Comfort, Efficiency and Curb Appeal
Windows and doors are one of the few upgrades that pay you back monthly. A drafty single-pane window loses heat all winter and gains it all summer, and the deteriorating seal on a twenty-year-old double-glazed unit does much the same thing more quietly.
We install energy rated windows and doors from established Canadian manufacturers, ordered to the measured opening rather than fitted from stock sizes with packing behind the trim.
The installation matters as much as the unit. Most of the performance you paid for is decided by whether the rough opening was flashed, shimmed, insulated and sealed correctly, which is work you cannot see once the trim is on.


ENERGY EFFICIENCY
Comfort Starts at the Rough Opening
An energy rated window installed into an unsealed opening performs like a cheap one. Air moves around the frame instead of through the glass, and the draft you were trying to fix simply relocates to the trim line.
Every unit we install gets the opening inspected and prepared: sill flashing, correct shimming so the frame is square and operable, low-expansion foam or backer rod and sealant at the perimeter, then interior and exterior finishing. Ontario's freeze-thaw cycle punishes anything less.
"Most clients notice the draft is gone before they notice the heating bill."

CURB APPEAL
The First Thing Anyone Sees
Your entry door and front elevation windows set the impression of the whole house. Swapping tired aluminum frames for vinyl or fibreglass, replacing a hollow entry door with an insulated system, or adding a bay or bow window changes the street view immediately.
We help you settle style, colour, grille pattern and hardware against your home's architecture and the daylight you want in each room. Then we handle the exterior capping and the interior casing so the finished opening looks original rather than retrofitted.
"A new entry door and front windows change the house from the street on day one."

Assessment & Measurement
We inspect the existing units and openings, measure each one, and note which are failing and why.

We match product lines to your priorities: energy rating, operation style, colour and budget.
Custom Ordering
Units are manufactured to your measured openings rather than fitted from the nearest stock size.

Openings are flashed and prepared, units set level and square, then sealed and insulated at the perimeter.
Finishing & Cleanup
Interior casing and exterior capping are completed, old units removed, and every opening checked with you.
The North Point Difference
Why Choose North Point for Windows & Doors
Energy Star Rated Products
We specify Energy Star rated units suited to our climate zone, and explain what the rating actually buys you.
Installation Done to Spec
Flashing, shimming, insulating and sealing are what determine whether a window performs. Our installers do all four on every opening.
Finished Inside and Out
Interior casing and exterior capping are included, so you are not left hiring a second trade to finish the job.
