We hired Danny to replace our back windows with some nice french doors. From the moment we first met him we could tell he is extremely knowledgable and passionate about what he does. On the installation day he went about his business in a very professional and polite manner, causing us minimal disruption and we were very pleased with the final result. It’s very refreshing to see someone take such care and pride in their work and we wouldn’t hesitate to hire him again or recommend to others.

Danny fitted a new front door for us last week (September 2025). From start to finish of the decision process Danny was friendly and professional. His workmanship is spot on and we are thrilled with our new door. We wouldn’t hesitate to recommend his services.

Highly recommend! We had one of our bedroom windows closed up which was completed to a very high standard. Then, had the dorma cladding removed and replaced which DMK exactly colour matched to the front of our house. The project was completed incredibly well and within the time frame that was originally stated within the quote. They were friendly, polite and left the work area very clean. Thank you so much! We are looking to book in our next project with DMK very soon.
