Depending on where you live, national averages can seem like a steal. Rene Artale’s four-bedroom house near Newcastle, in Westchester County, N.Y., suffered some damage during a storm last winter. A tree fell in the yard, damaging her fence, arbor and retaining wall. And heavy snow caused her roof to leak. The repair bills just kept piling up. Removing the tree, $3,800. Repairing the wall, $4,000. Fixing the roof, $3,800. Fixing the picket fence, $2,800. “It’s obscene,” Ms. Artale, 47, said.
How to DIY it: This job can be messy, so protect nearby surfaces by covering them with plastic or cardboard. Spray the springs with garage door lubricant (about
