All Marathon staff from first consultation to completion helpful, cheerful and professional. Work carried out on schedule and to agreed budget. Standard of work and quality of product excellent. Fitters very considerate and left everywhere clean and tidy. We were constantly kept informed at every stage. We would not hesitate to recommend this company.

Dealing with Marathon Windows was good from start to finish. Visits for assessment and measuring up were on time, friendly and polite; the fitters were friendly, polite and efficient and left everything clean and tidy. We are also very pleased with the quality of the new window.

I have had now all my windows and doors done by this company. From Tony who measured and to the fitters who installed them, it has been a 1st class experience. Very happy customer.

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.

Extremely pleased in all aspects from service to price to fitting and after care care service. We have ordered additional Windows to be fitted.

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.

Excellent experience especially with the whole COVID situation. From communication to installation it’s was a very pleasant experience and would highly recommend. Quality of workmanship, materials etc A1

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.
