Skylight repairs & leak fixes in Dolgellau: what is involved?
We handle skylight repairs & leak fixes across Gwynedd, including Dolgellau. In short: leak tracing, resealing, actuator repairs and glass replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. In Dolgellau, as anywhere, skylight repairs & leak fixes are the usual choice for leaks, condensation, misted units and failed actuators.
From Dolgellau to Machynlleth, Porthmadog and Aberystwyth, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Planned maintenance visits
- Resealing and re-flashing
- Actuator, motor and control repairs
- Upstand and membrane repairs
- Condensation diagnosis
- Seal and flashing repairs
- Storm and impact damage
What to check first
- Commercial roofs need access and fall protection
- Water tracking can show up far from the source
Planning, building control and Dolgellau
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
