FAQ
Do you offer a site survey before installation?
Yes, we provide site surveys for more complex or custom installations to ensure accurate measurements and assess structural conditions. This helps us deliver a perfect fit and smooth installation process.
What information do you need to provide a quote?
To provide an accurate quote, we typically need the approximate dimensions, roof type (flat or pitched), preferred glass specification, and project location. Photos or drawings are helpful too.
What are the lead times for manufacturing and delivery?
Lead times vary depending on the complexity of the rooflight, but standard units typically have a lead time of 3–4 weeks. Custom or oversized units may take slightly longer.
Can you help with planning or structural requirements?
While we don’t manage formal planning applications, our technical team can provide detailed information on glass load, unit weight, and recommended fixing methods. This helps architects, builders, and engineers specify the correct structural support for our rooflights.
