Drafty doors can make your home uncomfortable, increase energy bills, and allow dust and pests to enter. It is important to seal these drafts to maintain energy efficiency and improve indoor comfort.
In this blog, we will discuss common causes of drafty doors and various methods for door repair in NYC.
Causes of Drafty Doors
Before you start fixing drafty doors, it’s essential to identify the source of the problem. The most common causes include:
- Worn Weatherstripping – Over time, weatherstripping loses its effectiveness, leading to air leaks.
- Improperly Installed or Aged Doors – Doors that don’t fit properly within their frames can leave noticeable gaps.
- Damaged Door Sweeps – A worn-out door sweep can allow air to pass through the bottom of the door.
- Warped or Shrinking Door Frames – Wood can expand and contract due to humidity and temperature changes, causing gaps to form.
- Cracked or Damaged Door Panels – Structural damage in the door itself can create openings for drafts.
Step-by-Step Methods to Repair Drafty Doors
1. Inspect the Door for Drafts
Before applying any fixes, thoroughly inspect your door to identify the location of drafts. Here’s how:
- Close the door and run your hand along the edges to feel for air movement.
- Use a candle or incense stick and hold it near the door edges. If the flame flickers or smoke wavers, you’ve found a drafty spot.
- Shine a flashlight from one side of the door while a helper observes from the other side for light leaks.
2. Replace or Install Weatherstripping
Weatherstripping is one of the most effective ways to seal gaps around doors.
Materials Needed:
- Self-adhesive foam weatherstripping
- Rubber or vinyl weatherstripping
- Scissors or a utility knife
- Measuring tape
Steps to Apply:
- Remove the old weatherstripping if it’s damaged or worn out.
- Clean the surface where the new strip will be applied to ensure proper adhesion.
- Measure the door frame and cut the new weatherstripping to the correct length.
- Press the weatherstripping firmly into place along the edges of the door.
3. Install or Replace a Door Sweep
A door sweep prevents drafts from entering beneath the door.
Materials Needed:
- New door sweep (brush-style or rubber gasket)
- Screwdriver or drill
- Measuring tape
- Hacksaw (if cutting is needed)
Steps to Apply:
- Remove the existing door sweep by unscrewing it.
- Measure the width of the door to ensure the new sweep fits properly.
- Attach the new sweep using screws or adhesive, ensuring it seals tightly against the floor.
4. Apply Caulk to Seal Gaps
If there are small gaps around the door frame, caulking can be an effective solution.
Materials Needed:
- Exterior-grade silicone caulk
- Caulk gun
- Putty knife
Steps to Apply:
- Clean the gaps around the door frame to remove dirt and debris.
- Load the caulk gun and apply a smooth bead of caulk along the gaps.
- Use a putty knife to smooth out the caulk for a clean finish.
- Allow the caulk to dry completely before using the door.
5. Adjust Hinges to Realign the Door
Sometimes, misaligned doors create gaps that cause drafts.
Materials Needed:
- Screwdriver
- Wood shims (if needed)
Steps to Apply:
- Check the alignment of the door by opening and closing it.
- Tighten or loosen the hinge screws as needed to adjust the door.
- If necessary, place a thin shim behind the hinge to help reposition the door.
- Test the door to ensure it seals properly.
6. Use a Draft Stopper
For a quick and inexpensive fix, consider using a draft stopper, also known as a door snake.
Materials Needed:
- Fabric tube filled with sand, rice, or foam
- Sewing kit or adhesive (if making your own)
Steps to Apply:
- Place the draft stopper along the bottom of the door.
- Adjust as needed to ensure a snug fit.
7. Install a Storm Door
A storm door provides an additional barrier against drafts and enhances insulation.
Materials Needed:
- Pre-made storm door kit
- Screwdriver or drill
- Measuring tape
Steps to Apply:
- Measure the door frame to ensure a proper fit.
- Install the storm door using the provided hardware and instructions.
- Check for any remaining gaps and adjust as necessary.
Additional Tips for Maintaining a Draft-Free Door
- Regularly check weatherstripping for wear and tear and replace it when necessary.
- Keep door hinges tightened to prevent misalignment over time.
- Monitor humidity levels in your home to prevent wooden doors from warping.
- Consider upgrading to an energy-efficient door if your current door is old and structurally compromised.
