Screened-In Porches & Sunrooms in Montana
What We Build And How It Performs
Comfort and Coverage Without Losing the View
Our screened-in porches and sunrooms are fully customized to match your home’s architecture, siding, and lifestyle. Choose a breezy cedar-framed porch with mesh screens, or a fully enclosed sunroom with insulated glass and electric hookups. Every structure is framed to handle Montana’s snow loads, wind exposure, and temperature swings. Whether you’re looking for a seasonal escape or a four-season room, we design it to last and to live in.
Bug-Free, Wind-Free, Snow-Free Outdoor Living
Why Montana Homeowners Choose Enclosed Porches
Montana’s beauty comes with a tradeoff bugs, wind, and weather can cut outdoor time short. Screened-in porches and sunrooms create protected spaces where you can relax, dine, or entertain without worrying about insects, rain, or snow drift. Whether you want fresh air and shade in the summer or a glassed-in room with panoramic views, our builds increase year-round usability and curb appeal.
Keep out mosquitos, wasps, and flies
Shelter from wind, rain, and drifting snow
Create cozy zones for reading, dining, or lounging
Built for Use, Not Just Appearance
Custom Framing, Insulation & Finish Options
Our screened and enclosed structures aren’t flimsy kits they’re framed, insulated, and finished like permanent additions. We use pressure-treated framing, engineered footings, and weather-sealed screens or insulated windows. Walls can be left open-air or built with electrical outlets, lighting, and ceiling fans. If you want a usable outdoor room that feels like part of your home, we’ll build it that way fully integrated and Montana-tough.
Three-Season or Four? You Decide.
Porch and Sunroom Builds That Match Your Needs
Looking for a simple screen room or a fully enclosed sunroom? We build both. Three-season porches offer protection without insulation great for spring through fall. Four-season sunrooms feature double-pane windows, insulated floors, and optional HVAC hookups, giving you a usable room year-round. No matter the style, each project is designed to perform through Montana’s temperature swings, elevation, and snow loads.

Montana Porch & Sunroom FAQs
Have Questions About Porch Enclosures or Sunrooms?
Here’s what homeowners across Montana want to know before enclosing their deck or adding a sunroom:
What’s the difference between a screened porch and a sunroom?
Screened porches have mesh sides for airflow. Sunrooms use glass windows and often include insulation and electricity.
Can a screened porch be upgraded later?
Yes. We can design it for future enclosure if you want to convert to glass down the road.
Do sunrooms require a foundation?
Depending on size and location, yes. We’ll assess and include that in the estimate.
How long does a sunroom project take?
Most builds take 3–6 weeks, including design, permits, and construction.
