Old windows with weights and cords
Open a lower window of ones that does not stay up. Remove the screw 3-4" up from the sill on the jambs where the window slides. This is the weight access door. Only one screw, centered, holding the door in, the top is kept in place by a bent bracket attached to the door. Change to heavier weight (from a real hardware store) or make sure the window cord is the correct length when open (the weight should not be bottomed out, resting on the sill or framing).
Be safe, Gary
Clothes taking longer to dry?
Clean the dryer screen in HOT water if using fabric softener sheets.
They leave a residue that impedes air-flow, costing you money.
