Buffalo Deck Construction: Authority Fence & Deck is the premier installer of TimberTech AZEK decks in Buffalo, MN, offering a 100% polymer surface that stays up to 30% cooler than traditional wood or composite. Engineered to handle the heavy snow loads and high lakeside humidity of Wright County.
In Buffalo, where our backyards endure everything from humid 90°F summers near Buffalo Lake to the relentless “Polar Vortex” winters, a traditional wood deck is often a high-maintenance liability. Authority Fence & Deck specializes in transforming Buffalo outdoor spaces with TimberTech AZEK—the premier “capped polymer” decking that offers the rich look of exotic hardwood without the endless cycle of sanding, staining, and rot. Whether you’re looking for a sprawling multi-level deck for entertaining near Lake Pulaski or a cozy, slip-resistant retreat in a newer development like those near Wild Marsh, we provide the craftsmanship and advanced materials to make it a reality.
TimberTech AZEK isn’t your standard composite; it contains zero wood fibers, making it completely immune to moisture damage, mold, and rot. This is a critical advantage for Buffalo homeowners dealing with five-plus months of snow and ice sitting on their deck surfaces, or the persistent moisture of a lakeside property. As a family-owned business serving Wright County for over 30 years, we combine these elite materials with a Lifetime Workmanship Guarantee, ensuring your deck remains a beautiful, solid foundation for your family’s memories for decades to come.

FAQ: TimberTech AZEK & Deck Construction in Buffalo
Do I need a building permit for a deck in Buffalo, MN?
Yes. In the City of Buffalo, a building permit is required for any deck that is attached to a structure or is 30 inches or more above grade. Authority Fence & Deck handles the permit process for you, coordinating with the Buffalo Building Department to ensure your structural plans, footings, and railings are 100% code-compliant.
Why is TimberTech AZEK better than composite for Buffalo?
Standard “composite” decks are a mix of wood fibers and plastic. In Minnesota’s extreme freeze-thaw cycles, those wood fibers can absorb moisture, leading to swelling, mold, and internal breakdown—especially in high-humidity areas near Buffalo Lake. AZEK is 100% PVC (polymer), meaning it absorbs zero moisture. It won’t rot, splinter, or peel, even after a record-breaking Wright County winter.
Does AZEK decking get hot in the summer?
All outdoor surfaces get warm, but AZEK is engineered with Alloy Armour Technology, making it up to 30% cooler to the touch than competing composite brands. This makes it a far safer and more comfortable choice for bare feet, children, and pets on a hot July afternoon in an open Buffalo backyard.
How far must a deck be from the property line in Buffalo?
Setback requirements vary by zoning district and lot type (interior vs. corner vs. lakeshore). Typically, decks cannot encroach into required side or rear yard setbacks. Shoreland rules also apply for waterfront yards on Lake Pulaski or Buffalo Lake. We verify your specific property irons and setbacks during our planning phase to ensure your deck is placed legally.
How deep are the deck footings in Buffalo?
For attached decks, building codes require footings to reach below the frost line. Because of the heavy clay soil and deep frost lines in Wright County, Authority Fence & Deck typically digs 42 to 60 inches deep for every footing. This ensures a rock-solid foundation that won’t “heave” or pull away from your home during a hard freeze.
Is TimberTech AZEK slippery when wet?
No. In fact, AZEK features some of the best slip-resistance ratings in the industry. Its non-porous surface and textured grain make it an ideal choice for lakeside properties, pool surrounds, and homes where morning dew or splashing is common.
Can you build a deck over an existing patio?
Yes, we can often “deck over” an existing concrete patio using a specialized sleeper system or a low-profile framing plan, provided the height and drainage meet code. This is a popular way to upgrade an old concrete pad into a luxury AZEK living space.
What kind of maintenance does an AZEK deck require?
Forget the power washers and the $500-a-year staining bills. 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 TimberTech AZEK?
TimberTech provides an industry-leading Limited Lifetime Product Warranty and a 50-Year Fade & Stain Warranty. Authority Fence & Deck backs every installation with our own Lifetime Workmanship Guarantee.
How long does a typical deck replacement take?
Most residential deck projects in Buffalo are completed in 1 to 2 weeks, depending on the size and complexity. We work efficiently to minimize the disruption to your backyard so you can start enjoying your outdoor retreat as quickly as possible.
Do you handle the utility marking?
Yes. Safety is our priority. Before we dig any footings in Buffalo, we coordinate with Gopher State One Call (811) to have all underground gas, electric, and water lines professionally marked.
Can I choose a color that looks like real wood?
Absolutely. The TimberTech AZEK Vintage Collection and Landmark Collection feature highly realistic wood grain textures and variegated colors that mimic premium hardwoods like Ipe or Mahogany, but without the maintenance.
