Replaced the windows and doors at our scout hut. Cost effective, tidy and clean work with limited damage removing the old windows.

We have used this company for double glazing, conservatory and porch over a number of years. They have always been helpful, efficient and their work is first class. Recommended.

I recently had work done by this company and can't praise them highly enough. The two men who came to put my door and window in worked very well as a team as well as on there own. Lots of banter but very respectful and tidied up after themselves. It was a pleasure to have them around. Whe I contacted the office all staff courteous and answered my questions quickly and efficiently. Thank you to all the team.

Great service. We only had a single window unit repaired but everything was done professionally at a very reasonable price. No hesitation in recommending Marathon.
