Five years ago I had all my doors and windows, gutters, drainpipes etc replaced by Clarkes Windows, and they did a brilliant job. I have just had my conservatory replaced by them. Once again the process was simple and straightforward with advice given without pressure from knowledgeable and friendly staff. I ran an AI check on the quote and was told it was very reasonable given the quality of the materials. Given my previous experience I had no hesitation in placing an order. Tony Clarke came to do the survey and confirm final details with me. The deposit paid I awaited delivery. Four days were allowed for the build, but it was completed in three. The fitters were highly skilled and took every care to ensure the finished product was perfect. I cannot rate them highly enough, and as a bonus they were most friendly and helpful. Darren, the leader mentioned that I had raised an issue with a window with Mr Clarke and said he had been asked to deal with it. This had been just a throwaway remark! The service provided by this company is not only exceptional, it goes beyond what one could ever hope for. I did seek advice and quotes from three other companies, but for various reasons their ideas and products did not match Clarke's for practicality or quality. Two experiences, five years apart, different teams but the same exemplary service. Should the need arise in future, I will not seek other quotes but go straight to Clarkes.

I would highly recommend Clarkes. I had 7 replacement windows and a Composite front door installed. The initial visit was very informative and the price quoted was competitive. Everything was fully explained. The windows and door were ready earlier than expected which was great. The installation team arrived on time and completed it in 2 days. They did an excellent job, I am very pleased, it all looks great. Thank you.

Absolutely brilliant service from start to finish. Everyone from sales, to tradesmen to owner were all very professional and polite. Suffered a few delays due to the relentless rain but we were kept constantly appraised of the situation and everything humanly possible was done to try and make the most of any good weather opportunities. The workmanship was very good with a very high level of finish. I can't recommend Clarkes highly enough.

We decided to have new blinds in our patio doors so called Clarkes. Someone came out within a few days to measure up and give us a quote. After accepting the quote the new panels were fitted a few weeks later by the excellent fitters. They are a great company to deal with, nothing is too much trouble.

Clarkes were a pleasure to deal with. Two initial visits (one to quote and one to survey) then all our upstairs windows (5) replaced in a day and a bit. The fitters were polite, careful and considerate. The office kept in touch throughout, being careful to confirm with us so we always knew what was happening. The windows are excellent.

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.

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.

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.
