Skylight repairs & leak fixes for Towcester: the essentials
We handle skylight repairs & leak fixes across Northamptonshire, including Towcester. In short: leak tracing, resealing, actuator repairs and glass replacement. 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. Skylight repairs & leak fixes suit leaks, condensation, misted units and failed actuators.
We work across Northamptonshire, including Towcester, and in neighbouring towns such as Northampton and Daventry. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Actuator, motor and control repairs
- Glass unit replacement
- Upstand and membrane repairs
- Resealing and re-flashing
- Condensation diagnosis
- Storm and impact damage
- Misted unit replacement
Before you order: points to check
- Repairs are charged — the free survey applies to new installations
- Parts availability varies with the age of the unit
Planning and building rules for Towcester
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. 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.

Questions about skylight repairs & leak fixes in Towcester
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
Is it condensation or a leak?
Condensation forms on the inside face on cold days and comes back in the same pattern. A leak appears when it rains and often tracks down the reveal.
Do you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
Do I need to be at home for the survey in Towcester?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Towcester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
