Duration Windows Reviews 

Great variety of stock in showroom and very helpful and knowledgeable staff.
Duration staff Ken Dantes was very helpful, there was no hard selling, and all our (many) questions were answered professionally and with curtesy, as well as humour .
Despite asking for several quotes these all arrived within 48hrs and are very competitive.

Ken and all the duration team were amazing. Very helpful and great communication. I wouldn’t use anywhere else for our windows and doors.

So we are only at the quotation stage, build due to start end of may, but too date Ken and the staff have been extremely helpful and clear in there estimates.
Will be looking to place an order within the next 4 months

Really pleased with the doors we purchased over 10 years ago and when we recently had an issue with a door gasket a replacement was sorted very quickly - outstanding customer service from Lucy Bonham in the Aftersales Department. Would highly recommend.

We had a remote showroom viewing with Ken, looking at options for replacing our Crittall windows with aluminium look-alike heritage windows by Duration. Ken was extremely helpful and knowledgeable about his products and provided us with a quote within 24-hours.

I would rate Duration Windows very highly.
In fact we intend using them in another project very soon. .

Ken in the show room has been excellent, great knowledge and advice. highly recommend
Thanks Danny

Ken was very helpful right from the beginning. Everything I asked him for was executed within 24 hours to me great satisfaction. There s not really anything to add accept Thanks Ken!

From the moment we arrived at Duration Windows showroom and spoke to Sales Manager Ken, we have had an excellent and responsive service. Ken has guided us through each stage from showing us the range of products on offer and their relative costs and benefits (helping us make the most informed choices), to helping us communicate with other sections of the organisation in order to make 1)get our order sheet right 2)get the best deal 3) get the best timescales for delivery in relation to the other time pressures of our renovation. We are very glad and grateful for Ken’s support and Duration Windows services. We are returning customers and once again, Duration have not let us down. Thank you to Ken and Duration. We will be back again!

Ken was fantastic, helped answer all my questions, followed up with extra support when needed. Can't recommend highly enough

Amy was extremely helpful, and patient! Very knowledgeable and willing to help throughout the quotation process.

I have been using Duration Windows for many years and have always received excellent service. Their products are high quality, their customer support is outstanding, and even for large orders, I usually receive quotes within a day.

We recently completed a very large order of almost 100 windows, including secondary glazing, and the whole process was smooth and efficient. I’m extremely happy with the service—especially from Willow Griffiths, who is always fast to respond, helpful, and professional.

We’re very pleased to continue working with Duration Windows and would highly recommend them.

Visited showroom to look at all options and everything was explained very clearly by Ken
Very helpful team and efficient service.

Willow has helped me out with my order and it’s been incredibly smooth sailing.

Excellent service and quality product, highly recommend

It was really useful to meet with Ken and learn about the Duration Heritage windows. We have recently decided to go ahead with an order. Ken was very helpful and knowledgeable and it was great to be able to ask questions and get some ideas for our project.

I have a very old house that is listed with a complex requirement for a secondary glazing unit. Ken on the Sales team gave me prompt responses to all the questions that I had.

Duration Windows,
I wanted to take a moment to express my sincere appreciation for the excellent service I recently received from Ken at the Canvey branch for Duration Windows. From start to finish, Ken was professional, knowledgeable, and genuinely committed to ensuring I understood everything I needed to know, and more.

He took the time to understand my needs, provided clear and helpful advice. His friendly manner and attention to detail made the entire experience stress-free and enjoyable.

It’s rare to come across someone who combines expertise with such a personal touch, and Ken truly went above and beyond. Please pass on my thanks to him. His efforts have left a lasting positive impression, and I will gladly recommend Duration Windows to others. Ken is certainly an asset to your company.

PS. Thank you for the goodie bag, the tap measure will certainly come in handy.

Kind regards,
Stephen Buttifant.

We found Ken to be very helpful during the whole process when ordering our fantastic new windows, duration delivered on time as promised

I have been dealing with Duration for over a decade and am always impressed by both the business attitude of the sales and technical team, but also the quality of the products delivered... the bespoke nature you can achieve at trade pricing is priceless as a construction professional.
