Why Are My Windows Drafty? The Complete Guide You Need

Living with draughty windows and doors can be frustrating. You may notice curtains moving even when windows are shut or feel cold spots near seating areas.

If this sounds familiar, you’re not alone. Many UK homeowners deal with this issue. Understanding the causes of draughts and how to fix them can improve your comfort and reduce energy bills.

How Draughty Windows Affect Your Home

Draughty windows impact more than comfort. According to the Energy Saving Trust, up to 30% of your home’s heat escapes through inefficient windows. This leads to higher energy bills, costing the average UK household an extra £120-£160 per year. Beyond costs, draughts create cold, uncomfortable spaces and may contribute to damp and mould growth due to temperature fluctuations.

Why Windows Become Draughty

Worn Weatherstripping

Weatherstripping seals the gap between your window sash and frame, preventing air leaks. Over time, this material degrades, typically within 5-7 years, creating gaps where cold air enters. If your home has original windows from before 2000, the weatherstripping may need replacing.

Window Frame Issues

Window frames expand and contract due to temperature changes. This natural movement can cause cracks and gaps, particularly in wooden frames. Even modern uPVC frames can develop draughts if they weren’t installed correctly or have been exposed to extreme conditions.

Failed Double Glazing

The Energy Saving Trust reports that 24% of UK homes have failed double glazing seals. When seals break down, insulating gas escapes, reducing thermal efficiency. Signs of failure include foggy patches between glass panes and increased cold air near windows.

Poor Installation

Improper installation accounts for about 15% of window-related draughts. Installers may leave gaps around the frame or fail to use sufficient insulation. In some cases, windows may be slightly too small for the opening, leading to air leaks over time.

Identifying Draught Problems

A simple way to check for draughts is with a candle test. On a windy day, move a lit candle around the window frame. If the flame flickers or smoke drifts, you’ve found a draught point.

Another method is the paper test. Close a window on a piece of paper and try pulling it out. If it slides out easily, the seal isn’t secure.

Solutions for Draughty Windows

DIY Fixes

For minor draughts, replace weatherstripping or apply fresh sealant around frames. Draught excluders and secondary glazing film can also provide temporary relief.

Professional Repairs

If the problem is more severe, a professional assessment may be needed. Experts use thermal imaging to pinpoint heat loss areas and recommend cost-effective solutions. Options include resealing gaps, replacing failed double glazing units, or installing trickle vents for controlled airflow.

Long-Term Solutions

Upgrading to modern, energy-efficient windows can eliminate draughts permanently. Features like low-emissivity glass,multi-chambered frames, and improved seals enhance insulation. While new windows require upfront investment, they typically pay for themselves through energy savings in 8-12 years.

Regular maintenance can also prevent future draughts. Clean window tracks and frames every three months to remove debris that could damage seals. Reapply caulking every two years and check window locks and mechanisms to ensure a tight seal.

Can I fix draughty windows myself?
 Small draughts can be fixed with new weatherstripping or sealant. Structural problems or failed double glazing require professional repair.

Will draught-proofing reduce ventilation?
 Proper draught-proofing won’t affect planned ventilation. Modern solutions allow for airflow control while maintaining necessary air exchange.

How much can I save by fixing draughts?
 Fixing draughts can lower heating costs by 10-20%, depending on your home’s size, window condition, and chosen solution.
