Would absolutely recommend Lee and the team. I had three separate jobs that needed doing. They quoted me for each and did the work quickly and well. They were friendly, approachable, didn't mind answering all of my questions and gave good advice. I will be using them again. I am loving the finished work. Each of the rooms look fantastic. Thanks Lee.

Excellent plasterer and renovator. Years of experience in all aspects of building works. Confident and competent to transform any property. Passion for gardening/maintenance of properties inside and out.To me the first impression is a lasting impression. Most small jobs can be estimated via pictures makes life simpler for most working people. 50% of the job as a deposit to secure a job and 50% when finishing Is usually expected. Of course there are Exceptions for different jobs. Thank you very much for reading have a fabulous day.

It took him 2.5 days to install a new kitchen tap. Issues he struggled with: connection to a boiling water machine, no isolater valves, 40’ waste pipe and the hot and cold supply pipes were mixed up (lots of moaning about the previous builders), many trips to screwfix and parts purchased that were not required; in that time he did also change a Yale barrel lock.

Job completed October but by November asked for them to comeback as new sink put in was leaking badly and blocked - not flowing out but doing well coming up from the washing machine…all connected. Said would be back, didn’t. Rang from my night shift no answer even though he was using What’s app…now paying again for what they didn’t come back and sort out. Also, 2 cupboard doors came off their hinges, new tap had to be tightened, was v lose… and yes, I could easily have had my Belfast sink put in too Hoti.

Very happy with Catalin and his team! Renovation of my 2 bedrooms was well done! Humble guys, they don’t talk too much just come do their job and leave. Catalin is very understanding and approachable, understands the needs and the struggle of his customers and helps them. Also very good communication, he responds to his call/messages within an hour if not immediately. They did few small jobs which was not part of the quote for free!I would recommend him to friends and colleagues. Reasonable prices.

Florin's work on my new staircase was excellent. His work was clean and tidy. When there were opportunities to take short cuts, he didn't, always completing a thorough and professional job. He gave advice and talked through each of the options carefully. His work was completed on time and on budget. His team were courteous, polite and cleaned up every day.
