Retrofit Double Glazing

Mike's Glass can retrofit the windows in your Wellington home with double glazing for a warmer, drier, more comfortable living space.

Maintain character

Add value to your home

Retrofitting double glazing is the process of replacing the current single-glazed glass in your windows with double-glazed, insulated glass systems. It lets the existing window structure and surrounding cladding remain in place, avoiding damage to them and retaining the original character of the home. Retrofit double glazing also adds value to your home, and is more cost-effective than brand new double-glazed windows.

With Mike’s Glass, you can choose from the best glazing products on the market for both wooden and aluminium frames, backed by a 10-year manufacturer’s warranty on the retrofit double-glazed units. You’ll also receive a lifetime warranty on our workmanship.

Where possible we do all the work on site, including removing the windows, rebating the frames and reinstalling the windows the same day.

We retrofit double glazing for residential and commercial customers in Wellington, Hutt Valley, Porirua and Kāpiti Coast. Call us now for an obligation-free quote.

Improve home insulation

Retrofit double glazing has many benefits

Double glazed windows help keep your home dry, warm and cosy during winter, cool in summer, and quieter all year round, with less street noise. Plus your energy bills will be lower.

0%

Reduced heat lost through your windows in winter by 50% compared to single glazing.

0%

Your house will be about 30% cooler in summer.

0%

Outside noise will be reduced by about 25%, making your home quieter.

Far less condensation

Condensation is dramatically reduced, and any issues with mould will most likely disappear.

Tailored glass and coatings

We can tailor your installation with special glass and coatings to improve specific areas of performance. These include preventing heat loss (argon gas), noise reduction, and UV blocking (low-E glass).

Skylights and glass roofs

We can also fit double glazing to skylights and glass roofs, such as those in conservatories.

'Pay by the room' double glazing offer

This allows us to complete the double glazing of your existing windows in stages, as and when you can afford it.

There is no need, or expectation, for all the work on your house to be completed at the same time in one job.

We can work at your home every few months or when you have the budget. We will start with south-facing windows, and continue from there at a pace that suits you.
