Is It Time for New Windows? The 3-Minute Homeowner’s Guide

Many homeowners treat windows and doors as "lifetime" features, but they actually have a functional expiry date. When your windows hit the 15-to-20-year mark, they often transition from being a protective barrier to a household liability.

Ageing windows don't just kill your kerb appeal—they skyrocket your energy bills and pose genuine safety risks. If you’re tired of feeling a breeze through a closed window or mopping up sills after a downpour, use our Four-Step Assessment to decide if it’s time for an upgrade.

The 4-Step Checklist: Should They Stay or Should They Go?

01. Know the Lifespan Baseline

While high-quality systems are built for durability, standard windows have a limited design life. If your home is over a decade old, or if you live in a coastal or harsh environment, your windows may be nearing the end of their effectiveness.

02. Spot the Material Warning Signs

Inspect your frames and glass for these "red flags":

• Structural Wear: Warped profiles, peeling coatings, or visible cracking.

• Seal Failure: Weatherstripping that feels brittle, lacks "spring," or is falling out.

• Hardware Issues: Rusted hinges, sticking locks, or handles that feel loose and shaky.

• The "Must-Change" Signal: If you see fog or moisture between the glass panes, the internal seal has perished. This means your insulation and noise-reduction properties are officially gone.

03. Evaluate Your Daily Comfort

Performance failure isn't always visible. If you experience any of the following, your windows are no longer doing their job:

• The Draught Factor: Feeling cold air near the window or struggling to maintain indoor temperatures.

• Moisture Intrusion: Water leaking onto the sill or damp, mouldy patches on the surrounding walls.

• Noise Pollution: If street noise is just as loud inside as it is outside, your acoustic seals have deteriorated.

04. Choose a Solution That Lasts

If your windows check two or more of the boxes above, a full replacement is more cost-effective than constant, temporary repairs. To ensure your next set lasts, look for premium specifications:

• Primary Aluminium: For superior structural integrity.

• PA66 Thermal Breaks: To effectively block heat and cold transfer.

• EPDM Gaskets: For a long-lasting, automotive-grade seal.
