Hi, We have a double-hung window that is falling as soon as you unlock the locks.
My friend spoke with someone at Swsico and they said we need to replace the balance and/or the shoe on the upper sash. Looks like something broke at the top and fell to the bottom. Please see picture below. Are you able to confirm and, if so, let me know what parts I need to order?
Thank you for any assistance.
Betty
