🏆 1. WindowBroker – Ottawa’s #1 Window Replacement Comparison Platform
WindowBroker is not a traditional installation company — and that is precisely what makes it unique.
Instead of manufacturing or installing windows directly, WindowBroker acts as an independent comparison platform that connects Ottawa homeowners with pre-vetted local window installation providers based on:
-
Budget
-
Installation requirements
-
Product preferences
-
Energy efficiency goals
-
Financing needs
This approach allows homeowners to compare multiple installation companies without committing to a single brand from the outset.
Unlike traditional window providers who promote only their own products, WindowBroker provides access to multiple installers offering:
-
ENERGY STAR® certified windows
-
Triple-pane glass upgrades
-
CSA-certified installations
-
Vinyl and hybrid frame systems
-
Low-E coated glazing
-
Argon or krypton gas insulation
Homeowners using WindowBroker can request quotes from multiple Ottawa window installers through a single platform, allowing for easier price comparison and installation timelines.
This is particularly beneficial in a market where installation quality and warranty coverage may vary significantly between providers.
