No work is unimportant to us, therefore we are happy to give a no obligation quotation for any size job, be it a single window, a whole house of windows or a conservatory.

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 job was scheduled 2 weeks earlier than expected. The guys were prompt on arrival, fast & efficient. I was appraised at all times about any potential issues & possible solutions. They worked quickly & efficiently, were very friendly & cleared up well at the end of the day.

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.
