Repair is a meticulous craft that mixes historic preservation with contemporary engineering. By using an expert, property owners can maintain the historical integrity of their home while taking pleasure in the conveniences of modern living.

4. Glazing and Puttying
If the glass is broken or if the client picks to upgrade, the expert will install new panes. Lots of professionals now use “slimline double glazing,” which fits into existing sash profiles while offering contemporary thermal insulation. Conventional linseed oil putty is used to seal the glass, keeping the authentic look.
5. Draught-Proofing Installation
