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
Any 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.
