression marks. This is especially important for metal chairs on hot days when the deck surface is more pliable.

That is it. No sanding. No staining. No sealing. No replacing warped or rotted boards. Just enjoy your deck, season after season, while your neighbors spend their weekends maintaining theirs.

Understanding Deck Warranties: What Northglenn Homeowners Should Know

Not all deck warranties are created equal, and understanding the differences can save you thousands of dollars and decades of frustration. Here is a breakdown of the warranty coverage available through Weatherguard's manufacturer partnerships:

Structural Warranties

These cover the core integrity of the decking board — resistance to splitting, cracking, rotting, and structural failure under normal use. Premium products like TimberTech AZEK and Trex Transcend carry Limited Lifetime structural warranties, meaning the boards are warranted against structural defects for as long as you own your home.

Fade and Stain Warranties

This is where cheap decking gets exposed. Budget products may carry a 10-year fade warranty, but premium lines from TimberTech AZEK provide a 50-year fade and stain warranty — guaranteeing your deck's color and finish will remain vibrant for half a century. Trex Transcend products also carry a 50-year warranty against fading and food stains.

Labor and Workmanship Warranties

Materials are only part of the equation. A poorly installed deck will fail regardless of board quality. Weatherguard's craftsmanship warranty covers our installation work — including joist connections, fastener patterns, railing attachments, and structural connections — giving you complete peace of mind.

Our Northglenn design consultants walk you through every warranty detail during your estimate appointment so you understand exactly what protection your investment carries before you commit.

Deck Styles and Configurations for Every Northglenn Property

No two Northglenn backyards are identical, and neither should their decks be. Weatherguard designs and builds custom deck configurations tailored to your property's topography, your home's architecture, and the way your family actually uses outdoor space. Here are the most popular deck styles we build across Colorado:

  • Platform Decks: Ground-level designs that flow seamlessly from your back door into your yard. Ideal for flat lots and single-story homes, platform decks create an accessible entertaining space without the need for railings or stairs in most cases.
  • Raised Decks: Elevated structures that provide panoramic views of your yard while creating valuable covered storage or patio space underneath. Essential for homes with walkout basements or sloped terrain — extremely common in Northglenn neighborhoods.
  • Multi-Level Decks: Tiered designs that define distinct activity zones — a cooking and grilling station, a dining area, a lounge space, and a ground-level fire pit pad. Multi-level decks add dramatic architectural interest to your home while maximizing usable square footage.
  • Wraparound Decks: Decks that extend along two or more sides of your home, providing multiple access points and diverse sun and shade exposures throughout the day. A wraparound design also maximizes your outdoor living area without expanding your home's footprint.
  • Pool Decks: Slip-resistant, moisture-proof surfaces designed specifically to surround in-ground and above-ground pools. Our PVC and composite materials stay cooler underfoot than concrete or stone and will never splinter — critical safety features for barefoot use around water.
  • Covered Decks and Porches: Extend your deck season by adding a full or partial roof structure. Covered decks protect your furniture, your grill, and your family from rain and excessive sun while creating a more intimate, room-like outdoor experience.
  • Cantilevered Decks: Architecturally striking designs that project outward beyond their support structure, creating a floating visual effect. Popular on modern homes where clean lines and dramatic geometry are part of the design language.
  • Screened Deck Enclosures: Full or partial screen systems that keep mosquitoes and insects out while preserving airflow and natural light. A screened deck turns your outdoor space into a comfortable three-season room without the cost of a full enclosure.

Why Northglenn Homeowners Choose Weatherguard for Deck Construction

Building a deck is a significant investment — one that should enhance your daily life for decades. Here is why Northglenn families consistently choose Weatherguard Construction over the competition:

  • Manufacturer Certifications: We hold installer certifications from Trex, TimberTech AZEK, Wolf, Fiberon, and Deckorators.

Our certifications unlock enhanced warranty coverage that standard installers cannot offer.
  • Structural Engineering Expertise: Every Weatherguard deck is designed to meet or exceed Colorado's residential building codes. We calculate proper beam spans, joist spacing, footing depths, and snow load requirements for your specific property — not generic cookbook formulas.
  • Transparent, Fixed-Price Quotes: Our written estimates include every cost — materials, labor, permits, footings, demolition of your old deck, and final cleanup. The price you approve is the price you pay. Period.
  • Clean, Professional Jobsites: Our crews clean up daily, protect your landscaping, and treat your property with the same respect they would show their own homes. We know how disruptive construction can be, and we work hard to minimize the impact on your daily routine.
  • Full Permit Management: We handle all permitting, inspections, and code compliance requirements in Northglenn and throughout Colorado. You never have to visit a building department or coordinate with an inspector — we manage all of it.
  • Comprehensive Warranty Coverage: Beyond manufacturer warranties on materials, Weatherguard provides our own craftsmanship warranty covering structural integrity, fastener performance, and installation quality.

