    “Thanks MNK for our new windows and door. We are early pleased we chose you, and are really happy with your workmanship.”

    Kathy Thompson

    “Matt and Nicky came out to my house about 5 years ago to fit new windows. I had previously had a very bad experience with window fitters from a large glazing company in a previous house so was a little worried. I have to say I didn’t need to be! They were amazing! Friendly but yet professional, clean and tidy and nothing was too much trouble for them. They were quick and efficient”

    Gareth Milner

    “Fantastic service and very friendly people to work with and professional in all aspects of door and window fitting.”

    Drew Prior

    “Mathew and Son were fantastic. Arrived for the quote and to fit when they said they would. Did a fantastic job and more. Super reliable, I nearly overpaid, but Mathew was honest enough to remind me I had already paid for the door and fitting. Lovely bloke, excellent craftsman. Competitive prices. Look no further, you’ve found the right man for the job.”

    Jarod Garrington

    “Thanks to MNK for doing such a fantastic job on our windows. Can’t fault them in anyway. Great quality workmanship, reliable, on time, polite and competitively priced. I’ve used them several times and they’ve also done a fabulous job on my mothers windows too. Have no problem recommending them Thanks guys”

    Kate Sillitoe

    “Perfect job, done exactly when planned and without mess or fuss. Real pride and attention to detail taken in the work. This was highlighted by the fact a unit with a small manufacturing fault in the frosting was already reordered before I even knew there was a problem because they weren’t happy with leaving anything in a state that wasn’t spot on. Wouldn’t hesitate to use again or recommend to others.”

    Beth and Jase

    “Great service from Matt and Nicky. Excellent fitting of the bi-folds, rectified issues created by our builders and went above and beyond. Thanks both, cracking service.”

    Jenny Ford

    “Can’t fault the work. Friendly, trustworthy and very tidy. After the work was done, they even offered to replace the glass in the door as it had a small scratch (I hadn’t even noticed). Would definitely recommend.”

    Jemma Sinton

    "Amazing job completed today by Matt and Nicky!  Brilliant work, friendly and very professional.  I can’t stop looking at my beautiful new French doors, even my little boy said “Wow Mummy look” when he first saw them!"
