potential repairs

Where a casement window is particularly rotten, it may be necessary to effect some of the following repairs. The extent of repair work required for each window will be identified during the initial survey. However, where access is limited this may not always be possible.

sill or frame replacement

Picture28Any rotten elements of the casement frame will be fully replaced with profile matched hardwood section and treated with wet rot, dry rot and wood preservative. We always avoid splice and fill repairs as these reduce the life of the window and increase the frequency of re-paints. The complete repair will be re-pointed (using either mortar or frame sealant depending on the clients preference) and all timber primed. All repairs are guaranteed for 5 years.

replacement casement sash

Where a casement sash is beyond repair, we will manufacture a replica ensuring the inner mould, section profiles and any glazing bars all match. This repair is guaranteed for 5 years.

replacement glazing

Replacement glazing will meet all current building regulations. It will be fitted using putty unless otherwise specified by the client.

repairs to internal sills, mullions, moulding and architrave

In rare cases of extensive rot it may be necessary to replace or splice various sections of internal sill, mullions, panelling, moulding, architrave, etc.  It is possible for us to exactly match any profile where replacement or partial replacement is necessary.


  1. Hi, we have an old house with metal Crickle windows which are leaking with heavy rain and need some attention. Also keen to enquire about cost and ideas for secondary glazing.

    Thank you

    • Hi Janet,

      this is certainly something we could help with. Please contact the office so we can discuss the options with you in more detail and potentially arrange a free survey.

  2. We want to replace single glazed casement and fixed Windows, as well as existing patio doors, on the rear of our 1920’s house. New double glazing needed as rear is north facing, but want to retain existing frames.
