Home Addition Services in Mt Prospect, IL

We're a family-owned remodeler, not a franchise, so the people who plan your addition are the same ones managing the build. That matters when you're adding square footage to a home you've lived in for years. We've done enough home addition construction in Mt Prospect, IL to know how the village permitting office works, what inspectors look for, and how to keep your family comfortable while the work is going on.

Our crews don't hand off jobs to subcontractors and disappear. We coordinate the framing, insulation, electrical, and finish work under one roof. When the job is done, your new space matches the rest of your home in materials and character. That's the standard we've held for two decades, and it's why most of our calls come from referrals.

Homes in Mt Prospect, IL deal with real Chicago-area winters, and that affects how we approach every home addition we build. Frost depth here runs about 42 inches, so footings for a room addition have to be set well below grade or you'll see movement and cracking within a few years. We also build above Illinois energy code minimums on insulation and air sealing, because a sunroom addition or attic conversion that's drafty in February isn't a livable space. If you're adding a room that connects to your existing HVAC, we check whether your current system can carry the extra load before we close up the walls.

Attic Conversion: Space You Already Own

A lot of Mt Prospect, IL homeowners don't realize how much usable square footage is sitting above their heads. An attic conversion turns that raw space into a bedroom, office, or playroom without touching your yard or your footprint. We assess the existing floor joists, headroom, and roof pitch first, because not every attic is a good candidate without structural work. When it is viable, it's usually the most cost-effective way to add a room to your home.

We handle the stair access, insulation, drywall, and electrical as part of the project. You won't be managing four separate contractors. The finished space ties into the rest of your home's trim and paint, so it reads as part of the original house.

Sunroom Additions for Year-Round Use

A sunroom addition gives you a space that feels like the outdoors without the mosquitoes or the January wind. We build them to be used year-round in the Mt Prospect, IL climate, which means proper insulation, thermal windows, and a heating source that actually keeps up when it's 10 degrees outside. A three-season room costs less upfront but you'll lose it half the year. We'll walk you through both options so you can decide what fits your budget and how you actually live.

Sunrooms also connect to your home's footprint, so design matters. We match the roofline, siding, and trim to your existing exterior so the addition doesn't look like it was bolted on.
