Rooflight leak repairs in Grangemouth

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 Grangemouth 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.

Is your address covered?

Looking at a property near Grangemouth but not quite in it? We work across FK3, FK2 and FK1 and outwards to Falkirk, Alloa and Bathgate. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Grangemouth.

Included in the work

  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Inside check of stains, frame drainage channels and the reveal
  • Controlled water test where it helps pin down the entry point
  • Leak or condensation — We work out whether the water is coming from outside or forming inside on cold glass.
  • Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.

How a repair visit goes

Expect the visit to be mostly looking and testing. Dust sheets go down below the rooflight. The fitter checks seals and glass from inside, then gets up on the roof by ladder or tower. Minor jobs such as clearing a blocked drainage channel can often be dealt with there and then. Bigger work, like new flashing or a replacement sealed unit, is measured up and priced in writing afterwards.

Do you need permission in Grangemouth?

For Scottish homes: building warrant for new rooflight openings; no warrant for replacing a rooflight complete with its frame, provided it meets the standards, including 1.6 W/m²K; planning permission in conservation areas and listed building consent for listed properties. Outside those, permitted development usually covers house rooflights, but the planning authority has the final word, so we check before you commit.

What to send us

Photos help us price the visit. Send one of the stain or drip inside, one of the rooflight from outside if you can reach a safe viewpoint, and a note of when it leaks: in heavy rain, in wind, or all the time. Add the postcode, FK3 or similar, and how the roof is reached.

Common questions in Grangemouth

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.

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.

Do you charge for a leak investigation in Grangemouth?

Yes. Tracing a leak properly takes time on the roof, a close look at the frame and sometimes a water test, so the visit is charged. We confirm the price before you book, so there are no surprises. If a repair is needed beyond what can be done during the visit, it is quoted separately in writing and you decide whether to go ahead.
