Room Addition in Mt Prospect, IL

B&C Remodeling adds real square footage to homes in Mt Prospect, IL without making the new space feel tacked on. We handle everything from design and permits through foundation work and finishes so the addition looks and feels like it was always there. If your family has outgrown your home, a room addition is often smarter than moving.

Why Choose Us for Room Addition

We're a family-owned construction company with over 20 years building in Mt Prospect, IL and the surrounding NW Suburbs. We've done enough room additions to know where projects stall โ€” permit delays, foundation surprises, mismatched trim โ€” and we plan for those problems before they hit your timeline or your budget.

New additions only work long-term when the structural and mechanical connections are done right. We tie into your existing framing, electrical, HVAC, and plumbing the correct way. When the job is done, the new space matches your home's style and functions like part of the original build.

How We Work

We start with a site visit at your home in Mt Prospect, IL to measure, talk through your goals, and flag any constraints. From there we put together a design, pull the permits, and manage every trade from excavation through the final coat of paint. You get one point of contact throughout, and we don't consider the job done until the addition passes final inspection and you're happy with what you see.

Room Addition in Mt Prospect, IL

Building in Mt Prospect, IL means working with Illinois winters, and that matters a lot for room additions. Frost depth here runs around 42 inches, so footings have to go deep enough to stay stable through freeze-thaw cycles. We also account for the weight of heavy snow loads when we size the roof framing on any new addition. Skipping those details early creates cracked foundations and sagging rooflines a few years down the road. We've seen the damage that comes from cutting those corners, and we don't cut them.

New Additions That Match Your Existing Home

A lot of contractors can frame a box and call it an addition. What's harder is making new additions blend with a home that was built 30 or 40 years ago. We match rooflines, siding profiles, window styles, and interior trim so the transition from old to new is invisible.

That matters for resale value and for how the space actually feels to live in.

Room Additions for Growing Families

Most of our room addition projects in Mt Prospect, IL come from families who need a bedroom, a home office, or a larger living area and don't want to leave the neighborhood they're in. We've built additions ranging from a single bedroom over a garage to full two-story expansions. Whatever size you need, we scope it honestly and build it to last.

Common Questions

How long does a room addition take in Mt Prospect, IL?
Most room additions run 8 to 16 weeks from permit approval to final walkthrough. The range depends on the size of the addition and how complex the foundation and mechanical work is. We give you a project schedule before we break ground so you know what to expect.
Do you handle permits for room additions in Mt Prospect, IL?
Yes. As a licensed construction company, we pull all required permits through the Village of Mt Prospect. We also schedule and manage every inspection so you don't have to track that yourself. The addition won't be finished until it's fully approved.
Can a room addition connect to my existing kitchen or bathroom?
It can, and we handle those connections in-house. If you're also thinking about updating your existing kitchen or bathroom while we're already on site, ask us about our kitchen remodeling and bathroom remodeling services. Bundling work saves time and often reduces overall cost.
