St. Michael Deck Construction: Authority Fence & Deck specializes in high-end, maintenance-free AZEK decks for St. Michael families, providing a splinter-free and slip-resistant surface for STMA backyards. Includes a 50-year fade and stain warranty.
In St. Michael, your home is part of a community that values high-quality curb appeal and active outdoor living. But with our heavy clay soil and the “STMA wind” that sweeps across open lots, a traditional wood deck can quickly become a maintenance nightmare of warped boards and peeling stain. Authority Fence & Deck specializes in transforming St. Michael backyards with TimberTech AZEK—the premier “Advanced PVC” decking that offers the rich look of premium hardwood without ever requiring a sander or a paintbrush.
Whether you are expanding your entertainment space in The Highlands or building a safe, slip-resistant retreat in Vista Pointe, we provide the localized expertise to navigate St. Michael’s strict building codes. Unlike standard composites that contain wood fibers, our TimberTech AZEK decks are 100% polymer, making them completely immune to the rot and mold that often plague decks in high-moisture Minnesota seasons. As a family-owned team since 1994, we combine these elite materials with a lifetime workmanship guarantee, ensuring your deck remains a solid, beautiful investment for decades.

FAQ: TimberTech AZEK & St. Michael Deck Building Codes
Do I need a building permit for a deck in St. Michael, MN?
Yes. St. Michael requires a building permit for any deck that is attached to the home or any detached deck that is more than 30 inches above grade. Authority Fence & Deck manages the permit application process for you, ensuring your plans meet the 2026 Minnesota Residential Code and St. Michael’s specific zoning ordinances.
What are the deck setback requirements in St. Michael?
Generally, decks must meet the same setbacks as your primary residence. For most St. Michael residential zones, this means a 25-foot rear yard setback and a 10-foot side yard setback. However, some PUD (Planned Unit Developments) have specific exceptions. We verify your exact property pins and HOA rules during our consultation to ensure your deck is placed legally.
Why is TimberTech AZEK better for St. Michael’s heavy clay soil?
St. Michael is known for clay that holds moisture and causes significant “frost heave.” Traditional wood-composite decks can swell or warp when sitting on this damp ground. AZEK contains zero wood fibers, meaning it won’t absorb moisture or rot. We pair this with our signature 42 to 60-inch deep footings to anchor your deck below the frost line, keeping it level and solid for a lifetime.
How deep must the footings be for a St. Michael deck?
St. Michael code requires footings to be a minimum of 42 inches deep. We often dig to 60 inches to ensure your deck is anchored deep into the stable soil layers, providing a rock-solid foundation that won’t shift or “pop” during the spring thaw.
Does TimberTech AZEK stay cool for bare feet?
Yes. AZEK is engineered with CoolTouch™ technology, allowing it to stay up to 30% cooler to the touch than traditional composite decking. This is a critical safety feature for St. Michael families with children and pets on those hot July afternoons.
Is the decking slippery when wet?
No. In fact, AZEK offers some of the highest slip-resistance ratings in the industry. Its non-porous surface and textured grain make it a safe choice for pool surrounds or high-traffic areas, even during rainy Minnesota springs.
What kind of maintenance does an AZEK deck require?
Virtually none. Forget the annual staining and power washing. A simple rinse with a garden hose and mild soap once or twice a year to remove dust or pollen is all you need to keep your AZEK deck looking brand new.
What is the warranty on my new deck?
TimberTech provides an industry-leading Limited Lifetime Product Warranty and a 50-Year Fade & Stain Warranty. Authority Fence & Deck backs every project with our own Lifetime Workmanship Guarantee.
Can I build a deck over a utility or drainage easement?
St. Michael generally prohibits permanent structures within easements. We help you identify these areas on your property survey to ensure your deck is placed safely to avoid future issues with utility companies or city drainage.
How long does a typical deck replacement take?
Most residential deck projects in St. Michael are completed in 1 to 2 weeks. We work efficiently and maintain a clean job site so you can start enjoying your new outdoor space as quickly as possible.
Do you handle the utility marking (Gopher State One Call)?
Yes. Before we dig any footings, we coordinate with Gopher State One Call to have all underground gas, electric, and water lines professionally marked for safety.
