Painting & Decorating- 29 Apr 2025
Nathan, Daisy, and Dan renovated and redecorated the front of my neglected Edwardian detatched house. Nathan replied to all my posts on Mybuilder.com immediately. He visited the property at the agreed time, and gave a thorough and detailed analysis of extra problems I had not forseen. He emailed a very reasonable quote the same day. The team started work within a week after I accepted the quote. They worked unobtrusively, doing a thorough job, explaining at the end of each day what had been done, and explaining the next stage. I would recommend them.

Bricklaying- 18 Sep 2025
The job went well. Craig was a bit more expensive but it was worth it for peace of mind. I had a lintel replaced which was not straightforward. The plasterer also commented that the work was done very well and to a high standard. The guys left the place clean and tidy on completion. Yes I will recommend Craig for any brickwork.

Plastering- 23 Nov 2016
Bill quoted for the rendering job but I also had him quote for some internal plastering. He has completed the plastering with the rendering on hold for now. I would highly recommend Bill who provided a detailed quote and when asked to do a bit more kept me informed of the additional costs. He was reliable as in turning up when arranged and worked hard. Having used Plasterer's before I can say Bill was the tidiest I have experienced and obviously respectful of working in someone else's home. His work was to a high standard and I got the impression that he wouldn't be happy if a job wasn't done right. I would recommend Bill for your plastering needs.

We have a lot of quotes for our porch renovation and Grant stood out because he was calm and non pushy. He gave his advise and worked with me to achieve my end goal. He is very professional, polite and respectful. There have been occasions where I have asked a number of things to be altered and this has been no trouble for him at all. I tend to use a lot of builders and I would highly recommend him and I will be using him for my next projects.

Bathroom Fitting- 3 Sep 2018
Mike was very professional from the start of our process finding someone to build our en suite bathroom. He came up with the best solution for the long soil pipe we needed and demonstrated the previous experience to make it work. He even tried to fix our existing toilet when he had just come to quote! Mike and his colleague Kear worked hard through a very hot week in July and always left the house tidy each day. As long as you keep providing tea with 2 sugars they just keep going! They even fixed our garage door, probably out of frustration of opening it each morning. I would recommend Mike for any bathroom or plumbing work.
