Patti & John

"Arnold and his crew were great to work with. We appreciated the quality of the work, the creative problem solving, and the willingness to make changes, sometimes last minute to accommodate our vision for our forever home. Arnold provided invaluable advice during the design and construction phases that allowed the project to move smoothly especially considering we both worked out of town during the week."


“It was a great pleasure working with Arnold and his dedicated team renovating our basement. From start to finish, Arnold’s extensive knowledge made the entire experience a breeze. We were very pleased with the quality, proficiency and skill that went into making the basement one of our favourite spaces in the house.”
