Excellent new windows

After a couple of our neighbours had used Derwent Windows we decided to contact them and enquire what they could do for us. What an excellent experience from start to finish. Not just the range of window options, but the attention to detail, the communication process and of course the fitting of the windows. One particular point to note was the quality of the window fitters. They were an excellent bunch of guys. If anyone asks about our windows we have no hesitation in recommending Derwent Windows.

Had a new front door and 3 windows installed in 2019 which we were really pleased with. Had a new utility door installed this year and again really pleased with the process throughout - everyone was friendly, and professional. Great service and the door is looking great.

Built a Bentley

Well, what a joy, what an experience, what a result. 'Period Orangery' built in 3 months to a high specification with large sash cord windows and lantern with tumbled facing bricks from north cot brick with fabulous Aluco doors linking to the main lounge. Derwent during the build period never missed a beat and their quiet focus on the quality of work and detail was ever-present. Beyond being built to architectural with this level of focus I was very proud to be part of the team. Anticipating a Jaguar, we have built a Bentley.

We have recently had a brand new front door and stained glass top light fitted at our new house and we are delighted with the quality and look of the product and fitting. The communication after visiting the showroom was good and whenever I needed to call for an update and I could get straight through and speak to the person handling our order. We had a little hiccup along the way with some of the glass being damaged during removal however I cannot fault the service provided in response to this to get it resolved and we have ended up with an even better toplight as a result. Everyone we dealt with was professional and friendly the fitters workmanship is top quality. Overall, we are delighted with the door and service provided. I would 100% recommend.

In my experience Derwent Windows appear to be a well managed company whose service is of a high quality at all levels through the whole workforce. From assessment to completion of the work they give attention to detail and always put the customer first. Yes they are more expensive than other companies offering window replacement but my belief is that it is well worth the extra expense to deal with a company that operate with integrity and employ a skilled and trained workforce. I recommend them without hesitancy.

Derwent replaced 16 of our Sash and casement windows on our Victorian house. From start to finish they have been very easy to work with and are the opposite of a hard sales window company. There work is second to none and we are really pleased with the windows we have had so many compliments already. They aren’t the cheapest on the market however they are worth every penny to know we have had the best job done. Would highly recommend and will be using them again when we have our extension.

Derwent Windows provided the best customer service we have ever experienced. They were extremely helpful, very professional and the standard of work from the fitters was outstanding. Whilst the windows are not the cheapest, the quality is high and we would definitely choose them again.
