Benefits That Old-Fashioned Wood Siding Can’t Deliver

This siding has the warm appeal of real wood siding, but the performance of a 21st Century, high-tech product. Because it is lightweight and easy to install, it offers an affordability that some other siding options cannot match. It is available in smooth or textured finishes, and in prefinished colors. Or it can be painted in the color of your choice.

Let the experts at United Windows and Siding help you choose siding that will best meet your home’s needs at a cost that fits your budget. Our professional siding installers will install these siding products per manufacturer’s guidelines, so your home will have real “curb appeal” for many years.
