Marathon have done several jobs for me - replacement patio doors, new door, front windows and now the back windows. Their service is excellent from initial contact, through estimating, surveying and installation. The price is extremely competitive, the products good quality and the installers are reliable, tidy, efficient and true professionals. I can highly recommend them.

Marathon are the sort of company you want to have to do your windows. We first used them 10 years ago to replace the windows in the front of the house, on the recommendation of a friend in Epsom. We’ve just had them redo the windows at the back and replace the front porch. They’re just as good now. All done in four days, rooms much brighter and lighter and no maintenance. They say they get their business by word of mouth, and I’m sure they do. I just told my daughter to use them for her new house in Reigate. The alternative are the big national companies who charge much more, you get all the high pressure selling and they’re only as good as the people who do it, who can be anyone. With Marathon you know who you’re dealing with.

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.

Not great when dealing with poor quality control

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.

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.
