I am beginning to create a grading system by which to help educate churches as to the severity of the aging and degradation of their SG windows.
Frequently, a church without much funding will ask us which windows are the worst and tackle those first, then comeback later for more; as the funds become available. Each time this happens, it seems as though some arbitrary judgements are concluded and given to the church as to which windows are acceptable and which face imminent failure.
I would like to create a system by which to grade every window in every church that we bid. Even if for nothing more than our records.
Does anyone know if a guide like this has been compiled? Or do each of you captians of industry have your own closely gaurded guide? Or is it just a judgement call each time with every church?
I would appreciate any and all help with this endeavor...

| I'd say it's a judgment call on a window by window basis. For example. A bowed window may or may not be a problem. Many bowed windows got that way early on. The putty is set, and the window is solid with no broken glass. This window should be watched, but needs no immediate work. A similar bowed window may have unvented protection glass, broke glass pieces, deteriorated leads. This situation calls for immediate work. So any "grading" system needs lots of variables. Best to just survey the Church and list the order in which the window "may" need to be worked on and why.

That makes a lot of sense.
I was thinking of it more like; in order for a window to get a failing grade it would have to have a combination of problems that would lead to a possible collapse/failure. And of course, education on whether or not something is "actually" a problem is always up for debate.
But the grades would have criteria that would be directly related to the physical and aesthetic "wholeness" of the window.

Bill, when I work with churches, I try to impress on them THEY are the caretakers...of a leaky roof, broken sidewalk and/or bowing stained glass.
But, the stained glass may have been like that for years, so we look at the windows together, point out any broken pieces, or where there is daylight showing thru, or broken lead joints. then I insist they take a series of photos (8x11) date them, and then mark the photos to indicate the things we had just discussed. And then, periodically they need to recheck their windows against these dated photos to see if there is any broken glass which would indicate some movement. In addition, many people now own a laser level, and I show them how to measure how much the window is bowing, mark that on the photo, and then that is part of the process in 10-12 months - And I tell them to keep the photos off site in their own safe deposit box.

| Dick Millard has posted a guideline for restoration before that he wrote in 1985. It was posted this fall either on this board or the yahoo forum. I have attached it to this e-mail. Attachment: Guide lines for Restoration.doc (Downloaded 22 times)

| I wanted to clarify I was only trying to point out that some information had been posted on the subject of degrees of deterioration of windows by Dick Millard. He has informed me via the Forum that he feels I have misrepresented his information. I am sorry if this has caused confusion.

I woke in the middle of the night to realise I'd titled that document guidelines for restoration by pulling it out of my computer in a common file titled so. The proper title should be Technical #3.
In Canada we have all our health care paid for by our taxes. Since we are in that situation we actually discourage extra visits to hospital and doctors offices we get a lot of information on the " when to call the doctor" vein. I think this is maybe the best you can do with a stained glass assessment system as there are so many variables that are site and window specific.
Here in my part of Canada wood frame buildings are subject to freeze thaw cycles that twist buildings and sills in ways you'd never worry about in a warmer place.

Ben,
I have my own 'grading system' for window deterioration which you can find here:

hello everyone...ayla from Beelines here
ditto to everyone's comments....you just have to take one window at a time. we do have a couple of very general guidelines - we recommend pulling the panel whenever more than 25% of the solder joints are broken, or more than 25% of the support bars are torn away. this may or may not be an arbitrary amount of comprimised structural support, but most of our clients seem to grasp the concept quickly when given a ratio-type term.
hope this helps,
ayla
