Step 1: Cleaning and Preparing the Door
Before you begin the process of sealing your patio door, it’s important to clean and prepare the door surface. This will ensure proper adhesion of the weatherstripping and sealant, allowing for a more effective seal.
Follow these steps to clean and prepare your patio door:
- Start by removing any dirt, dust, or debris from the door frame, bottom track, and surrounding areas. Use a damp cloth or a mild household cleaning solution to wipe down the surfaces.

Step 2: Measuring and Cutting the Weatherstripping
Properly measuring and cutting the weatherstripping is essential for achieving a tight and effective seal around your patio door. Follow these steps to measure and cut the weatherstripping:
- Using a measuring tape, measure the length of each side of the door frame where you will be installing the weatherstripping. Make sure to measure from the inside of the frame.
- Add approximately 10% to the measured length to allow for any stretching or shrinkage of the weatherstripping material. This ensures a proper fit and seal.
- Based on the measurements, cut the weatherstripping to the appropriate length using a pair of scissors or a utility knife. Be careful to make clean and straight cuts.
- For vertical weatherstripping on the sides of the door frame, ensure that the weatherstripping is long enough to extend from the top to the bottom of the frame.
- For horizontal weatherstripping for the top and bottom of the door frame, measure the width of the frame and cut the weatherstripping to fit.
- If necessary, apply adhesive to the back of the weatherstripping to improve adhesion. Follow the manufacturer’s instructions for applying the adhesive, if required.
By accurately measuring and cutting the weatherstripping, you ensure a proper and snug fit, minimizing the potential for drafts, air leaks, and energy loss. Take your time during this step to ensure precise measurements and clean cuts.
Once you have the weatherstripping cut and ready, you can move on to the next step: applying the weatherstripping to the door frame.
Step 3: Applying the Weatherstripping to the Door Frame
Now that you have measured and cut the weatherstripping, it’s time to apply it to the door frame. Follow these steps to properly apply the weatherstripping:
- Starting with one side of the door frame, remove any backing from the adhesive side of the weatherstripping, if applicable.
- Press the weatherstripping firmly against the edge of the door frame, starting at the top and working your way down. Ensure that the weatherstripping is properly aligned and centered on the edge.
- Continue applying the weatherstripping along the side of the door frame, pressing it firmly in place as you go. Avoid stretching the weatherstripping, as this can compromise its effectiveness.
- If the weatherstripping comes in the form of strips or rolls, cut it to fit around any hinges, latches, or other obstructions on the door frame. Make clean and precise cuts to ensure a proper fit.
- Repeat the process for the remaining sides of the door frame, applying the weatherstripping in the same manner. Ensure that each piece of weatherstripping is properly aligned and securely attached to the door frame.
- For the vertical weatherstripping on the sides of the door frame, make sure the weatherstripping extends beyond the top and bottom to fully seal the gaps.
As you apply the weatherstripping, ensure that it creates a tight seal when the door is closed. The weatherstripping should compress slightly, providing resistance against drafts and air leaks. Verify that the weatherstripping does not interfere with the proper operation of the door, allowing it to open and close smoothly.
Once you have applied the weatherstripping to all sides of the door frame, you are ready to move on to the next step: checking for proper seal.
Step 4: Checking for Proper Seal
After applying the weatherstripping to the door frame, it’s important to check for a proper seal. This step ensures that the weatherstripping is effectively preventing drafts, air leaks, and energy loss. Follow these steps to check for a proper seal:
- Carefully close the patio door and observe the gaps between the door and the weatherstripping. Look for any significant spaces or areas where the weatherstripping may not be making full contact with the door.
- Run your hand along the edges of the closed door, feeling for any air drafts or leaks. Pay close attention to the corners, where gaps may be more common.
- Use a flashlight to examine the door frame from the outside. Look for any light gaps that may indicate areas where the weatherstripping is not sealing properly.
- If you notice any gaps or areas without a proper seal, adjust the weatherstripping accordingly. You may need to reposition or add additional weatherstripping to ensure a tight fit.
- Open and close the door several times to test the effectiveness of the weatherstripping. Listen for any unusual sounds or movements that may indicate a poor seal.
- If necessary, make any necessary adjustments or replacements to achieve a proper seal. It’s important to address any issues promptly to maximize the energy efficiency benefits of sealing your patio door.
By checking for a proper seal, you can identify and address any gaps or issues with the weatherstripping. This step ensures that your patio door is effectively sealed, preventing drafts, air leaks, and energy loss.
Continue to the next step if you need to replace old or damaged seals on your patio door.
Apply a silicone-based weatherstripping sealant around the edges of the patio door to prevent drafts and water leaks. Make sure to clean and dry the surface before applying the sealant for best results.
Step 5: Replacing Old or Damaged Seals
If you have noticed that the existing seals on your patio door are worn out or damaged, it is important to replace them to maintain an effective seal. Here are the steps to replacing old or damaged seals:
- Inspect the existing seals around your patio door. Look for signs of wear, cracking, or deterioration. If the seals are damaged, you will need to remove them before installing new ones.
- Using a putty knife or a screwdriver, carefully remove the old seals from the door frame. Take your time to avoid damaging the door or surrounding areas.
- Measure the dimensions of the removed seals to ensure that you purchase the right size replacements. You can take these measurements to a hardware store or consult with a professional to find the appropriate replacement seals.
- Once you have the new seals, cut them to the proper length using scissors or a utility knife. Ensure that the new seals match the measurements of the old ones.
- Apply the new seals to the door frame, following the same process outlined in Step 3: Applying the Weatherstripping to the Door Frame. Make sure the seals are properly aligned and securely attached.
- Check for a proper seal by closing the door and inspecting for any gaps or areas without a tight fit. Make any necessary adjustments to ensure an effective seal.
By replacing old or damaged seals, you can restore the functionality and energy efficiency of your patio door. Be diligent in inspecting and replacing worn-out seals to maintain the integrity of the seal and prevent drafts, air leaks, and energy loss.
