What some of our customers say

Alix and his team did a great job plastering the underside of a tight rotating staircase. A difficult job due to the steepness and tight space to work in but very happy with the result. Also very pleased with the boarding and skimming of ceilings and walls, all done to a great finish. Very friendly person and competitive quote. Overall very pleased and would recommend.


Richmond Plasterers have done a very neat job on our New Build house and were efficient, tidy and very reasonably priced. We are very pleased with the finished job. Many thanks.


Alex and his team did a wonderful job rendering front and side of my house. Always on time bright and early and very organised. They removed all the pebble dash right back to Scratch coat and a smooth render finish. I highly recommend them and thank you for a great job.


Alix and his team did a great job of turning this job around quickly, completing a full flat re-plastering to a very good standard. Worked long hours to ensure that they met their promised timeline for completion. Many thanks for a job well done!
