A stress free experience. Marathon were very professional, efficient and competitively priced. I felt comfortable while the work was carried out, an important factor for an elderly lady, living alone. I highly recommend Marathon.

We had a superb experience with Marathon Windows for a new stable door. Jane and Tony were always in constant contact with regular updates and the entire experience felt tailored just for us. The final door installation was excellent and it looks fantastic. I would recommend them to anyone looking for windows or doors to a high standard.

Marathon have been reliable and efficient from planning to installation. Communication was good. They replaced 4 window panels also resealing window frames where needed, several heavily used window handles, serviced patio doors and replaced the front door. The chaps doing the work where polite, efficient and competent. The windows look new again and the front door looks fantastic and has given the house a face lift, apart from being a pleasure to use ! Marathon fitted our windows originally 25 years ago.

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
