Windows that match your home’s proportions and finish
In a town known for classic lines, balanced trim, and curb appeal, the best window upgrade is the one that looks like it was always meant to be there. We focus on details like sightlines, frame depth, and clean finished edges that respect your home’s character.
- Clean fit that preserves original openings
- Finishing that supports symmetry and proportion

Local insight: Homes with historic trim or distinctive casing benefit most from installation choices that remain balanced, intentional, and architecturally correct.
Full-Frame & Retrofit Installations
Every installation is completed by experienced professionals who understand the craftsmanship and care that Niagara-on-the-Lake homes deserve. Whether it’s a heritage property near Old Town or a modern build in Virgil, our installations are tailored for long-term comfort, performance, and energy efficiency.
Retrofit (Insert) Installation
This method upgrades your home without disturbing existing interior or exterior finishes — ideal for preserving the town’s distinctive heritage character. New windows are installed into your current frames and finished with elegant Cove trim inside and protective aluminum capping outside.
Full-Frame (Brick-to-Brick) Installation
A complete replacement that removes the entire window system and rebuilds it for maximum efficiency, structure, and long-term durability — ideal for older homes or full exterior refreshes.
No matter which method you choose, expect precise workmanship, clean finishing, and results that respect your home’s architecture and comfort.

Every window we install is chosen with comfort, performance, and architectural compatibility in mind. These details help ensure your windows continue to perform and look right for years to come.
