Project spotlight · Enclave Court, Kleinburg (Vaughan)

Built to the architect's half-inch.

A custom estate backing onto a ravine, an issued architectural drawing set, and a window schedule most companies would decline to quote. Here's a real Vaughan project from our books, exactly as we built it.

What the homeowner wanted

Walls of glass, spec'd by their architect. A kitchen window ten feet wide under a transom, with the sill landing on the countertop. A four-panel Vista patio door nearly twelve feet wide and over nine and a half feet tall. A trio of curved-top picture windows in the living room. All of it in Iron Ore charcoal outside, white inside, triple-pane glass throughout — with grill patterns matched to the home's existing windows.

What made it hard

  • An issued drawing set. Every unit sized to the half-inch — the patio door measures 140⅞ inches wide — translated from the architect's schedule into manufacturer orders, opening by opening.
  • A structural cut with stone portals. The centre living-room window was a full cut — new lintel and header, with stone portals worked into the facade so the trio reads as original.
  • Curved-top glass. Three eight-foot picture windows with curved heads — the glass and frames follow the arch of the stonework above them.
  • Sheer scale in triple pane. Ten- and twelve-foot units in triple glass are seriously heavy — every one moved up to a raised walkout and set plumb without a scratch on the finished interior.
  • Grills that match the house. A custom colonial grill layout, drawn by hand for the manufacturer, split to mirror the existing windows inside and out.

Good to know

Vaughan window replacement FAQs

Do I need a building permit to change a window opening in Vaughan?

Straight like-for-like replacements don't need a permit in Vaughan. If the structure changes — cutting a new opening, enlarging one, or altering what carries the masonry above — the City of Vaughan requires a building permit and inspection. When a project needs one, we handle the paperwork and build to pass.

Which parts of Vaughan do you serve?

All of Vaughan — Woodbridge, Maple, Kleinburg, Concord, Vellore Village, Sonoma Heights, East Woodbridge, Islington Woods, and Thornhill, plus neighbouring Richmond Hill, King City, and Nobleton. We've completed 35+ projects across the city.

Can you work from an architect's drawings?

Yes — bring the drawing set. The Kleinburg estate featured on this page was built from an issued architectural drawing set: curved-top picture windows, a custom grill pattern matched to the home's existing windows, stone portals on a structural cut, and Iron Ore charcoal frames outside with white inside. We translate the schedule into manufacturer orders and build it window by window.

How big can a replacement window or patio door be?

Bigger than most people expect. The Kleinburg project on this page includes a kitchen window ten feet wide under a transom, with the sill landing at the countertop, and a four-panel Vista patio door nearly twelve feet wide and over nine and a half feet tall including its transom — all in triple-pane glass. Openings can also be enlarged with new lintels and headers when the wall itself is the limit.
