Duration Windows Anmeldelser 

We had a last minute requirement for some additional materials, Coral went out of her way to ensure the extra we needed was added to the delivery for the next day (I have no doubt having to be very nice to several different departments to help us out). Excellent service, many thanks Coral

We moved into our new house 4 years ago, the windows having been fitted by Duration in 2011. Inevitably these have begun to fog up in places and Duration have been excellent in replacing what is needed.
Customer service (from Elise and Lucy) has always been helpful and generally extremely efficient, including finding the original orders and specifications from 14 years ago!. They provide excellent value for money, which includes delivery to our home. Takes about 10 minutes to replace.
Good company to do business with.

I have used Duration for around 6 years now. Their product quality is second to none.

The customer service is impeccable. Always timely, efficient and most helpful.

Ask for Willow and you won't go wrong! From pricing to final confirmations and aftercare - I'm yet to experience such good quality customer service. Thank you Willow & Duration!!

I was referred to Duration as I was advised they were professional and well priced and they certainly were, Ken Mortimer the Sales Manager was extremely helpful, he communicated everything quickly and the lead times are excellent, defiantly will be my preferred window company for all our developments.

Fantastic company to deal with.
Their lead times are brilliant. We always say 'if Duration don't make it, nobody makes it'.
Always helpful if we have any questions.

Lucy Bonham was great however the dispatch team failed on 2 occasions to send replacement door seals for faulty units.
We have 2 sets of triple bifold doors which look great however in 3.5 yrs we have had to replace seals on 3 occasions. The original seals are light grey & Duration now advise they are unable to source this colour & can only supply black ! Whilst it is better than nothing it looks very much out of place. The 10 year warranty may still be in place however it is extremely poor that Duration cannot supply light grey seals as per the original supply.
Lets see how the doors perform for the balance of the warranty 6.5 yrs however looking at the durability & replacement of seals to date it would look to be unfortunately an ongoing problem so its something to take into consideration when looking at purchasing from Duration

We visited the show room in Essex. Good range of sliding patio doors. Daniel is very professional and knowledgeable about the products, and the visit was very informative. We left understanding a lot more about all the options and their implications.

Lucy was really good, found exactly what I needed and sorted it for me ASAP.

Really been a great three years plus now living with fab bi fold doors and dorma windows! From the get go the company was recommended by a respected builder he was not wrong! The lead time was exactly as promised, the doors and windows both excellent in quality and price. Delivery was efficient and Corteous, a small issue dealt with under warranty has been expertly and detailed by Lucy who has top class, regular updates by emails and issue resolved
Thank you team Duration and well done

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.

Very helpful staff helped me out with a problem and rushed a job through
Thanks ken
Many Thanks

Just been into the duration windows showroom,
good range of products and really well talked through by Ken . As developers we found it all very useful and look to place an order this week.

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!

Thank you Daniel for your help and advice today - it was invaluable! We are looking forward to seeing our Duration windows and doors complete our home :)

Ken gave us a very thorough virtual presentation of Duration's offerings. He demonstrated the operation of each of their products and patiently answered all our questions.
We were very impressed!

Had a really positive experience of the aftersales support. We had our bifolds installed in 2016. Elise went above and beyond to help locate our order number and provide replacement parts for our door handle. Thank you !

I am coming back to Duration for the second time now, having received excellent service from Ken and been impressed with the quality and durability of the windows.

Ken Mortimer has helped technical and design aspects and is very knowledgeable and helpful.

Solid company, great 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.

As always Duration Windows comes through
I needed some specification information for an EPC advisor on an installation I phone reception Coral said she would find the information all I had was a postcode and approximate date of installation, within minutes the email with what I needed was in my inbox.
Thanks

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.
