I'm looking for a company or contractor that would install pet doors. What kind of company should I be looking for, and what should I expect out of the job? — Angie's List member Hector Sosa

If you're installing it in an existing door, a handyman should be able to complete the job in less than an hour, says Richard White, owner of highly rated Richard S. White Maintenance in San Jose, Calif.

"You'd want a [remodeling] contractor if you're putting it an exterior wall, especially if it involves cutting into stucco or getting around electrical wiring," he says.

He recommends using pet doors with magnets that only open when a pet with a sensor on their collar approaches. "That keeps out raccoons, stray cats or other animals that might try to get in."

White also suggests keeping an eye on the flap's quality to ensure it keeps a smooth seal and minimizes heating or cooling loss. Pet doors can also be installed in sliding glass or patio doors, according to Linda Cobillas, manager of highly rated A-1 On Track Sliding Door Repair & Installation in Campbell, Calif.

"A lot of homes in this area have sliding glass doors, and a pet door installed there keeps you from having to constantly open and close it," she says. "We'll replace part of the glass with a new piece of glass that has a pet door cutout, so there's no panel. It's airtight, watertight and secure."
