Local service from Colonial's home base
Colonial Window & Door is based in Lake Mary and serves replacement installation projects throughout the surrounding Seminole County area. Lake Mary is known for its planned residential communities, but no two openings or project scopes should be treated as interchangeable.
Colonial measures the actual openings, reviews how each window or door needs to operate, and builds the estimate around the home in front of us. That keeps the conversation focused on fit, use, appearance, and the complete installation instead of a one-size product pitch.
A local starting point
Colonial is based in Lake Mary, so homeowners have a Central Florida company with a clearly identified home base.
Whole-project planning
Windows and sliding doors can be reviewed together or as separate installation projects, depending on the home.
Address-specific permitting
Permit requirements are reviewed for the actual project address before installation is scheduled.
