Best pet doors still allow draft
"I'm looking for a company or contractor to 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
"Installing the pet door into a door is always better," he says. "If you sell your home, it's easier to replace the door than repair a wall, and there are structural, electrical and plumbing issues with exterior walls."
Any possible leaks are also much easier to detect in a door than in a wall. Caulking the edges where the new pet door meets the "people" door is crucial to preventing moisture infiltration. But remember, he adds, once a hole is cut in a door, it can never be repaired to its original state.
Most customers purchase the dog door themselves, and the average job takes about 90 minutes, Richie says.
Consider two additional factors: energy loss and security. Even though some models feature double flaps for a better seal, even the best pet door will introduce a draft, which will lead to some heating and cooling loss.
"The security issue is also a reasonable concern, but most doors feature a slide-in security panel," Richie says. However, leaving even the smallest of pet doors open means that an average-sized adult can reach in and unlock the handle or dead bolt.
