Why Windows and Doors Get Worse Over Winter (And What to Do About It)

Many homeowners notice that their windows and doors seem to perform worse after winter. Handles feel stiffer, draughts appear where there were none before, and doors may become harder to close or lock. This is not a coincidence.

Cold weather, temperature changes, and increased use all place extra strain on windows and doors. At MK Doors & Windows, we regularly help homeowners across Milton Keynes resolve issues that develop or worsen over winter.

How Winter Affects Windows and Doors

Temperature changes cause movement

Materials such as uPVC, aluminium, and composite expand and contract with temperature changes. Repeated freezing and thawing can cause small shifts that affect alignment and sealing.

Increased use during colder months

Windows and doors are opened and closed more frequently in winter for ventilation while heating is running. This added use increases wear on hinges, locks, and seals.

Cold weather hardens seals

Rubber seals become firmer in cold temperatures. Over time, this can reduce how well they compress, leading to draughts and heat loss.

Moisture and condensation

Higher indoor humidity during winter can expose weaknesses in sealing and glazing, making problems more noticeable.

Common Post-Winter Problems

• Draughts around window and door frames.

• Windows that rattle or feel loose in windy weather.

• Doors that rub, catch, or require extra force to close.

• Locks that feel stiff or misaligned.

• Increased condensation or misted double glazing.

What Can Be Done to Fix These Issues?

Servicing and adjustment

Many winter-related issues are caused by minor misalignment. Adjusting hinges, locking points, and keeps can restore smooth operation.

These issues are commonly resolved through our Window and Door Repairs service.

Seal replacement

If seals have hardened or deteriorated, replacing them can significantly reduce draughts and improve insulation.

Sealed unit replacement

If winter has highlighted misted or failed glazing, replacing the sealed unit can restore thermal performance without changing the frame.

More details are available on our Sealed Unit Replacements page.

Secondary glazing for older properties

For older homes or properties where window replacement is not suitable, secondary glazing adds an extra internal layer of insulation and can reduce winter-related issues.

You can find out more on our Secondary Glazing page.

Is It Better to Fix Issues Before Spring?

Yes. Addressing problems before spring helps ensure windows and doors perform properly throughout the year. It also prevents minor issues from developing into more costly repairs.

Late winter is an ideal time to service and repair windows and doors while issues are still easy to identify.
