If you own a home, keeping an eye on the condition of your windows and front door is essential. This article explains the most obvious warning signs to watch for, helping you make informed decisions before small issues turn into bigger ones.

How do I know when to replace windows

• Your home suddenly feels colder, even when the heating is on

If one room feels chilly while another is warm, then that's not "just how older houses are". It's a sign that your frames aren't insulating properly anymore. Draughts often start gradually, so homeowners get used to them… until the heating bills start climbing.

• Condensation between panes

Condensation on the outside can be normal. However, condensation between the panes means that the sealed unit has failed and is no longer insulating your home. This commonly results in damp patches and a persistently cold feeling indoors.

• You can hear the street more than before

If everyday noise (cars, neighbours, early-morning birds) suddenly feels louder, chances are that your windows have lost their acoustic performance. Ageing frames and worn seals let far more sound through than they should.

• The frames look tired, warped or damaged

Peeling paint, rotting timber, cracked seals, or aluminium that has started to distort-all these things point toward one thing: your window frames aren't doing their job anymore. Structural wear reduces both comfort and energy efficiency.

• They no longer open or close the way they used to

If the sashes stick, scrape, drop or require extra force, the mechanisms are wearing out. A window that doesn't operate properly isn't just inconvenient – it may also be unsafe.

your front door needs replacing too

1. You can feel the draughts without opening the door
2. Cold air coming through the edges of a closed door is one of the clearest signs it's past its best. Worn seals, gaps in the frame or swelling from moisture all break the thermal barrier.
3. The door doesn't sit straight in the frame
4. If your door is starting to drop, scrape the floor or feel heavy to close, the structure is shifting. Over time, this only gets worse and can affect both insulation and safety.
5. Visible cracks, fading or swelling
6. Timber absorbs moisture, composite doors can fade from UV exposure and steel can eventually corrode. If your door looks like it has weathered one storm too many, replacement is the most effective solution.
7. Your home doesn't feel as secure as it should
8. Older doors often lack modern locking systems and reinforced cores. New composite and aluminium doors offer strong multi-point locking, better materials and improved resistance against break-ins.
9. It no longer suits the rest of your home
10. Ever updated your windows, refreshed the facade or given the entrance a new look, only to realise the front door no longer matches? A new, well-designed door can instantly bring the whole property together.

Local considerations

Kingston upon Thames has a unique mix of Victorian, Edwardian and mid-century houses, many of which still have original joinery. These older frames are rarely energy efficient and often struggle with moisture and fluctuating temperatures caused by proximity to the River Thames.

Choosing the right option for new windows and doors in Kingston

The most popular material for new windows Kingston is uPVC, thanks to its affordability and low maintenance. Aluminium, on the other hand, offers slim frames and a contemporary look, making it ideal for modern extensions and renovated period homes. Steel solutions are another increasingly popular choice, especially for those looking for a refined, minimalist or industrial-style finish with great durability.

For entrance doors, composite models provide outstanding insulation and security.

When comparing products, it's worth paying close attention to the U-value, which shows how well a window prevents heat from escaping. Lower numbers mean better insulation – and for most modern homes, a U-value around 0.8 W/m²K offers superior energy performance.
