Homeowners across Andover, Minnesota are replacing aging wood decks with premium composite and PVC alternatives — and for good reason. The pressure-treated lumber on most Minnesota decks lasts 10–15 years before rot, insects, and moisture compromise the structural integrity. By year 12, most wood decks have soft spots, wobbly railings, and deteriorating stair stringers that make them unsafe for your family.
Weatherguard Construction builds decks differently. We start with Owens Corning structural lumber for the three components that fail first: the ledger board (where the deck attaches to your house), posts, and stair stringers. OC Lumber is rotproof, rustproof, and rated for underwater contact — engineered to protect against what wood and steel simply cannot. Combined with proper frost-depth footings and code-compliant ledger flashing, our structural approach eliminates the #1 cause of deck failure in the Midwest. Want the ultimate build? Ask about upgrading your entire deck frame to OC Lumber.
With average winter lows dipping below -10°F and summer highs regularly exceeding 90°F, Minnesota decking materials must withstand a temperature range of over 100 degrees annually. Add heavy snow loads, spring ice melt, and summer storm damage to the equation, and it becomes clear why material selection matters more here than almost anywhere else in the country.
From multi-level entertainment decks with integrated lighting and privacy walls to simple platform decks that connect your home to your backyard, Weatherguard handles every step — permits, footings, framing, decking, railing, and final cleanup.
PVC Decking: Ultimate Durability for Minnesota Weather
PVC (polyvinyl chloride) decking represents the pinnacle of low-maintenance outdoor living technology. Unlike composite — which contains wood fibers — PVC boards are made entirely from engineered polymer, making them completely impervious to moisture absorption. For Andover homes subjected to sub-zero temperatures, heavy snowfall, and persistent ice accumulation, PVC decking eliminates any risk of swelling, warping, or rot caused by trapped moisture freezing inside the board.

Weatherguard is a certified TimberTech installer, giving Andover homeowners access to the complete AZEK Advanced PVC lineup with enhanced warranty coverage:
- Vintage Collection: The ultra-premium tier featuring sought-after hardwood aesthetics with a refined wire-brushed finish and multitonal color blending. Colors include Weathered Teak, Mahogany, Coastline, English Walnut, Cypress, and Dark Hickory. Backed by a Limited Lifetime product warranty and 50-year fade and stain warranty.
- Landmark Collection: Crosscut cathedral grain styling that replicates the look of white oak and walnut with a sophisticated matte finish. Available in American Walnut, French White Oak, Boardwalk, and Castle Gate.

Composite vs. PVC Decking: Choosing the Right Material for Your Andover 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:
| Feature | Composite Decking | PVC Decking |
|---|---|---|
| Composition | Wood fibers + recycled plastic | 100% engineered polymer |
| Moisture Resistance | Excellent (capped shell protection) | Superior (zero moisture absorption) |
| Weight | Heavier (similar to wood) | Lighter (easier to handle) |
| Heat Retention | Moderate (can get warm in direct sun) | Lower (stays cooler underfoot) |
| Scratch Resistance | Very good | Excellent |
| Price Range | $$ to $$$ | $$$ to $$$$ |
| Best Warranty | 25-year to Limited Lifetime | Limited Lifetime + 50-year fade/stain |
| Ideal For | Budget-conscious upgrades, ground-level decks | High-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.
Composite Decking: The Smart Choice for Andover 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 Andover 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.

Understanding Deck Warranties: What Andover 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 Andover 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 Andover Property
No two Andover 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 Minnesota:
- 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 Andover 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.
Deck Maintenance in Minnesota: 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.
Structural Integrity: Why Most Andover Decks Fail — And How We Prevent It
The most expensive part of your deck isn't the surface boards — it's the structural framing underneath. And it's the part that most contractors cut corners on. Standard pressure-treated lumber starts absorbing moisture and deteriorating the moment it's installed. In Minnesota, where sub-zero temperatures, heavy snowfall, and persistent ice accumulation create relentless freeze-thaw cycles, that process accelerates dramatically. Within 10–15 years, the ledger board, posts, and stair stringers on a typical Andover deck are soft, splitting, and structurally compromised.
The Three Points of Failure — And How OC Lumber Solves Them
- Ledger Board: The ledger board connects your deck to your house. When it rots, the entire deck pulls away from the structure — a catastrophic and dangerous failure. Weatherguard uses Owens Corning structural lumber for every ledger board — rotproof, rustproof, and rated for underwater contact. OC Lumber installs with the same tools and fastener patterns as traditional lumber, combined with self-adhering flashing tape for complete moisture protection.
- Posts: Deck posts transfer the full weight of the structure to the footings. Ground-contact moisture, insects, and freeze-thaw cycling destroy standard PT lumber posts from the inside out. OC Lumber posts are rated for ground and underwater contact, eliminating rot at the critical zone where standard lumber fails first.
- Stair Stringers: Stair stringers carry concentrated loads and are repeatedly stressed by foot traffic. They're also exposed to splashing water and ground-level moisture. OC Lumber stringers are rotproof and rated for ground contact, with proper standoff brackets and blocking between stringers for lateral bracing — eliminating the #1 stair failure point.
Why Owens Corning Structural Lumber?
OC Lumber is engineered to protect against what wood and steel simply cannot. Rotproof, rustproof, and rated for underwater contact in both fresh and salt water. Designed to install like the lumber you use every day — same tools, same trade, same practices. Made to last. We don't offer this as an upgrade or an add-on — it's our standard for every ledger board, post, and stair stringer we install in Andover and across Minnesota.
Optional Upgrade: Full OC Lumber Framing
For homeowners who want the ultimate structural package, Weatherguard offers a full OC Lumber frame upgrade — every joist, beam, rim board, and blocking piece in Owens Corning structural lumber. While our standard build uses OC Lumber for the three components that fail first, a full OC Lumber frame means every piece of structural wood in your deck is rotproof, rustproof, and rated for underwater contact. Combined with properly engineered frost-depth footings and code-compliant ledger connections, our structural approach gives you a deck that will perform for decades, not just years.
