Introduction
A cold breeze near your front door isn’t just uncomfortable—it’s a sign your home is losing heat and energy.
Whether your door is decades old or relatively new, gaps, worn seals, and poor insulation can all contribute to draughts that chill your space and inflate your heating bills. The good news? Draught-proofing your front door is a cost-effective way to improve comfort and reduce energy loss.
Why Draught-Proofing Is So Important
Keeps Warm Air In
Even the smallest gaps can let cold air in and warm air out, making your heating system work harder. Effective draught-proofing improves your home’s thermal performance.
Saves Energy & Money
According to the Energy Saving Trust, properly sealing up doors and windows could save the average UK household up to £60 per year.
Reduces Damp and Mould Risk
Draughts cause uneven temperatures that can lead to condensation and moisture build-up—ideal conditions for mould.
Improves Comfort Instantly
You’ll notice the difference immediately. No more standing near a cold entryway or hearing wind whistle through door gaps.
A warm home starts at the front door—seal it properly, and the whole house benefits.
Common Draught Entry Points
Around the Frame
Wood can warp and uPVC can shrink over time, leaving visible or invisible gaps.

Letter Plates
One of the most common sources of heat loss, especially if it’s loose or poorly insulated.
Keyholes
Keyholes often allow a direct draught path into your hallway.
Thresholds
Even modern doors may have slight gaps at the bottom unless sealed with threshold strips or brush seals.
How to Identify a Draught
Visual & Touch Test
On a cold day, feel around the doorframe for a noticeable change in temperature or breeze.
Smoke or Candle Test
Light a candle or stick of incense and pass it near the door edges—movement in the flame/smoke means air is coming through.
Check Light Gaps
Stand outside in the dark and have someone shine a torch from inside—if light shines through, air can too.
Draught-Proofing Methods
Self-Adhesive Foam or Rubber Seals
These are easy to apply around door frames and are great for quick fixes.
Brush Strips or Door Bottom Seals
Install these along the bottom of the door to block air that sneaks in underneath.
Letterbox Draught Excluders
Spring-loaded or bristle-style covers can be installed behind or over existing letter plates.
Keyhole Covers
Small metal discs that swing across the keyhole when not in use—cheap, easy, and effective.
Heavyweight Draught Excluder Rolls
Placed along the inside of the door at the bottom—simple but effective, especially in older homes.
When Should You Replace the Door Instead?
Signs It’s Time for an Upgrade:
- The frame is warped or rotting
- The door no longer fits snugly or closes easily
- There’s visible damage or large gaps
- You still feel cold despite sealing efforts
