Markham questions
Good to know.
What homeowners in Markham ask before getting started. Something else on your mind? Just ask.
Which parts of Markham do you cover?
All of them — including Unionville, Cornell, Berczy Village, Cathedraltown and the surrounding York Region. If you're just outside Markham, we almost certainly still reach you; just ask when you request your quote.
How does the free consultation work in Markham?
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. Our crews install across York Region regularly, so Markham visits fold into routes we already run — scheduling is straightforward year-round.
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 is booked as soon as your units are built and inspected.
Can you install windows in Markham 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.
