With Christmas less than a month away, experts are urging zealous decorators to take care when putting up holiday lights this season.

Ladders When it comes to using a ladder, Baluch recommends adhering to the simple 4-1 rule: for every four feet you go up, add one foot of distance between the ladder and the wall. “Never install lights on your own,” Baluch added. “You always want
