Railing installation in Thornhill
Thornhill is a community, not a city — it straddles Yonge Street with Vaughan on the west side and Markham on the east. We install aluminum picket and glass railings on both sides, from $85/linear ft installed, with the permit office determined by which side of Yonge you're on.
Railing work in Thornhill
Thornhill's streets are older than most of York Region — established lots from the 60s through 90s with mature trees, larger backyards, and a long-running wave of renovations. That mix produces a particular kind of railing work: rear decks being rebuilt bigger and better than the originals, with glass guards replacing the wood that came down with the old deck.
The housing runs from ranch bungalows and side-splits near the historic Thornhill Village core to substantial customs around Bathurst and New Westminster Drive. Front porches here are mostly low-rise — a few steps — where slim aluminum picket fits the established streetscape without shouting.
The practical quirk is administrative: the same street name can answer to two city halls. West of Yonge is the City of Vaughan; east of Yonge is the City of Markham. It changes nothing about the railing — only who you'd call about a permit.

Permits in Thornhill
Permits in Thornhill depend on your side of Yonge Street: the City of Vaughan's Building Standards serves the west side, the City of Markham's Building Standards the east. In both, like-for-like railing replacement generally doesn't need a permit while new decks and their guards do. Tell us your cross-street and we'll point you at the right office.
