As a siding supplier in Madison, WI, we know what it takes to build exteriors that stand up to Wisconsin’s unpredictable weather. Our siding products are engineered to resist snow, rain, and UV exposure while maintaining their structure and color for years.

Vinyl Siding Made for Madison’s Seasons

We carry Sequoia Select vinyl siding, a premium-grade product line built for strength and visual appeal. With .046-inch panel thickness for horizontal profiles and .050-inch for vertical Board and Batten, this siding offers rigid performance and holds up to harsh temperature swings and wind exposure.

Its secure locking system and full nailing hem make installation fast and stable. Whether you’re replacing siding on an older home near Lake Monona or finishing a new build on the west side, this siding performs reliably in any neighborhood.

Realistic Wood Appearance with Built-In Stability

Sequoia Select siding offers the look of painted wood without the upkeep. A matte finish and deep cedargrain texture give it an authentic, natural look, while the deep ¾-inch butt height adds visual depth and bold shadow lines.

The Advantage Lock system helps prevent panel movement and warping during freeze-thaw cycles, a must-have in Madison’s climate. Available profiles include Double 4 inch Clapboard, Double 5 inch Dutch Lap, and Board and Batten styles, allowing for a wide range of design flexibility.

Color Choices for Every Home Style in Madison

Madison’s neighborhoods include everything from historic bungalows to modern lakefront homes. Our color selection covers all preferences, from soft, neutral tones like Linen and Sandstone to dramatic designer shades like Midnight Surf, Iron Ore, and Dark Drift.

All colors feature ChromaTrue protection, which helps prevent fading and color distortion caused by intense sunlight or wet conditions. Whether you’re modernizing a ranch in Maple Bluff or working on a custom build in Sun Prairie, we’ll help you find a siding color that fits your vision.

Boost Efficiency with Insulated Vinyl Siding

We also offer Sequoia Select EnFusion, an insulated vinyl siding system that enhances thermal performance and comfort. Each panel includes rigid foam insulation to create a strong thermal barrier, helping to reduce heating and cooling costs throughout the year.

This insulated option is ideal for older homes or anyone seeking greater energy efficiency without compromising exterior style. It also improves impact resistance and sound reduction—perfect for homes near busy roads or in dense neighborhoods.
