Glass and window subtrades for your projects
Need window contractors in Winnipeg who'll take a subtrade scope? We connect general contractors, renovators and builders with independent local glass and window pros. You send the scope; they quote it, measure on site and work to your schedule.
- Quoted from scope or drawings
- Windows, showers, mirrors and railings
- Measured after framing

Scopes
Scopes we can match: windows, doors, showers, mirrors, railings
Windows and doors
Replacement and new-construction windows, garden doors and sealed units, retrofit or full-frame. See replacement windows.
Showers and mirrors
Framed and frameless shower enclosures, vanity and gym mirrors, and glass cut to size.
Railings
Glass guards for decks, stairs and balconies. See glass railings.
Code and permits
Manitoba code and permit points to know
Manitoba has enforced the 2020 national construction codes since the start of 2024, at energy Tier 1. In Winnipeg, the City lists same-size door and window replacement as work that needs no building permit, though it must still meet code and zoning. New or enlarged openings are different: check with the City, or the municipality outside the city.
Sequencing
Coordinating glass on renovations and new additions
Bring the pro in early
Settle rough openings and the glass spec before framing.
Measure after framing
Windows are measured to the framed opening, shower glass after tile, railings after the deck is finished.
Allow for lead time
Sealed units and tempered glass are made to order. Schedule the wait rather than holding other trades, and keep grinding sparks and mortar off installed glass.

Tax
Tax treatment on installed work
A Manitoba contractor installing or repairing real property pays RST on materials and should not charge RST on their billings for that work, so installed glass quotes normally show GST only. If one shows RST, ask why. We don't give tax advice.
Basement suites
Basement suites and egress windows
Basement suite conversions come up often, and they bring bigger bedroom windows. An egress window has to meet the Manitoba Building Code's size and opening rules, and a new or larger foundation opening isn't a same-size swap, so check with the City before cutting. The glass pro can match the new windows to the rest of the house.
Send a scope
How to send a scope and drawings
Use the quote form and attach drawings, a window schedule or photos, with your timeline. Say whether it's supply and install, and whether openings are framed. We pass it to a pro who does that trade; the contract and warranty are between you and them.
