Brilliant after sales

Duration don't still make the 13 year old sliding doors that were damaged in an attempted break in, but they searched their warehose for the original profile, lock, etc. and made up a perfect replacement Fantastic after sales service; really going the extra mile, where replacing 3 doors and a frame would have been more profitable. Recommend these guys highly

Remote showroom viewing with Ken

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.

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!

We’re very pleased to continue working with Duration

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.
