The work completely was of a very high standard with immaculate attention to details. Jerry was punctual from the survey stage to the end of the work. He sorted little snags with the wall, separated the work area with a plastic sheet so the dust was minimised. After each day, my home was left clean and the job was progressing well. The end result looks great and no issues so far. I would recommend them 100%

Catalin is extremely skilled and I was impressed by his efficiency and the quality of his work and the others who assisted. Would 100% recommend Star Construction to others.

Stanley & his team originally came on board to build us a new rear extension which would house our kitchen as well as fit a new bathroom but as the project developed it ended up being near enough an entire house renovation and we're thrilled with the results. We still have work we would like to do to the outside of the house as well as a loft conversion and when we have enough money to take on those projects, we would definitely re-hire Stanley and his team. Highly recommend Stanley & his team.
