Skylight Glass Replacement in Wellington
Glass and Window Repair Wellington replaces and repairs skylight glazing across the city. Cracked panes, fogged sealed units, leaking flashings and old acrylic domes that have gone brittle and yellow. Overhead glazing is a high consequence position, so replacement glass is laminated, which stays in the frame rather than falling into the room if it ever breaks.

Four quick questions. Most quotes come back the same day.
Skylight leaks in Wellington are usually a flashing problem instead of a glass problem. Wind driven rain arrives at a roof from the side as much as from above, and a flashing detailed for vertical rain lets water past. The other common cause is condensation, which people report as a leak because it drips from the same place. Telling those apart before anyone gets on the roof saves a lot of money.
Leak or condensation
A leak appears during or shortly after rain and follows the weather. Condensation appears on cold clear mornings, often with no rain at all, and it is worst in bathrooms and kitchens where the moisture load is high.
Fixing a flashing will not stop condensation. Upgrading the glazing and improving ventilation will. We work out which one you have before quoting.
Laminated glass overhead
NZS 4223 treats overhead glazing as a position where failure means glass falling on someone. Laminated glass cracks but holds together on its interlayer, so it is the standard choice. Toughened glass on its own is not appropriate overhead.
Old acrylic domes
The acrylic domes fitted through the 1970s and 80s go brittle, yellow and craze under UV, and eventually crack. They can be replaced like for like, but on most homes it is worth moving to a modern glazed unit at the same time, because the dome was single skin and it is a permanent cold spot in the ceiling.
Leak or condensation, and why it matters
Telling them apart from inside
A leak appears during or shortly after rain and follows the weather. Condensation appears on cold clear mornings with no rain at all, and it is worst in bathrooms and kitchens where the moisture load is high.
Getting that wrong is expensive, because one answer involves a roofer and the other involves glazing and a fan.
Old acrylic domes
The domes fitted through the 1970s and 80s go brittle, yellow and craze under UV until they crack. They can be replaced like for like, but they are single skin and act as a permanent cold spot in the ceiling.
Moving to a modern glazed unit at the same time usually costs little more and fixes the condensation the dome was causing.

Skylight Glass Replacement in Wellington: common questions
Why does my skylight drip on cold mornings but not in the rain?
That is condensation, not a leak. The glass is the coldest surface in the room and moist air condenses on it. Better glazing and ventilation fix it.
What glass goes in a skylight?
Laminated safety glass. Overhead glazing has to hold together if it breaks instead of falling into the room.
Can my old plastic dome be replaced with glass?
Usually yes, and it is worth doing. The old domes are single skin and act as a cold spot in the ceiling.
