Window Installation FAQs

How long does a typical window installation take?

Most standard window installations take 1-2 days, depending on the number and complexity of windows. A typical house with 8-10 windows can usually be completed in a single day by our professional installation teams.

What preparation is needed before window installation?

We recommend removing curtains, blinds, and clearing furniture from around the windows. Our team will protect your floors and furnishings with dust sheets, but accessibility to the windows helps ensure a faster installation.

Are your window installations energy efficient?

Absolutely. We specialize in energy-efficient window installations using the latest thermal technology. Our windows meet and often exceed current building regulations for thermal performance, helping to reduce your energy bills.
