Window Preservation Standards

Older and historic windows can be saved with ordinary maintenance, repairs and energy saving upgrades.

In the Fall of  2010 five window specialists realized the time was right to create national standards for the repair and weatherization of old and historic windows. The Window Preservation Standards Collaborative (WPSC) now includes over one hundred and fifty other window specialists from the United States, Canada, England and India.

    Would like to see how much a Window Preservation Standards Book is?

  2. can you put me in touch with someone with knowledge on metal window restoration. I am a contractor. i have a customer with a historic mansion that has what i call Hopes metal casement windows. someone went to all the trouble to glaze in insulated glass units in them years ago and they are all failing. I was told that the glazing compounnd caused the seals to fail on the insulated glass. My question is do i go back with insulated glass units or do i just use single pane glass and glaze it in. I have restored hundreds or wood double hung windows but never metal. i have searched on line and found some stuff but I’d like some more opinions.

    Can you suggest contractors in the Boston, MA, area that use these standards to refurbish old windows?

    Thank you, Karen Howard

    • Thank you for contacting us.

      The WPSC does not make recommendations. However, as an owner of a window restoration company on Cape Cod, and a member of the wider community of window restorers across the country, I will email some names from Saver America’s Windows, and Preservation Massachusetts from my personal email

        Nancy, could you provide me with that list as well? I’m also located in the Boston area. Thank you.

    We should be developing a strategy for using Section 106 and energy conservation standards to make “Replacement windows” exceptional rather than conventional approaches to ‘Rehab’ projects. Is anyone working on that?

    Do you have a list of window specialists available for property owners to reference?

    Greetings! I’ve just become aware of this organization. I’v e purchased the book and have looked through good share of it. Well done! I’ve been working on old double-hung windows most of my life. I’m looking for more information on a couple of things.

    First, I don’t believe there is a section in the book on sash support, counter-weights, etc. I’m currently working on an 1894 Victorian that has spring coil balances. I’m assuming that these must have been on of the very first iterations of this type of system. I’d like to know more about the history of sash support methods.

    Also, I’m interested in details about the sash steaming box that is mentioned in the book.

    Thanks!

    Hi. A number of weeks ago I attempted to post a message here, but apparently it was never approved(?) so I’m trying again! I’m interested in connecting with people who might be familiar with old spring coil tape balances. They are not mentioned anywhere in the Standards book that I could find. All of the windows in my 125-year-old Victorian here in MN have them, but most are no longer operational. Thanks!