Composite vs. PVC Decking: Choosing the Right Material for Your Northglenn Deck

Both composite and PVC deliver far superior performance to wood, but they have distinct characteristics that make each better suited to different situations. Here is an honest comparison to help you decide:

FeatureComposite DeckingPVC Decking
CompositionWood fibers + recycled plastic100% engineered polymer
Moisture ResistanceExcellent (capped shell protection)Superior (zero moisture absorption)
WeightHeavier (similar to wood)Lighter (easier to handle)
Heat RetentionModerate (can get warm in direct sun)Lower (stays cooler underfoot)
Scratch ResistanceVery goodExcellent
Price Range$$ to $$$$$$ to $$$$
Best Warranty25-year to Limited LifetimeLimited Lifetime + 50-year fade/stain
Ideal ForBudget-conscious upgrades, ground-level decksHigh-traffic areas, pool decks, maximum longevity

Our recommendation? If your budget allows, PVC decking provides the ultimate in low-maintenance performance and longevity. If you want an exceptional deck at a lower investment, composite delivers outstanding value and will dramatically outperform any wood deck. Either way, you are making a smart upgrade over traditional lumber.

Deck Enhancements That Elevate Your Northglenn Outdoor Living

A great deck is more than boards and railings — it is a complete outdoor living environment. Weatherguard offers a full suite of enhancements that transform a simple deck into the centerpiece of your Northglenn home:

Premium Railing Systems

Your railing choice dramatically impacts both safety and style. We install railing systems from the industry's top manufacturers, including:

  • Composite and PVC Rails: Color-matched TimberTech, Trex, and Fiberon rails that blend seamlessly with your deck boards for a unified, polished look.
  • Aluminum Rails: Sleek, powder-coated aluminum systems from Westbury and Deckorators that provide unobstructed views and modern curb appeal. Available in black, bronze, and white finishes.
  • Cable Rails: Stainless steel cable infill systems from Viewrail that create an open, contemporary aesthetic. Ideal for properties with scenic views you want to preserve.
  • Glass Panel Rails: Tempered glass infill panels that provide wind protection and uninterrupted sightlines. The premium choice for elevated decks and waterfront properties.

Integrated Deck Lighting

Professional LED lighting extends your deck's usable hours well into the evening while creating inviting ambiance. We install recessed post cap lights, stair riser lights, under-rail accent strips, and perimeter landscape lighting — all on low-voltage LED systems that cost pennies per day to operate and last for years without bulb changes.

Privacy Walls and Wind Screens

Custom-designed horizontal slat privacy walls, louvered screens, and lattice panels provide seclusion from neighbors without sacrificing airflow or natural light. Available in matching composite, cedar, and aluminum materials.

Deck Skirting and Fascia

Finished skirting conceals the underside of raised decks, blocking debris buildup and pest access while creating a clean, polished appearance from every angle. We use color-matched composite fascia boards and ventilated lattice to ensure proper airflow beneath your deck structure.

Underdeck Drainage Systems

For raised decks, a ceiling-mounted drainage system captures rainwater running between deck boards and channels it away from the space below, creating a dry, usable patio area underneath your elevated deck — effectively doubling your outdoor living square footage.

Pergolas and Shade Structures

Freestanding or attached pergolas add architectural drama and provide adjustable shade coverage over your deck. We build with composite, cedar, and aluminum materials, including motorized louvered pergola systems that open and close at the touch of a button.

FAQ

Common Questions About Decks in Northglenn

Can Weatherguard remove my old wood deck before building a new one?

Absolutely. Full demo and removal of your existing deck is included as a standard part of our service. Our crew carefully dismantles old framing, decking, and railings, sorts materials for responsible disposal or recycling, and leaves your site clean and ready for new construction. If your existing substructure (joists and beams) is in solid condition, we can sometimes reuse it — saving you money on framing costs.

Can I add lighting, privacy walls, or a pergola to my deck later?

Yes, but we strongly recommend incorporating these features during initial construction whenever possible. Adding lighting, privacy walls, pergolas, or underdeck systems during the build is significantly more cost-effective than retrofitting later, because the framing can be designed to support these additions from the start. If you are considering these features even as a future possibility, mention it during your design consultation so we can plan the structural support now.

How does Weatherguard handle deck demolition and rebuilding in Northglenn?

Our full-service approach includes careful demolition of your existing deck, responsible disposal and recycling of old materials, inspection of the house rim joist and attachment points, installation of new frost-depth footings, framing with Owens Corning structural lumber for ledger boards, posts, and stair stringers, and final installation of your chosen composite or PVC decking and railing system. We handle permitting, inspections, and cleanup — you just enjoy the finished product.

Will a composite or PVC deck increase my Northglenn home's value?

According to industry data, a well-built composite deck recoups approximately 65-75% of its cost in added home value at resale — and often more in competitive Colorado markets where buyers prioritize low-maintenance outdoor living. Beyond the financial return, a beautiful deck significantly improves buyer appeal and can help your home sell faster. Unlike a wood deck that depreciates as it weathers, composite and PVC decks maintain their appearance and value for decades.

