Plastering- 29 Aug 2025
I asked Daniel to check and price some pebble dashing job. Daniel was fair in his pricing. He was on time in commencing the work as we had agreed. He never left the site until the job was completed within a few days, hence causing least interruptions. I do recommend him and I intend to ask him to carry out works in future.

Extensions- 13 Nov 2015
We had a terrible experience with VRS Building (Rimantas). After months of negotiating our renovation project & a verbal agreement VRS pulled out at the 11th hour. Rimantas's at VRS took a bigger job and contacted us by email and said "It's nothing personal, It's just business.' They have no loyalty to their clients.
