Brian is a friendly and helpful contractor. We feel that a great personality is often a cornerstone of a great contractor. Brian helped us source a good window product, quoted the job, and ordered with our minimal assistance. The install took one day with only one small problem removing an old window - which he fixed. The work was done in the summer of 2007, and we haven't had any problems with the install since (now: March 2008), plus a portion of the work qualified for the ontario home energy grant problem.
