When it is impractical to remove a panel to our workshop for repair we carry out on-site repairs. When we first arrive on-site we photograph any damage to the glass or leads. We can then fully assess what materials are needed and give a guide to estimated time for completion of the repairs. It is not always possible to give an exact quote. When the windows are old, the lead and glass are far more fragile. This can mean that when broken pains are removed the pressure in the panel changes and very old glass can occasionally crack.

We do make every effort to avoid further breaks but it is not always possible due to the unforgiving nature of glass. The lead cames in old panels can occasionally be damaged during removal. This is caused by the different tension in the leads, causing them to twist out of shape, if this happens they will need to be replaced.

The method for on-site repairs are similar to those used in the workshop. The solder is removed in the same way; the leads carefully lifted using an oyster knife. Once the broken pane has been removed the pieces are used to create a pattern to cut replacement glass. If the pane is missing completely several measurements are taken to allow a pattern to be created. The next step is to clean leads of all old cement, replacing any damaged leads. The replacement glass is then fitted and the leads lightly flattened. The lead joints are soldered, the leads cemented and flatten completely. The final stage is to clean off any excess cement and blacken solders and leads.
