Custom-Built Comfort and Protection
Our screened porches and sunrooms are tailored to fit your home’s architecture and your lifestyle. We use durable aluminum framing, composite decking, and insect-resistant screens designed to withstand wind and snow. For year-round comfort, our four-season sunrooms feature insulated glass, climate control compatibility, and energy-efficient construction. Each project adds value, comfort, and usable living space to your home.
Whether you want an airy screened porch for summer evenings or a climate-controlled sunroom for all seasons, we’ll design the perfect addition for your home. Our team manages everything—from permitting and foundation work to electrical and finishing details—ensuring a seamless experience from start to finish.

From Grand Forks to Bismarck, we design each enclosure to perform in harsh conditions. We use reinforced framing, triple-sealed windows, and weatherproof connectors to keep your space comfortable and secure. Our construction meets all state and local building codes for snow loads and wind resistance. Whether you’re replacing an old screened porch or adding a new sunroom, our team builds each project with precision and care.

Every porch and sunroom we build is engineered for performance in the Upper Midwest’s demanding climate. We use structural aluminum and pressure-treated framing rated for heavy snow loads and strong gusts. Windows and doors include thermal breaks and weather stripping to reduce heat loss during North Dakota winters. The result: a secure, comfortable space you can use through every season.
Our sunrooms and enclosed porches use energy-efficient materials that balance comfort and style. Insulated glass reduces heat transfer, keeping the room cooler in summer and warmer in winter. Choose from custom window grids, skylights, and ceiling finishes to match your home’s design. Whether you prefer rustic wood tones or sleek modern finishes, every project is designed to blend seamlessly with your home’s existing structure.
