Four-Season Sunrooms
Year-round comfort meets natural light with our fully insulated four-season sunrooms.

A four-season sunroom gives you the best of both worlds. You get all the natural light and outdoor views of a patio, but with the comfort and climate control of your main living space. Here in Hesperia, CA, where we experience hot summers and cool winters, a four-season sunroom lets you enjoy your outdoor space no matter what the weather brings.
What Makes a Four-Season Sunroom Different
The main difference between a four-season sunroom and other types comes down to insulation and climate control. Your four-season sunroom is built just like the rest of your home, with proper insulation in the walls and roof. This means you can heat it in winter and cool it in summer without losing energy or comfort.
We use thermally broken aluminum framing that prevents heat transfer, double or triple-pane insulated glass, and proper sealing throughout. This creates a space that stays comfortable year-round while keeping your energy bills reasonable.

Perfect for Hesperia Weather
Hesperia gets plenty of sunshine, which is perfect for a sunroom. But we also deal with summer temperatures that can reach over 100 degrees and winter nights that drop below freezing. A three-season room would be too hot in July and too cold in January. That is where a four-season sunroom makes sense for your home.
Your four-season sunroom becomes true living space. You can use it as a home office, dining room, playroom, or just a comfortable spot to relax with a book. Because it is climate-controlled, you do not have to worry about it sitting empty half the year like some outdoor spaces do.
How We Build Your Four-Season Sunroom
Building a four-season sunroom requires more planning than a simpler structure. We start by evaluating your home and discussing how you want to use the space. This helps us determine the right size, layout, and features for your needs.
Foundation and Structure
We typically build on a concrete foundation, just like your house. This provides a solid, level base and proper drainage. The framing uses thermally broken aluminum or insulated vinyl systems that look great and perform well in our climate.
Glass and Insulation
We install high-performance insulated glass that reduces heat gain in summer and heat loss in winter. The roof system includes proper insulation and ventilation. You can choose a glass roof for maximum light or an insulated solid roof with skylights for better temperature control.
Climate Control Integration
We work with HVAC professionals to extend your home heating and cooling system into the sunroom, or we can install a separate system if that makes more sense for your situation. We also add electrical service for lighting, outlets, and any other features you want.
Investment and Value
A four-season sunroom costs more than a three-season room or screen enclosure because of the additional construction required. But you are getting actual living space that you can use every day of the year. Many homeowners find that a custom sunroom addition provides better value than other home expansion options because you get more natural light and outdoor connection than a traditional room addition.
The project typically takes two to four weeks depending on size and complexity. We handle all permits and inspections to make sure everything meets local building codes. When we are done, you will have beautiful new living space that feels like part of your home.
