Replacement Skylights Melbourne

Is Your Old Skylight Causing More Problems Than It's Solving?

Leaking. Draughty. Foggy. Impossible to operate. Old skylights go wrong in a lot of ways - and the cost of ignoring the problem only grows. The good news? Replacing it with a new Velux skylight is simpler than most people expect.

Signs It’s Time to Replace

An old or failing skylight isn't just an inconvenience - it's a slow-moving problem that can cause real damage to your home over time. Water ingress leads to ceiling staining, mould and structural issues. Draughts drive up your heating and cooling bills. And a skylight that doesn't open or close properly is a hazard you can't ignore.



The sooner you replace a failing skylight, the less remedial work you'll need to do on the surrounding ceiling, roof and internal plasterwork. Our team carries out Velux skylight replacement across Melbourne, and we can often complete the whole job within a week.

Common Problems We Fix

Leaking Skylight

Water finding its way in around the frame or through the seal is the most common (most urgent) issue. Our leaking skylight repair Melbourne service starts with identifying whether repair or full replacement is the right call.

Draughts & Air Gaps

As skylights age, the seals deteriorate and gaps form around the frame. The result is cold draughts in winter and heat loss that makes your home harder and more expensive to keep comfortable.

Foggy or Condensation-filled Glass

When the seal between the glazing panels breaks down, condensation gets trapped inside and creates a permanent foggy appearance. This can't be cleaned away - the glazing unit needs replacement.

Won’t Open or Close

A stuck skylight - whether it won't open, won't close, or is stuck in a position that can't be secured - is a safety and weather risk. We can assess whether the mechanism needs servicing or the whole unit needs replacing.

Yellowing or Cracked Dome

Older polycarbonate skylight domes yellow, crack, and become brittle over time. If yours looks discoloured or damaged, it's almost certainly past its useful life and replacement will make an immediate difference.

Old, Outdated Skylight

Even if your old skylight isn't actively causing problems, replacing it with a modern Velux model will bring significant improvements in light output, thermal performance, and - if you choose a solar model - smart functionality.
