Skylight replacement in Sandy: what is involved?
Thinking about skylight replacement in Sandy? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Skylight replacement suits yellowed domes, misted glass and leaking roof windows.
Jobs in Sandy are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

- Like-for-like size replacement

Things we check at survey
- Enlarging the opening changes the structure and may need approval
- A replacement is a chance to meet current thermal standards
Planning and building rules for Sandy
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

We remove it from site and recycle what can be recycled.
