Restoration & Refurbishment- 2 Apr 2026
Really pleased I chose Leigh Matthews for this job. We were taking over a building that was unoccupied for 18 months and there were some issues with that, The team were excellent, and they finished the 4-week job on time, and right on budget. They were helpful and considerate and left the premises clean and tidy. They were also able to help out with some problems with the plumbing that were not in the original scope. I loved the way they did the estimate and the invoicing. Breaking all the items down into the individual tasks and at the end of each week, itemising which tasks were complete and a %age on those in progress. I would not hesitate to employ them again

Carpentry- 19 Jun 2019
The job actually got bigger as the time went on, once I’d removed the old wardrobes the walls needed plastering and the laminate flooring needed extending, so a “simple boxing in job” became a nightmare! Dan’s professional approach was unquestionably and his ability to be able to fulfil all of the requirements was brilliant. The room and surrounding area was left immaculate at the end of each day and he was always prompt arriving in the morning. The finish of the work was 1st class and I can’t recommend him enough, if any one would like to see his work, then their more than welcome to view.
