How we approach skylight replacement in Dumbarton
For Dumbarton homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. Typical uses for skylight replacement include yellowed domes, misted glass and leaking roof windows.
We work across Glasgow and Dunbartonshire, including Dumbarton, and in neighbouring towns such as Erskine and Clydebank. Access, parking and how the glass reaches the roof are all checked at the survey.

Before you order: points to check
- Enlarging the opening changes the structure and may need approval
- Upstand and roof condition decide the scope
Consents for skylight replacement in Dumbarton
Scottish householder permitted development (Class 2B, other external alterations) can cover a rooflight that projects no more than 1 metre from the roof, but the right does not apply in conservation areas. Listed buildings need listed building consent where the work affects their character.
Scottish energy standards for glazing, including rooflights, use an area-weighted average of 1.4–1.6 W/m²K in extensions, so most modern units comply comfortably. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.

Skylight replacement in Dumbarton: questions
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Is the survey in Dumbarton free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Dumbarton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
