Plastering- 11 Apr 2026
Absolutely thrilled with the work carried out by Harman. The skimming has been completed to an exceptionally high standard - the finish is incredibly smooth and completely seamless. Harman and his colleague were professional throughout: tidy, courteous, and very polite. They took great care to properly protect and cover the surrounding areas, leaving everything clean and intact once the job was done. What really stood out is their attention to detail and commitment to getting everything perfect - even offering to return for any final finishing touches if needed. I honestly couldn’t recommend them highly enough. Brilliant job from start to finish.

I was very pleased with this company so much so that they are starting a new job for me November 15. The building firms carried out a full loft conversion for me installing bathroom, brickwork, joinery, plastering, Roofing and installation of windows and double glazed doors. I have high standards and want everything to be completed in the same way, the workmen respected my home and always left if clean. My main contact was with the owner of the company Dwight Lynch, he was very flexible and Nothing was too much for him to do. He has an attitude which I like in a builder "customer not always right but must be happy" he provided me with ideas along the way and where things did not go to plan due to my own instructions he worked around the issue and provided suitable alternative options. I was very happy with the pricing of the job and feel that certainly I would recommend him and also I would use him again. He and his workmen were all trust worthy and I gave them keys to my house to carry-out work whilst I went on holiday. I had no concerns when I came back everything was as I left it.

Extensions- 18 Jan 2023
We highly recommend THG building solutions, they have built a double story extension for us, and from start to finish they were always on time, polite and professional on every aspect. Most importantly they delivered what was promised according to the initial budget and on time! No delays or surprises, just honest and reliable service. We have been approached by several neighbors to comment on how beautiful the extension looks and how quickly it was all done! Overall we’re very happy and glad that we chose Charles and his team as our builders.
