Refund and Returns Policy
Endura Flap, a brand of Patio Pacific, Inc.
This policy covers orders placed at enduraflap.com. Orders placed on Amazon, at PetDoors.com, or through a dealer are returned under that seller's policy, not this one.
Buying a pet door means planning to cut a permanent hole in your house, and wanting to be certain before you commit to that is reasonable. This policy is built around it. You get 90 days, and holding the door up in the opening to check the fit does not cost you the return.

The short version
- You have 90 days from delivery to request an RMA, our return authorization number, on most items, and you get the item price back. It is the request that has to happen inside the 90 days, not the package arriving back here.
- We pay return shipping if the item is defective, damaged in transit, or not what you ordered.
- You pay return shipping if you changed your mind or ordered the wrong item. If that order shipped free, we may also deduct what the outbound shipping cost us.
- Items have to come back complete and in resellable condition. We can decline one that does not.
- Installed doors and custom-built items cannot be returned.
- We do not do exchanges. Return the item, then place a new order.
- Nothing comes back without an RMA number.
Return window
The clock starts the day the carrier records your order as delivered.
You have 90 days from that date to request an RMA for a refund of the item price. It is the request that has to reach us inside the 90 days. The item does not have to be back at our warehouse by day 90, and it does not even have to be in the mail by then.
Your window is set on the day you request the RMA, as long as you ship within 14 days of receiving it. If you miss that 14-day window, the date we receive the item is what counts instead. See How to start a return.
This policy is also linked at checkout, before you pay.
There is no restocking fee for changing your mind. What we require instead is that the item come back complete and in resellable condition, and we can decline a return that does not. That is covered in The condition we accept. What a change-of-mind return can cost you is shipping, and that is covered in Who pays return shipping. On an item that is defective, damaged in transit, or not what you ordered, you pay nothing at all, and that is covered in Damaged, defective, or wrong item.
The condition we accept
Returned items must come back in resellable condition. Concretely, that means:
- Complete. Every part that shipped with the door is in the box: frame or frames, flap, locking cover, hardware pack, screw covers, cutting template, and instructions.
- Unmodified. Nothing cut, trimmed, drilled, sanded, painted, or re-finished.
- No installation residue. No caulk, sealant, adhesive, paint, or foam on the frame, and no added screw holes.
- Undamaged. No dents, bends, cracks, or scratches beyond what a new unit has.
- No pet damage. No chew marks or claw punctures on the flap or frame.
- Repackable. Original box, or a box that protects the item as well as the original did.
Two things that do not cost you anything:
- A fit check is fine. You can hold the door in the opening, mark it, and take it back out. Temporarily setting it in place to test fit does not void your return as long as the item comes back meeting the six points above.
- Dust and pet hair are fine. We clean returned items. We do not charge a fee for a dirty item.
We can decline a return that comes back incomplete or modified. If that happens, we tell you what we found and what your options are before we do anything with your refund. You will not find out from the refund amount.
What you cannot return
Installed doors. Once a door has been mounted, sealed, screwed in, or framed into a wall, door, or panel, it cannot come back. A fit check is not an installation. See The condition we accept.
Custom-built items. An item is custom when it is built to a measurement or specification you give us. That means:
- any panel or insert cut to your track height, door height, or glass opening
- any in-the-glass unit
- any item built to a dimension that is not one of our published stock sizes
- any item we modify at your request
Made to order is not the same as custom. We build most doors after you order them. If your item is a published stock size in a published color and flap option, it is returnable under this policy even though we made it for your order. Door mount and wall mount doors in standard sizes are returnable. Cut-to-size panel inserts and in-the-glass units are not.
Custom items are marked final sale on the product page, and that marking appears as soon as you select a custom option.
Options and upgrades added to a made-to-order item. Some products let you add an option or an upgrade that is not one of our published stock choices. When you do, that addition goes onto the order we send to the factory or the supplier who builds the item, and we are charged for it there. Those additions are final sale, and an item built with one cannot come back.
Items damaged by a pet or by misuse. Chewed, clawed, or forced parts cannot be returned for a refund, and the Endura Flap warranty does not cover them either. Saying that here is better than sending you to a page that turns you down. What we can do is sell you the part. Replacement flaps and parts are available at any time. Email or call us with your door model and we can point you to the right one.
Damaged, defective, or wrong item
Visible damage or the wrong item. Contact us within 7 business days of delivery. Send photos of the item, the damage, and the shipping box including the label. We will replace it, repair it, or refund it. You pay nothing.
Concealed damage found at installation. Pet doors often sit in a box for weeks before anyone opens them. If you find shipping damage when you unbox the item to install it, contact us within 30 calendar days of delivery. Keep the box and all packing material. We may need photos of both to file a carrier claim.
We pay all shipping on these returns, and no fee is deducted from your refund.
Past 30 days we can no longer document shipping damage well enough to file a carrier claim, so damage reported after that is handled as a defect rather than as a shipping problem. Which remedy you get then is the next section, and inside 90 days it is your choice.
A defect inside the first 90 days: you choose
If your door fails inside the first 90 days after delivery, you decide which remedy you want. Return it for a refund under the Refund Policy, or keep it and take the warranty repair, which means we send you the parts at no cost to you. It is your call, not ours, and asking about one does not give up the other. After 90 days the return window has closed and the warranty is the route, for the life of the product.
Who pays return shipping
This is the part most people ask about, so here it is plainly.
