Marathon installed 6 wooden sash windows for me. There is a long lead in from ordering to installation, but that's because the windows have to be specially made to order from another manufacturer, so I was expecting that. The guys that came to install them were really good, the installation went smoothly and when they did encounter problems they solved them - the windowsill outside on the bay window was rotten and fell apart when they took the old windows out so they made a new sill in hardwood and fitted it beautifully and then got a painter in to paint the sill and some other areas. All in all very pleased.

We have no hesitation in recommending Marathon Windows. This is the fourth time we’ve used them as we have moved house. They come down to West Sussex and have fitted all new windows and doors for us. The service from Tony when measuring is excellent and the fitters are all cheerful and friendly. No mess left in the house at the end and all windows work perfectly.

Replacement front of house windows - Amazing job

My husband installed our front windows some 40+ years ago and it was time for them to be replaced. We were recommended Marathon Windows (a family run business) by a neighbour. Mum (Jane) came to quote, Dad (Tony) came to survey & measure and, within 6 weeks, Son (Luke) came to install. We were informed that the upstairs front windows would be replaced on the first day and the downstairs the second day and that’s exactly what happened. Luke, Jack and Les were so professional: punctual arrival time - with only a short break for lunch - respectful use of dust sheets and, at all times, polite and cheerful. Our windows now look spectacular and the boys left everything neat and tidy – both inside and outside. It honestly looked like no-one had been in the house at all! You could see they took great pride in their work – and it showed. Incredible service from start to finish, we cannot fault them at all. Without hesitation, we highly recommend this wonderful family business.

From start to finish our experience with Marathon Windows was nothing but positive. We had a problem with existing bay window which was diagnosed by the surveyor. A new bay was fitted by their expert workmen who were friendly and proficient - and left no mess. We also had a beautiful new front door fitted with the same proficiency. We considered the price of both window and door to be extremely fair and the experience was completely stressless. We have no hesitation in recommending Marathon Windows and will certainly use them again.

Marathon windows from start to finish, were helpful, friendly and efficient. Jane visited my house on the 9th July to discuss my requirements. Jane offered very practical and helpful advice. I received a quote by e mail on the same day. My quote was competitively priced. I was given a timescale of work, and Jane was always available to speak to with any queries. The work was completed ahead of the timeframe and I am absolutely delighted with my new windows and doors. A big shout out to Paul and Anthony who completed the work, they were friendly, polite and informative. All work was completed to a high standard and my home was left very clean. I would definitely recommend Marathon windows.

I was very pleased with the attitude and performance of the company from asking for a quotation to the completion of the installation. They kept to the date given for installation. The installers were both excellent. They took their time to provide an expert installation of the bay windows in the children’s bedroom. They cleaned the room after install and took all the rubbish away.

I am delighted with the work carried out by Marathon. My sash window has been replaced by a door, giving me direct access into our communal gardens and a lot more light. I'm already making friends with the foxes! The fitters were a great couple of lads; always on time, hard working, polite and scrupulously clean. From the initial visit, the follow up to take measurements and then the installation, everything went without a hitch. I would have no hesitation in recommending Marathon, a thoroughly professional outfit.

Marathon were called in for a quotation to replace a rotting back door, complete with new frame and sill.. The work proceeded a few weeks after acceptance and was carried out by Adam and Anthony who did a splendid job which met all my expectations. Everything was left very clean and tidy.
