Velux roof window installation and replacement in Calne covers new loft conversion glazing, replacement of failed windows, and flashing repairs. Loft conversions on Calne's 1980s–90s estates and Victorian town centre properties are a regular driver of Velux installation demand. The most common call, however, is a leaking Velux where the window itself is fine but the flashing kit has failed — a significantly cheaper fix than full window replacement.
We handle the complete roofing element — tile cutting, counter battening, and the Velux proprietary flashing kit correctly installed. Correct flashing is what separates a long-term weatherproof result from a future leak. Rear-slope installations usually fall under permitted development. Front-slope windows may need consent. We work alongside builders and loft conversion contractors and can coordinate the roofing element within a larger project programme.
"Two Velux windows fitted into loft conversion. Roofing done in a morning, completely watertight six months on."
"Velux leaking for two years — previous roofer said it needed replacing. These identified the flashing as the problem, replaced the kit, dry now. Saved a lot of money."
"Flat roof light on kitchen extension fitted at the same time as flat roof replacement. Kitchen transformed. Good combined value."

Most leaking Velux windows don't need replacing. The flashing kit has usually failed while the window is sound. Flashing replacement costs £150–£350 versus £400–£700 for a new window. We diagnose correctly before quoting.

Velux recommends a minimum glazed area of 10% of the floor area. For a typical loft bedroom of 12–15m², two standard pivot windows (78×98cm) usually meet this. We advise on sizing during the survey.
Internal condensation indicates insufficient ventilation. Solutions include trickle ventilators, upgraded mechanical ventilation, or a triple-glazed thermally-broken Velux. External condensation is normal and not a fault.
