Traditional Leaded Lights


Leaded Window common questions and answers…

Q. Can you make new leaded lights with old or antique glass?

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).

Q. Can you repair a broken pane in a leaded light panel?

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 Tec Glass who can give some initial advise and hopefully give you some options.

Q. Can I fix a damaged leaded light panel myself?

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

Q. Will a repaired leaded panel be watertight?

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 (a natural linseed oil putty) to blend in with the lead.

Q. How much does it cost to repair a leaded window?

A. One of the most often asked questions but unfortunately often difficult to answer without a detailed picture or site inspection. If (for example) a leaded light panel is bowed whether it be 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.
