We Offer a Range of Siding Materials
One of the most popular siding types is vinyl. Introduced in the early 1960s, vinyl siding has grown in popularity because of its durability, versatility, and ease of maintenance. Vinyl siding is manufactured with polyvinyl chloride and resin, which make it waterproof, impact-resistant, and strong.
In the early days of vinyl siding, color choices were limited to neutrals and pale pastels. New innovations in the manufacturing process have produced a full complement of rich siding colors, such as barn red and forest green. Learn more about our vinyl siding options.
Knox’s Construction installs quality products from CertainTeed and Mastic. With durable, contemporary choices from the industry’s top manufacturers, we offer only the best siding options to improve the exterior of your home.

Advantages of Quality Vinyl Siding for Your South Park Home
Vinyl siding is a popular choice for residential and commercial buildings alike. Here is why so many Allegheny County homeowners choose it.
Low Maintenance
Vinyl requires less maintenance than most manmade cladding materials. It resists heat, cold, mold, and mildew, and it never needs painting, scraping, or sanding like wood.
Durability
Vinyl siding ranks only behind brick and stone for durability and long life. Advances in vinyl chemistry are why many manufacturers now offer lifetime warranties.
Lower Replacement Cost
Compared to wood, vinyl siding costs roughly half as much per square foot, and faster installation saves on labor too.
Increased Home Value
New vinyl siding gives older homes in particular a big lift. Quality vinyl siding in South Park can add considerable value and is an attractive selling point for buyers.
Versatility
Vinyl comes in a wide range of colors, textures, and styles, and it can mimic the look of wood without the upkeep.
Energy Efficiency
Insulated vinyl siding reduces heat transfer through your walls, which can mean lower energy bills and a more comfortable home year round.
Eco-Friendly
Vinyl is recyclable, many manufacturers use recycled content, and its low upkeep means fewer resources spent on maintenance.
