“Found Marlin Windows following a google search, what a great local company. Showroom visit really surprised us & we were given very helpful advice on how to measure opening for doors. The product is superb and we’re delighted with how they’ve fitted in. Marlin also recommended Core Glass who measured and fitted the doors for us. Several phone calls to ensure order was correct…”

TREVOR PATERSON

''We found Marlin Windows exceptionally helpful and friendly to deal with. They have supplied over 40 Heritage style windows and some large 4m sliding doors for our new ‘forever home’ self build project that has been years in the planning so detail was important. Marlin provided a superb service with advice, guidance and help that made choosing them easier as windows were a massive design feature of our house. They provided small samples of the frame colour and style to look at on site which was important. They offered good value and the quality of the window is excellent. Would highly recommend''
