I would highly recommend Johnson's Builders.
They were recommended to me by my neighbour who had used them and I was very happy with the results of my side and rear chalet house extension, also with my new kitchen fit out and dining room refurbishment.
The workers were friendly and polite and cleared up after themselves as much as they were able. I knew that if I had any problems I could call on Robin at any time .
