Vinyl Siding Designed for Janesville Homes

We carry Sequoia Select vinyl siding, known for its strength, long-term performance, and clean, classic finish. Built with .046-inch thickness for horizontal profiles and .050-inch for vertical Board and Batten, this siding holds its shape and resists warping even through extreme temperature swings and heavy winter conditions.

The reinforced locking system and full nailing hem provide reliable attachment to any structure. Whether you’re working on a home in the historic district or finishing new construction on the north side, this siding is a fit for every type of build in Janesville.

Durable Finish with Traditional Curb Appeal

Sequoia Select siding offers a beautiful woodgrain texture with a soft matte finish for the look of painted wood without any of the maintenance. With a ¾-inch butt height, it creates strong shadow lines and adds depth and definition to the exterior.

The Advantage Lock system keeps panels aligned, flat, and secure, even during freeze-thaw cycles. Popular styles like Double 4 inch Clapboard, Double 5 inch Dutch Lap, and vertical Board and Batten give you options that match a range of home styles found across Janesville’s neighborhoods.

Siding Colors That Match Janesville’s Character

Janesville’s housing styles range from classic farmhouses and Victorians to more modern developments, and we offer vinyl siding colors to suit them all. Choose neutral tones like Pearl, Sandstone, or Wicker for a timeless look, or explore designer shades like Iron Ore, Storm, and Midnight Surf for bold contrast and modern flair.

Our colors are backed by ChromaTrue fade protection to ensure long-lasting vibrancy, even after years of sun, wind, and snow. We help contractors and homeowners find the right combination of color and texture to enhance any property.

Insulated Siding for Year-Round Comfort in Janesville

For homeowners who want energy savings and added protection, we also offer Sequoia Select EnFusion. This insulated siding integrates rigid foam backing into each panel, forming a continuous thermal layer that helps reduce heating and cooling costs.

EnFusion siding is ideal for Janesville’s colder months, especially for older homes that need improved insulation. It also adds impact resistance and soundproofing to create a quieter, more comfortable living space.
