Decking- 4 Jun 2020
I recently had decking installed by Dean, he was quick to reply to the job in the first instance, then prompt in calling and arriving to measure up, quote arrived, and in just over a week later my decking had been completed. We are very happy, great job done. He even fixed my dodgy back gate on his way out 👍 Highly recommend Dean and I'll almost certainly use him again Clare G

The project was to construct a 15m2 extension to our rear lounge on the ground floor plus a 4m2 extension to the bathroom on the first floor. This involved foundations, walls and roof tiling in addition to the installation of a 5m long RSJ to support the first floor bedroom. Jamie was selected because of his recent training and apparent enthusiasm. He planned and carried out the work very well. Problems when encountered were discussed and resolved with professionalism and enthusiasm. The resulting work has been completed to a high standard and I am well satisfied with the result. The time taken was as planned, he worked on a daily rate which was to my budget. Jamie' strengths are a good basic knowledge of the building regulations, good communication skills with other workers, suppliers and inspectors and excellent basic brick laying skills with a eye for dimensional regularity and excellent final appearance. I would strongly recommend this young and enthusiastic tradesman for any similar project work involving use of his excellent bricklaying skills.

Extensions- 18 Sep 2024
Chris was quick to respond to my enquiry and came round to view the premises and offer a quote straight away. Chris and his team took down and old conservatory and turned it into an extension. All the team were great, even my super shy son was chatting away to the chaps after school. All works completed in the time frame and to a great standard. I took advantage by asking for other jobs while the guys were here, and Chris was so helpful. I will definitely be keeping Chris in mind for any future works.

I highly recommend Archway Building MK for their outstanding work removing our main structural wall and installing a supporting beam. Wayne delivered exactly what was promised—on time and at a fair price. His team was professional, kept me informed throughout the process, and made sure the job was done safely and to a high standard. What stood out was their reliability and easy communication. He was always responsive and easy to reach. He assisted until I got my completion certificate. I highly recommend Wayne for his services. Thank you, Wayne.
