The Magnador two-way pet door and MagnaFlap are built to last, giving your dog the freedom to come and go as they please while keeping your home sealed from the elements. These doors create a tight seal to keep the air conditioning in and the weather out, all while giving your pet the independence they love.
But like any product that faces daily use and exposure to the elements, a little maintenance goes a long way. Weather, wear and tear, and even your pet's occasional boredom biting can eventually lead to parts that need attention.
The good news? We stock all the replacement parts you need—flaps, frames, and hardware—so you can keep using your Magnador year after year. And with these three simple maintenance tricks, you can significantly extend the life of your pet door.
Tip 1: Add a Door Bumper for High-Energy Dogs
If you have an enthusiastic dog who comes barreling through the door at full speed (we're looking at you, Labrador owners), those high-impact swings can take a toll on both the door and the frame over time.
Here's a simple, inexpensive fix that makes a big difference:
What you need: 2-3 small pieces of adhesive-backed rubber gasket material. You can find this in the weatherstripping section of any home improvement store—it's the same material used for sealing around windows and doors.
Where to install: Place the rubber gasket material on the bottom of the rain shield and on the inside frame of the door.
Why it works: When your dog swings the door completely open, the rubber gasket acts as a bumper to soften the impact. This protects both the door panel and the frame from damage, significantly extending the life of your Magnador.
This is especially important for large, energetic breeds that don't exactly take their time going in and out. A few dollars worth of rubber gasket material can prevent hundreds of dollars in door replacement costs.

Tip 2: Fix That Clicking Sound (Check Your Locking Knobs)
Does your Magnador make a clicking or scraping sound when your dog goes through? This is one of the most common issues we see, and it's almost always caused by the same thing: improperly retracted locking knobs.
The problem: Your Magnador has two locking knobs that, when extended, lock the door in place. When fully retracted, these knobs should be completely out of the way, allowing the door to swing freely. If they're not fully retracted—even just slightly extended—the door can catch on them as it swings.
What happens: This creates resistance every time your dog uses the door. Over time, especially with strong dogs making numerous trips, this catching and resistance will cause premature door failure.
The fix: Verify that both locking knobs are fully retracted. If you hear clicking or scraping, this is the first thing to check. It's a simple adjustment that takes seconds but prevents significant damage down the road.
Pro tip: Make it a habit to check your locking knobs periodically, especially if you've recently locked the door and then unlocked it. It's easy to not quite retract them all the way, and that small oversight can cause big problems over time.

Tip 3: Prevent Magnet Rust With a Moisture Seal
The magnets in your Magnador are what create that secure seal when the door closes, keeping drafts and weather out of your home. But magnets and moisture don't mix well—over time, moisture can cause rust, which weakens the magnetic seal and shortens the magnet's lifespan.
Here's a quick trick to prevent this:
What you need: A small amount of silicone caulk (the kind used for bathrooms and kitchens works perfectly).
How to apply: Spread a thin layer of silicone caulk along the top of the magnet. Use your finger to smooth it out, working it into and around the magnet.
Why it works: The silicone caulk creates a moisture seal that prevents water from getting into the magnet. This simple barrier dramatically extends the life of your magnets by preventing rust before it starts.
When to do this: This is a great preventive measure to take when you first install your Magnador, or anytime you're doing routine maintenance. It takes just a couple of minutes and can add years to your magnet's life.

Even with the best maintenance, parts eventually wear out—and that's completely normal. The beauty of the Magnador system is that you don't have to replace the entire door when one component wears out.
