Call 437-344-8490

Oshawa is Durham Region's largest city, with housing that spans post-war bungalows in established neighbourhoods to brand-new builds in Windfields and Kedron. Many of the older homes still have their original 1970s or 1980s sealed units, which are well past their expected lifespan and showing signs of seal failure: fog, condensation, and reduced insulation.

LuminaSky Glass Services provides targeted repairs for Oshawa homeowners. Rather than tearing out an entire window frame, we replace the failed component, whether it is the insulated glass unit, a broken crank, or a cracked door insert. This approach is faster, less invasive, and far more affordable than full replacement.

What We Fix in Oshawa

Foggy Glass / Sealed Unit Replacement

Sealed units from original 1970s-80s installations are common failures in Oshawa's older homes. We replace the IGU with a new factory-sealed unit. Glass is measured first, custom-made, then installed.

Glass Replacement

Single-pane or double-pane glass replacement for windows, patio doors, and sidelights. We cut to size or order custom panels for any opening.

Window Crank & Operator Repair

Stiff or broken crank handles on casement and awning windows are a routine fix. We source compatible operator hardware and install it on-site. Most window hardware repairs are completed on the same day, on the first visit.

Front Door Glass Inserts

Cracked or dated decorative glass in front doors replaced with a new insert. We carry standard sizes and order custom panels to match your door.

Screen & Storm Doors

New screen door installation, retractable screens, and storm door glass replacement for Oshawa residences.

Skylight Repair

Leaking or hazy skylights repaired without roof removal. We replace the glass unit and reseal the flashing to stop moisture intrusion.

Are the original sealed units in older Oshawa homes worth repairing?

If the frame is still solid, replacing just the glass unit is the smartest move. It restores thermal performance and clarity for a fraction of the cost of a new window.

Is repairing a foggy window worth it in Oshawa?

Almost always. The frame rarely needs replacement. A new sealed unit restores your window's insulation and appearance at a significant saving over a full swap.
