Bathroom Fitting- 22 Apr 2023
Younger brother Anti was a professional and I would hire again but beware of the elder sibling as his workmanship his poor, here is a list:- 1) the cupboard fitted under the stairs was misaligned and the hinges are loose. Paint job was poorly finished too. 2) cupboard fitted across the boiler was all bent. Anti came and fixed it. 3) varnish across door and skirting boards were done once and therefore have an uneven spread 4) the floorboards did not have enough glue placed in certain areas so it creaks 5) grout in some time are missing 6) really poor sealant work on the bathroom 7) broke my £2000 TV and then hid the evidence. I only found out after placing the furniture back in its place. In contrast Anti did a good job in fitting the radiator. If you can Illicit promises of Anti only completing the job without the older the brother then go for it or else give them a wide berth.
