"after sales service"

After more than ten years the gasket on our door needed replacing. Elise sorted this in a few emails. So easy.
Really pleased with the service. In addition our bi-fold doors have been trouble free for this time

"I have been dealing with duration…"

I have been dealing with duration windows for years they are without doubt the best company for your window door and roof lights.
The staff and aftersales are amazing nothing is too much trouble they get back to you immediately and are so helpful.
Lots of the windows doors and roof lights I have purchased are for coastal properties we have never had a problem with any of them.
Great company and products.

"Ken Dantes at Duration was so helpful and knowledgeable "

Ken Dantes at Duration was so helpful and knowledgeable. We have been looking to replace a large number of windows in our conservation area property, so the design and look have to match our original windows. Ken provided options and provided a detailed quote with price and specifications very quickly. We are waiting planning permission now, but have been really happy with Duration and most certainly recommend them. They make a great product.

"Great support in choosing the right product"

Our thanks to Ken Dantes Mortimer for his expert knowledge and understanding. After finding Duration online Ken showed us around the various options in the showroom. Lots of detailed information and off cut samples to take home. We then had further questions. Ken gave us an online tour around the showroom again and more samples sent through the post. His support led to us finally choosing this company to supply our secondary glazing.

"Excellent support from Jon Wade"

Job Wade helped me to choose the best secondary glazing for my Victorian house renovation. The showroom provided ample choice of style. It was Jon’s helpful and expert knowledge that gave me confidence in buying windows from Duration. He also gave excellent support and assistance in the specification and purchase of the windows. Many thanks

"Great you still around - fab advice from Daniel "

We bought bi-fold doors from you many years ago and have now just started researching for a new project. Was delighted to find you still at Canvey. Been in today and meet Daniel who was so helpful and gave us such good advice. We will for sure be ordering from you in due course.
