Custom Sunroom Additions in Genesee County, MI

Experience the Outdoors, All Year Round

Imagine enjoying a snowy Michigan morning with a hot cup of coffee, surrounded by floor-to-ceiling views of your backyard—all while staying perfectly warm and comfortable. At Genesee Remodeling, we specialize in high-end sunroom additions that bridge the gap between your home’s interior and the beauty of the outdoors.

Whether you are looking for a breezy summer retreat or a fully insulated year-round living space, our team designs and builds custom sunrooms that match your home’s architecture and your family’s lifestyle.

Choose Your Season: 3-Season vs. 4-Season Rooms

In Mid-Michigan, the “right” sunroom depends on how you plan to use it. We offer two primary options tailored to our local climate:

1. Four-Season Sunrooms (Year-Round Living)

Our 4-season rooms are true home extensions. They are built with the same structural integrity as a traditional room addition but are optimized for maximum glass and light.

  • Fully Insulated: Thermally engineered frames and double-pane, Low-E glass.

  • HVAC Integrated: Connected to your home’s heating and cooling for comfort in January and July.

  • Usage: Perfect for a home office, a bright dining area, or a secondary family room.

2. Three-Season Sunrooms (Seasonal Retreats)

Designed for use from early spring through late fall, these rooms provide a cost-effective way to enjoy fresh air without the hassle of Michigan mosquitoes or unpredictable rain.

  • Breezy & Open: Often features high-quality screen systems or single-pane glass.

  • Affordable Luxury: No need for full HVAC or heavy-duty insulation, making it a faster, budget-friendly build.

  • Usage: Ideal for alfresco dining, morning yoga, or a dedicated plant sanctuary.

Frequently Asked Questions

Yes. Since a sunroom is a structural addition to your home, it requires a building permit to ensure it meets Michigan’s safety codes and local zoning requirements. Whether you are in Grand Blanc, Fenton, or Davison, Genesee Remodeling handles the entire permitting process for you, including architectural drawings and required inspections.

If you choose a Four-Season Sunroom, absolutely! We build these with thermally engineered frames, double-pane Low-E glass, and full insulation. Most importantly, we integrate them into your home’s existing HVAC system so the room stays at 70°F even when there is two feet of snow outside. Three-season rooms, however, are generally intended for use from April through October.

Yes, significantly. A 4-season sunroom adds to your home’s official heated square footage, which directly increases the appraisal value. Even a 3-season room increases “curb appeal” and marketability, as sunrooms are one of the most requested features for homebuyers in Mid-Michigan looking for a connection to nature without the bugs and wind.

Once permits are approved and materials are delivered, the actual on-site build usually takes between 2 to 4 weeks. However, the “pre-construction” phase (designing, engineering, and city approval) can take an additional 4–6 weeks. We provide a guaranteed timeline before we break ground so you know exactly when your new sanctuary will be ready.
