If you have new windows, you will get new screens once the scaffolding in your area of the building is removed and the hoist joints in that area are repaired by workers on swing stages.
After the scaffolding is removed and hoist joints are repaired, the new windows in that area will receive screens, safety stops, and an inspection.
Please do not ever lean out of yourself or let a visitor or family member lean out of a window (this is extremely dangerous, for most of you that goes without saying....).
