Tree-lined streets, waterfront views, and outdoor living in Mandarin call for a dedicated space to enjoy it all year long. At Screen Enclosures by Colonial Construction, we’ve spent over 25 years helping Northeast Florida homeowners turn underused patios and bare backyard corners into beautiful, functional living spaces. Thinking about glass enclosures and sunrooms in Mandarin, FL? This is where that idea becomes a project with a real plan.
Professional Glass Enclosures & Sun Room Design and Build Services in Mandarin
Mandarin sits along the St. Johns River, and the natural scenery here deserves more than a quick glance through a window. A professionally installed glass enclosure or sunroom gives you a way to stay connected to that scenery without trading comfort for it.
Our glass and sunrooms can withstand Florida’s climate, handling heat, humidity, and the occasional storm without losing their appeal. We work with homeowners in Mandarin to understand how they use their outdoor space before we start talking about materials or layouts.
Some families want a year-round dining room with a garden view. Others want a quiet reading nook that feels open but stays cool. We approach every project with that context in mind.
What our glass enclosure and sunroom services in Mandarin include:
- Full custom design tailored to your home’s existing architecture and your lot’s layout
- Glass wall and roof panel installation using materials rated for Florida weather conditions
- Structural framing that meets local building codes and St. Johns County permit requirements
- Finishing work, including flooring, trim, and detail work that ties the new space into your home
- Clear project timelines with a team that communicates at every stage
Mandarin homeowners also appreciate how a sunroom can add measurable square footage to a home without a full addition. It’s a practical investment that adds daily value well beyond its construction cost.
What’s Included in Our Glass Enclosures & Sun Rooms Design and Build Services
A glass enclosure or sunroom from Colonial Construction isn’t a prefab kit dropped in your backyard. We handle the full process from initial estimate through final walkthrough, and we take pride in what happens in between.
Our process covers:
- Free on-site estimate at your Mandarin property, so we can assess your space and discuss your goals in person
- Permit handling is coordinated with local authorities, so you don’t have to manage that process yourself
- Material selection guidance to help you choose glass types, frame finishes, and ventilation options that fit your lifestyle
- Professional installation carried out by our experienced crew, not subcontractors who don’t know the project history
- Post-installation walkthrough to make sure everything meets your expectations before we call the job done
We also pair sunroom projects with our screen room services when homeowners want to compare options or add complementary outdoor spaces to their property. Some clients in Mandarin choose a glass enclosure on one side of the home and a screened area on another. It’s a combination that works especially well for larger lots.
