Winter Window Problems: What to Look Out For

Winter can be tough on your home — especially your windows. As temperatures drop and wind, rain, and frost set in, small issues can quickly turn into bigger problems. Spotting early warning signs helps you stay warm, reduce energy bills, and avoid costly repairs.

Here’s what to look out for this winter and how to decide whether you need a repair or full replacement.

1. Condensation Between Glass Panes

Some condensation on the inside of windows during winter is normal. However, condensation trapped between the panes of double glazing is not.

This usually means the sealed unit has failed. When the seal breaks, moisture enters the space between the panes. Over time, this reduces insulation performance and causes fogging that won’t wipe away.

What to do:

• If condensation is inside the room, improve ventilation first.

• If condensation sits between the panes, the sealed unit likely needs replacing.

In many cases, you can replace the glass unit without replacing the entire frame.

2. Cold Draughts Around the Frame

If you feel cold air near your windows, even when they’re closed, you may have worn seals or gaps around the frame.

Draughts increase heating costs and make rooms uncomfortable. Older uPVC or timber frames are particularly prone to this issue.

What to do:

• Check for cracked or flattened rubber seals.

• Inspect frame edges for visible gaps.

• Consider resealing or upgrading older windows.

If your windows are over 15–20 years old, a full replacement may be more cost-effective long term.

3. Failed Window Seals

Winter weather causes materials to expand and contract. Over time, this can weaken window seals. Failed seals allow moisture, cold air, and even noise into your home.

Signs of seal failure include:

• Whistling sounds in strong winds

• Visible cracking in rubber gaskets

• Increased condensation

Replacing seals can sometimes fix the issue. However, if the frame has warped or deteriorated, replacement may be the better option.

4. Sticking or Hard-to-Open Windows

Cold weather can cause window mechanisms to stiffen. Moisture and dirt can also build up inside locking systems.

If your windows:

• Stick when opening

• Don’t close smoothly

• Feel tight when locking

The hinges or locking mechanisms may need adjustment or lubrication.

When it’s a repair:

Minor stiffness usually requires simple maintenance.

When it’s a replacement:

If the frame is warped or the locking system is damaged beyond repair, upgrading to modern windows improves both function and security.

5. Increased Heating Bills

If your heating bills suddenly rise during winter, your windows could be part of the problem.

Older glazing allows heat to escape. Modern double and triple glazing significantly reduce heat loss and improve energy efficiency.

Upgrading to energy-efficient windows:

• Keeps warmth inside

• Reduces draughts

• Lowers monthly bills

• Improves your home’s EPC rating

Repair or Replace: How to Decide

Here’s a simple guide:

Choose Repair If:

• The frames are in good condition

• Only seals or hinges need replacing

• The glass unit has failed but the frame remains sound

Choose Replacement If:

• The frames are warped or damaged

• Multiple issues are present

• Windows are over 20 years old

• You want better insulation and security

Modern uPVC and aluminium windows offer stronger security, improved insulation, and a fresh look for your home.
