"Mario first did a a new shower block in September and has now completed my kitchen from a stripped back room to completion. My experience with him has been very positive, I find him honest, trustworthy and he has amazing skills in all areas. I found him transparent throughout and he always kept me up to date with everything. His work is to a very high standard and he cares about getting it right. I thoroughly recommend him and I will be using him again myself."

"Fantastic work carried out to an impeccably high standard. We were kept informed as to what was being carried out each day and wouldn’t hesitate to use Flex building services again. 10/10."

"I’ve used Mariusz for three separate bathroom projects and his work is consistently of a very high standard. He has a keen eye for detail and takes great pride in doing a job well. I’ll definitely be using him for future projects. He’s a good problem solver and comes up with excellent solutions to unexpected issues that arise during a full bathroom renovation. Any minor issues after the work was completed were dealt with promptly. I would recommend him to anyone considering bathroom renovations."
