Skylight replacement for Sandown: the essentials
For Sandown 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for skylight replacement include yellowed domes, misted glass and leaking roof windows.
Jobs in Sandown 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.
Options we can specify in Sandown
- Dome to flat glass upgrade
- Misted glass unit replacement only
- Like-for-like size replacement
- Roof window replacement in pitched roofs
- Upstand rebuild and insulation
- Usually done in a day
- Better thermal performance
Before you order: points to check
- Old glass and domes are disposed of responsibly
- Enlarging the opening changes the structure and may need approval
Planning, building control and Sandown
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Skylight replacement in Sandown: questions
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.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