What railing options are available for my Northglenn deck?

Weatherguard installs a wide range of railing systems: composite rails from Trex and TimberTech that match your deck boards, powder-coated aluminum rails from Westbury and Deckorators in black, bronze, and white, stainless steel cable rails from Viewrail for a modern open look, and tempered glass panel systems for unobstructed views. Each system meets Colorado residential building code requirements for height, spacing, and load capacity.

Do I need a permit to build a deck in Northglenn, Colorado?

In most cases, yes. Northglenn and the surrounding Colorado municipalities require building permits for deck construction, particularly for raised decks, structures attached to your home, and any deck over a certain height or square footage. Weatherguard handles the entire permitting process — we prepare the application, submit drawings, coordinate inspections, and ensure your deck is 100% code-compliant. You never need to visit a building department.

What are the signs my Northglenn deck needs to be replaced?

Key warning signs include: soft or spongy boards when you walk across them, wobbly or loose railings, visible rot at the ledger board (where the deck meets your house), cracked or split stair stringers, posts that feel soft at ground level, popped or loose fasteners, and significant structural bounce when multiple people walk on the deck. If your Northglenn deck is 15+ years old and built with standard pressure-treated lumber, a professional structural inspection is strongly recommended — the damage that matters most is often hidden inside the framing.

How much does a composite deck cost in Northglenn, Colorado?

Composite deck costs in Northglenn typically range from $45 to $85 per square foot installed, depending on the material tier, deck configuration, railing selections, and site conditions. A standard 300 square foot deck generally falls between $13,500 and $25,500, while larger multi-level designs with premium features can range from $35,000 to $65,000 or more. Weatherguard provides free, itemized estimates so you see exactly where every dollar goes — no hidden fees or surprise charges.

Does Weatherguard build commercial decks in Northglenn?

Yes. Weatherguard Construction provides commercial deck and outdoor living construction for multi-unit residential properties, HOA communities, restaurants and hospitality venues, retail spaces, and corporate campuses throughout Northglenn and Colorado. Our commercial projects use the same premium materials and craftsmanship standards as our residential work, with added engineering for higher traffic loads and ADA compliance requirements.

What footings does Weatherguard use for deck construction in Northglenn?

We use three primary footing systems depending on your site conditions and local code requirements: poured concrete footings (the traditional standard, excavated below Colorado's frost line), helical piers (steel screw-in piles that require no excavation and are ideal for tight-access sites), and diamond pier foundation systems (engineered precast blocks with steel pins). All footing systems are designed to prevent frost heave and provide a stable, level foundation for decades.

What deck brands does Weatherguard install in Northglenn?

Weatherguard is a certified installer for Trex (including Signature, Transcend Lineage, Transcend, Select, Enhance, and Refuge lines), TimberTech AZEK (Vintage, Landmark, Harvest+, and Harvest Advanced PVC collections), TimberTech Composite (Legacy, Reserve, Terrain+, Terrain, Prime+, Premier+, and Premier collections), Wolf (Serenity PVC, Haven composite, and Perspective composite), Fiberon (Concordia and Good Life composite), and Deckorators. Our manufacturer certifications ensure your deck qualifies for the strongest available warranty coverage.

Does Weatherguard build decks during Colorado winters?

Yes. Weatherguard builds decks year-round in Colorado, including during winter months. Composite and PVC materials perform well in cold-weather installation — unlike wood, which can be brittle and difficult to fasten in freezing temperatures. Winter building often offers shorter lead times and allows you to have a brand new deck ready for spring entertaining. We take appropriate precautions for frozen ground conditions when installing footings.

How long does a composite or PVC deck last in Colorado?

Premium composite decks from manufacturers like Trex and Fiberon are engineered to last 25 to 30+ years with minimal maintenance. PVC decking from TimberTech AZEK and Wolf can last 50+ years, with Limited Lifetime structural warranties and 50-year fade and stain warranties backing that longevity claim. Compare that to a wood deck in Colorado, which typically needs significant repairs or full replacement within 10 to 15 years due to rapid freeze-thaw cycles, heavy wet snowfall, and intense high-altitude UV radiation.

How long does it take Weatherguard to build a deck in Northglenn?

Most residential deck projects in Northglenn are completed within 3 to 10 business days of on-site construction, depending on the deck's size, complexity, and weather conditions. A straightforward platform or single-level deck can often be finished in under a week. Multi-level designs with pergolas, lighting, and custom railings may take 7 to 14 days. We provide a detailed construction timeline during your estimate appointment.

Why does Weatherguard use Owens Corning structural lumber for deck framing?

The #1 cause of deck failure in Colorado is structural rot in the ledger board, posts, and stair stringers — the critical components that hold your entire deck up. OC Lumber is rotproof, rustproof, and rated for underwater contact — engineered to protect against what wood and steel simply cannot. We use it as our standard for ledger boards, posts, and stair stringers on every deck we build in Northglenn. For homeowners who want the ultimate structural package, we also offer a full OC Lumber frame upgrade.
