potential sash window repairs

Where a sash 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 replacement

Picture21The full length of external sill and at least 10cm of the outer face and inner cheek will be matched and replaced. Should the rot extend further up the box frame then up to 75cm additional cheek and outer face will be replaced at no extra charge. All replacement timber will be pressure treated with wet rot, dry rot and wood preservative. The complete repair will be re-pointed (using either mortar or frame sealant depending on the clients preference) and all timber primed. This repair is guaranteed for 5 years.

replacement sash

Where a top or bottom sash is beyond repair, we will manufacture a replica ensuring the inner mould, sash horns, section profiles and 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, paneling, moulding, architrave, etc.  It is possible for us to exactly match any profile where replacement or partial replacement is necessary.
