I was lucky enough to have Haroun on this project of side extension and outside building. He is such a professional guy and always committed to do his work up to the standard. He has been very nice to us and always responded whenever asked to do additional jobs. He is very honest and trustworthy and his team has been very wonderful. I'm very happy with work he did in the house and would hire him again should the necessity arise in future.

Groundwork & Foundations- 7 Feb 2026
Oli carried out the groundworks and demolition at my property and was on site every day with his crew, fully committed and hands-on throughout the job. I am an architect, and this was work on my own home, so my expectations were high. Oli met those expectations fully. He has a strong knowledge of groundworks and demolition, works carefully and methodically, and you can tell he genuinely enjoys what he does and takes real satisfaction in delivering the work exactly as required. He was always in a good mood, easy to communicate with, and a pleasure to have on site. I enjoyed discussing the project and hearing about other jobs he has completed over his 23 years of experience, which clearly shows in the quality of his work. I would highly recommend Oli for any groundworks or demolition works.

We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.

Extensions- 29 Apr 2026
Heera, Jagthar and team was my first personal experience with builders. Let me tell you, it was a pleasure to have them do our porch and other renovations in the house. They are so courteous, hard working and provided a great service. Firstly, I had a comprehensively written quote breaking down all of the steps required. Heera then ensured to keep me in the loop of any developments/any changes of plan required, outlining the reasons why and options, making it easy to understand and work together to completion. Their finish was to a high quality and they would always go the extra step to ensure this. I highly recommend AS Builders for any job and will definitely use them again in the future, and would recommend to my friends and family also. If you are considering them, grab a free quote and go from there... That's what I did! Thank you AS Builders for our renovations!

Satnam and his team arrived promptly on time as agreed, i was highly impressed with the perfection they did the job. The room was total mess and they converted that room into a beautiful yoga studio. They worked fast and to perfection. The price was good. They did not ask money in advance which was good as i paid them after the job was done to my satisfaction. Now i have also asked them to do more work in my house. Thank you Satnam and the team.
