Three Season Sunrooms, Screen Rooms and Patio Covers in Carterville, IL
We finished a three season sunroom in Carterville in November 2026. It is a dark bronze aluminum room with sliding glass and screen panels, built under the home's existing roofline, with a transom over the entry door and a pet door built into the door itself. Every frame member, the door and the window frames were fabricated in our Evansville shop, then installed by experienced local professionals.

What the Homeowner Said
"The entire team involved in my project were professional and courteous. Not to mention the speed and skill these guys have. We absolutely love our new sunroom!"

The Carterville Sunroom, Start to Finish
The homeowner had a covered porch on a raised masonry base and wanted it closed in so it could be used from early spring to late fall. We measured the openings and built about 28 feet of wall to those measurements, in bronze to sit against the dark siding, with a 24 inch kick panel along the bottom. The lower wall is the Deluxe insulated version: rigid foam insulation with a beadboard finish panel on the inside, so the room looks finished from the couch and not just from the yard. The door is a 36 by 80 inch bronze storm door with tempered glass. The entry door has a pet door set into its lower panel, so the dog can come and go without anyone holding the door.
The photo below shows that same door and the window frames standing in our shop before they were loaded. Nothing on this room came out of a kit or a catalog size.

Three Season Sunrooms
Our Cranbrook enclosure runs on a sliding glass and screen panel system, so the room opens in May and closes in November. Options include tempered upper and lower transoms, kick panel, glass knee wall and insulated wall. It is a glass enclosure rather than a heated addition, and we do not build four season rooms. See three season sunrooms.
Screen Rooms and Patio Covers
Our screen rooms are aluminum framing with screen from the deck up, in white, clay, bronze, black or brown, with pet screen available. We also build insulated patio covers on a 3 inch insulated panel. See screen rooms and patio covers.
Why Carterville Homeowners Call Us
We are a manufacturer, not a reseller. In business since 1979, veteran owned, fabricating our aluminum framing and enclosure components in our own Evansville shop. Because the parts are made by us, an odd opening is a measurement rather than a special order, and a piece that needs changed gets remade here instead of reordered. Every project is covered by our Limited Lifetime Warranty. See more finished projects on our work.
