Carpentry- 5 Jan 2025
Aaron initially impressed me with his commitment and fair pricing, delivering and installing staircases well. However, when he offered to tile a bathroom, things went downhill. Instead of handling it himself or assigning someone he trusted, he brought in a tiler he’d never worked with before. The results were disastrous—uneven tiles, poor grout work, and an overall lack of quality. Aaron offered to fix some issues but didn’t supervise the work, leaving it to me. His repairs only made things worse. After the job was finished, he ignored my detailed list of tiling mistakes and stopped responding altogether. I had to hire another tiler to fix some issues, but many problems remain because further repairs were too costly. While Aaron is an eloquent speaker and seemed committed initially, his actions didn’t match his words. I cannot recommend him and caution others not to be swayed by small talk or promises without clear oversight and proven reliability.

Andrew did a fantastic job in installing a new bathroom floor and bath suite. As the bath had leaked below, he also replaced the ceiling.

Bathroom Fitting- 26 Aug 2026
Reza quoted two weeks to renovate my bathroom but finished in just a week and a half. He brought in a team of three who worked efficiently and completed the job to a high standard. They were polite and courteous and took great care to cover all staircases and carpets, ensuring no damage was done to the house. When extra help was needed with the heating, a specialist engineer arrived promptly and completed the job smoothly. I highly recommend his services.
