Choosing a Competent Window Installer
Given New Zealand’s aging housing stock, the ongoing maintenance of our homes is becoming more challenging, especially when combined with the constant changes in our building regulation. Whether retro-fitting new glazing, updating to insert window frames, or completely replacing the existing joinery with new, these tasks are rare in the life of a building never mind that of a homeowner.
Around two-thirds of our homes were built last century, before much of our current Building Code requirements were introduced, including the use of high performance frames and double glazing.
What are the rules and regulations? Do I need consent? What level of replacement am I looking at? Are all questions among the myriad that homeowners are suddenly having to navigate – areas beyond their everyday knowledge base. All of which can be tricky, because when the time finally comes, you’re expected to compare quotes, understand glazing standards, and make decisions about installation methods — despite never having thought about any of those things before.
Not every window installer and/or glazier operates to the same professional standards. And when it comes to windows and doors, issues from poor quality installs don’t always present themselves straight away. They might appear later as leaks, drafts, condensation, or the creeping realisation that something isn’t quite right.
Unfortunately, insufficient communication and that knowledge gap is exactly where problems can begin.
The good news? The Association has a series of online guides to assist you through the process, but these few simple checks can dramatically reduce the risk.
Why choosing the right window and installer matters
Windows and doors do more than just let light in, provide access, and help to ventilate your spaces. They play an important role in your home’s:
• energy efficiency
• weather-tightness
• safety
• overall comfort throughout the year
Selecting the right frame and glazing combination is important to the ongoing function and comfort of your home, but selecting the right installer is vital to your home’s longevity. Mistakes made here will impact your home for life, regardless of the product choice!
What does a competent window installer look like?
A competent installer is someone who offers glazing or window installation services that follow recognised industry standards.
They will:
• assess your home and provide advice on the replacement that best suits your needs and budget
• offer a competitive quote, but include explanations around areas of uncertainty
• provide surety around the timing of the installation
• use compliant products selected for your situation and budget
• communicate exactly what is involved in the job
• provide sound after sales service to ensure you are happy with your new windows and/or glazing
Communication is a vital part of the project from both parties’ perspective. Our series of online guides includes checklists so you know which questions to ask of your installer/glazier and allow you to assess their competence for yourself.
Warning signs to watch out for
If you’re speaking with a window installer, keep an eye out for a few potential red flags.
1. The quote seems too good to be true
2. There’s no written quote or contract
3. You’re asked for a large upfront payment
4. There’s little evidence of previous work
5. Compliance isn’t discussed
6. They avoid responding clearly to questions regarding their work, processes, and/or warranties
A simpler way to reduce risk
One of the easiest ways to protect yourself is to work with businesses that belong to recognised industry bodies like the Window & Glass Association.
Members commit to maintaining high professional standards and ethical business practices across manufacturing, supply, and installation.
In other words, they’ve agreed to operate under a framework designed to protect both the industry and the homeowner.
Questions worth asking before you hire
Before committing to a window installer, it’s worth asking a few simple questions:
• Is your offering the best option for my home?
• What standards does this installation comply with?
• What products are being used?
• What warranties apply to the work?
• Can I see examples of previous projects?
• Are you a member of the Window & Glass Association?
A professional installer won’t hesitate to answer these.
Choose with confidence
Replacing windows is an investment in your home’s comfort, safety and long-term value. Taking a little time to check credentials and understand who you’re working with can make a big difference to the outcome. And when you see the Window & Glass Association member badge, you know you’re dealing with professionals committed to doing the job properly.
Which, when it comes to something that should last decades, is exactly what homeowners deserve.
