Speaking to a member of the team couldn’t be easier. You can either fill out our simple contact form, call us on 01622 631613, or visit one of our two double glazing show centres in Dartford and Maidstone. We’ll be able to answer any questions you may have about your home improvements.

Receive your free quote

We’ll provide you with your individual quote within 24 hours of you contacting us or after a home visit. All of our quotes are free and no-obligation.

Place your order

We’ll confirm the exact design with you, including the glazing, decorative features, and hardware. Our administration team will provide your contract to one of our surveyors once your order has been placed and authorised. (2-3 days)

Signing Deposit paperwork.

Order deposit is requested

If we haven’t yet received your order deposit, we will request this. (1-2 days from paperwork being returned)

Arrange a surveyor visit

A date will be confirmed that is convenient for both parties for the surveyor to visit your home. This is to confirm exact measurements and review the size of the project, enabling us to give you a more accurate expectation of timelines. This is because if planning permission is required or you live in a conservation area, we’ll need to gain approval for your home improvements. (1-2 days)

Surveyor’s assessment is confirmed

You’ll be updated when the surveyor returns their assessment back to us. This states the size of the installation and any queries or regulations that are needed in order to complete your installation. (2 days if no queries, 1 week max if queries. Any protracted query delays, you will be informed)

Confirm an installation date

A member of our installation department will get in contact with you to arrange the installation date for your new windows and/or doors. (3-4 days unless there are delays)

Products ordered

Your windows and doors will be manufactured

Your new windows and doors will be constructed to your individual specifications at a state-of-the-art double glazing factory. The fabricators are highly experienced, using pioneering techniques and modern materials, for the best quality possible.

Installation day

Our professional fitters will arrive at your property at the agreed time. With a wealth of installations behind them, they’ll ensure the day goes smoothly with minimal disruption. They’ll also be able to advise the functionality and security of your new windows and doors and provide tips on how to keep them looking as good as new over their lifetime.

Remedial work addressed

In a minority of cases, remedial work may be required for your new windows and/or doors due to unforeseen difficulties. In this unlikely event, we will order any required parts and arrange a date for the work to be finished. (On receipt of parts or 1-2 days if no parts needed).
