Do You Recognise These Common Window & Door Issues?

Cold Draughts

Even when the heating is on, you feel a chill indoors? Draughty windows let in cold air, making your home less comfortable and your energy bills higher.

High Energy Bils

Old or poorly sealed windows allow heat to escape, causing your boiler to work overtime — and your energy costs to soar every winter.

Condensation & Moisture

Do your window panes mist up? Condensation between the glass layers or on the inside of your windows is a sign of failing seals and poor insulation.

Outdated Appearance

Faded, discoloured, or mismatched frames can drag down the look — and value — of your home. It’s not just cosmetic; it reflects ageing materials that may be failing.

Stuck or Hard-to-Open Windows

Struggling to open or close your windows? This can be a sign of warped frames or mechanical failure — and a potential safety issue.

Outside Noise

Thin or single-glazed windows do little to block out traffic or street noise. Upgrading can restore the peace and quiet inside your home.
