Local craftsmanship, start to finish
Jesus Rincon has spent more than ten years in the trade, and Capitol Decks is owned and operated right here in Sun Prairie. Every 4-season rooms project starts with a free on-site visit, a written itemized estimate, and a clear schedule — then a crew that shows up, cleans up, and walks the finished job with you.
We handle permits with Sun Prairie, Madison, and Dane County offices, build to current code, and work in English or Spanish. Ask about how 4-season rooms pairs with deck construction for a complete outdoor living space.
