Open Sash repairs and retrofits modern windows too.

Posted May 29th, 2017 by Chris Pratt

There are many houses built in the 70’s and 80’s that have casement windows with insulated glass.  Many of the Andersen, Pella and Marvin windows have  serios wear on the exterior,  broken cranks and keepers , worn seals  and  fogged  insulated glass.   If the  wooden sash and the frames are good,  then Open Sash can retrofit them very cost effectively.

Removing the old window and replacing it with an entirely new unit is expensive for three reasons.  1) The unit itself is expensive,  2) It takes a lot of time and money to remove it and dispose of it, and 3)  It takes a lot of time to install the new unit because it involves fitting into the existing exterior and interior trim.   The entire cost /window could be between $1,000-$3,000.00.

An open sash retrofit can be done for  $250–$500, depending on size and how many elements of  the window need to be replaced.  The addition of a frame to the exterior and a low-energy panel gives new life to the outside and adds another layer of glass for triple pane insulation.

Here is an example of house we did in East Montpelier, VT that made the window look new and will  give them another 15-20 years of life, which about what you can expect from a new window.

Just back from Boston’s Savin Hill!

Posted May 22nd, 2014 by Chris Pratt

Spent a week in close quarters with the crew, surviving solely on bar-room Chinese food – all for the sake of completing seven third-floor window retrofits on a lovely 1870s Queen Anne home in the Savin Hill neighborhood of Dorchester, MA.  Curved top windows presented a fun challenge.  The clients were delighted to have the modern factory-made square storms removed to reveal the original elegant design of these classic windows.  Good time all around, and a successful restoration story!

Open Sash is featured in VT weekly, Seven Days

Posted December 15th, 2011 by Chris Pratt

Amy Lilly has written a very good article on Open Sash and window retrofits. She did a really good job navigating a complex subject and  including the perspectives of the homeowner, Caroline Ablels, and the historic preservationist.

She did not interview the folks who manufacture replacement windows – they are the ones I am really competing against.

Seven Days has a huge distribution in Vermont and is known for its quality journalism nationally.

Open Sash restores windows damaged by Irene.

Posted December 8th, 2011 by Chris Pratt

Moretown Realty Office is in the center of Moretown and was at the center of flood damage from Irene.  Open Sash worked to weatherize and add glass to all 24 of the mix and match windows there.

We were able to add glass to old windows that don’t have weights and parting beads, and repaired some badly rotted windows.  We were able to do all the windows in two weeks at an affordable price.

Unidentified Hardware at 20 Vine Street

Posted December 6th, 2011 by Chris Pratt

The variety of styles, mechanisms and alterations found in old windows continues to surprise me.  Usually I can identify what they are, but this one has me stumped.

These are inset in the jambs and used to hold the upper and lower sash in place.  Bwhat is it called. when did they make them, and how did they work?  The house it came from was built in 1907.

Front and back of sash locks? If you know, email me.

What is this called?
