Stonemasonry- 5 Sep 2026
Really pleased with the work carried out on our property, the two fellas were fantastic from start to finish and worked really well as a team. John came up with some really innovative solutions that only someone with an extensive experience in stonemasonry skills would do, and the finished result looks great. The work was completed quickly, efficiently and, importantly, at a very fair price. Both were friendly, professional and clearly took pride in their work. We would have absolutely no hesitation in recommending them to anyone looking for similar work. We may well be getting back in touch ourselves for some further work in the future!

Rating: 5 out of 5
Extension Builder in Castleford
Over 20 years experience in the building trade, from apprentice to where I am now. Confident in all aspects of building projects from a small garden wall to a full new build house and everything in between. Great customer relationship is key, with communication throughout a project to ensure the whole job is done to the customers requirements. Although I am based in Doncaster travelling to the surrounding areas is no issue. For projects such as extensions and new builds I can fully project manage and provide trusted trades to complete electrical and plumbing works. I am no stranger to the current building regulations and all major work is overseen by LABC (local authority’s building control). References available on request from previous projects. As a small business, I thrive to offer a quality service throughout.

Bricklaying- 21 Feb 2025
Wanted the concrete steps on the front to look more appealing with better use as the old steps were not that great and a bit of an eye sore. Straight from the start A Shay was very friendly, professional and understood what we wanted. During the time from giving me a quote to the night before they arrived to do the work I was kept updated. We are really impressed with the work done and couldn’t have asked for anything more,very friendly, professional workmanship, knows his stuff and clean and tidy work. 1000% would recommend and definitely use again without a doubt.

Steve Scarrot built my double extension and I can honestly say, wow what a great job. I can’t say a bad word about it. Steves workmanship and knowledge on the building game is second to non. His hard work and dedication to work is first class. He was prompt, never late and did exactly what he said he was going to do. His quality of work was exceptional and he never tried to cut any corners he was first class all the way. An absolute professional and a credit to the industry and I’d happily have him work for me again.
