This is the second time I have used CLARKES Windows and I can’t speak highly enough of everyone down to the person on the end of the phone. The contractors are so very pleasant and complete the job, and clean up after themselves, you wouldn’t know you had anything done! I would recommend them every time to my friends, and keeping it local is the key!

I would really reccomend Clarkes windows with no hesitation. Right from the start to completion went extremely smooth, just how things ought to be. The Lads that came where, pleasent, polite and easy to chat to, busy working and made sure we where happy. They where so tidy and also new how a henry hoover worked ! Luckily for us they had completed their previous job earlier than expected so came and fitted the second window so 2 teams got the jobs done twice as quick. Bonus all round. A real credit to the company they all where. Both my husband and i are very pleased with how well the whole process went and of course the end result.

Excellent service from start to finish. Very helpful lady in the showroom who explained all the ( many) options and organised a home survey. And excellent installers ( thank you Gary and John) who did a very good job including finishing all the seals and cleaning up. We are very pleased with the results. Delivery of the door was on time and we were telephoned as soon as it was available and we chose the best installation date for us. Thank you

From the outset we were very impressed by the efficiency of the staff at Clarke's. The survey and quote process was quick, helpful and very clear and the price was highly competitive. The manufacturing was completed within a few weeks and an installation date agreed. The installation itself was conducted by friendly fitters whose work was beyond reproach creating immaculate, undetectable joins with the existing structures and leaving the work area clean and tidy. The windows and doors themselves appear to be high quality and are certainly as good as well known brands we have used previously. Subsequent minor queries, arising largely from my own misunderstandings, were handled cheerfully and helpfully by the friendly office staff. A thoroughly pleasing experience and we are delighted to be able to both recommend highly and thank the Calrke's Windows team.

I was extremely impressed by the two young men who fitted 3 new windows for me. Aston and Luke were personable, polite, tidy, discrete, good humoured and extremely efficient. Thank you! I very much hope that when Clarkes fit my upstairs windows next year, this Double Glazing Duo will be the team that I can welcome back! Prior to the fitting, the surveyor, Chris, was also extremely professional and very congruent and helpful in his comments. There was no hard sell, merely sound and practical advice. The staff in the office have also been prompt to answer the phone and to help me with any enquiries. I would strongly recommend this company.

The fitters for our windows were very professional and friendly. They worked quickly and well and have done a splendid job. We are very pleased with the windows and were able to feel the benefit or the extra insulation of the double glazing straight away. We would thoroughly recommend this company in terms of both their service and the product supplied.

From our visit to the showroom to having the French doors fitted in the kitchen, Clarke’s Windows have provided excellent service. All the staff have been professional, friendly and helpful. The men who came to do the fitting were very good and the whole process took less than half a day. I would have no hesitation in using Clarke’s again and would certainly recommend them.

I needed two exterior doors replaced and contacted Clarkes Windows as I have used them before. They again proved very easy to deal with and carried out the work in an efficient and friendly manner. From choosing the doors in their showroom to the fitting was only a few weeks and the end result is exactly what I was looking for.

A great experience from start to finish, price may not be the cheapest, but the quality of material and workmanship was first class. Work was whole house doors and windows, from the day we made the order to the completion has been a breeze, windows and doors really good quality and fit great. Full marks to the fitters who were professional, courteous and ensured we were happy every step of the way. A minor snag at the end was sorted quickly and efficiently. We would have no hesitation in using Clarkes again and would thoroughly recommend them.

I neglected to do this earlier, and I apologise.

All at a very reasonable price. I would not hesitate to give this lovely family-run firm the highest reference.

Replacement windows
I have used Clarkes many times over the last couple of years to install new windows (and one door) and on each occasion I have been very pleased with their work. Their installation team are always very efficient, and very tidy when they perform the work. They may not be the cheapest but their standards are consistently good. I would have no hesitation in recommending this company.

Clarke's came to us through a friend's recommendation. They visited us to discuss the job and provide an estimate and also gave us advice on options. Having accepted the offer they came again to confirm measurements and talk us through the job. As agreed the delivery date came in the expected timescale and the installation date was agreed.The installation team arrived on the agreed date and talked us through what was going to happen with the removal and the install of the windows and doors. All we can say is professional professional professional. The careful removal and attention to detail on the new install has left us with a great new product in our bedroom and you wouldn't have known any one had been.We will be asking them back to look at replacement options for the rest of the house. Says it all.

Replacement of aluminium tilt turn window
Customer Service
Quality

At the quotation visit, I showed Tony the original paper work provided by the original suppliers, outlining thicknes etc. I also explained that the external glass was in fact 2 panes sort of fused together, then a gap and a further pane on the internal side. I was surprised when he said the whole frame/window would be removed (a previous fitter said the casing was fine) When I recieved my quote for a new window, it did not explain things clearly, I had to ask what the thickness of the glass would be. After checking with Clarkes windows regarding the glass, I assumed I was going to get like for like. Unfortunately the make up of the new window is completely different, It consists of 3 individual panes of glass, with a gap between each pane, which has resulted in the recess being too narrow to accommodate my £140.0 "perfect fit clip in blind" to be re-fitted. Also the operation of the window is more complicated, even the fitters found the restriction bar difficult to operate and were going to mention it to feed back to the suppliers. Living by a railway line, the noise reduction is not as efficient as the old window As the window has settled, cracks in the plaster around the new frame have appeared. For me personally the replacement window has been an expensive disappointment and I hope others will be made more aware of what/how their replacement window is constructed.

The trader replied (on 02/10/2025)
Thank you for your feedback. We would like to clarify a few points regarding your review. Firstly, this is the second review you have posted regarding the same order, with the first submitted on 26/06/2025. The work was completed on 20/06/2025, not 23/06/2025 as stated in this most recent review. Posting multiple reviews on the same issue, particularly with differing details, can be misleading and does not reflect the full context of the situation. As discussed with you at the time of the initial survey and documented, we explained that there was no guarantee your original clip-on blinds would be compatible with the new window frames. Despite this, our team made multiple visits to try and assist with fitting them, but unfortunately, it was not possible due to the change in frame design. We always encourage customers to contact us directly with any concerns so we can resolve matters promptly and fairly. We are disappointed that this was not your chosen course of action before posting these reviews, as we are always happy to help where we can. Should you wish to discuss this further, please feel free to get in contact with us directly.

We had our 3 front original sash windows replaced with PVC replicas. The initial visit and quote we received were timely and gave options for our budget. The fitters were on time, polite, and professional. They covered all the areas they had to work in or walk through, including stairs. They showed the opening and locking mechanism once fitted. There was good communication throughout from the office. A professional and friendly service. Thank you.

I chose Clarks Windows after recommendations from previous customers. Having seven windows and a front door replaced they were completed in the time frame and dates given. The two fitters Jake and Lewis were very polite and considerate throughout their work. After each session they would clean up and vacuum. The workmanship of the fitting was excellent and the quality of the units fitted were superb. Communications from the Office were quickly sent and helpful. Thanks to all at Clarks Windows for a great job and service.

Ok, so a stone flicked out of the mower and broke Mother's double-glazed window. Loss of brownie points. Called Clarkes, and their guy came out to measure up. Anyway, a few days later, two guys showed up and in under ten minutes, the window was replaced, brownie points restored. Mother was very impressed with the speed and efficiency of your polite installers. A credit to your company. No mess, no fuss. Thank you, Clarkes. Awesome.
