Three-Season Sunrooms
Extend your outdoor living season with an affordable, comfortable three-season sunroom.

A three-season sunroom gives you the perfect middle ground between a basic screen room and a fully insulated four-season addition. You get protection from bugs, dust, and wind, plus enough temperature control to use the space comfortably from spring through fall. For many Hesperia homeowners, this is the sweet spot that provides maximum value without the higher cost of full climate control.
What Is a Three-Season Sunroom
Think of a three-season sunroom as an upgraded patio enclosure. It has solid walls and a roof like your house, plus plenty of windows and doors for ventilation. The difference from a four-season room is that it does not have full insulation or integrated heating and cooling. This keeps the construction simpler and more affordable.
Your three-season sunroom stays comfortable during mild weather. When Hesperia temperatures are pleasant in spring and fall, you can open windows to catch the breeze. On warm days, ceiling fans and shade treatments help keep things cool. The enclosed design protects you from wind and keeps bugs out, which is a big improvement over an open patio.

Best Uses for Three-Season Sunrooms
Three-season sunrooms work great as casual living spaces where you want that indoor-outdoor feeling. Many of our Hesperia customers use them as morning coffee spots, reading nooks, or entertainment areas for hosting friends and family. They are perfect for activities where you want natural light and a view of your yard but still need protection from the elements.
You can furnish your three-season sunroom with comfortable outdoor or indoor furniture. Add plants to create a garden room feel. Set up a dining table for meals with a view. Or create a relaxing lounge space with sofas and entertainment. The enclosed structure protects your furniture from weather damage much better than an open patio would.
How We Build Three-Season Sunrooms
Construction of a three-season sunroom is more straightforward than a four-season room, which helps keep costs down and speeds up the project timeline. We start with a solid foundation, usually a concrete slab or deck, depending on your home and preferences.
Frame and Structure
We use durable aluminum or vinyl framing systems designed specifically for sunrooms. These materials stand up well to our Hesperia weather and require minimal maintenance. The frame attaches securely to your house and sits on the prepared foundation.
Windows and Roof
We install plenty of windows to maximize natural light and views. You can choose sliding windows, double-hung windows, or a combination based on how you want to control ventilation. The roof can be solid with a finished interior, glass panels for maximum light, or a combination. We help you choose based on your priorities for light, temperature control, and budget.
Finishing Touches
We add electrical service for lights, outlets, and ceiling fans. The floor finish depends on your foundation choice. We can leave a stained concrete floor, add tile, or install other flooring to match your style. We also make sure drainage is proper so water flows away from your sunroom and house.
Should You Choose Three-Season or Four-Season
The choice between a three-season and four-season sunroom comes down to how you plan to use the space and your budget. A three-season room costs significantly less because it does not need insulation, HVAC work, or the same level of weatherproofing. If you mainly want a comfortable outdoor space for pleasant weather and do not need climate control year-round, a three-season sunroom gives you great value.
Here in Hesperia, we do have quite a few months of comfortable weather where a three-season room works perfectly. Spring and fall are ideal. Even winter days can be pleasant with the warming effect of the sun through the glass. Summer might be too warm without air conditioning, but many homeowners are fine with that trade-off given the cost savings.
