My French doors and windows are beautiful
Marlin windows have been an absolute pleasure to do business with. The after care has been superb and Adrian couldn’t be more helpful - stepping in to help when we had a problem with our building project. Can’t recommend Marlin Windows highly enough. Thank you

Very pleased with the quality of the two sets of Smart Visofold 6000 bi-fold doors to replace our existing uPVC French doors with glazed side panels. The narrow sightlines are a great improvement on the old frames, allowing more light to flood in and are visually are much cleaner and simpler. Cost-wise Marlin is very competitive in relation to other manufacturers.

From our initial contact with Marlin Windows we have been very impressed. Super customer service, they actually answer the phone and call back promptly if they’re not available. Hannah dealt with the quote patiently and efficiently and Adrian was very helpful throughout with technical advice. The final products, we chose Heritage doors and windows, look stunning. Thank you.

I ordered three sets of doors to self-install: the team at Marlin were really helpful with all my technical queries, which helped make sure my orders were mm perfect and the doors all went in smoothly with the glazing bars all lining up precisely. They look great - will do it all again in our next house!

We used Marlin for windows and internal Critall style doors and screens using Alitherm Heritage products on our recent self build project. Marlin are not local to us but provided an excellent service from quotation, advice, redesigns and with very detailed comms throughout. The recommended installers Dayton were also superb and very thorough on site survey. The windows and doors are the talking point of our entire build. Adrian from Marlin said that windows become the eyes of the house and I didn't forget that - our eyes are simply stunning. Would highly recommend.

It's really difficult to know which company to go with as windows are such a huge chunk of any building budget & there are so many providers to choose from. Marlin Windows were reassuringly professional, calm & helpful from first contact which made the decision to use them so right. The pre-sales team were full of advice - not in the least bit pushy contrary to stereotype - & the advice was spot-on because they'd done it all before. The planning & timing was also spot-on (in fact, they took our building lag in their stride with no fuss - again, they understood what we were doing), the installers

Excellent experience from the first meeting to the installation. The staff were very helpful selecting the style, colour and function. We couldn't have asked for a better window door company to work with. The install crew were very courteous and very good. They have all worked in the company for a long time which gives credit to Adrian and his company ethos. We are very satisfied with the end result, the windows and doors look amazing, I wouldn't hesitate to refer Marlin Windows to any one. Thank you Adrian and crew!!!

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
