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

Most pet doors are made to be installed in a door rather than a wall, says David Zora, owner of A-rated Handyman Services of Pittsburgh. Any experienced handyman should be able to do the installation, he says, adding that homeowners should purchase the pet door themselves and consult with the installer to make sure the entry door can be fitted with a pet door.

He says metal doors are difficult to cut effectively and paneled doors can present problems because the pet door's exterior frame often will not match the entry door's profile.

The work, which involves taking the existing entry door down, cutting a hole in it and installing the pet door, takes about two hours depending on the type of door.

He also adds energy efficiency and security are other considerations. Once installed, Zora says it's important to make sure the pet door is properly sealed with silicone caulk or a gasket to prevent moisture penetration from damaging the door.

As far as security, Zora says homeowners shouldn't worry. "Pet doors are too small for anyone to gain access," he says.
