Frequently Asked Questions

How long does window replacement take?

Most homes can have 4–8 windows replaced in a single day. RSI handles removal, installation, insulation, trim, and cleanup.

Are energy-efficient windows worth it?

Yes. ENERGY STAR® windows improve comfort, reduce drafts, and can lower utility bills—especially in Michigan’s variable climate.

How do I know if my windows need to be replaced?

Signs include drafts, condensation between panes, difficulty opening, water intrusion, and higher energy bills.

Do new entry doors improve home security and efficiency?

Absolutely. Modern fiberglass and steel doors provide better insulation, durability, and locking systems than older wood doors.
