Conversions - General- 7 Feb 2025
Stephen and his Team were utterly professional, their work was faultless and we couldn't be happy with the job. We had a wall removed in the kitchen which needed a support putting in, and a wall removed in the bathroom and a doorway sealed up. Right from my initial contact with Stephen we got got a good feeling, his quote was the most competitive but we had already decided to go with Stephen anyway as his experience, expertise and integrity were obvious as talked us through the job and what would be required. Their work was fast and to a great standard. We were very impressed with how clean Stephen and his Team managed to keep the house throughout all the work (especially as we have black mortar in the walls), they cleaned up throughly every evening and it made life so much easier on us.

I originally booked multiple building companies for a quote for my home improvements. Carl was friendly on initial meeting and give me good explanation on how best to carry out my project with the maximum impact to use my space. He was very efficient in getting back to me with his quotes and I could clearly see the breakdown of each individual project. The timescales that he recommended were also managed within the given timeframe that was advised. The company was very clean and tidy and always made sure that any rubbish was taken and disposed of the same day. The quality of the workmanship was very good and I feel that the standard of finish for the end results were also very good.

Plastering- 4 Sep 2020
Living room walls and ceiling plastered. Communication leading up to the job and during was great. Richard was great to deal with. Started first day and arrived early which is always a good sign. I went away for a few days whilst work being done and Richard kept me informed and sent through pictures and video. Really, really pleased with finish and can’t wait for it to dry out now. Cleaned up once finished too. Richard to come back to finish off once other works done and this hasn’t been a problem with him either. Would definitely recommend.
