How to Measure the Flap Opening to Get the Right Size Replacement
Getting the properly sized replacement flap is crucial for your pet door to function properly. Here are the steps to accurately measure your existing flap opening so you can find the right replacement:
Materials Needed
- Tape measure
- Pencil and paper
Instructions
- Remove the existing flap completely from the pet door frame.
- Using the tape measure, measure the height of the flap opening from top to bottom. Record this measurement.
- Now measure the width of the opening from side to side. Record this as well.
- Check that the opening is square by measuring the diagonals. They should be equal if the opening is square.
- Compare your measurements against the size chart for the replacement flap to determine the proper size to order.
Tips
- Measure to the nearest 1/8 inch for accuracy.
- If the opening is not square, measure width at both top and bottom and use smaller width.
- If unsure between two sizes, opt for the larger size replacement.
Following these instructions carefully when measuring will ensure you select just the right replacement flap size for your pet door. This will allow for proper installation and functionality.
How to Remove the Old Flap for Installation of a New One
Removing the old, worn out flap is an important first step when replacing it with a new pet door flap. Here is a step-by-step guide to properly remove the old flap:
Materials Needed
- Phillips head screwdriver
- Pliers
Instructions
- Locate the screws around the edges of the flap. There are typically at least 4 screws.
- Using the screwdriver, remove the screws and place them in a small container so they don't get lost.
- Try to gently pry or pull the edges of the flap away from the frame.
- If the flap won't budge, look for any additional screws or clasps, especially along the sides.
- For plastic flaps with snapped in edges, use the pliers to gently pull and rock the flap to pop it loose.
- Once removed, inspect the flap opening for any remaining screws, damage, or blockages.
- Clean around the opening thoroughly so the new flap can seal properly.
Troubleshooting
- Soak rusted screws in WD-40 to loosen before removing.
- Deal with any damage or blockages before attempting to install replacement flap.
Taking your time to follow these steps will allow you to successfully remove the old flap without damaging the door frame. This will prep the opening for easy installation of your new replacement flap.
How to Install the New Flap onto the Pet Door Frame
Once you've removed the old, worn out flap, installing a new one onto the pet door frame is straightforward. Follow these steps for proper installation:
Materials Needed
- New pet door flap
- Screwdriver
- Drill with small drill bit (if needed)
Instructions
- Align the new flap properly over the opening, making sure it is oriented correctly.
- If needed, pre-drill small pilot holes through the screw holes on the flap frame.
- Place a screw through each corner hole and loosely tighten with the screwdriver.
- Check that the flap is centered and level in the opening before tightening down fully.
- Insert screws through the remaining holes along the sides and securely tighten them all.
- Test the flap to ensure it opens freely and the magnetic or spring closure works properly.
- Make any adjustments as needed to the flap's position or hardware until properly installed.
Tips
- Use the existing holes if lining up properly with the new flap.
- Apply weatherstripping tape for an airtight seal.
- Lubricate the hinge pin if needed for smooth motion.
Taking care to align and install the flap correctly will ensure it operates smoothly while sealing out drafts and pests.
How to Get the Flap to Properly Lock and Latch
A flap that doesn't properly lock and latch can let in cold drafts, pests, and stray animals. Here are some tips to get the flap securely closing:
Assess the Closure
- Determine if the flap has a magnetic closure, spring closure, or flap lock.
- Test to see if the closure is lining up correctly when the flap is closed.
- Look for damage, missing magnets, broken springs, or bent locking arms.
Adjust the Closure
- For magnetic closures, make sure magnets are aligned and free of debris.
- For spring closures, adjust spring tension if too loose or tight.
- For flap locks, straighten bent locking arms and ensure they catch properly.
- If closure hardware is damaged, replace with identical closure mechanisms.
Check Alignment
- Inspect that the flap is hanging straight and closing flush against the frame.
- Adjust hinge mounting screws to realign if needed.
- Add weatherstripping for an air-tight seal with the frame when closed.
Getting the flap aligned properly combined with closure hardware in good working order will result in the flap latching securely every time it closes. This will keep unwanted elements out of your home.
How to Make Sure the Flap is Keeping Drafts Out
A pet door flap that doesn't seal properly against the frame will allow cold drafts to enter your home. Here are some tips to check for and prevent drafts:
Inspect the Seal
- Make sure the flap is aligning flush against the frame when closed.
- Check for gaps, especially at the corners and hinge side.
- See if daylight is visible around the edges when closed.
Test for Drafts
- Light a stick of incense and hold it near the closed flap, moving around the edges.
- Smoke being blown indicates an air leak where drafts can enter.
- An infrared thermometer can also find temperature differences around the flap.
Improve the Seal
- Adjust the flap alignment or latching mechanism if needed.
- Apply silicone caulk around the frame to seal any gaps.
- Install self-adhesive weatherstripping around the opening.
- Consider replacing foam inserts around the flap if worn out.
Taking steps to ensure a tight seal will keep cold drafts from seeping in around your pet's door flap. This will help keep your home warm and energy costs down.
