High Performance Double Glazing 

Nicky Sevier, Christchurch

On the 19th January your team of extremely competent young men arrived to install our retrofit . double glazing after patiently waiting while we struggled with health issues which we greatly appreciated. They showed such care to the install and worked so well as a team.
They were very efficient, caring and respectful and the end result is we have a wonderful warm cosy house which is so quiet we can't even hear the dogs barking next door. It is absolutely fabulous. One very large window which we had been told could not be double glazed was fitted by your boys seamlessly and it was exciting to see it going in. We would highly recommend Comfortglaze for any of your window needs, they are an extremely competent, friendly and wonderful company to deal with.

Our Process

FAQ's

Do you retrofit both aluminium and timber windows in Christchurch?

Yes. We retrofit double glazing into existing aluminium and timber frames throughout Christchurch and surrounding suburbs.

How long does installation usually take?

Most Christchurch homes with aluminium frames  are completed within one to two days, depending on size and scope. Timber windows take a bit longer, more like three to five days. 

Will double glazing help with condensation and cold winters in Christchurch?

Yes. Double glazing significantly reduces condensation and heat loss, improving comfort during colder Canterbury winters.

Do you remove windows overnight?

No. All work is completed on site, and windows are never left unfinished overnight.

Can you modernise older aluminium joinery?

Yes. We can remove colonial bars, redundant mullions, and unused doors while upgrading to high-performance double glazing.

How much does retrofit double glazing cost in Christchurch?

Retrofitting existing frames is considerably more affordable than replacing full window units. Pricing depends on window size, quantity, and glass performance, and we provide clear, obligation-free quotes for Christchurch homes.
