Aluminium Bi-folding Doors

Installation Options

Supply Only

The majority of our customers are trade customers who only require us to manufacture and supply our bi-folding doors. In this instance we would supply you with bi-folding doors that have been manufactured to your exact specifications and fully tested at our factory. We would guarantee the doors, but you will take full responsibility for providing correct sizes and then installing your bifold doors. You can have your doors delivered, or collect from our factory.

Please be aware that the sizes we require are the overall sizes of the doors, and not the sizes of the hole you are installing them into. You will need to allow for fitting tolerances and also take the threshold, projection cill, floor levels and head extension for trickle vents into consideration.

Supply & Fix - by Duration

Installing bi-folding doors requires specialised care and attention. If you are a trade company or individual that doesn’t want the hassle of installing bi-folding doors, then why not get us to supply, deliver and ‘fix’ your bi-fold doors into an existing and fully prepared aperture. When ‘fixing’ our doors we will install the doors with due care and attention, toe and heel the panels, foam the frame, fully test the doors, and leave the doors in a perfect working condition. Our fixing service is normally available within 150 miles of Canvey Island.

Please note that our ‘fixing’ service is only available for our bi-folding doors and is by no means a full installation service. This service does not include (but not limited to) mastic, sealing outside, plastering, rendering, making water tight, removing existing doors or preparing the hole. This service was introduced in the interest of helping our trade customers, so that they can save time, avoid all of the aggravation associated with the fitting of bifold doors, while not losing or avoiding jobs that include bifold doors. We will come out to site and survey the prepared aperture, take responsibility for the manufacturing sizes and the fixing of the doors within the hole. We will guarantee our workmanship and the doors.

Please make sure all involved parties; builders, homeowner and other trades are aware of what work is and is not done by Duration Windows. Please contact the Bifold door area of our Sales Department for more information.

Supply & Fit - by a Duration Trade Customer

In this instance we will provide you with the details of an experienced Duration Trade customer. You will deal directly them with them and they look after the whole project from start to finish. They will handle all aspects of the installation including survey, fitting, sealing and guarantees. They also usually take care of any building work, plastering and rendering etc. In the unlikely event of any problems you would deal directly with them. Not all trade customers offer building works such as RSJ's, please contact our Sales Department and make them aware of your exact requirements.

Onsite Instruction Service (your builders will be required onsite)

Bi-folding doors are becoming more and more popular thanks to homebuilding and renovating television programs. If you want to win more business by offering our popular folding doors to your customers, but you are unsure what you are getting yourself into, then we can help. New customers can take advantage of our onsite instruction service where one of our experienced bi-folding door installers will come out to site to assist you in fitting your first set of bifold doors. When you are done will also issue you with a certificate to show that you have gone through the initial training program for fitting our folding sliding doors.

Becoming A Recommended Installer

Once we consider you to be an experienced installer of our bi-folds we can refer customers, in your area to you. We receive countless numbers of leads phoning us, asking for supply & fit for our bi-folding doors. As a manufacturer we will pass these leads onto you. We can also provide you with samples for your showroom. If you lack room to get a bi-fold in your showroom, bring customers to see them at our exhibition centre on Canvey Island. You can show them around yourself or ask us to do it on your behalf, but please let us know when we should expect one of your customers.
