Most decks don't fail because of the surface boards — they fail because of what's underneath. Rotting ledger boards, deteriorating posts, and soft stair stringers are the hidden killers that cause deck collapses, safety hazards, and costly emergency repairs. At Weatherguard Construction, we build every Lakeville deck on a foundation of Owens Corning structural lumber for ledger boards, posts, and stair stringers as our standard — not an upgrade, not an add-on. OC Lumber is rotproof, rustproof, and rated for underwater contact in both fresh and salt water — engineered to protect against what wood and steel simply cannot. This is how we build. Period.
On top of that engineered foundation, we install premium composite and PVC decking from Wolf, TimberTech AZEK, and Trex — materials designed to handle Minnesota's sub-zero temperatures, heavy snowfall, and persistent ice accumulation without the constant staining, sealing, and sanding that wood decks demand. Minnesota's freeze-thaw cycles — where temperatures can swing 60 degrees in a single week — put extraordinary stress on outdoor structures. That's exactly why Weatherguard refuses to cut corners on structural framing — and why we partner with the industry's most advanced decking manufacturers. 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.
Every Weatherguard deck project in Lakeville begins with a complimentary on-site consultation where we assess your property, inspect your existing structure (if applicable), discuss your vision, and provide a transparent, all-inclusive estimate. No high-pressure sales tactics, no bait-and-switch pricing — just honest guidance from experienced professionals.
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.
Composite Decking: The Smart Choice for Lakeville 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 Lakeville 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.

The Weatherguard Deck Building Process in Lakeville
We have refined our deck building process over hundreds of successful projects to deliver a stress-free experience from first call to final walkthrough:
- Complimentary Design Consultation: We visit your Lakeville property, take measurements, discuss your goals and budget, review material options, and identify any site-specific considerations like drainage, grading, utilities, or setback requirements.
- Custom Design and Proposal: Within days, you receive a detailed proposal that includes a material specification sheet, dimensional drawings, color and railing selections, permit requirements, project timeline, and a fixed-price quote.
- Permitting and Engineering: We submit all required permit applications to your local Lakeville building authority, coordinate any necessary engineering reviews, and schedule inspections — so you never have to deal with the paperwork.
- Demo and Site Preparation: If you have an existing deck, our crew carefully removes it, salvages any reusable hardware, and disposes of all debris responsibly. We then prepare the site for new footings and structural work.
- Foundation and Framing: Using helical piers, diamond piers, or poured concrete footings — depending on your soil conditions and local code requirements — we build a rock-solid structural foundation designed to last a lifetime.
- Decking, Railing, and Finish Work: Your selected composite or PVC boards are installed with hidden fasteners for a clean, screw-free surface. Railings, lighting, skirting, and other enhancements are completed to manufacturer specifications.
- Final Inspection and Walkthrough: We schedule the required building inspection, walk you through your completed deck, explain care and maintenance (hint: there is barely any), and make sure every detail meets your expectations before we consider the project complete.
Built for Minnesota Weather: How Our Decks Handle Minnesota's Extreme Climate
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.
Here is how the materials we install are specifically engineered to handle these challenges:
- Freeze-Thaw Resistance: PVC decking absorbs virtually zero moisture, eliminating the primary cause of cracking and warping during Minnesota's freeze-thaw cycles. Composite boards use capped polymer shells that prevent moisture penetration into the wood-fiber core.
- UV Stability: Premium composites and PVC boards incorporate UV-stabilizing compounds and multi-layer fade-resistant coatings that maintain color vibrancy despite years of direct sun exposure — critical in Minnesota where summer UV can be intense.
- Snow Load Performance: Our structural designs account for Minnesota's maximum expected snow loads, using properly sized joists, beams, and footings that prevent sagging or structural fatigue under heavy wet snow accumulation.
- Thermal Expansion Management: All materials expand and contract with temperature changes. Our installation methods incorporate manufacturer-specified gapping and fastening patterns that allow for thermal movement without buckling, cupping, or unsightly gaps.
- Mold and Mildew Prevention: The polymer caps and shells on our decking materials create a non-porous surface that resists mold and mildew growth — a common problem with wood decks in Minnesota's humid summer months.
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 Lakeville 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.

Structural Integrity: Why Most Lakeville 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 Lakeville 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 Lakeville 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.
Understanding Deck Warranties: What Lakeville 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 Lakeville design consultants walk you through every warranty detail during your estimate appointment so you understand exactly what protection your investment carries before you commit.
