Very please with the job from Gary, it can be difficult to find someone to do the smaller jobs but no problem and an excellent price from Gary. He kept in contact at all times and gave me some useful advice as to which radiator to purchase, I just thought a radiator was a radiator! :-) Job was done very promptly and everything taken away with him, no mess left at all. No problem at all with 5 stars for Gary, he is also a very pleasant young guy, would I hire him again? for sure!

Gary and Roy did an excellent job of replacing my boiler. The work was carried out to a high standard, and they went out of their way to minimise any disruption. In particular, they avoided any need to uplift flooring or carpets. Both were very friendly and approachable. As a further testament to their approach, they carried out a repair to the dishwasher as part of the overall quote. I would have no hesitation in recommending them to anyone else, and will be looking to utilise their services again soon.
