A draughty front door is a common problem many UK homeowners face, particularly those with older uPVC doors. These draughts often happen because uPVC, while durable, can shift slightly over time due to temperature changes and regular use.

As experts with over 60 years of experience in doors and windows, we’ve created this comprehensive guide to help you tackle door draughts yourself.

Why Door Draughts Matter

A draughty door isn’t just an annoyance, it can cause serious problems in your home. When cold air sneaks through gaps, your heating system works overtime to maintain temperature, increasing your energy bills.

These unwanted gaps can lead to condensation forming around your door frame. Over time, this moisture can seep into walls and woodwork, potentially causing damp problems, mould growth, and even structural issues. During the colder months especially, fixing draughts becomes crucial for maintaining a warm, dry home.

Five Ways to Help Reduce a Draught

1. Adjusting the Hinges

The majority of the problem often lies with alignment of the door. Over time, regular use can cause door hinges to shift slightly. You should be able to remedy this issue yourself.

Start at the top of the hinge and work down. Depending on the type of hinges, you’ll need an Allen key or a screwdriver. Look at the side of the hinge, you should spot adjustment screws. These usually control up/down and in/out movement.

Make minor adjustments, turning the screws no more than a quarter turn at a time. After each adjustment, check the door’s movement and alignment. The key is to work slowly until you achieve the desired adjustment. You’re aiming for an even gap between the door and frame all the way around.

For older uPVC doors, you might find the fixings have become loose. In this case, tightening the screws at the centre of the hinge might solve the issue. Just be careful not to overtighten, as this can strip the screw holes.

2. Checking and Replacing Door Seals

The rubber seal around your door frame plays a significant role in stopping draughts. These seals can harden, crack, or compress over time, creating gaps where cold air enters. Here’s how to check and fix them.

Run your hand around the edge of the door when closed, feeling for cold spots. Inspect the seal’s condition and look for the following:

  • Cracks or splits
  • Areas where the seal has come loose
  • Compressed or flattened sections
  • Missing pieces

Replacing seals isn’t too tricky, but getting the right type is crucial. Your door manufacturer is normally able to help you supply the correct replacement. When fitting new seals:

  • Remove the old seal completely
  • Clean the channel thoroughly
  • Start fitting from the top
  • Don’t stretch the seal as you fit it

3. Adjusting the Locking Mechanism

A door that doesn’t sit properly against its seals when closed often means the locking mechanism needs adjustment. This is particularly common in older uPVC doors where regular use has caused misalignment.

Start by checking the keeps (the metal plates on the frame that the locks engage with.) These can often be adjusted to create better compression:

  • Loosen the fixing screws slightly
  • Adjust the keep position
  • Test the door’s closure
  • Tighten everything back up

If the door is hard to lock, don’t force it, as this suggests that the alignment needs work. Look for even gaps around the door when it’s closed.

4. Working with Compression Screws

Modern uPVC doors contain compression adjustment screws, which control how tightly your door sits against its seals. Located along the edge of the door frame, these screws need careful adjustment:

  • Identify all compression points
  • Make quarter-turn adjustments only
  • Check closure after each adjustment
  • Ensure the lock still engages smoothly

Too much compression can damage seals and make the door hard to close, while too little leads to draughts. Finding the right balance takes patience and gentle adjustment.

5. Installing a Draught Excluder

When other adjustments haven’t fully solved the problem, a draught excluder can provide that final barrier against cold air.

Different types available include:

  • Brush strips for minimal clearance gaps
  • Rubber seals for uneven floors
  • Drop-down automatic seals that lift when the door opens
  • External door brushes for added protection

When to Consider a New Door

Despite regular maintenance and adjustments, a replacement door sometimes becomes the most practical solution. Consider a new door if:

  • Adjustments no longer hold for long
  • The frame shows signs of warping or damage
  • You notice increasing energy bills despite fixes
  • The door has become difficult to lock securely
  • The door feels unstable when opening or closing
