We were given a recommendation for Marathon Windows, Jane was absolutely lovely who came to measure up, they provided a fair quote really quickly and throughout the order process she really took time to make sure everything was perfect. The fitters work tidy and they were delivered within the correct timescales and the new windows look absolutely fabulous. WOULD HIGHLY RECOMMEND THEM.

A new window was installed which has transformed the room. The work was carried as planned in a very profession, considerate manner. Once complete the team cleared the site both inside and out to a high standard. We are extremely pleased with the finished effect and wished we had spoken to Marathon Windows years ago.

We have used Marathon Windows four times in the last eight years. In all they have supplied us with 13 double-glazed windows, a new front door, a replacement for our ageing French windows and a bi-fold door for our newly-refurbished kitchen. They don't use the gimmicks that other companies use (e.g. inflating the price then offering huge discounts). Their sales staff are helpful and honest with you. Their products are excellent and reliable. I would have no hesitation in recommending Marathon to my family, friends or colleagues.

Fitted windows and doors throughout our house. Fantastic service; worked quickly and efficiently and tidied up well. Reasonable price and finished ahead of schedule. Would highly recommend.

I would highly recommend Marathon Windows. A very friendly and professional company which is happy to work in tandem with their client. The builders and fitters are very hard working, a pleasure to have around and take care to tidy up at the end of the day. There is a great team spirit and I would certainly use them again.

Marathon did a fantastic job for me, replacing a new but badly designed and installed bay window which had been put in only a few weeks before, by the builders working on my garage conversion. So pleased I made the decision to get this work redone by a professional company. The new window is well fitted and the design is good, and meets my specification. Both Tony and James were extremely helpful in supporting me to make various informed decisions, without me feeling pressurised at all. Stan the installer was also very knowledgeable about his job and paid great attention in order to get every aspect of the installation correct. I thoroughly recommend.

Great service provided by all members of the team. Was kept informed at every stage of the process of assessment, ordering and installation of window. Have purchased windows and door from the company and would not hesitate to recommend them. I will be ordering further door and windows to complete the renovation of our flat. All staff very helpful, knowledgeable and professional at all times.
