Fencing- 4 May 2025
Richard Was the first to respond to my advert. I liked his profile and he was local. He came next day to quote and was on time. Promised I would have quote next day, which i got. Agreed the quote. He told me the day and time he could start and he cameon time. He completed the work quickly(partial wall rebuild, new fence and new gate and ppointing to back of house) and did it on time. Cleared all the rubbish. He was well mannered, professional and his workmanish is of a very high standard.

Extension Builder in Bolton, North West England
Joiner with Precision Craftsmanship and a Commitment to Excellence.In the world of skilled trades, few disciplines demand the balance of art and engineering quite like joinery. It’s a craft that requires more than just the ability to cut wood and follow plans—it calls for a level of care, precision, and integrity that separates an average tradesperson from a true craftsman. With a passion rooted in quality workmanship and a mindset fixed firmly on getting the job done right the first time, I have built my career as a dedicated joiner known for my punctuality, professionalism, and sharp eye for detail. Early Foundations in Craftsmanship My journey into joinery began when I was young going to work with my dad on weekends and grew from there. I did wood work in school and then finished off my qualification in college.i am Tradesman You Can Trust Joinery is more than just a trade for me—it’s a profession and a craft that I’m proud to be part of. With every cut, joint, and finish, I strive to leave a mark of quality, and to be the kind of professional that clients remember for all the right reasons. If you're looking for someone who brings precision, reliability, and a craftsman’s eye to every job, I offer exactly that.

Extensions- 21 Oct 2019
Damien is a number of weeks into my build (rear extension of a period property) and he's been a breathe of fresh air after numerous efforts to find a builder who would do what he said he was going to. I believe he offers great value, he is the only builder I've found that provides clear updates, manages expectations and turns up when he says he will. Great work ethic, don't feel like he's looking to create more work/move goal posts to get more £ And finally he clearly knows what's he's doing, have no concerns with walls coming out to fit steels etc

Extensions- 24 Apr 2023
Hi all readers like a lot of people I was anxious in starting my building work and I had heard night mare stories from other people about there extensions and builders. My daughter found Hussain from my Builder. Hussain came to see the house for the job. Hussain has done a great job on my rear extension. He is reliable, trustworthy and has been attentive to all the work. I was at work most of the time Hussain and his team got on with the work and if they needed me they contacted me and visa versa. I didn't need to be on site all the time or take any time off from work. Its very difficult to find a good builder like Hussain who you can trust. Hussain ensured I stayed in my budget and this was so helpful. Hussain does not beat around the bush. Hussain is straight forward and honest. Hussain's work is excellent I would recommend Hussain any day of the week. If anyone needs to come and have a look at my extension I will be more than happy to show them around. Top guy and a big thank you to him and his great team.

Joinery & Cabinet Making- 8 May 2026
We’re absolutely delighted with our new built-in wardrobe and couldn’t recommend Vasili highly enough. From start to finish, he was patient, professional, and incredibly hardworking. He really took the time to understand what we wanted, offered helpful advice throughout, and never rushed any part of the job. What stood out most was how honest and considerate he was with costs. Rather than encouraging unnecessary extras, he was genuinely keen to help us save money where possible while still achieving a fantastic finish. It’s rare to find someone so skilled who also cares about giving customers real value. The workmanship is excellent, the attention to detail is outstanding, and the finished wardrobe looks amazing. We’re so pleased with the result and would happily use him again for future work.
