Sunrooms — 3-Season + 4-Season Living Space

Add bright, usable space that feels connected to the outdoors — without sacrificing comfort.

Most sunroom problems come from heat gain, water intrusion, and poor tie-ins to the existing home. We focus on proper flashing, insulation, and window/roof packages so the room stays comfortable and dry.

Common Sunroom Questions

Fast answers — we’ll confirm details during walk-through.

3-season rooms typically use upgraded windows/roof packages for comfort in mild months. 4-season rooms are built more like conditioned living space (insulation + tighter envelope + HVAC options).

We can coordinate permit documentation as part of scope. Requirements vary by city/county and by whether the room is conditioned.

We focus on correct flashing details, clean transitions, and proper drainage paths (including gutters when needed). Tie-ins are where quality matters most.

Yes—comfort comes from the right glazing (Low-E), insulation (roof/walls), ventilation, shading strategy, and (if needed) a mini-split HVAC.
