Leaded Windows – Common questions and answers

A. This is one of the most commonly asked questions, but also one of the most difficult to answer without a detailed picture of the window in question or a site inspection.  For example, if a leaded light panel is bowed either fixed or inside an opening casement, the only permanent resolution to this would be a removal and complete re-lead in the workshop.

If there are only 1 or 2 broken panes and they are on the outside edge of the panel they can usually be repaired on site. Whilst a little unsightly (the lead will ripple as glazing is removed and installed) it can be achieved and sealed again with cement or putty. If there are too many breaks or they are central (in the panel) then it will often require removal and restore in the workshop. Repair on and off site are obviously significantly different in cost so it is always best to send in photos and request for what you would ideally like and get an accurate quotation. Contact  if that is the case.

A. We re-putty any lead came pieces that are repaired or replaced to ensure the integrity of the panel. If any existing putty or cement is aged and brittle we can remove and repair areas with fresh putty, which we usually blacken (with a natural linseed oil putty) to blend in with the lead.

A. It’s certainly possible but it is not recommended unless you are confident and competent glazier. This is mainly due to the materials and expertise required to make a neat repair. For traditional lead window repair, skills required are glass cutting, soldering and putty glazing. If you need to just do a temporary repair before contacting a glazing expert then a clear silicon or a clear resin are normally ok.

A. Usually yes but unfortunately there are no guarantees or golden rules – it depends on where the breakage(s) are and the state of the existing lead which sometimes can be very brittle. If you are unsure the best thing to do is consult a specialist glazier like Craft Glass who can give some initial advice and  options on how to proceed. 

A. Of course. Traditional leaded light specialists usually carry stocks of older glass specifically used in replacement of quarrels or even whole new panels. The cost of authentic or antique glass is however much higher than regular clear or float glass due to pure economics of volume. As a compromise therefore glass is normally graded and expensive grades are used only as a % of a panel (e.g. 1 in 4 or 6 panes).
