Need Your Old Windows Replaced?
Window Replacement Lethbridge. Save Energy & Money with New Windows
Let's Replace Your Windows The Right Way!
Living in Lethbridge, we know that the high winds can play havoc on our homes. Not just the roofing system, or siding, but also on our windows. If your windows are older or were improperly installed, it’s likely you often deal with a cold draft making its way into your home.
Drafty, old windows are one of the biggest causes of heat loss for a home. It’s also costly for you as the owner because it takes more power and heat to keep your home warm in cooler months.
If you want to increase the energy efficiency in your home, or you have been thinking of upgrading to new vinyl windows, give us a call today.


Replacing Your Old Windows
At South Peak, we do more than roofing. We also offer complete exterior renovations like window replacement in Lethbridge. Often our customers will ask us to replace their old windows while we’re already there to work on the roof or siding. By having us do everything at once, it cuts down on the amount of time your family has to deal with the disruption.
We offer new construction window installation and window replacement to the Lethbridge area. At South Peak, we employ experienced and professional installers.
