As a siding supplier in Waukesha, WI, we understand the importance of strength, efficiency, and low maintenance. Our vinyl siding products are chosen for their ability to perform in cold winters, wet springs, and hot, humid summers—all while enhancing your home’s exterior.

Vinyl Siding That Stands Up to Waukesha Weather

We carry Sequoia Select vinyl siding, one of the most trusted siding systems in the industry. It’s engineered for stability and durability, featuring a .046-inch panel thickness for horizontal profiles and .050-inch for vertical Board and Batten. This thickness helps prevent panel distortion, sagging, and cracking.

The siding includes a full nailing hem and secure interlocking system that makes installation quick and ensures long-term hold, even during strong wind or heavy snow.

Woodgrain Finish with Modern Performance

Sequoia Select offers a realistic cedar-style texture with a soft matte finish that replicates the look of painted wood. The ¾-inch butt height creates deep shadow lines that give your exterior a refined, dimensional appearance.

The Advantage Lock system helps the siding remain flat and aligned, even through Waukesha’s freeze-thaw cycles. Available profiles include Double 4 inch Clapboard, Double 5 inch Dutch Lap, and vertical Board and Batten to suit a wide range of home styles in the area.

Vinyl Siding Colors That Suit Waukesha Homes

Waukesha is known for its architectural diversity, from historic homes to modern subdivisions. Our vinyl siding color palette reflects that range, offering everything from subtle neutrals like Almond, Linen, and Sandstone to dramatic shades like Iron Ore, Midnight Surf, and Dark Drift.

ChromaTrue fade protection ensures your chosen color stays rich and vibrant despite years of sun, moisture, and seasonal wear.

Insulated Siding for Energy Savings and Comfort

We also offer Sequoia Select EnFusion, an insulated vinyl siding solution ideal for homeowners looking to improve energy efficiency. With rigid foam insulation fused to every panel, EnFusion reduces thermal transfer, improves indoor temperature control, and adds resistance to impact and noise.

It’s a smart upgrade for both older Waukesha homes and new construction projects that prioritize performance and comfort.
