Markham is the newest housing I regularly work on, and that catches people off guard.

A large part of Markham went up between 1995 and 2010. Those homes are now fifteen to thirty years old. That is exactly the age where original builder windows start to fail, and most owners are not expecting it because the house does not feel old to them.

Why newer houses still need windows

When a builder puts up two hundred homes, the windows get chosen on price. That is not a scandal, it is just how volume building works. But a unit picked to hit a budget in 2003 is not going to perform in 2026. The seals go, you get fog between the glass, and the hardware starts sticking. The house is fine. The windows were always the cheapest part of it.

Unionville is different

The historic village is a different job entirely. Old buildings, protected streetscape, and real limits on what you can change on the front. If your property is in that area I will check what applies before anything gets ordered, not after you have paid a deposit.

What I usually replace in Markham

Casements on the main floor, the big fixed windows across the front, and the sliding patio door to the back. Front entry doors too. A lot of the builder doors in these subdivisions are steel skins that have been baking in the sun for twenty years and the finish shows it.

Areas I cover in Markham

Unionville, Cornell, Berczy Village, Angus Glen, Milliken, Cachet, Greensborough, Wismer, Markville and Thornhill.

The product matters, but the installation is what really makes the difference long term. On a newer house that means taking the time to do the opening properly instead of assuming it is easy because the home is not old.
