Replaced all windows at the front of our house
Have dealt with Marathon Windows before, very efficient and friendly. We placed our order with them and the end of June and they came and fitted 9th September. Fitters go out of their way to do a professional job, and leave everywhere tidy. Very courteous, and the office staff are always very good at answer any queries and responding promptly. The windows have made a great improvement to our house.

From contact to first visit, second visit to measure up, the fitting of all the house windows, patio doors, new fantastic front door and new back door with a cat flap fitted was excellent. All the staff, owners, office staff, fitters were all professional. No fuss no mess gave a choice of payments. I was recommended to use Marathon Windows and would definitely recommend them myself.

This company were very professional, didn't keep pestering us with phone calls like other local companies, they did the work ( front & back door & new smaller window in the kitchen, the outside wall had to be rendered & new wooden windowsill) one man did the whole job in 2days, tidied up, polite & helpful, would definitely have them again.

Timeless Leaded Windows

We have used Marathon a few times now (back double glazed then Garden room sliders). This latest job was for the front and side leaded windows which required a style sympathetic to the 1930’s character. We chose their ‘Timeless’ range. The team handled my queries promptly and the fitters were very professional. We are very pleased with the result, quality and price. Will use again when the Kitchen extension is complete for bi-folds.

Marathon Windows did a complete replacement of all of our windows (17 windows) and doors (3 doors). We are very pleased with the finished result. The installation was done over 5 days. The installation team were very professional and considerate as they worked around us. The installation was done to a very high standard with no damage to our internal decoration. Everything was left clean and tidy at the end of each day.

New front door

Overall my experience with Marathon was excellent. I felt like I was dealing with a small enough team of people who knew about my job, and was not dealing with a large company who were not aware of me when I rang. I found the office team to be helpful and approachable. Luke and Jack did a great job with the fitting of my new front door; they were very helpful, polite and professional, taking the time to do the job properly rather than getting it done as quickly as possible and leaving. I have used Marathon previously and will definitely use them again. The only negative I would mention is that it took a lot longer for the door to arrive than I had initially been advised and it would have been good to have received a call informing me of the longer than usual wait. However, it well worth the wait as the front door looks so smart and I have had several very good comments from neighbours and family.

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.
