A first class product supplied and fitted by a first class company. Having used Derwent Windows previously we decided to approach the company to supply and fit the remaining windows in our property. Expert advice during the survey was given on the most appropriate type of windows. In this instance traditional casement rather than sash windows, two of which we had previously fitted by the company. Work was completed to the agreed schedule and budget despite some inclement weather conditions at times. The fitters were always considerate when in our home protecting fixtures and fittings at all times. Having used the company before we have found the aftercare excellent. We would have no hesitation in recommending Derwent Windows and will be using the company for future work.

Derwent Windows are usually very good, but with this order of just one window its been an awful experience. It was weeks for someone to actually visit and measure up the opening, which has had knock on problems meaning we weren't able to complete the extension weather proofing before Christmas. The chap fitting the window didn't seem to want to be here, and we still haven't got the keys to operate it. We placed an order with someone else for a Bifold door, and from order to fitting was 3 weeks.

As a family-run business, servicing the East Midlands for over 25 years, I take negative reviews very seriously as we strive for continual improvement and excellence. I have thoroughly investigated the facts of your order and offer the following observations and comments that I hope will offer a more balanced view. You have placed 5 orders with us over the last 7 years. You have stated that it took “weeks” for somebody to visit you for the survey. You placed an order with us on Wednesday the 31st of October 2023 for one window and we visited to carry out the site survey on Wednesday the 8th of November. 5 working days later. We emailed your contract and request for a deposit on Monday the 13th of November. You paid your deposit on the 23rd of November. You didn't approve your drawings or confirm your contract until the 30th of November, a delay of 13 working days. From approval of your contract to installation took 21 working days, taking into account the Christmas shutdown period. We took delivery of your window from the manufacturer on the 15th of January. We installed your window on the 16th of January. I personally called you on the 15th of January to ask if it would be a problem if we delayed your installation by a few days due to staff sickness. You advised me it wouldn’t be a problem, but I heard your wife in the background angrily swear. I have never heard such a reaction when asking to potentially delay the installation of an order. I then advised that the installation would take place on the agreed date of the 16th of January. The fitter arrived at 7.45 am and left approximately 3 hours later. After the installation, as we do with all orders, out of courtesy we phoned to ask if everything was ok with the installation. You replied that you were happy but there was a key missing for the window lock. We sent out a replacement key, but unfortunately, we sent out the wrong key. Out of all the complex orders we have ever processed, it seems very strange that an order for one window, installed into a new build extension, we have received our worst rating ever on which trusted trader. Especially when I look at the facts that from approval of the contract to installation took 21 working days. We are committed to your guarantee of 10 years and if you have any further problems, I am happy for you to deal with me directly. Kind regards Alister Walters

Decided to replace 2 doors and 2 windows including our front door..Viewed the products at a local showroom and obviously they were of very good quality.The surveyor was very experienced and was able to answer all our enquiries.Long lead time for manufacture but we were very pleased with the quality once fitted.The fitters were excellent working hard throughout the day despite heavy rain even refitting Venetian blinds afterwards which we thought we would have to do. Although they inadvertently cut through a telephone cable which both we and they thought was redundant when it turned out it wasn’t they successfully repaired the severance. Overall very happy with the product and extremely happy with the fitting.

This company has now undertaken installations at both my current and previous properties, in all, several stunning window and door projects over the past 10 + years. The work just completed (December 2023) required feasibility advice on the installation of brand new floor-to-ceiling timber windows in alcoves to either side of a fireplace. From the initial survey and valued technical advice, to ordering the bespoke timber products, and finally the skilled building work undertaken by the superb in-house team, everything went to plan - and looks fantastic.

We had two traditional casement windows fitted to the front of our house to replace existing windows, which were pretty much beyond repair. From start to finish the service we received was excellent. Options and costings were explained clearly and communication along the way couldn’t have been better. Very satisfied. Good company to deal with and would use them again.

Derwent windows initially installed 2 new French doors for us in April and we were so pleased with them that we went ahead and asked them to replace all the windows in our house which were in a sorry state. We were rather anxious as it was such a big, expensive job but we couldn't be happier with the finished result as our new windows are not only beautiful in appearance but they have made the house much more soundproof, warmer and secure. The whole job was completed within the 2 week schedule and the timekeeping of the window team was excellent. They were friendly, respectful and professional throughout and there was minimal disruption during the job. It has been a pleasure to deal with a company who not only have first rate products but also have a good team of window fitters to install them. Our thanks to the Managing Director Rob and all his team on a first class installation.

We live in a conservation area, so planning permission was needed. Derwent Windows we’re helpful and knowledgeable about the whole process. From our first showroom visit to installation we found all staff professional. All deadlines were met, the installation went smoothly with care taken working around garden plants and tidying after. We are very pleased with the finished job, the sash windows look fabulous and no painting! We will use Derwent Windows again and would not hesitate to recommend the company.

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.

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.

Replacement of Sash Windows
Customer Service
Quality

Derwent Windows gave an excellent service from the quotation assessment to the detailed site survey and then to the installation. I thought the nature of the site survey was particularly useful; we discussed the nuances of the installation and they were able to answer all of my queries in a detailed yet easy-to-understand manner. Therefore, I was very confident in the installation ahead, which mostly, I would not be at home to witness. The quality of the work carried out was very good. The sash windows provided are of excellent quality and the wooden architrave and facias (made on-site, at my home) that surround the internal of each window fit perfectly between the window and the wall. The slightly high price of the installation was largely driven by the need for quality sash windows that are in keeping with the age of my house and the conservation area in which I live. Informal quotes from other companies using the same type of manufactured sash windows gave a similar ball-park price. I was very pleased with the service provided by Derwent Windows and would recommend them to future potential customers.

We had a solid wood sash window replaced by Derwent Windows. The quality of the product is top rate & the fitters did an excellent job, very thorough, polite & exceptionally well cleaned during & at the end of the job. The time from order placed to fitting was very considerable , but that is the same very where I imagine. They are not the cheapest windows on the market, but I would rather pay a premium for the product quality & craftmanship. I would definitely use again & would recommend Derwent Windows

Old Toll House restored to original appearance

Derwent Windows were able to provide arched timber windows entirely in keeping with our early 19th Century Old Toll House. The transformation to our house has been amazing. So many neighbours have commented positively on the appearance of these windows including some older people who remember what this house used to look like. Comments like ' your new windows look stunning' have frequently been made. We are delighted with the difference these windows have made to our home - not only in appearance but also in better heat and sound insulation. The team did an excellent job and were a pleasure to work with. Follow-up after sales was also very good. There is no doubt that this project was expensive but we were prepared to pay for quality and see it as an investment in our property. But mainly we see it as a great improvement to our home on the edge of the beautiful Peak District.

So glad I made the journey to Ripley to see Derwent Windows. Had planned to used an installer locally but none of them return my call after quote stage. Derwent were brilliant from the moment I rang them. Arrange a time to visit their showroom and even what bus to catch to their showroom. A survey was done within a week of the visit. Their knowledge and customer care was so good, I put an order in straight away. The actually installation went smoothly. The fitter was great - explain everything that was going to happen and was so meticulous in the installation and tidied up afterwards. I am thrilled with my door. Wish I chosen them from the beginning. Thank you to all the team for their help!!!
