Glass Repair & Replacement

Home glass repair and replacement — including 24/7 emergencies

We repair and replace broken, cracked and foggy glass in homes across Oshawa and the Durham Region — sealed (thermal) units, single-pane windows, patio and door glass. If glass breaks after hours, our 24/7 emergency line gets the opening boarded up and secured the same night.

Sealed (thermal) unit replacement

Most modern windows use sealed double- or triple-pane units. When the seal fails, moisture gets between the panes and the glass fogs up. We replace just the sealed unit — not the whole window frame — which saves money and keeps your existing windows in place.

Foggy windows

Condensation between the panes means the seal has failed and the unit can’t be cleaned. Replacing the sealed unit restores the view and the window’s insulating value.

Single-pane and broken glass

Older windows, storm windows, cabinet doors, picture frames and basement windows often use single-pane glass. We cut replacements to size at the shop and install them, or you can bring the sash in for a quick turnaround.

Emergency board-ups and the 24/7 line

A broken window after a break-in, storm or accident can’t wait until Monday. Call 905-665-3256 any time — we’ll clear the broken glass, board up and secure the opening the same night, then schedule the permanent replacement once the new glass is made.

Turnaround times

Single-pane glass is often cut the same or next business day. Sealed units are custom-built to size and usually take one to two weeks. Tempered and specialty glass can take longer — we’ll give you a firm date when you order.

Board-up and same-night securing, any day of the year.

Replace the unit, not the window

We swap the failed sealed unit and keep your existing frame.

Pricing guidance

Repair cost depends on glass type (single-pane, sealed unit, tempered, laminated), size and access. Replacing a sealed unit costs far less than replacing a full window. Emergency board-ups are priced separately from the permanent glass. Call for a free quote — a photo and rough size help us price it quickly.

Common questions

Can you fix a foggy window without replacing the window?

Yes. We replace the failed sealed unit and reuse your existing frame and sash in most cases.

Yes — our 24/7 line is answered after hours. We secure and board up the opening the same night.

Usually one to two weeks, since each unit is built to your exact size.

Often it does, depending on your policy and deductible. We can provide a detailed quote and invoice for your claim.
