Skylight Repair Starts With Finding the Real Problem
A drip under a skylight can come from at least five different places: the head flashing, the side step flashing, an ice dam above the unit, a failed glass seal or plain condensation from warm house air hitting cold glass. Each one has a different fix. Guess wrong and you pay twice.
That is why every repair starts with a diagnosis. We test from the bottom of the skylight up with a hose so we know exactly where water gets in, use infrared thermal imaging to find wet insulation and cold spots, and check the shaft for missing insulation or vapour barrier. Then you get the cause in writing, with a CAD price to fix it.
The 4 Skylight Repair Services We Offer

- Skylight flashing repair with factory kits or hand-formed step flashing, $400 to $1,200.
- Emergency skylight service 24/7 for storm leaks and broken glass, from $650.
Residential Skylight Repair
Kitchen Skylight Leaks
Steam and heat make condensation worse here. Often the fix is shaft insulation, not new flashing.
Bathroom Skylight Drips
Shower humidity condensing on cold glass is the number one bathroom “leak.” Venting units and vapour barriers fix it.
Bedroom and Hallway Stains
Usually head flashing or ice dams. Testing confirms which.
Attic and Loft Skylights
Deep shafts with no insulation drip in January. Roxul batt and poly fix it.
Fogged Glass Anywhere
A failed seal. Pane replacement from $450 if the frame is good.
Post-Reroof Leaks
New roofs sometimes reuse old skylight flashing. We re-flash with a proper kit.

Our Repair Expertise
After 20 years we can usually guess the cause from the stain location and the weather. But we test anyway, because guessing is how homeowners end up with three repairs on the same skylight. Nine times out of ten, the leak we are called to is on a skylight someone else already caulked.
What Actually Stops Homeowners From Calling for Repair
“It’s only a small drip.”
In our opinion, small drips are the cheapest ones to fix. Wait, and it is insulation, drywall and framing.
“They’ll just tell me to replace it.”
We tell people to repair all the time. If repair is enough, that is what we quote.
“Repairs never last.”
Caulk never lasts. Proper flashing and real diagnosis do.
“I don’t know who to call.”
Us. Velux and Fakro certified, in-house crews.

Skylight Repair vs Replacement vs Installation: Which Service You Need
Unit sound, one problem: repair. Old, fogged and leaking: replacement. No skylight yet: installation.
Fixed, Venting or Solar: Choosing Your Skylight Type
If a repair turns into a replacement, it is the right time to choose between fixed, venting and solar. Venting and solar units also solve many condensation problems by letting humid air out.
