WHAT IT INVOLVES
Know what you’re asking for.
Start with the windows you have and the problem you want to address. The appropriate approach depends on their condition, construction and any restrictions affecting the building. Identify the rooms concerned so the proposed scope covers the right openings.
What to discuss in the scope
- A review of suitable window improvement options.
- An agreed specification and window-by-window scope.
Before the visit
- Note window types, approximate numbers and known faults.
- Mention listed status, leasehold arrangements or previous planning advice.
