We recommend choosing an installer who provides a written scope, itemised quotation, insurance details and evidence of relevant training. Customers can also compare customer reviews and local listings such as GoTradesman, while checking whether the proposed work requires certification through an appropriate competent-person scheme.
A free survey should record window dimensions, roof pitch, access arrangements, internal finishes and signs of damp. We use those details to explain the difference between window repair, window replacement and a larger roofing project, without assuming that the most expensive option is necessary.
After installation, we check opening operation, flashing, seals, insulation and internal trim. We provide maintenance guidance and explain what to monitor after heavy rain. Where other work is planned, including door installation, solar panel installation or wider home improvement, we coordinate sequencing to protect the new roof window.
