How we approach skylight replacement in Oundle
We handle skylight replacement across Northamptonshire, including Oundle. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
Oundle is around 38 km from Northampton, and we survey and fit throughout that part of Northamptonshire, including the PE8 district.

What to check first

Planning and building rules for Oundle
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight replacement in Oundle: questions
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
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.
Can you work alongside my builder in Oundle?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Oundle?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
