Can a glass panel in a door be replaced without a new door?

Yes, in most doors. Inserts, sidelights and transoms sit in frames or stops that come apart, so the glass is changed while the door stays hung. A new door only makes sense if the slab itself is damaged, warped or no longer seals.

Is it expensive to replace glass in a front door?

It depends on the piece. A plain clear insert is a smaller job than a large decorative or laminated one, and a stock size costs less than a custom shape. It's usually well below the cost of a new door. A photo and rough size let a pro quote first.

Does the glass in a sidelight need to be safety glass?

Often, yes. Ontario's Building Code calls for safety glass in sidelights wide enough to be mistaken for a door. If in doubt, tempered or laminated is the safe order, and the pro confirms what the current code asks for your sidelight.

Can just the glass in a transom be replaced?

Usually. A transom is often a single pane or sealed unit held by stops, and it comes out without disturbing the door. Decorative or leaded transoms take more care, and on an older house the original glass may be worth repairing.

The glass in my front door just broke. What should happen first?

Keep people and pets away, then take photos for insurance. Cover the opening from outside with plywood or heavy plastic so the house is secure and dry, and send the photos for a glass quote.

Can I change the entry-door glass on a house in a heritage district?

Check first. In Old Port Credit Village and Meadowvale Village, the district plans cover doors and glazing on the front of the house. Repairs and like-for-like work usually take a lighter path than a change of style. The heritage village guide explains both approvals.

Replacing the glass in a door, sidelight or transom

The glass in a front door sits in a frame of its own. In most doors that frame opens, and the glass is changed while the door stays hung. Most sidelights and transoms work the same way. If the door is solid and closes well, changing only the glass is usually the simpler job. In a condo townhouse, ask management before changing how the front door looks. We connect you with an independent local glass pro who replaces door glass and can say what's possible for your door.

Each piece of glass here can be replaced on its own.

Fog, cracks, privacy

Privacy, decorative and fogged insert glass

Fog inside an insert or sidelight

Haze between the layers means the seal has failed, as in a foggy window. It won't wipe off. The glass unit is replaced; the door and its frame stay.

A crack or a break

Keep people clear, photograph it for insurance, and cover it from outside. The broken glass steps cover the first hour.

Too clear, or dated

Frosted, textured or decorative glass adds privacy to a front hall. Send a photo of the door and the frame size so the pro can suggest options that fit.

What can be swapped

Inserts, sidelights and transoms: what can be swapped

Storm door panes have their own page, storm doors. For the rest of the entry:

Door inserts

Most steel and fibreglass doors hold the glass in a two-part frame screwed together through the door. The frame comes apart and a new insert of the same size goes in.

Sidelights

The tall glass beside the door is usually a sealed unit or an insert in its own frame, replaced without touching the door.

Transoms

The glass above the door is often a single pane or sealed unit held by stops. Older decorative transoms set in wood need more care.

Safety glass

Safety glass: when tempered or laminated is required

Ontario's Building Code calls for safety glass, tempered or laminated, in storm doors, sliding doors and sidelights that could be mistaken for a door. Large glass that reaches low on an entrance door is covered too. The pro orders to the rule for your piece and checks it against the current code.

Tempered

Heat-treated to break into small, blunt pieces. It can't be cut afterwards, so it's made to the exact size.

Laminated

Two sheets bonded to a clear plastic layer. It cracks but stays in the frame, which makes a break-in slower.

Heritage entrances

Heritage entrances in Port Credit and Meadowvale Village

The Old Port Credit Village plan asks owners to conserve doors, glazing and door surrounds on the front of the house. The Meadowvale Village plan asks for original doors to be kept, and door work that follows it needs a Clearance to Alter. Both lean toward keeping what's there, so ask about repairing an original door first. Check with City heritage staff, and see our heritage village guide.

What affects the quote

Pricing door glass: what the quote follows

Door glass is made to size, so the quote follows the piece:

Size and shape of the insert, sidelight or transom
Clear, frosted, textured or decorative glass
Tempered or laminated, single pane or sealed unit
How it's held: an insert frame, stops, or glass set in wood
Whether a matching decorative pattern is still made

Photograph the door from outside and inside, with a tape measure across the glass.
