Find the source of the skylight problem

  • Water stains or dripping around the skylight, especially during or after rain.
  • Moisture on the room-side surface, or persistent fogging trapped between the panes.
  • Cracked glazing, deteriorated seals or visible frame damage at the skylight opening.

What we check and repair

  • Review of where and when moisture appears, with glazing and room-side condensation considered separately.
  • Assessment of visible seals, frame condition and the curb or roof interface where safely accessible.
  • Confirmation of compatible glazing, access needs and the repair scope before work is approved.

When glass-only or localized repair may work

Glass-only or localized repair is considered when the frame and glazing system remain serviceable, the failed component is identified and safe access can be arranged.

When replacement or roof-interface work is needed

A new skylight or separate roof-interface work may be needed when the existing frame, curb or surrounding assembly cannot support a reliable localized repair. We confirm the scope before quoting.

Questions about Skylight Repair, Replacement & Installation

My skylight is leaking - is it the glass or the flashing?

Water may enter at the curb, flashing or surrounding roof, while fogging between panes can point to a failed sealed glass unit. We review the location and timing of the moisture, then confirm what can be inspected safely and whether separate roofing work is needed.

Can you replace foggy skylight glass without replacing the whole skylight?

Sometimes. The frame, glazing system and curb must be suitable for glass-only replacement, and a compatible unit must be available. We identify the system and access requirements before confirming whether the existing skylight can be retained.

How is skylight repair priced?

The quote depends on the skylight size and system, the failed component, access and any separate roof-interface work. We explain what is included and agree the scope before starting; custom glazing may require measurement and fabrication.

Can dripping inside a skylight be condensation rather than a leak?

Yes. Room-side condensation, moisture between panes and rainwater entering around the opening need different assessments. Tell us where the moisture appears and whether it follows rain or cold weather. We do not assume that new glass or extra sealant will solve every case.

I hired DoorWin services to replace two cracked glass windows for a unit at my triplex. An exterior porch window and interior stairwell window I just needed the panes of glass replaced and not the entire frame . DoorWin was happy to do the job. Unlike some other companies who wanted to replace the entire frame at a higher cost. They were very quick with a quote and were able to perform the job on an extremely tight timeline that I had to unexpectedly move up. Very professional. Friendly. Dependable. Competitive prices. Took away all materials and left a clean worksite. Would highly recommend and will work with them again if I need another window repair.
