A storm door is an essential part of any home as it helps to protect your main door from harsh weather conditions.
However, over time, it is not uncommon for a gap to develop between the storm door and the frame. This can cause drafts, which may affect the temperature inside your home and lead to higher energy bills. Fortunately, fixing this gap is a relatively easy DIY task that can be done with a few basic tools.
To fix the gap between your storm door and frame, you will need to check and adjust the door hinges, change the weatherstripping along the top and sides of the storm door, and replace the door sweep at the bottom of the door.
These steps will help to ensure that your storm door fits snugly against the frame, preventing drafts and improving energy efficiency.

What Causes a Gap Between a Storm Door and the Frame?
Gaps between storm doors and frames are a common problem that can be caused by several factors. One of the most common causes is a misaligned door due to sagging or settling of the frame. This can cause the door to rub against the frame, creating gaps and drafts.
Another cause of gaps is warping of the door or frame, which can occur due to changes in temperature or moisture levels.
Weatherstripping and door sweeps can also be a factor in creating gaps. If these components are worn or damaged, they may not provide a tight seal, allowing air to leak in and out of the home or even water ingress if the gap is under your door. Additionally, pests such as bugs or rodents can create gaps by chewing through the door or frame.
Why It’s Important to Fix Gaps
Fixing gaps between storm doors and frames is important for several reasons. One of the most significant reasons is energy efficiency.
Gaps can allow warm or cool air to escape from the home, making it more difficult to maintain a comfortable temperature and leading to higher energy bills.
Gaps can also allow drafts and moisture to enter the home, which can lead to discomfort and potential damage to the interior. Additionally, gaps can create an entry point for pests, which can cause damage to the home and pose a health risk to occupants.
How To Fix A Gap Between Storm Door and Frame
Measuring the Gap
Before you start making any adjustments, you need to measure the size of the gap. Use a tape measure to measure the distance between the door and the frame at the top, middle, and bottom of the door. Take note of the largest gap measurement.
Adjusting the Hinges
If the gap is larger at the top or bottom of the door, you may need to adjust the hinges. Tightening or loosening the screws on the hinges can help move the door up or down. Use a level to make sure the door is straight before tightening the screws.
Replacing the Weatherstripping
If the gap is along the sides of the door, you may need to replace the weatherstripping. Remove the old weatherstripping and measure the length of the gap. Cut a new piece of weatherstripping to fit and install it along the sides of the door.
Applying Caulk
If the gap is too large to be fixed with weatherstripping, you can use caulk to seal the gap. Apply a bead of caulk along the edge of the door where it meets the frame. Smooth the caulk with a caulk smoothing tool or your finger.
Installing a Door Sweep
If there is a gap at the bottom of the door, you can install a door sweep to help seal it. Measure the length of the gap and cut a door sweep to fit. Install the door sweep along the bottom of the door using screws or adhesive.
Remember to use shims to help adjust the door if needed. These can be inserted between the door and the frame to help move the door closer to the frame. With these steps, you should be able to fix the gap between your storm door and frame and ensure a tight seal.
Securing the Door
If your storm door is sagging or has a gap between the door and the frame, it may be due to loose screws or worn-out hardware. Securing the door can help prevent further damage and keep your home secure. Here are some tips to help you secure your storm door.
Tightening the Screws
The first step in securing your storm door is to tighten all the screws. Check the screws on the hinges, latch, and handle. If any of the screws are loose, use a screwdriver to tighten them. Make sure to tighten the screws until they are snug, but don’t overtighten them, as this can cause the door to warp or crack.
Adding More Screws
If tightening the screws doesn’t solve the problem, you may need to add more screws. You can use pan head screws to secure the door to the frame. First, remove the existing screws from the hinges, latch, and handle.
Then, drill pilot holes for the new screws, making sure to use a drill bit that is slightly smaller than the screws. Finally, insert the new screws and tighten them until they are snug.
Replacing the Hardware
If the screws are tight and adding more screws doesn’t solve the problem, you may need to replace the hardware. Look for hardware that is specifically designed for locking storm doors, as this will provide the best fit and security. When replacing the hardware, make sure to follow the manufacturer’s instructions carefully.
Preventing Gaps In The Future
To avoid having gaps between your storm door and frame in the future, it is important to perform regular maintenance, trim the door if necessary, and realign the door if it becomes misaligned.
Regular Maintenance
Performing regular maintenance on your storm door can help prevent gaps from forming. Here are some maintenance tips:
- Lubricate hinges and moving parts with a silicone-based lubricant to prevent rust and ensure smooth operation.
- Check the weatherstripping along the top and sides of the door for cracks or wear and replace as necessary.
- Inspect the door sweep at the bottom of the door and replace if it is damaged or worn.
Trimming the Door
Sometimes, a gap between the storm door and frame can be caused by the door being too large for the opening. In this case, you may need to trim the door to fit.
- Measure the gap between the door and frame and mark the excess material to be trimmed.
- Use a saw to carefully trim the excess material from the door.
- Sand the edges of the door to smooth any rough spots.
Realigning the Door
If your storm door becomes misaligned, it can cause gaps to form. Here are some steps to realign the door:
- Check the hinges and hinge pins to make sure they are tight and not loose.
- Use a level to check if the door is level both vertically and horizontally.
- If the door is not level, adjust the hinges by tightening or loosening the screws until the door is level.
- Check the door latch to make sure it is aligned with the strike plate and adjust as necessary.
By following these tips for regular maintenance, trimming the door if necessary, and realigning the door if it becomes misaligned, you can help prevent gaps from forming between your storm door and frame in the future.
