Colonial Window & Door has served homeowners throughout Seminole, Orange, and Volusia counties since 1996. Free in-home estimates — we come to you.
Colonial Window & Door is a family-owned company based in Lake Mary, FL. For nearly three decades, we've been installing replacement windows and doors for homeowners across Seminole, Orange, and Volusia counties — from Sanford in the north to Orlando in the south. Tom measures every job himself and works with the same trusted installation crew he's relied on for years. No call centers, no runaround. If you're in Central Florida, there's a good chance we serve your neighborhood. See our Lake Mary service page for more detail on our home area, or browse the cities below.
Lake Mary is where we're based, and it's where we do a lot of our work. We've installed replacement windows, sliding glass doors, and entry doors in neighborhoods throughout the 32746 zip code.
