Exterior Doors
The exposed side of exterior doors needs to be painted or properly stained and varnished to prevent discoloring and delamination. Weather stripping is a must to prevent drafts.

Thresholds: Keep all adjustable thresholds adjusted & sealed as necessary.
(Over adjusting will cause premature wear of the weather stripping)
One can check the drag on the adjustments by using a piece of paper.
(The threshold is at the bottom side of the door…Floor area)

Electrical
Overhead wires from the mast to the main panel that are exposed to the weather may fray and crack. If this occurs, wires should be replaced by a licensed electrician.

Any outdoor overhead service conductor wires should have adequate clearance above the ground (10 feet) and from balcony and windows (3 feet), for safety reasons.

Underground system - Some exterior boxes that are at ground level have a grade line on them. You should insure that the grade remains below this line to prevent moisture from entering the main panel.
