Bay of Plenty
Ryan Double Glazing has been retrofitting aluminium windows and doors across the Bay of Plenty and Waikato since 1994.
Retrofit Double Glazing Bay of Plenty
The Bay of Plenty is one of New Zealand's most desirable regions to call home — great climate, stunning coastline and a strong sense of community. But even in the BOP, homes get cold in winter, condensation builds up on windows, and energy bills climb higher than they should.
Ryan Double Glazing has been helping Bay of Plenty homeowners improve their homes for over 30 years. We specialise in retrofitting double glazing into existing aluminium windows and doors — no full replacement, no council consents, no fuss.
Serving the Wider Bay of Plenty Region
Our double glazing specialists work across the Bay of Plenty region, including Tauranga, Mount Maunganui, Papamoa, Waihi Beach, Ōpotīki, Rotorua and surrounding areas. Whether you're in a classic coastal home or a newer rural build, we'll assess your joinery and recommend the right solution for your situation.
Why Retrofit Double Glazing?
Retrofitting is significantly cheaper than replacing your windows entirely. We simply swap out your existing single panes for sealed double glazed units — the process is tidy, quick and causes minimal disruption to your household. Most jobs are completed within a single day.
The results speak for themselves: warmer rooms, less condensation, reduced outside noise and lower heating costs. It's one of the best investments you can make in a Bay of Plenty home.
