Skylight Repair Without a Full Tear-Out
Skylights bring natural light into your home. When the glass seal fails or the skylight starts to leak, they turn into a problem fast: fog between the panes, water stains on the ceiling, drafts, and higher heating bills.
Most of the time, the skylight frame is still in good shape. Only the glass unit or the seal around it has failed. LuminaSky Glass Services replaces the insulated glass unit inside your existing frame and repairs leaks at the source, so you avoid the cost and mess of a full skylight replacement.
We're a Toronto skylight repair team working on homes and businesses across the GTA. We service all major skylight brands, including Velux, Fakro and ODL, as well as custom skylights.
Skylight Problems We Fix
Skylight leaks
Water stains, drips, or damp drywall around the skylight. We inspect from inside and outside to find the real source: failed sealant, worn flashing, or a failed glass seal. Then we repair that, not just the symptom.
Foggy skylight glass
Condensation or haze between the panes means the seal in the glass unit has failed. It won't clear on its own. We replace the glass unit and keep your frame.
Cracked or broken skylight glass
Hail, falling branches, or impact damage. We replace the glass with a new sealed unit.
Full skylight replacement
When the frame itself is damaged or rotting, we replace the whole skylight, glass and frame. We'll tell you honestly whether a glass replacement, a leak repair, or a full replacement makes sense for your skylight.
Types of Skylights We Service
- Fixed skylights (non-opening)
- Venting skylights that open for fresh air
- Flat roof skylights
- Skylights in vaulted and cathedral ceilings
- Tubular skylights (sun tunnels)
- Dome skylights (supply and install, including building a new curb)
- Velux, Fakro, ODL and custom skylights
Energy-Efficient Replacement Glass
Older skylights often lose a lot of heat in winter. When we replace a skylight glass unit, we offer energy-efficient options: low-E coated glass and argon-filled sealed units. They help keep heat inside in winter, reduce heat gain in summer, and cut down condensation on the inside of the glass.
Signs Your Skylight Needs Repair
Water stains or bubbling paint on the ceiling around the skylight
Fog or moisture trapped between the panes
Drips or condensation running down the skylight well
Cracked or chipped glass
Cold drafts near the skylight in winter
Ice buildup around the skylight on the roof

Skylight Restoration
Skylight Leak Repair Cost
Skylight leak repair cost depends on the cause of the leak and the size and type of the skylight. A sealant repair costs much less than replacing a glass unit, and replacing the glass costs much less than replacing the whole skylight.
The price depends on:
- What's causing the leak or fog (sealant, flashing, or the glass unit)
- The size and type of skylight
- Whether the glass is standard or energy-efficient low-E
- Roof access and the height of the skylight
Send us a photo of your skylight from inside, and we'll give you a free quote, usually the same day. If you prefer an in-person inspection, the visit is $30 and it's credited toward your job.
