Title:
5 Signs It’s Time to Replace Your Old Pet Door

Body:
A pet door is something most homeowners install and forget about—until problems start to appear. Like any product that gets used every single day, pet doors experience wear and tear over time. If your current pet door isn’t performing like it used to, it may be time to consider an upgrade.

At Moore Pet Supplies, we’ve spent 30 years helping pet owners recognize when their pet door is helping their home—and when it’s hurting it. Here are five clear signs that your old pet door may need to be replaced.

1. You Feel Drafts or Notice Temperature Changes
One of the most common signs of a failing pet door is a noticeable draft. If you feel cold air coming in during winter or warm air during summer, your pet door’s seal may no longer be effective.

Over time, flaps can warp, seals can weaken, and gaps can form. This allows outside air to enter your home, making your heating and cooling systems work harder and increasing your energy bills.

2. The Flap Is Cracked, Warped, or Stiff
Pet door flaps are designed to be flexible and durable, but years of use and exposure to the elements can cause them to deteriorate. A flap that has become brittle, cracked, or permanently bent won’t seal properly.

This not only affects energy efficiency but can also make it harder or uncomfortable for your pet to use the door.

3. Your Pet Hesitates to Use It
Pets are creatures of habit. If your dog or cat suddenly becomes hesitant to use their pet door, it could be a sign that something is wrong.

Damaged flaps, sharp edges, or increased resistance can make the door difficult or unpleasant for your pet. Replacing the door restores ease of use and encourages your pet’s independence.

4. The Frame Is Loose or Damaged
A solid frame is essential for both performance and security. If your pet door frame is loose, cracked, or no longer secure in the door or wall, it can compromise insulation and stability.

A weak frame can also worsen over time, especially with frequent use by larger or more active pets.

5. Your Pet Door Is Simply Old and Outdated
Pet door technology and materials have improved significantly over the years. Older pet doors often lack the insulation, sealing, and durability of modern designs.

Upgrading to a newer, high-quality pet door can improve energy efficiency, increase comfort, and provide better long-term reliability.

The Benefits of Upgrading
Replacing an old pet door doesn’t just fix problems—it improves your home and your pet’s daily life. A new, well-built pet door provides better insulation, smoother operation, and improved durability.

At Moore Pet Supplies, we’ve helped customers upgrade their pet doors for three decades. Our experience ensures you’ll find a solution designed for comfort, performance, and long-term use.

If your current pet door is showing any of these signs, now may be the perfect time to replace it and give your pet—and your home—the upgrade they deserve.
