First class service with excellent products

Excellent company and recommend for windows, bi-fold doors and french doors. After a substantial house fire, I had to replace most of the windows and doors in a house in Leigh on Sea.
I visited their showroom on about 4 different times as kept changing my mind.
Ken was super helpful and very patient and professional on all the changes and options and always made himself available on the day to deal with the order.
Chris also gave excellent advice from his wealth of experience.
Really nice people to deal with.
First class service with excellent products.

We had just purchased our new house by the sea in time for the summer and found some difficulty in closing our Duration bi-fold doors. One phone call catalysed their scheduling a date for a service call, and they then managed to expedite the date even sooner. The professional engineers attended to the problem swiftly and efficiently with no fuss. I was effectively a replacement purchaser of the doors and the warranty service provided was immediate, excellent and with no sniff of a quibble. They seem a very decent firm!

Awesome Service

had a fantastic experience with Duration Windows from start to finish. Their team was incredibly helpful and knowledgeable, guiding me through the best options for my project. The quality of the aluminium windows and sliding doors exceeded my expectations — sleek, modern design with excellent thermal performance.

Delivery was on time, everything was well-packaged, and installation went smoothly thanks to the clear instructions and support. You can tell they’ve been in the business a long time — professional, efficient, and reliable.

Showroom visit with Daniel

We booked our visit to the showroom and met Daniel. Great experience with him who walked us through the various sliding door and bifold door styles and the various options we can choose from for our renovation project. He was able to explain clearly the differences between the styles, door types and available colours. He was very helpful in all the queries we had and understood the importance to provide various quotation combinations.

Daniel was fabulous!

Excellent experience with Daniel who walked us through choosing 6m of sliding doors for our rear extension renovation! He was able to explain so clearly the differences between the styles, find something to fit our budget, and help us keep the kids entertained whilst we considered our options all with a big smile and super friendly demeanour! Thank you from Sophie and Kevin

We made an appointment to go to the showroom to look at a lean to roof and French doors for an extension we are adding to our house. We were greeted by Daniel who was very helpful and knowledgeable. He showed us the products we were interested in, and talked us through various options. Daniel was also able to recommend a fitter. There was no pushy sales pitch, or a sales pitch at all actually, which we really appreciated - just help and advice. We were so impressed with the products on offer and the quality is fantastic. Looking forward to fitting a new roof and door soon!

Above and beyond

I just wanted to extend my sincere thanks to your team, especially to Elise for outstanding service I received recently.

Elise went above and beyond to help organise a replacement window at incredibly short notice. Her professionalism, efficiency, and willingness to help made a stressful situation so much easier, and I’m truly grateful for her support.

It’s rare to come across such dedicated and responsive customer service, and it certainly hasn’t gone unnoticed.

Thank you again to Elise and everyone involved, I’ll have no hesitation in recommending Duration Windows in the future.
