Quick Fix / Temporary Stabilization

Sometimes the best durable work cannot be done because there is not enough time, or money. Maybe all the best window specialists are booked out months in advance.

Re: 1950s & 1960s Windows

The welded-glass IGUs (Insulated Glass Unit) are no longer made. The sash with the broken IGU should be removable. A good approach would be to remove the sash and take it to glass shop that knows how to disassemble the sash, have a new IGU made and reassemble the sash with the new IGU. You might fin...

Scratching glass when scraping out putty

To avoid scratching the glass during putty removal: ==> Clean any grit off of the glass before putting the sash in the steam box, or before any scraping. Dust off the glass with a soft-bristle brush, mist the glass with a water-detergent solution and wipe with a soft rag. ==> Just before scraping us...

Priming Putty, Wrinkling

Putty, to prime or not to prime--that is the question. (with a long response) Some window specialists are reporting wrinkling of the surface of the putty after glazing and painting. The Forest Products Laboratory (FPL) has done conclusive wood window tests and demonstrations since the 1950s that pro...

Re: Poor Boy Steam Box Deglazing

"The DaVinci?" Perhaps, but credit is due to my window preservation colleagues for coming up with the idea of steaming window sash and its early development: Marc Bagala, Dave Bowers and Ginger. The Poor Boy Steam Box is just one more step in its development.
