There are several reasons why your front door or entrance door might be leaky:
New wooden door warped: Especially with new wooden doors, the wood can still “work” during the first two heating seasons. This means the wood absorbs and releases moisture, which can cause the door leaf to warp slightly. Don’t worry: this is normal and can usually be fixed easily.
Old door with leaky construction joint: In older doors, the construction joint—the transition between the door frame and the masonry—can become leaky. This allows air and moisture to enter.
Damaged seal: The seal around the door can become porous or damaged over time, so the door no longer closes tightly.
Severely warped old door: With very old doors, the door leaf may have warped so much over the years that repair is hardly possible.
Here’s a quick guide on how you can fix the problem depending on the cause:
If your new wooden door is leaky, there’s usually no need to panic. Most new doors have adjustable hinges, making it easy to reposition the door leaf:
1) Check where the door isn’t closing tightly.
2) Adjust the door hinges according to the manufacturer’s instructions.
3) Test if your front door is now sealed.
Often, a small adjustment is all it takes for your door to close perfectly again.
If the joint between the frame and masonry is leaky on your old wooden or entrance door, try this:
1) Locate the leaky spots around the door frame.
2) Drill small holes in the joint at specific points.
3) Fill the cavities with special foam.
4) Seal the holes cleanly afterward.
This prevents air and moisture from entering your home.
A damaged or porous seal is a common cause of leaky doors. Replacing it is usually straightforward:
1) Carefully pull out the old seal.
2) Insert a new seal with the correct profile.
3) Make sure the seal fits snugly all around.
A new seal often makes a big difference.
If your wooden or entrance door is severely warped and none of the above solutions help, replacing it is usually the best option. New doors built to current standards offer excellent insulation, security, and durability—and can be designed to match the look of your original door if you wish. Investing in a new front door pays off in the long run.
Whether your wooden door is new or old, leaky doors can usually be fixed with just a few steps. First, check the cause: is the door warped, is the construction joint leaky, or is the seal damaged?
