Does anyone know if there’s a source for replacement spring balances for double-hung windows? I’m not interested in replacing my windows, just the balances.
The windows are about 50 years old, double-hung, single pane, divided lite, 8 over 8 windows. They’re about 42″ wide and about 52″ tall overall.
Also, do I need to be concerned about different spring strengths to compensate for the weight of the sashes? These windows are larger than the typical double-hung and I’m concened that a one-size-fits-all spring balance may be too weak to compensate for their weight.
I’m located in the Boston area.
My thanks for any assistance or advice you can offer!
