Areas around Holyhead we cover
Jobs across LL65, LL64 and LL63 are part of our normal cover for Holyhead. 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 Caernarfon and Bangor 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 we do on the day
- Outside inspection of glass, frame, sealant, flashing and roof covering
- Controlled water test where it helps pin down the entry point
- Inside check of stains, frame drainage channels and the reveal
- Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.
- Age of the rooflight — We weigh the age and condition of the unit before recommending a repair.
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.
Planning and building rules in Wales
Wales sets energy limits of 2.2 W/m²K for rooflights and 1.4 W/m²K for roof windows, and new rooflight openings generally need building regulations approval. Replacement units are controlled fittings; we are not registered with a competent person scheme, so ours are covered by a building notice to the council. Planning permission is needed for rooflights in conservation areas, National Parks, AONBs and World Heritage Sites. We check which applies and include the fee in your quote.
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 Holyhead
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.
Is it condensation or a leak?
Condensation tends to appear on cold mornings, on the inner face of the glass, and runs down the frame. A leak usually follows rain or wind from a particular direction and often stains the ceiling around the opening. Blocked condensation channels can make the two look alike. Photos and a note of when it happens help us narrow it down before the visit.
Will resealing fix my leaking rooflight?
Sometimes. If the sealant has simply aged and the flashing, upstand and glass are sound, a careful reseal on a dry day can solve it. If the real problem is ponding water, a low upstand or a perished membrane, fresh sealant will only hide it for a while. We tell you which one you are dealing with before recommending any work, and quote the proper fix in writing.
