Carpentry- 23 Jun 2026
Alina, Max and the team have been amazing. Gave a great price, turned up and began working immediately. Quality is fantastic, so much so we have asked them to complete additional works. They arrive on time, work hard all day and left the house and garden in a clean presentable manner. 100% recommend them, multi skilled, polite, and reliable team that deliver quality work at reasonable rates. Will use them again and have already recommended them to friends and family

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.

Painting & Decorating- 1 Jul 2017
I would highly recommend these guys. They did a very high quality job decorating my lounge, dining room, hallway and stairs. They started the job on time, worked through the weekend to get the job finished in good time, left the place clean and tidy at the end of every day, and cleaned up immaculately at the end of the job. The price was also very competitive compared with other quotes I received. I hope they are available again in a few months time when I have more decorating that needs to be done.
