How To Repair A Crack In The Leaded Glass Design In My Front Door

Rare in today'south new construction, built-in art glass was a regular feature of bungalow-era homes. Leaded doors in a colonnade chiffonier or a built-in buffet, colored glass sidelights in a window, unusual glass in the front-door sidelights, drinking glass textures and hues in a transom—all of these are relatively mutual for the period. Alas, sunlight, pollutants (indoors and out), weather, and gravity all take their toll. Windows and glass panels show signs of age after threescore or 80 years. The leading weakens, cracks appear, and the whole structure may sag and bulge.

Consider the age of the window. If you live in a particularly older habitation, there'southward a chance your stained drinking glass window is over 100-years-old. Once a window gets to be over 100, it'due south probably fourth dimension for some much needed attention to make clean and/or restore it. In response to recent reader questions, we asked a few experts for their recommendations on assessment and repair of old leaded windows.

What are the most common problems homeowners encounter in their stained- and leaded-drinking glass windows?
"Deterioration of lead" is what our experts say is the most common problem for older windows. The glass in windows is joined together with strips of lead soldered at the joints, and the window then is grouted with putty to glaze and seal it. Over time, the putty dries and falls out and the pb so has room to stretch, and weaken. Left unchecked, the window starts to sag and buckle every bit support deteriorates. Some windows also have metal support bars that may corrode or detach from the window, further weakening the glass. Keep in mind, too, the wood frame effectually the window. If it rots or separates, the window will become loose and unsupported.

One easy style to gauge the window's integrity, say Lyn Hovey, is merely to tap on information technology with your fingers. If it moves or rattles, the lead and putty are compromised. If you can get close plenty to examine the atomic number 82 lines and solder joints with a magnifying drinking glass, any cracks will be readily apparent.

What defects can be left lone, commonly?
Cracks are mutual in windows, especially in the lower third, due to the weight of the glass above. If the crack is small-scale or in a department of the perimeter, the structural integrity of the window is commonly not compromised, and the crack can be left alone. Glass artist Brian McNally suggests articulate, UV epoxy to stabilize a cleft and prevent it from spreading (make certain to clean the glass thoroughly beforehand). Sometimes a small-scale piece of pb—chosen a "Dutchman," as in wood repairs—can exist soldered over the fissure without removing the window.

When should you lot repair, and when is it fourth dimension to supplant?
If you accept painted drinking glass or work by a pregnant artist, or yours is a museum-quality house, you'll become the extra mile for restoration. But much former colored and leaded glass was production work.

Expect at the pb lines and the putty that holds them in identify, advises Jo Kobler of White Iris Glass. If the lead is peeling, has become soft and tin can no longer hold solder or is missing in spots, or if there are open up spaces betwixt the lead and the glass, the window should be repaired as soon every bit possible. Pleating (when the glass panes begin to fold over on peak of each other like an accordion) is serious and also requires immediate intervention.

The window should be removed and laid flat for whatsoever repair work to be performed. While lead and putty can exist rebuilt, it'due south always a gamble to detect an exact match to replace old glass. Neumann Studios makes exquisite, hand-painted, kiln-fired glass that tin can exactly match whatsoever manner...merely if in that location are a large number of broken panes and significant deterioration, replacement of the entire window may be the better option, economically and aesthetically.

So, how practise you begin an assessment?
Take clear photos of the window, within and out, is the advice from Century Studios. Study them and ship them to a restorer. If the window is difficult to remove (to be shipped), most restorers will want to come view it on site. Be sure to go references and recall that the lowest bid is non always the most qualified; don't be agape to ask to see examples of their work. Competent drinking glass artisans are at work around the country.

John Hamm of Hamm Glass Studios, Whittier, Calif., undertook the rebuilding of six ceiling-calorie-free panels from Greene and Greene'southward Thorsen Business firm. Cracked pieces are exposed when the panel is taken apart. (The crack was glued with HXTAL epoxy.) "If this panel had been built properly in 1910," says John, "the caste of sagging 100 years later would take been minimal."
