Three-Season Rooms

A three-season room gives you the best of both worlds—the feel of being outdoors with the comfort and protection of an enclosed space. Usable from early spring through late fall, a well-built three-season room extends your living space and adds real value to your home. Each room is custom designed to complement your existing home and outdoor area and built using quality materials chosen to hold up through years of use and changing weather.

Patio Enclosures and Screened Rooms

Not every project requires full enclosure. A screened room or patio enclosure is a cost-effective way to enjoy your outdoor space without the bugs, wind, or rain. Deck Company builds screened rooms and patio enclosures that are custom fitted to your existing deck, patio, or porch—giving you a comfortable, open-air space you can actually use and enjoy.

Frequently Asked Questions

  • What Is the Difference Between a Screened Room and a Three-Season Room?

    A screened room uses screen panels to keep out insects while keeping you open to the breeze and fresh air. A three-season room goes further with solid windows or panels that provide protection from wind, rain, and cooler temperatures—extending your usable season well into the fall.

  • Can You Enclose an Existing Deck or Porch?

    Yes. Many of our patio enclosure and three-season room projects are built around existing decks and porches. Our team will assess your current structure and design an enclosure that integrates cleanly with what is already there.

  • Do You Handle Both Residential and Commercial Projects?

    Yes. Deck Company serves both residential homeowners and commercial customers throughout the Fox Valley area and surrounding counties.

  • What Materials Do You Use for Three-Season Rooms?

    We build with treated lumber, natural cedar, and maintenance-free composite materials, available in a variety of finishes. Our team will help you choose the right combination for your space, your style, and your long-term maintenance preferences.
