Paul has done work for me over the past 16 years on various projects. Always spot on with great attention to detail. Paul has just finished my shop fitting in the designated 2 week closure. He worked tirelessly, evenings and weekends to ensure everything was done on time. He project managed all of the other tradesmen and gave some ingenious ideas. He is truly a remarkable gent and goes above and beyond in his commitment and perfect workmanship. A***
