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!

Extensions- 29 Jan 2015
PM Building epitomise what a modern day, professional building firm should aspire to be. Transparent pricing, a friendly team working 6, sometimes 7 days a week to get the job done quickly, an eye for detail and very high standard of final finish. All comms and the overall work is run through Bart, who answers to phone, text or email quickly and frequently outside normal working hours. This is ideal if you work during the day and cannot be around to oversee things directly. We also got PM Building to make us a bespoke kitchen, again very high quality and millimetre perfect. If I had to find some negatives, they are not the cheapest company you could find, but there again you get what you pay for; also, we developed a few issues with some retaining walls in the garden, however, they returned when I contacted them long after the work had finished and fixed them! All in all, an excellent, honest and professional company to deal with. I would, and have, recommended them to friends...nuff said.
