Not to bring up a post thats from 5 months ago,I just thought I`d give some info on these..All of the parts are still available in peices for any window sashes and patio doors..you can get complete sahes if you need,the wood runs around 50.00 and these are one of the easiest windows to work on..If yours are clad,that can be slipped on/off very easy..

Scherer Bros. did have a sash replacement program for windows manufactured with window parts supplied by Brightwood corporation. Information on this program and service on your Scherer Bros. windows can be found at www.farnorthwindows.com

UPDATE - MARCH 2015

I wanted to update this thread because it is the first thing that comes up on a Google search.

My home was built in 1996 with Scherer Bros windows. I have to say they are still in pretty good shape considering they are wood and are 19 years old. I had some rotting sashes in the kitchen but otherwise, I had done some maintenance over the years but not a whole lot.

I really didn't know what to do with my kitchen windows so I was searching on the net and found this thread. I went to the Scherer Bros website and found this page.

So I called Scherer Bros and within 2 weeks I had my kitchen windows rebuilt and my patio door serviced and repaired. Amazing service. It's not free but I found the cost to be very reasonable considering the alternatives. The technician Nick was the ultimate professional. He knew exactly what was required and how to do it. The whole process took about 2 hours. The two windows look brand new.

The windows here were what attracted me to this house 19 years ago, and the windows are a big part of what sold this house a couple weeks ago. I think they still look great, and with the ability to rebuild the ones that need attention for a reasonable price, they will last a lot longer now.

This is Nick, Scherer Bros no longer has the patio door wood components and have been referring the repairs to me since I retired and ventured out on my own, let me know if I can be of service.

Nick--Are you still doing Scherer Bros window repairs for double hung?

Another update. We built our home in 1999, using Scherer Bros double pane crank outs.

A few have degraded over the past 22 years. We had their window repair guys come out and repair a total of 6 windows (both sides of two, one window each on another two, for a total cost of about $2400, which included replacing a pane on a basement window that a rock kicked up by a lawnmower broke.

Excellent job. We plan to restain and seal ourselves, but they have a few painting contractors they recommend if you don’t want that chore.

Are you still satisfied with the work that you had done on your 6 windows?

We sold our house last winter; nut they worked well from tge time they were repaired.
