Areas around Sunbury-on-Thames we cover
Sunbury-on-Thames and the districts around it, TW16, TW17 and KT12, all sit inside our working area. So does the ground between Sunbury-on-Thames and Walton-on-Thames (1 mile), and on towards West Molesey (2 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.
On the day, we cover
- Failed sealant cut out, joints cleaned, dried and resealed
- Inside check of stains, frame drainage channels and the reveal
- Outside inspection of glass, frame, sealant, flashing and roof covering
- Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.
- Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.
How a repair visit goes
On arrival we agree access and protect the floor. Then a methodical check: glass for misting or cracks, seals for gaps, the frame for movement, the upstand and roof covering for splits or water lying against the kerb. If the cause is obvious and minor, it can usually be sorted as part of the visit. If not, you have the evidence and a priced repair plan, and the choice is yours.
Regulations for Sunbury-on-Thames properties
Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.
What to send us
Before booking a visit, send what you can: a photo of the ceiling or reveal where water shows, a photo of the rooflight from outside, the roof covering if you know it, and whether it is one rooflight or several. We use that to price the visit and to bring the right materials.
Common questions in Sunbury-on-Thames
Do you charge for a leak investigation in Sunbury-on-Thames?
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.
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.
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.
