Clear Signs Your Glass Needs Replacing
Old or damaged glass might seem like a minor issue—but left unchecked, it can lead to safety hazards, higher energy bills, and even devalue your home. In this blog, we break down five common signs that it’s time to consider glass replacement, and how Canterbury Glass can help you make the smart choice.
1. Foggy Double Glazing or Condensation
Noticing a hazy look or moisture build-up inside your double-glazed windows? That’s a sign the seal between the panes has failed. When this happens, the insulating gas escapes and is replaced by moisture-laden air—making your windows less effective and your home less energy efficient.
This is especially common in Christchurch homes that face extreme temperature fluctuations or have older glazing systems.
What to do: We can replace the affected glass units without changing the whole window frame, saving you time and money. You’ll instantly notice the difference in clarity, warmth, and comfort.
2. Cracked, Chipped, or Scratched Glass
A small chip might seem harmless—but even minor damage weakens the glass structure and can quickly spread into a dangerous crack, especially in high-traffic areas or exposed locations like ranch sliders and front doors.
Scratches, while less dangerous, can still impact the look and feel of your space—especially in mirrors or glass features.
Why it matters: Cracked or chipped glass can become a safety hazard and reduce your home’s value. We provide fast, affordable replacements using toughened safety glass that meets NZ standards.
3. Cold Drafts or Poor Insulation Near Windows
A small chip might seem harmless—but even minor damage weakens the glass structure and can quickly spread into a dangerous crack, especially in high-traffic areas or exposed locations like ranch sliders and front doors.
Scratches, while less dangerous, can still impact the look and feel of your space—especially in mirrors or glass features.
Our solution: We can install modern, thermally efficient glazing options that regulate indoor temperature and improve energy efficiency—without compromising on style.
4. Glass That Doesn’t Meet Modern Safety Standards
A small chip might seem harmless—but even minor damage weakens the glass structure and can quickly spread into a dangerous crack, especially in high-traffic areas or exposed locations like ranch sliders and front doors.
Scratches, while less dangerous, can still impact the look and feel of your space—especially in mirrors or glass features.
We’ve got you covered: Canterbury Glass supplies and installs toughened or laminated safety glass to ensure full compliance with NZ safety standards. We’ll assess your home and recommend upgrades where needed.
5. Outdated, Worn, or Unsightly Glass Features
Sometimes, it’s not about cracks or drafts—it’s about aesthetics. Old, discoloured splashbacks, fogged mirrors, or dated shower screens can make your home look tired and unloved. Replacing these features with modern, frameless or coloured glass is one of the easiest ways to refresh your interior.
Think mirrored walls for added depth, coloured splashbacks for a kitchen statement, or a frameless glass shower to open up your bathroom space.
Let’s upgrade: We offer custom-cut, made-to-measure glass for mirrors, showers, splashbacks, balustrades, and more. Every piece is installed with precision and care by our local team.
