"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

A carpenter or handyman with a solid track record is the best company to install a pet door, says Skip Wyatt, owner of highly rated Mr. Handyman of Upper Fairfield County in Connecticut. "The most important thing is having expertise in the kind of work you want," he says.

Wyatt encourages homeowners to purchase the pet door before he arrives, and he says the job typically takes less than two hours. While costs vary, he says installation typically ranges from $200 to $300.

Gerald Nesbeth, owner of A-rated Queen City Construction Inc. in New Rochelle, N.Y., says pet doors can be a security issue.

"If you have a large dog or pet and you need a larger door, someone could possibly use that as an entry point," he says. "Then again, you want to allow your pet to come and go while you're not at home. It's about what you value the most."

Consumers should also look for energy-efficient pet doors, such as models that feature insulation, Wyatt says. "It's still ultimately an opening, so there's no way you can keep it as airtight as not having the pet door," he says.
