Marathon Windows provided a fantastic service from start to finish. Tony, Jane, the office team and the fitters are very professional, helpful and really friendly. It is rare to find a company who are reliable, trustworthy and punctual, Marathon Windows are all of these. They did a great job and I will definitely be using them in the future and recommending them to family & friends.

Replacement windows for my flat
Customer Service

From the start of the process to the finish every single element was carried out accurately, professionally and sensitively. From Jane and Tony carrying out the initial visits for measurements etc through to the guys who carried out the work, every single person was efficient, organised, accurate, friendly and sensitive to my concerns as someone at high risk and anxious about mask wearing etc. To make the job easier for the guys I went and sat in the garden so that they wouldn't need to wear their masks while working indoors, and when I tried to persuade them to pause for a tea break, they said they just wanted to crack on so that I had my home finished and secure as quickly as possible. They didn't take any breaks at all and when they finished, the clean-up was so perfect I didn't need to do a thing and you wouldn't have known they'd been there except that I now had these perfect windows! I actually stand and admire them, and my neighbours have been full of compliments. The price was reasonable and the work impeccable, and I wouldn't hesitate to recommend them.

Replacement Double Doors - third Installation by Marathon

After the successful installation of new front and side doors in 2020 we decided to complete the the final part of our plan to secure the property by asking Marathon to quote for replacing ageing double doors leading to our patio. As before the work was carried out efficiently both on time and budget with all members of the installation team polite and considerate. In the next couple of years we intend to replace all our windows and would have no hesitation in contacting Marathon once more to complete the work.

This is the second time Marathon Windows has completed work for us. This time they renewed our front door and replaced 3 windows within our house. As expected the work was completed without any problems and to a high standard. I would not hesitate in having them back again for any work of this type.

Fitted outside door and fitted trim to loft windows

Marathon Windows fitted an outside door for us which had been previously fitted by a builder only a few months before. Their work was first class, Les who came out to do the job was very polite, respectful of our property unlike the previous builders, tidy and kept me informed throughout. Also fitted trim to loft window. I have recently had them round to quote for trims to remaining windows and replace a seal in the bathroom. Highly recommend. Use with confidence nothing seems to be too much trouble for them.

I cant recommend this company enough. Everyone we met from the company was friendly, knowledgeable and super helpful, and the team that fitted the windows were effecient, polite and tidy. They made good the rendering on the walls after fitting the windows and door and when i called because i noticed the letterbox was slightly crooked it was dealt with pretty much immediately with someone coming back to straighten it the following morning. Everything happened when they said it would without any need for chasing and unlike other suppliers they didn't ask for a 50% deposit. In fact, their costs and payment terms were the best of the 3 quotes we received. Im so pleased we chose Marathon and would highly recommend them.

Good experience. No hard sell or silly pricing "offers". Kept all appointments, and kept to the timetable for installation that you first gave us. The large window you fitted for us is looking good.

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.
