Elliott has to be the best decorator/ builder I have used. On time with works and no lies or excuses!!! After posting my job he call me within 30 minutes to arrange a visit. This was the following day. When Elliott arrived he understood my requirements and saw my ideas and advised when he thought from his experience, would work better. He was very polite and professional. I needed the work done within 2 weeks due to carpet being laid. He completed the works within 7 working days. The works involved, Removing a wall, Removing all woodwork, Boxing out pipes, Plastering, New coving, New skirting, New architrave 2 doors, Building an under stair shelving unit, Moving a socket, sky cables, internet box, Removing radiator, Painting of all new plastered walls ceiling and woodwork to my chosen colours. I was even able to get him to squeeze in some additional works. This was creating shelves in my airing cupboard upstairs and boxing out pipes in my hallway. Elliott’s communication throughout the works was great. Even if he was unable to get round my house he would let me know at his earliest opportunity. Very very tidy during works. I have a 3 year old and Elliott made sure it was left safe every night. The finished works are to a high standard and he even popped back to do a bit off snagging on a Saturday morning. When I say snagging it was a few paint marks, re-laying my old carpet and dropping my keys off. I will be using Elliott in the future.

Very friendly and polite team. James and Lewis did a fantastic job rebuilding my boundary wall. Both had a high level of experience within the building trade. The wall was rebuilt to match the existing wall with great skill. Minimal mess was made during the work and everything was cleaned up after work was completed. I would highly recommend them and use them again.

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.
