FAQs

How long does it take to install windows and doors?

This often depends on the condition of the site and how complicated it might be. Usually, a two-man team of fitters will complete three to six windows per day.

Why is this?

This only happens if your room or house is badly ventilated. When purchasing your new windows from us, we can insert trickle vents, which can be opened or closed to ensure your room is ventilated properly. It is not healthy to have unventilated rooms. Our vents also have insect screens to ensure no bugs or insects can join you in the night.

Can you supply windows for use in UK conservation areas?

We can supply windows suitable for conservation areas across Greater London. It is essential that you check with your Local Authority regarding the status of your property in terms of conservation. Sadly, we are unable to enquire on your behalf.

How competitive are your window prices compared to others?

All of our prices are highly competitive due to our unique buying power. As we supply and fit 30-40 windows per week, we can bulk-buy your windows and pass the savings onto you.

Can you provide an estimate over the phone or by email?

We are happy to give you a quote via fax, email or in person. We can also send one of our surveyors to your home to measure up and discuss your needs and options. If you can supply digital photographs of the existing windows, we can provide our best price based on these photographs alone. This is what we need from you in order to complete a quote:
