Questions

How do I measure my old flap to order the right replacement size?

Measure the flap panel itself, not the hole it covers and not the outside of the frame. Take the width across the flap at its widest point, then the height from the top edge, including the section that sits under the retainer, down to the bottom edge.

Then count the holes along the top edge and measure the distance between the centers of the two outermost holes. Flap dimensions repeat across brands but hole patterns do not, so that spacing is usually what tells us which flap is actually yours. The size guide on the product page lists the flap dimensions for each size we carry, so you can check your measurements against it before ordering.

Can I buy just one flap for a double flap pet door?

Yes. On a double flap door the two flaps are separate parts, so you can replace one and leave the other in place. That is common, because the exterior flap takes the weather and the UV and usually wears out first.

Order the same size as your door and tell us which side you need if the two differ. If both flaps are the same age it is worth replacing them together. A new flap sits against the frame more tightly than a relaxed older one, and mixing the two can leave the seal uneven.

Does a replacement flap come with magnets and hardware, or just the flap?

Our replacement flap kits arrive ready to install. The flap ships with the parts needed to fit it to your door, so you are not sourcing magnets, rivets or retaining strips separately.

If you would like to add extra magnets for a firmer close, those are available separately as well.

If you would like to add extra magnets for a firmer close, those are available separately as well.
How do I know which replacement flap fits my pet door? Replacement flaps are matched to the door they came from, not to your pet, so the brand and model of the door decide which flap you need. The fastest way to identify yours is to look at the frame. Most manufacturers mold or stamp a brand name and a size letter into the inside frame, usually near a corner or along the bottom rail. If nothing is legible, measure the flap itself rather than the hole it covers: width and height of the flap panel, plus the number and spacing of the holes along its top edge. Those three numbers identify almost every flap we carry, and you can check them against the size guide on the product page. Send us a photo of the frame and the flap together and we will confirm the match before you order.
Is my pet door flap covered under warranty? Warranty coverage on a pet door flap is set by the company that made the door, and the terms vary widely between manufacturers. For that reason the fastest and most reliable answer will come from the original manufacturer of your pet door. They can tell you what your flap is covered for and what they need in order to process a claim. If you bought the door from us and are not sure who made it, send us a photo of the frame and we will identify the brand so you know who to contact. We can also help you order a replacement flap directly if you would rather not wait on a warranty claim.
Should I replace just the flap or the whole pet door? Replace the flap when the frame is sound and the problem is the flap: cracks, splits, a permanent curl, or a seal that no longer closes flat. That is the common case, and it costs a fraction of a new door. Replace the whole door when the frame itself is damaged, when the tunnel no longer fits your wall, or when you need a different size because your pet has grown or changed. If you are unsure, a photo of the door installed, taken from the inside with the flap hanging naturally, usually tells us which one you need.
