Extensions- 7 Apr 2025
Quotes were provided and the job was agreed upon. The project involved a full house restructuring and extension build. However, after several stages of work, communication with Jas was lost, and his co-worker took the lead on site. Several issues arose, such as recommending smart plumbing equipment for purchase, but their plumbers were unable to install it. The tiling, skirtings, and tiles were not completed. Tiles around the columns were cracked. After Jas's team abandoned the project, another plumber had to install all the remaining items. The job was left unfinished, and we had to find alternative contractors to complete it. Significant time and money were wasted due to persistent communication problems, failure to issue invoices, and numerous other issues. Eventually, Jas and his main labourer stopped responding and disappeared, ignoring phone calls and WhatsApp messages. Be aware of these potential issues.

Really good team. The work was excellent. The only thing to comment is that the team could have finished the work faster but overall I’m happy with their work. Very involved and caring team. It felt like they were doing their own bathroom. Good price as well.

Carpentry- 4 Jun 2026
I recently had Alex install my 12-foot pegola, and I couldn't be happier with the result. From start to finish, Alex was patient, listened carefully to what I wanted, and took the time to ensure everything was done properly. He is hardworking, reliable, respectful, and kept the work area tidy throughout the project. What impressed me most was how efficiently he worked without compromising on quality. The pegola was completed to a very satisfactory standard, and the finished result looks fantastic. I would have no hesitation in recommending Alex to anyone looking for a skilled and trustworthy tradesperson. I would gladly use his services again for future projects.

My house was old and its condition was poor. Much were needed to be fix. The original kitchen layout were also inconvenience to my wife. I need to have all these changed under limited time. This builders have a team of specialists on almost every aspect. They gave me variety on the layout design and choose of materials. This saved me money, time and tons of trouble to find difference contractors. The after service and their respond time are very good too. I hope by sharing my happy experience can save your money and trouble to find a good contractor.
