use a heat gun, (essentially a hi-temp hair dryer) or --very-- carefully with a propane torch. either one will get the glass hot enough to crack it, so be careful. also, try not to breathe the vapors. be patient, and let the heat source do the work. Be aware, too, there are probably glaziers' points (little metal fasteners) under the putty, that may have to be pried out of the wood. |

Removal of old window putty???
I have the problem with some old double hung sash windows. I tried the heat gun method with some success but still managed to crack a few panes not from excessive heat but from pressure applied scraping the putty out. I found that the glass was not necessarily evenly supported by the rebate on the other side. I've switched to using a multi tool with oscillating saw blades. With a little care this is a little easier and quicker, but patience is the key word whatever the method. use a heat gun, (essentially a hi-temp hair dryer) or --very-- carefully with a propane torch. either one will get the glass hot enough to crack it, so be careful. also, try not to breathe the vapors. be patient, and let the heat source do the work. Be aware, too, there are probably glaziers' points (little metal fasteners) under the putty, that may have to be pried out of the wood. Also, old window caulk can contain asbestos http://www.greenstreamenvironmental....-your-windows/ John T. |

My understanding is that asbestos is relatively safe to work with in a non-friable (not a dust) state. Particulate masks are always a good idea, as the paint may be lead based as well... |

Badly deteriorated putty or caulk is friable - when you start to mess with it. especially using the multi-tool Also - a responsible worker will not only protect himself with properly rated respirator - but do his utmost to prevent the microscopic fibres from dispersing into the room and vents & such.

John T. The real gotcha is that you have to dispose of it as a hazmat, you can't just throw it in the trash. |

Asbestos can be wet so as to minimize dust...I guess I could/should have been more clear (or refrained from any comment at all)...I was basing my comments as a DIYer working within one's own home, not as a business...Whole new level of care to be invoked if a contractor...IMO, best left to pros that specialize in this field...cost can be prohibitive... |

Whole new level of care to be invoked if a contractor...IMO, best left to pros that specialize in this field...cost can be prohibitive... The DIY homeowner needs to be aware of the potential hazards. Then, he can make his-version of an intelligent decision - which, as we all know - will be to ignore all safety precautions completely. Asbestos in the home is don't ask / don't test / don't tell for most homeowners, and, unfortunately many contractors. John T. |
