Home Additions & Expansions in Michigan

Q: Do additions require upgrades to HVAC or electrical?

Often yes. We evaluate system capacity up front and design the right upgrades—new runs, panel capacity, or system resizing.

Q: How long does a typical addition take?

Most projects run 8–16 weeks depending on size, complexity, and municipality. We provide weekly schedule updates and photo reports.

Q: Can you match my existing exterior?

Yes. We match siding, shingles, windows, and trim so the addition looks original to your home.

Q: Will we need to move out?

Usually not. We use dust control, safe access, and clean job-site practices to keep your home livable.
