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.

Decking- 14 Jun 2022
James Hynes of JCH Home Improvements have just refurbished our decking area. We thought it was a straight forward job, just to renew the decking and a tidy up BUT the original wood was so rotted the whole area had to be renewed. Joists, upright timbers etc We are thrilled with what James has done, so much more work than anticipated but the end result is fantastic. Would thoroughly recommend JCH Home Improvements and we will be using the again.