We pay when the problem is ours:
- the item is defective
- the item arrived damaged
- we shipped the wrong item, size, or color against your order
We email you a prepaid label and you owe nothing.
You pay when you changed your mind:
- you ordered the wrong size
- you no longer need it
- it does not fit your door or your pet
- any other return that is not a defect, a shipping damage, or our error
We will email you a prepaid label and deduct its cost from your refund, or you can ship it back with your own carrier. If you ship it yourself, use tracking. You are responsible for the item until it reaches us.
Free U.S. shipping is the shipping that brings the door to you. It covers the outbound leg of your order and it has never covered return shipping.
Original shipping charges. If you paid an outbound shipping or freight charge, that charge is not refunded on a change-of-mind return.
If your order shipped free. On a change-of-mind return of an order that shipped under free U.S. shipping, we may deduct what that outbound shipment actually cost us from your refund. It is not an automatic deduction. When we do apply it, we tell you the amount before the refund goes through, so it is never a surprise on your statement.
How to start a return
- Request an RMA. Email customerservice@enduraflap.com or call (800) 826-2871. Have your order number ready.
- We issue an RMA number and a return address. Do not use the address printed on the box you received. Some items go to a different warehouse.
- Ship within 14 calendar days of the date on your RMA. Include everything listed in The condition we accept. Write the RMA number on the outside of the box.
- Pack it properly. An item damaged in return transit because it was packed loose or in an undersized box may not come back resellable. If that happens, we tell you before we process your refund.
Items sent back without an RMA number are refused at the dock. We cannot refund an item we cannot identify.
If you miss the 14-day ship-by window: your RMA expires. Contact us and we will issue a new one at no charge. Your return is then measured by the date we actually receive the item, not by your original request date.
Refunds
Inspection. We inspect returns when they arrive at our warehouse and we email you the result, approved or not, with the reason and any deduction. We process returns during the business week, so a box that lands on a Friday is looked at the following week.
Payment. Approved refunds go back to your original payment method within 10 business days of approval. That is the commitment, and we would rather hold a number we can hit in a busy week than publish a faster one and miss it.
We refund to the original payment method only. We cannot send a refund to a different card, account, or person.
What you get back:
- the item price
- sales tax charged on that item
What is deducted, when it applies:
- the cost of the return label, if we provided one on a change-of-mind return
- our outbound shipping cost on a change-of-mind return of an order that shipped free, if we apply it (see Who pays return shipping)
- original outbound shipping you paid is not refunded
Bank posting time. Once we send the refund, your bank or card issuer controls when it appears, usually 3 to 10 days. That gap is on their side, not ours. If more than 15 business days have passed since we told you the refund was approved and you still do not see it, email customerservice@enduraflap.com.
Exchanges
We do not offer exchanges. Return the item you have, and place a separate order for the one you want. That is faster than an exchange, because your new order goes into production immediately instead of waiting on the return to arrive.
International orders
We do not sell or ship to the European Union, the European Economic Area, the United Kingdom, or Switzerland.
For international orders we do accept:
- We pay the freight when the fault is ours. If the item is defective, arrived damaged, or is not what you ordered, we pay to get it back and to get the right one to you, wherever we shipped the original order. Outside the continental United States is no exception. The Warranty follows the same rule on covered replacement parts.
- You pay return shipping on any return that is not a defect, damage, or our error.
- Duties, taxes, and customs fees are not refundable by us. Some countries refund them on export. That claim is between you and your customs authority. The same is true of duties on a warranty part.
- We have to receive an international return within 100 days of your order date. An international refund has to be matched back to the original charge, and banking rules limit how long that stays possible. Request your RMA inside the 90-day window and ship it promptly and this will not come up.
Order cancellations and shipping delays
Cancelling an order, revised ship dates, and what happens if we cannot ship in the time we stated are covered by the Shipping Policy. Refund timing on a cancelled order is the same as on any other refund, and it is under Refunds above.
Pricing and typographical errors
Prices, specifications, and product descriptions on this site are occasionally wrong. What we do when that happens, including your right to a full refund and to buy the item at the correct price, is set out under Prices and errors in our Terms & Privacy. We keep the full statement in one place so there is only one version of it.

Product Details
Product Details
The Pet Door Guys In-The-Glass Pet Door is engineered to replace one insulated glass panel within your existing sliding glass door, French door, or sidelight. Rather than adding a framed insert, this solution maintains the original door frame and preserves the visual continuity of your home.
Each unit is constructed with tempered dual-pane glass filled with argon gas for insulation and includes a factory-installed Endura Flap. Optional Low-E or tinted glass selections allow the new unit to more closely match your existing door configuration.
Because this is a fully custom insulated glass unit, it is not a do-it-yourself project. A professional glazier must measure the net glass size and complete the installation. Installation materials are not included, as professional glass installers typically supply the appropriate glazing materials.
Production begins once the completed order form is approved, with an estimated build time of approximately 5 weeks plus transit from Washington State. Units are available in white or beige and ship within the lower 48 United States only.
Clear Glass
A straightforward insulated glass option that maintains visibility while providing everyday thermal performance.
Solarban® 60 Glass
Solarban® 60 offers a clear, neutral appearance with enhanced solar control designed to help reduce heat transfer while maintaining strong natural light transmission.
Solarban® 70 Glass
Solarban® 70 provides increased solar heat control for homes exposed to stronger sun and warmer climates, while still maintaining a clean appearance and excellent visibility.
