Most double glazing fails because it’s measured from rough plans, installed by subcontractors, and fitted with generic frames that don’t quite seal. Even a few millimetres of gap can let heat, cold, and noise straight through — ruining the benefits you paid for.
On top of that, many systems are built for European climates, not WA’s harsh conditions. That’s why so many homeowners spend thousands, only to feel little difference.
We don't quote off plans or rough dimensions. We physically inspect and measure every opening in your home to ensure a tight, insulated fit - so you get maximum comfort and real energy savings from day one.
Most companies offer just 5 years. We back every install for a full decade - if anything goes wrong, we'll fix it free. No stress, no delays, no charge.
