Single glazed windows and existing external elements
Buildings in a conservation area have caused problems for builders for a number of years when achieving satisfactory performance. If the conservation officer feels that upgrading certain elements for the purpose of Building Regulations have an impact on the historic status then they will allow them not to be carried out.
What is required for our warranty purposes?
If existing windows are being retained in a property and covered by the listing then a copy of the listed building consent will be required providing confirmation of this. A RICS surveyor or window repair/renovation specialist will also need to give a full condition report stating that the existing windows have the capability to form a waterproof barrier for 15 years. A full repair schedule should also be provided if there is any work being carried out on them.
How does it work with external walls and roofs?
Similar to windows, a listed building consent is required confirming that the existing walls/roofs need to remain. They will also require a full condition report by either a RICS surveyor or industry specialist that confirms the walls/roof are structurally sound for 60 years or 15 years if just performing as the waterproof barrier.
