Conversions - General- 9 Dec 2022
Fantastic father & son team. Wayne has extensive experience, but always listens to the clients and advises accordingly. As a Structural Engineer, I am well versed in the trade, and found it a pleasure to work with both him and his son and can testify to the high quality and caliber of the job delivered. On time, on budget, an honest, approachable good man. He will be the first recommendation I give for any further works required both for myself and my own clients. Without a shadow of a doubt I would use him again on further work to my home next year.

Painting & Decorating- 27 Nov 2025
Great job at a very fair price, and nice guys to deal with. Freshened up a room that had been wallpapered about 40 years ago and not touched since, with blown plaster in the corners and generally awful walls. Looks great now.

Bricklaying- 10 Jun 2020
Mathew visited me promptly, measured the work that needed doing, and gave me some helpful advice. Next day I received his very reasonable Quote (. As it turned out we decided to go for a wooden fence.) I was quite impressed with Mathew and the efficient and helpful way he dealt with me. I would definitely employ him if I need any building work done in the future. Thank you, Mathew. George

Easy communication. His son gave me a day and time and completed the work quickly and very well. Also finished the work of another builder who hadn't done a good job so everything looks great now. Very easy to talk to and professional. Would highly recommend Colin Drew.

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Newtown extension builder’s ability to deliver a result that meets your expectations.
