It started with the windows pre-sales assessment and recommendations. I was very grateful here as I received straightforward, honest advice about my options. I had three other companies come over, but the pre-sales received here was by far the best. The quote was the second best, but the assurances were there. It also helped that several of my neighbours had used the service. The survey was done on a Saturday which helped me a lot. (Pre-sales assessment also offered on a Saturday.) The fitters also came early and I could get to work on time and did a great job, leaving no mess. Throughout the service was quality, timely and competitive. No hesitations on recommending this company. :-)

This was the second time I had used Marathon Windows as I had been very pleased with the initial service. Second time around Marathon surpassed my expectations. I needed a quick job to replaced three windows.A competitive quote was arranged quickly followed by the survey and fitting followed within 3 weeks. I was kept well informed throughout of progress and at all stages Marathon came when they said they would and on time. Work was completed to a high standard and I was delighted with the final result. I have already recommended them to a neighbour. It was a pleasure to deal with a long standing local family business (in excess of 45 years) and will have no hesitation in using them again.

I have used Marathon over the last 30 years and find them to be reliable trustworthy professional and always go the extra mile for there customer can not recommend them enough a joy and satisfaction to deal with be it with Head Office all the team on site.

Good experience from start to installation. However, bad experience and poor communication when dealing with poor quality control on 3 double glazed units. After 2 visits in May and July, replacements still had scratches, each replacement was worse than previous one! October now and still waiting, this time for the manufacturer to come over and have a look at scratched glass panels. Also, black substance oozing out of sealant at corner of window frame. Wondering how much longer I need to wait for everything to get sorted.

We are very happy with our new windows. Fitters were hard working, polite, quiet and helpful regarding difficulties regarding our animals. Pleased with the look and quality of windows.

Well done you have a great team, providing refreshingly honest and up front customer service. The use of dedicated installation technicians, showed great professionalism, their attention to even the smallest of details meant the service was seamless. They did you proud. I am a big fan of shopping local, you all did a fabulous job. Thank you.

Just had a new front door fitted and we’re so happy with it. The service from start to finish was fantastic, helpful and professional. Great price as well ..... as I did shop around but decided to go local and I’m so glad I did. Happy to give them five stars and recommend to all my friends and family

After doing our due diligence and receiving several quotes we chose Marathon. We knew we had made the right choice when Tony who came to measure up repaired some damage to our front door on the spot after being asked if it could be repaired as part of the overall work. We had a patio door and kitchen windows fitted by Adam and Billy who were efficient and professional throughout. Very pleased with the finished product and have no hesitation in recommending the company and would use them again.

Marathon replaced all the original sash windows in our house with similar uPVC ones. We are delighted with the result and the service we have received. The saleswoman who first called, the surveyor who measured up and the men who installed the windows were all polite and helpful - and above all professional. We are so pleased we selected this company.
