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.

Marathon Windows replaced all our double glazing and front and back doors. From the beginning to the end, it was a pleasure to use Marathon Windows. Jane, who came to do our quote, was terrific — giving us great advice and suggestions. She was genuinely interested in providing what was best for us, not just making a sale. The installation team (Adam and Anthony) were friendly, efficient, and very tidy. Our new doors and windows are all of excellent quality and look wonderful. Couldn't be happier or recommend them more highly. Thanks again, Which for another fabulous company.

We are really pleased with our whole house window replacement from quotation through to completion. Such a neat job. Dust sheets everywhere. Cleaned up afterwards. No making good needed on inside and minor painting over small areas of render on outside will be needed. Also done in good time. Compliments to your installation team, Luke, Jack, Les and Adam. Would have no hesitation in recommending Marathon to anyone.

They installed windows on my period property look fabulous & in keeping with its character. I am very pleased with the service, quality, finish & price and would definitely recommend Marathon to anyone thinking of having new windows installed. Their after-sales service is very good too. I chose Marathon as they were recommended to me by a couple of friends who had work done on their properties and I am so glad I did. The owners are charming & friendly and were a pleasure to work with.

Throughout the whole process of replacing our windows and French doors - from estimating to installation - we have been very impressed by Marathon. Jane visited to advise and measure for the estimate and was really helpful. Anthony handled the installation work and took a real pride in his work. We are delighted with our new windows - the end product is excellent. And after the installation our guarantee paperwork and FENSA certificate arrived promptly. Really pleased we chose Marathon for our replacement windows.

We had four replacement windows, a large bay window and door frame with side window and composite door installed by Marathon. There was an expectation of problems with the front door as there were some potential issues with a course of bricks above the frame but, as it turned out the install went extremely well. When an install of this size is undertaken, people need to be aware that there will be unforeseen issues. What matters is how the installers deal with them at the time. Anthony and Paul dealt with all of these extremely well and everything was completed to the highest standard, as promised. I would definitely recommend Marathon to anyone needing such work done and will use them in future, should the need arise.

The team were all polite and mostly very good at getting back in touch. The products ordered were custom but delivered wholly according to spec which was impressive. When the special order handles arrived too late they were very prompt in coming out and fitting them too (no extra charges at all). While delivery times can be a bit long this is due to industry issues and they were very quick to schedule in fitting once arrived. A fault with one door was patiently tracked down and corrected. So, while nothing in life is perfect Marathon were about as good as it can get to managing everything to do with new windows and new doors. I don't think they were more expensive than anyone else would have been either.
