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%

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.

Hired Ian to Build a single story extension and install new kitchen and downstairs shower room . Crew were very pleasant and very helpful in planning the the job ahead of them. Very pleased with the work carried out looks amazing Having to put up with an awkward neighbor didn't deter them from doing and completing the job. The price put in was very reasonable. When the work was ongoing the area was always left clean and as tidy as possible . I would recommend Ian 100% , and would use him again.

We used TAC Building for a full bathroom renovation. From the moment we met Tom, we were really impressed with his knowledge and experience in the industry. Our bathroom looks amazing, and his whole team worked really hard every day. The quality of the finish and the attention to detail are things that you only find in high end tradespeople, and he is definitely one of those. We have used Tom for other jobs since, and will again in the future. Thank you Tom.

Had a quote for roof repair which included for 1 missing tile, re fitting existing tiles, repairing flashing and gutter cleaning did not accept quote. On advice from another roofer just had the one missing tile replaced since there was no evidence of any leaks inside the loft or 2nd floor ceilings.
