Great Service

I bought all the windows and doors for my house 11 years ago. Inevitably some things break. Duration have provided superb ongoing customer care by providing spares for repairs at reasonable prices. Most recently Lucy Bonham has helped source new window hinges that had broken by a gust of wind.

Great ongoing service is the mark of a quality company. I unreservedly recommend Duration. They are great people to do business with. ⭐️

white gaskets

I asked about white gaskets & was originally told these were not possible on 1000 slimline. But Willow Griffiths did not take that as gospel and so pursued this on my behalf, only to find that you can in fact have white internal gaskets, which with an all white bifold makes sense. So thank you for going the extra mile on behalf of the customer.

Showroom visit

Visited the showroom today and was so impressed with not only the products but the time that Ken spent with us explaining every question we asked in details. Without doubt the 5*s are partly due to Ken's enthusiasm and expertise. It gives me trust in Duration's products and service.

Fantastic customer service

We bought 2x flat flush skylight windows 2 years ago, we're very satisfied with the price and quality but unfortunately a few months ago I realised the glass had blown in both of them, I contacted customer support and Lucy was fantastic, very helpfully aided me to upload photos of the windows and our access arrangements and arrange for ck reactors to come and replace the glazing units less than 3 weeks later. FANTASTIC CUSTOMER SERVICE!

Very Happy Customers

We made an appointment and drove a two hour journey to visit the showroom in the summer to look at the various types of bifolds and windows. We met Ken who was extremely knowledgeable and helpful in all matters. We were overwhelmed by so many choices to consider. At the time we didn't have our extension dimensions but chose the Emperor Concealed bifolds design type and tilt and turn window. Ordering and payment was made simple by the knowledge and assistance of Willow & Courtney, thank you. Delivery was also great and the driver contacted me within an hour of delivering so I could contact my builder to offload, as agreed.
We are very happy with the products and can't wait for our extension to be completed in a couple of weeks time to really enjoy the products to their full potential and great design. Would happily recommend Duration Windows

Thank you to Jon

My partner and I are really grateful to Jon who has been super friendly, knowledgeable, and helpful when it comes when it comes to us choosing our doors and windows. We came into the shop and he answered all of our questions (given we have limited knowledge on what is required etc.) and was giving really good advice. On top of that, he even gave us a free gift bag, which was such a thoughtful surprise and the items are super useful. Including a water bottle, tape measure etc.

His service made the whole visit so much better and pleasant. If you’re looking for a place with great products and even better people, I highly recommend stopping by. Huge thanks to him for helping us out.

Duration bifolds - very high quality

Duration bifolds are very high quality. Delivery is great and after-sales service top-class

Also, I needed 3m tall doors and they were only company I found who could do these.

Good job duration.

I've used Duration for years, and i don't frankly think I'd go anywhere else for my aluminium.

Customer service is always 10/10.

I regularly chat with Lucy B, and always know that if i have an issue, it will get sorted. Thanks Lucy!

Very helpful to visit...go in person if you can to see the options

We made an appointment and met with Ken in September who walked us through all the sliding door options available for our conversion, listened to our specific needs and advised accordingly. We're glad that we made a visit in person rather than leave the decision to our builder as we were able to get what we actually want... we almost certainly would have ended up with the wrong style for us had we not. Doors have been ordered and we are hoping to have them installed soon. Can't speak to the delivery but meeting with Ken was extremely helpful.

Amazing customer experience

I spoke to Vicky to organise some replacements gaskets for my alu french doors. She couldn't have been any more helpful or pleasant to deal with. Or efficient; the parts arrived the very next day, delivered to my door by Duration. Fantastic service and Vicky is outstanding at her job and deserves a rise - or at minimum some flowers and chocolates (hopefully her Boss is reading this.... )

Our initial encounter with Duration…

Our initial encounter with Duration windows, allowed my wife and I to be ourselves and we quickly realised that having a disability was not seen by this organisation as a hindrance.

The staff member made every effort to speak to my wife who uses a wheelchair, her mannerisms reassured both of us that she genuinely wanted to help.
This level of attenivness to our needs continued throughout each department, even when communicating became an issue their professionalism and concerns were paramount regarding our wellbeing.

Our builder even commented that he found the organisation very helpful when he asked for further information.
We will complete our findings when we take delivery of our skylights. Thank you Duration Windows. (Emma and Charlie)
