Our renovation work was mainly 2-folds: 1) replace my existing tub-shower with walk-in shower; and 2) replace my old sink counter tops. For these works, almost all materials were supplied by myself, Cornerstone was hired primarily for their labour.
Over all, after more than 6-months' evaluation period, we are very satisfied with their work. Heiner is an upstanding person, and I recommend his company highly. I will not hesitate to recommend him for such reno works. Cornerstone's quote was a fair one and Heiner's team addressed all my concerns during the course of the work.
I was pleased by Heiner's team member's (Johnathan) persistent commitment to ensure that the new shower stall would not leak and all water would drain out smoothly. If I have any negative point to make with Cornerstone's work, it would be that their finishing work was a little disappointing -- grouting & caulking was not proper, small leaks were detected from the new sinks (however, both these concerns were addressed by Cornerstone after the work completion).
Thank you Heiner! My kudos to you and your team for a great job.
