Extensions- 31 Oct 2020
This man gave me a good quote for an extension; much needed for my disabled husband. I needed a wet room and bedroom to accommodate his needs. To my horror (and expense) I discovered that he had no experience whatsoever. He was keen and polite but did not know that he was required to speak to building control. His response when I asked him was ‘oh yes’ tell him he is welcome to see what I have done. He had no idea how to read plans and kept blaming the architect for his lack of understanding. Given the hash he was making my benefactor appointed a site manager. He would not allow this. I moved out for a month (at great expense) with my disabled husband so that he could continue the build. Through this time I had no contact except from the building inspector who told me to get him off the job because he didn’t know what he was doing. The site was on a hill and no consideration had been given for a potential landslide which potentially could kill us. He was asked to leave the site given his ineptitude but his was after he managed to afford a new van out of us. 18 months on and at great expense I may just be moving in to my extension. The toll it has taken on me and my husband is catastrophic. He presents as a very nice man and actually did a lovely job on plastering over the damage he had created in my kitchen. I am sure, from other reviews, that he is an excellent plasterer however, should he answer your request on a build, don’t do it. Any of this is untrue H?

Extensions- 10 Jun 2026
Scott abandoned the work in the middle of winter after collecting several thousands of £££ in advance without completing or making safe (see attached photos). Due to poor quality of even the seemingly completed works (e.g inappropriate roof pitch/tiles/truss, improperly installed doors/windows & rising damp on internal plaster boards) the work was rejected by building control and I've had to pay another contractor again to remediate. Scott started the work on 15 Sept 2025 but abandoned site at the end of Feb 2026 with doors/windows/radiators only partially installed. Scott had originally committed to a 12 week build for completion before Christmas 2025 but the work dragged till end of Feb 2026 when the work was eventually abandoned. I have decided to take the matter to court after several unsuccessful attempts to get Scott back to finish the work or refund the cost of repairing / completing his work which is about £20k in addition to the roughly £70k I have already paid Scott.
