Welcome to Metro East Sunrooms
Whether you’re picturing a fully insulated four-season room or a simple screened-in porch for warm summer evenings, we handle the entire process—from design through final installation—so your new space feels like it was always meant to be part of your home.
Why Metro East Homeowners Choose Us
Custom Design for Your Actual Home
No prefab, one-size-fits-all rooms—every sunroom we build is designed around your home’s layout, style, and how you actually plan to use the space.
Built for Illinois Weather, Not Just Nice Days
Between humid summers and cold winters, we choose materials and construction methods that keep your sunroom comfortable and functional year-round.
One Team, Start to Finish
From design consultation to final installation, our crew handles the entire project so you’re not managing multiple contractors.
Real Craftsmanship, Not Just a Kit
We build sunrooms with the same attention to detail as the rest of your home, not a bolted-on afterthought that looks out of place.
Respectful of Your Property While We Build
We protect your landscaping, keep the job site clean, and stay on schedule so the process feels as smooth as the finished room will look.
Our Sunroom & Outdoor Living Services
Custom Sunroom Design & Build
Every great sunroom starts with a design that actually fits how you want to use it, not a generic template pulled off a shelf. We design and build fully custom sunrooms tailored to your home’s architecture and your family’s daily life.
Four-Season Sunrooms
If you want a room you can actually use in July and January alike, a four-season sunroom is the answer. We build fully insulated, climate-controlled sunrooms designed to stay comfortable no matter what the season throws at your property.
Three-Season Sunrooms
Screen Rooms & Enclosures
A porch that’s constantly invaded by mosquitoes isn’t a space you actually want to relax in. We build screened-in enclosures that let you enjoy fresh air and evening breezes without ever swatting away a bug.
Patio Enclosures
An existing patio that never quite gets used enough often just needs to be enclosed to become a genuine extension of your home. We convert open patios into fully enclosed living spaces, adding real function and value without a full addition.
Glass Rooms & Solariums
If natural light is the priority, a full glass enclosure creates a bright, open feel unlike any other addition. We design and build solariums that flood your space with sunlight while maintaining the structural integrity your home needs.
Sunroom Additions
Sometimes what you really need is more square footage, not just a covered patio. We build complete sunroom additions that expand your home’s footprint, increasing both usable living space and long-term property value.
Energy-Efficient Window & Door Systems
A sunroom is only as comfortable as the windows and doors holding the elements out. We install high-performance window and door systems designed for insulation and durability, keeping your sunroom comfortable in every season.
Repairs, Upgrades & Conversions
An older sunroom that’s drafty, damaged, or just outdated doesn’t always need to be torn out and rebuilt. We repair, upgrade, and convert existing sunroom structures to improve comfort, efficiency, and overall appearance.
