Hired Ian to Build a single story extension and install new kitchen and downstairs shower room . Crew were very pleasant and very helpful in planning the the job ahead of them. Very pleased with the work carried out looks amazing Having to put up with an awkward neighbor didn't deter them from doing and completing the job. The price put in was very reasonable. When the work was ongoing the area was always left clean and as tidy as possible . I would recommend Ian 100% , and would use him again.

Came very quickly and completed the job (like-for-like electric shower replacement) satisfactorily, my only gripe is the price/cost. Said it would be about £250 - £350 at the start, on completion of the job the price had gone up to £480 and he wanted it in cash. Not much I could do when the job's finished and the guy's standing in the house wanting to be paid. On reflection I feel I have been overcharged and should have waited for the other responses to come in but needed it doing.

Half the laminate was laid, but I noticed the pattern joins didn't match up. They were unsatisfactory and I pointed them out. The tradesman was happy to lay the laminate again. This time it was done well. I'm now delighted with the overall appearance of my floor, although there are still some small areas, especially by the skirting, where the laminate hasn't been secured by the trimming. Apart from these small things, the service was friendly and the job was finished on time. I would use them again.

Sadly as much as the extension looks fine on the outside, there have been too many issues behind the scenes that we have had to get remedied, which has been a huge additional ongoing cost to us. The team are not experts and will not do a thorough job. We have recently had to deal with a big health and safety electrical issue due to their inability to do things properly.

Quoted on our work, which was accepted and deposit paid. Then four weeks out from the agreed start date, said he'd forgotten to include costs for a full roof replacement (hip to gable extension) so it would be almost £30,000 more than the original price. We could not move forward, and £2,500 of our deposit was not returned to us as steels had already been purchased and cut (but he refused to connect us with the supplier so we could retain these for use in our project).
