    Tradesman was really polite and helpful - We then noticed that the handrails were loose he came out to look at them and agreed and said he would get them fixed. Since then the paintwork is peeling also. That was over a month ago and Sigma just don't want to know. Spoke to him today and he says it's not his problem. He said don't call me as it stresses him out! He will come and do it when he can but no idea of when. All I am asking for is an idea of when he can fix the work. Overall worked well but if you need any after service STAY WELL AWAY - need to find someone to do the work now...

    Ionut did a fantastic job. Really pleased with the outcome. Would definitely recommend. Only wish would be that the old bathroom and cardboard etc was removed.

    Having spent a lot of time searching for the right builders, as soon as I met Ionut and Florin, I knew they were the right people for the job. They understood what I wanted, put me at ease, were able to understand and predict my needs and expectations. The whole time being super friendly, patient and professional, nothing was too much trouble :) The work completed is excellent, can't fault it and I am truly very pleased with the outcome. I would not hesitate in recommending Ionut and Florin and looking forward to having them back next year for another project.

    Always a bit of trepidation when getting a new builder in to do some work. Good first impression from both of them, on time, explained what they would do and got me the quote punctually. Started the work on the agreed date, offered some advice about the job, were exceptionally good with , Hard working and pleasant to deal with, made a great job of the work , I intend to use them again and would certainly recommend.
