Custom window installation in Hamilton with proper flashing, insulation, and interior air sealing — because a beautiful window installed leaky is worse than the one you replaced.
Window Replacement Hamilton
Replacing windows is one of the most impactful upgrades you can do for energy efficiency, comfort, and curb appeal — and one of the most often botched by chase-the-lowest-price installers. Our window installation service in Hamilton uses proper self-adhering flashing tape, low-expansion window foam, and interior air sealing so the finished install stays weathertight for the full life of the window.
Choosing Windows That Fit Our Climate
In Hamilton's climate you want at minimum a double-pane, argon-filled, low-E window with a warm-edge spacer. Triple-pane is worth the upgrade for north-facing walls, noise-sensitive rooms, or Passive House-adjacent builds. Vinyl frames are the value pick and perform well; fibreglass frames cost more and outlast vinyl by decades. We work with several Canadian manufacturers and size every quote to the performance you actually need.
Full-Frame vs Retrofit Installation
Retrofit (insert) installs are faster and cheaper — the new window goes into the existing frame. Full-frame replacement takes the old frame out entirely, exposes the rough opening, and lets us re-flash and re-insulate everything. Full-frame costs more but is the right call when the old frames are rotting, drafty, or under-sized. We'll walk you through the trade-off on a per-opening basis.
Interior and Exterior Finishing
The install isn't done when the window is in — it's done when the trim is finished. We install exterior brick-mould and matching caulk lines on the outside, and stool, apron, jamb extensions, and casing on the inside so every window looks intentional, not patched-in.
