Areas around Clevedon we cover
Jobs across BS21, BS49 and BS48 are part of our normal cover for Clevedon. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Nailsea and Portishead are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
What the job includes
- Controlled water test where it helps pin down the entry point
- Failed sealant cut out, joints cleaned, dried and resealed
- Lifted flashing or tape removed and renewed
- Age of the rooflight — We weigh the age and condition of the unit before recommending a repair.
- Upstand height and condition — We measure the kerb and probe the timber for softness.
How a repair visit goes
A repair visit starts outside. The fitter looks at the roof around the unit for ponding, split membrane, loose flashing and failed sealant, then moves inside to check stains, the frame and the condensation channels. Where it helps, a controlled water test narrows down the entry point. Before leaving, they explain what they found and whether a small fix can be done within the agreed visit, or needs a separate written quote.
Do you need permission in Clevedon?
Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.
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 Clevedon
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.
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.
