London questions

Good to know.

What homeowners in London ask before getting started. Something else on your mind? Just ask.

Which parts of London do you cover?
All of them — including Byron, Masonville, Oakridge, Hyde Park and the surrounding Southwestern Ontario. If you're just outside London, we almost certainly still reach you; just ask when you request your quote.
How does the free consultation work in London?
We visit your home, measure every opening and talk through materials, finishes and budget — free, with no obligation. Your itemised quote follows within two business days. We group London consultations and installations into scheduled Southwestern Ontario routes, coordinating dates with you in advance so delivery and installation happen efficiently in one visit wherever possible.
How long will my project take?
Every window and door is manufactured to measure at our own Toronto facility, so lead times stay in our hands rather than an importer's. We confirm the manufacturing timeline in your quote, and installation in London is booked onto our next Southwestern Ontario route once your units are built and inspected.
Can you install windows in London during winter?
Yes — we install year-round across Ontario. Our crews work one opening at a time, so your home is never left open to the cold, and we use foams and sealants rated for cold-weather installation.
