In Swindon, as everywhere, some leaks are obvious; many aren't. Send photos and we'll tell you what we think has failed.

Signs you need leak investigation and inspection
- Previous repairs haven't stopped the leak
- You're not sure if it's a leak or condensation
- You need a written report for a landlord, insurer or builder
Common causes we find
Hidden water paths
Water can travel along bars, decks and linings before it shows.
Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
About Swindon and the SN1 area
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.
If you're just outside Swindon, we also cover Cirencester (14 miles), Chippenham (16 miles), Witney (20 miles).
What should you expect to pay in Swindon?
Guide price for leak investigation and inspection: £145–£295 ex VAT (£174–£354 inc VAT), per visit. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.

Leak investigation and inspection in Swindon: questions
Do you need to visit to price leak investigation and inspection?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Can you repair a lantern someone else installed in Swindon?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Is the visit cost deducted from the repair?
Ask when you book — we'll confirm in writing how the visit is charged if you go ahead with the repair.
Do you provide a report?
Yes, with photos and findings, which is useful for landlords, insurers and disputes with installers.
