I recently hired Vithesh for a loft conversion, and I couldn't be happier with the results! He completed the project with exceptional quality and efficiency. The structural floor beams and steel structure were flawlessly installed, and the roof comes with a reassuring 10-year warranty. What impressed me the most was his ability to complete the structural job in just 3 weeks, even though the original estimate was 5 weeks. His commitment to meeting deadlines and delivering high-quality work is truly commendable. I’m absolutely thrilled with the outcome and will definitely be calling him for any future projects in my home. Thank you, Vithesh, for a job well done!

Extensions- 2 Oct 2024
He did the extension well, brick work is good, rendering on front of house good, terrace and wall with the neighbours good ,toilet under the stairs good, dividing wall in the living room with sliding doors good, kitchen installed good. Fence wall in front of house good brick work wrong bricks but it’s ok. Herringbone parchet wrong with gaps and lifted, rendering on the side of house wrong with marks, the new boiler took 2 months to make it work and the radiators still don’t work. Electrical work bad, after bringing another engineer to check we discovered at the boiler live cut cables that were loose and veri dangerous. Took 4 months to finish job we waited one month for the plumber who either way did a bad job. Laurentiu did not finish the job because of plumbing and rendering, and we ended in bad terms, he left us money to compensate for it. I would recommend him for extensions and any brick work, he needs to improve in pluming, electrical, flooring and rendering.

He is extremely hardworking and knows exactly what he is doing, I would definitely recommend him to anyone looking for any gardening work done. Even though by himself he did all the work to such a high standard, and is very mannerful and polite.

We've been seriously impressed with Pawel and his team. They opened up our rear dining room/kitchen wall using an RSJ, following our engineer's drawings perfectly. They also did a few bits of plumbing and bricked up one of the windows at the rear, which is where the new kitchen will be fitted. They were incredibly tidy and really pleasant and courteous to be around, which my wife was so grateful for given we live in a busy family house (most builders are not like this...), I can't thank them enough! We will definitely be using them again in the not-so-distant future!

Demolition- 15 Jun 2024
Shane did an excellent job when he demolished an old unsightly concrete coal bunker. He obviously had all the right skills and the right tools and was happy to do a couple of small extra tasks. He gave some good advice about a separate maintenance issue that may well save me money. Communication was good and he arrived on time. Highly recommended.

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!
