Bathroom Fitting- 20 Sep 2017
We hired Luca for a job that involved a variety of work across our entire flat. Being totally new to renovation work and having been stung by other builders, meeting Luca was a breath of fresh air – he was friendly, helpful and honest. Luca did an great job for a very reasonable price. He’s fairly new to contracting bigger jobs, but he’s got a lot of previous experience as a tradesman and his plastering in particular was perfect – we’ve had loads of compliments on the quality of his walls and ceilings. He was always on time, always communicated with us fully, and was a pleasure to have around the flat. He made a real effort to keep disruption as minimal as possible and was very patient with us about stuff needing to be moved from one place to another. It wasn’t the easiest job and there were a couple of problems and extras, but Luca takes a lot of pride in his trade and worked extremely hard to keep us happy. We had a couple of plumbing issues arise but he went well above and beyond to resolve them, coming back for 2 days after the job was due to be finished to make sure that everything was working properly. This is far more than we expected, and we did really trust that Luca wasn’t the sort of person that would leave anything unfinished. We’re so chuffed that we met Luca and with the excellent work he did, and would love to work with him again. Luca is going to go on to big things, so if you get the chance to hire him now, we'd recommend him without hesitation.

Extensions- 24 Jan 2021
We chose Gibbons and Sons for our Loft extension and new bathroom as they was one of the few firms who we contacted and was more then happy for us to view their workmanship during and after the build so we good see the quality of their works. They have been courteous, polite, very patient and accommodating to our chopping and changing of ideas. They helped us to bring our visions to life and offered advice when required without being pushy and driving a hard sale. They have been open and honest with our ideas and their recommendations and in some cases suggested a alternative more cost effective option. All in all we would highly recommend Gibbons and Sons for all types of building works.
