Rooflight leak repairs in Dunoon

Misting between the panes means the seal on the glass unit has gone. No amount of wiping will clear it, but the frame may be perfectly sound. Where the maker's design allows, rooflight leak repairs in Dunoon can mean changing just the sealed unit rather than the whole rooflight. Other faults look similar from below: condensation on the inner face, or a slow leak at a perished seal. A charged diagnostic visit, priced before you book, tells you which one you have.

Areas around Dunoon we cover

Fitters travel to the job, so the address is what counts. In Dunoon that means postcode districts PA23, G84 and PA22, and the same teams can just as easily take on work in Greenock, about 6 miles away, or Helensburgh at roughly 8 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

On the day, we cover

  • Inside check of stains, frame drainage channels and the reveal
  • Failed sealant cut out, joints cleaned, dried and resealed
  • Membrane splits at the upstand cut back and patched
  • Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.
  • Upstand height and condition — We measure the kerb and probe the timber for softness.

How a repair visit goes

Most of the effort on a repair visit goes into finding the cause. We start with your account of when it leaks: heavy rain, wind from one direction, or cold mornings, which points towards condensation. That shapes where we look first. Findings are photographed so you can see them for yourself. You then get a clear explanation and, where needed, a written repair quote, fixed before anything further is booked.

Planning, building warrants and Dunoon

In Scotland a new rooflight needs a building warrant before work starts. A like-for-like replacement including the frame is exempt from a warrant but must meet current standards, so the glazing has to reach 1.6 W/m²K or better. For planning, rooflights on houses outside conservation areas can often go ahead under permitted development, but it is worth confirming with the planning authority.

What to send us

Tell us where the water appears, how long it has been happening and what the weather was doing when it started. A couple of photos from inside and outside, plus the postcode, let us price the visit before you book and plan what the fitter brings.

Common questions in Dunoon

Why is my rooflight leaking?

The usual causes are sealant that has cracked or pulled away, flashing or membrane that has perished at the edges, condensation channels blocked with dirt, water ponding against the kerb, or a seal failing on the glass unit. Sometimes the water is coming in elsewhere and running along to the rooflight. A diagnostic visit finds the real source before anyone starts applying sealant.

Can you replace just the misted glass?

Often, yes. Misting between the panes means the sealed unit has failed, but the frame around it may be perfectly sound. Where the maker's design allows the glass to be changed, we measure the unit and fit a replacement, which costs less than a whole new rooflight. Where it does not, or the frame is also worn out, we explain why replacement is the better option.

Should I repair or replace my old leaking rooflight?

It depends on the age and condition of the unit and what has failed. A single perished seal or a blocked channel is worth repairing. A brittle, discoloured dome, a rotten kerb, or several faults at once usually make replacement the better value. After the diagnostic visit we set out both options with prices, so you can decide with the full picture in front of you.
