Why draughts matter

Even small gaps in frames can have a large effect on household energy use. Instead of keeping warmth in, leaks pull heat out, forcing boilers and heaters to work harder. By taking simple steps such as draught proofing doors or sealing faulty frames, households can save money while improving comfort. Installing or upgrading to energy efficiency windows also brings long-term benefits.

Signs your windows and doors need attention

Cold air around frames

If you feel a noticeable chill when standing by a window or door, it’s time to fix draughty windows or reseal doors.

Light showing through

Gaps that let light through also let heat out. This is a clear indicator that sealing has failed.

Stiff or loose closures

Frames that no longer close smoothly can leave gaps that worsen draughts.

Condensation or frost

Cold air seeping in cools surfaces, often leading to moisture or frost on the inside edges.

Practical fixes you can try

Weatherstripping and seals

Replacing worn strips is one of the most cost-effective ways to stop air leaks.

Door sealing tips

Letterbox covers, brush strips, and under-door draught excluders can cut down on unwanted airflow.

Secondary glazing

An extra pane on existing windows helps reduce draughts in older properties without full replacement.

Adjustments

Hinges or locks that have slipped out of alignment can usually be reset, helping frames close more tightly.

Temporary draught-proofing

Self-adhesive tape is useful for a short-term fix, especially in winter months, though it should not replace permanent solutions.

When professional help is best

DIY options go a long way, but professional advice is worth seeking when:

  • Frames are warped or damaged
  • Repeated attempts to fix draughty windows fail
  • You need guidance on upgrading to energy efficiency windows
  • Seals and glazing have failed completely

Contractors can provide targeted window repair advice, install proper draught proofing doors, and recommend whether replacement or secondary glazing is the better choice.

Local support

For homeowners in the Cotswolds, in areas like Clevedon, Long Ashton, Nailsea, Portishead, and Weston-super-Mare, one option for wider property services is Prestige Cleaning Cotswolds. While their core focus is on cleaning (carpets, upholstery, ovens and more), companies like this often work alongside trusted local trades and can point households towards reliable help for door and window repair, draught proofing, or energy efficiency upgrades.

Keeping draughts away long-term

  • Inspect seals annually and replace if worn
  • Keep hinges and locks maintained
  • Avoid overpainting frames, which can damage seals
  • Ventilate properly to reduce condensation and frame movement

Fixing draughty windows and draught proofing doors not only saves on heating costs but also improves comfort and sustainability at home. Whether you try DIY methods or call in professionals, the key is to act before minor leaks become major problems.
