How to proceed

Please follow the steps on the guide given on this web page. If you have any questions at any point in the process please get in touch.


Our current estimated timescale on new work for standard window and door installations is around 15 weeks from full survey to completion, but could be longer or shorter depending on manufacturers and demand.  For larger jobs e.g. conservatory roof installations it would normally be 20-25 weeks from survey depending on project size.
