A complete installation project
From first conversation to project closeout
The process is built around measured openings, a project estimate, and professional installation.
Start the conversation
Call, text, or use the estimate form. Tell Colonial which windows, sliding doors, or combination you are considering.
Review and measure
A home visit confirms the openings, visible conditions, operating needs, and priorities for the project.
Select the project
Colonial explains applicable styles, configurations, glass, finishes, published ratings, and the project estimate.
Order, permit, and install
Your selected products are ordered. When a permit is required, Colonial prepares and submits the permit paperwork, then coordinates installation and project closeout.
Timing is project-specific.
Product availability, permit review, opening conditions, and project size can affect the schedule. Colonial explains the expected sequence for the actual project instead of promising one universal lead time.
