  • Thrust into the construction industry I began working since I was around 12 years old building family homes and working with my uncles. Have always been good with my hands and enjoyed the satisfaction of seeing the results of my skills and diligence at work. Have had a stronger focus on carpentry and virtually anything concrete related over the course of the last 15 years or so. Some of these include separate entrances, basement and bathroom renos/finishes, underpinning, extensions/additions, placing, leveling and finishing different types of concrete aggregates. I'm very honest and won't touch anything I am not comfortable or competent with but will cooperate with other professionals in their respected fields of that situation is encountered. Plenty of references when needed. Please feel free to reach out anytime.
