FAQ Section
Will a sliding glass pet door affect my door’s locking system?
Many pet door panels come with their own security bar or lock, but you may lose the use of your standard door lock. For the best security, install a supplemental bar lock or consult a locksmith for extra options.
Can I install a pet door in a rental home?
Yes—most sliding glass pet doors are designed for temporary, no-drill installation and can be removed without leaving a mark. Always check your lease and measure your door before ordering.
How do I choose the right size for my pet?
Measure your pet’s height and width at the shoulders, and add 1–2 inches for comfort. Make sure the bottom of the flap is low enough for small pets to step over safely.
Will the panel affect energy efficiency?
Insulated, dual-pane panels are best for extreme climates. Cheaper, single-pane options are less efficient but still much better than a poorly sealed DIY solution.
Can I lock my pet door at night?
Absolutely. All the top-rated panels include a lockout panel or slide-in cover to keep pets in or out, and to prevent entry when you’re away.
