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 $75/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.
What we install in Thornhill
Common jobs around Thornhill
Deck rebuild guard packages
Renovated rear decks on mature lots taking framed or frameless glass where the old wood guard used to be.
Low porch and step rails
Slim black aluminum on the shallow front porches typical of Thornhill's older streets.
Balcony guard replacements
Second-storey balconies on 80s and 90s homes where original railings have aged past their anchors.
Pricing for these jobs is in the deck railing cost guide and the aluminum railing cost guide. Job details are on the porch railing, deck railing installation, and railing replacement pages.
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.
