What Our Clients Say

Garage Conversion/New Garage/Create Kitchen Diner

“We are very pleased with the work undertaken by Sean and would certainly recommend him to anyone else requiring building work to be undertaken. He was personally on site every day, worked hard and has quality tradesmen as part of his team. Sean also gave us good tips, advice and ideas, as did his colleagues and for that we are also very grateful. His quote was competitive, he kept us fully informed of what was going on and he also kept disruption to the minimum, while always ensuring that our property was secure. He is a very tidy worker. Our son is a QS for a major house builder and he too was impressed. At the end of the job Sean presented us with an impressive folder of guarantees, instruction booklets etc and he was at pains to stress that in the event of any future issues with the work undertaken we should not hesitate to contact him. The work was finished ahead of schedule and to a very high standard”

Mr & Mrs Mackenzie

Furzton Garage Conversion

“S J Dunphy Construction LTD completed a garage conversion and extension for me in just six weeks. From the outset Sean and team were fast to respond to produce quotes, worked exceptionally hard to deliver the work in a very fast time and produced everything to an high standard. You don’t just get a job done but ideas along the way too which can enhance the project. They are reliable and an added bonus is keeping the site and the house as clean as possible along the way.

After previous bad experiences with a builder I cannot recommend S J Dunphy Construction LTD enough. In fact my neighbour is about to have his own garage converted after seeing the results!”
