Premium Vinyl Siding for Downers Grove Homes

We carry Sequoia Select vinyl siding, a top-rated siding line built for strength, weather resistance, and clean aesthetics. With panel thicknesses of .046 inches for horizontal profiles and .050 inches for Board and Batten, this siding offers rigidity that resists buckling, warping, and blow-offs.

Sequoia Select also features a full nailing hem and reinforced locking system to ensure strong panel-to-wall attachment. Whether you’re updating a century-old house or installing siding on a new development near Belmont Road, we provide reliable materials you can count on.

Built for Suburban Conditions and Architectural Style

Downers Grove homeowners need siding that looks great and performs through every season. Sequoia Select is built for both. Its Advantage Lock system stabilizes each panel and reduces shifting caused by wind or temperature fluctuations.

The siding has a natural cedar-grain texture and matte finish that mimics the look of freshly painted wood. The deep ¾-inch butt height adds visual depth and dimension to the exterior, creating a polished finish that complements both traditional and modern homes.

Available profiles include Double 4 inch Clapboard, Double 5 inch Dutch Lap, and vertical Board and Batten, perfect for mixing styles and adding architectural interest.

Siding Colors That Match Downers Grove’s Character

Downers Grove neighborhoods range from historic to brand new, and we offer siding colors to suit every style. Choose from soft, timeless tones like Pearl, Sandstone, and Almond, or go bold with deep hues like Iron Ore, Midnight Surf, and Dark Drift.

All colors are backed by fade-fighting ChromaTrue technology to ensure they remain vibrant and consistent through years of sun exposure and seasonal change.

Whether you’re designing a high-end custom home or replacing existing siding, we can help you find the ideal color to match your vision and exterior features.

Insulated Siding That Enhances Energy Performance

For added comfort and efficiency, we also supply Sequoia Select EnFusion insulated siding. This product integrates a layer of rigid foam behind the vinyl panel to improve energy retention, reduce noise, and increase impact protection.

Insulated siding is a smart choice for Downers Grove homeowners looking to upgrade the thermal envelope of their homes without compromising on exterior appearance. It also works well for contractors aiming to meet higher energy standards or build greener homes.
