Bathroom Fitting- 9 Jan 2015
Aggi and Pedro were excellent. They helped me to decide what fixtures and fittings I needed (including also doing some research themselves) and when it came to fitting the new bathroom they did it to a high standard and were tidy/cleaned up after themselves. I would recommend them.

Bricklaying- 17 Dec 2024
They initially gave a fair price and a date and timeline that fitted with our needs. Subsequently they over ordered on the bricks so we had over 100+ expensive London bricks left over and they under ordered on sand and cement.(Luckily the shop took them back but we had to deliver them there) The job took far longer than they had said although the poor weather did not help much which could not be helped. The worst was that the wall was finished so that the latch of the gate could not be fitted as the wall was a bit too long! The wall looks good but their customer service and time given for job as well as ordering materials needs some improvements. They are pleasant workers, not rude in speaking

Plastering- 25 Feb 2020
Rob provided a very reasonable quote and started work on time as agreed. He scraped the artex, boarded sections, prepped and plastered both ceilings over two evenings to a very high standard. Both ceilings were ready to paint after a few days drying and were smooth with no trowel marks or hairline cracks at all. Rob also assisted with measuring up my kitchen for a new kitchen to be installed, he provided a better quote than Wren to fit the new kitchen, I will be proceeding with Rob to fit my new kitchen units based on the advice he has given me and the high standard of work he has carried out for me over the past couple of weeks. I would highly recommend Rob to anybody and I will be contacting him again for any future work I need assistance with whilst refurbishing my new property.
