My daughter works in a lab in Guelph and I live near Peterborough. I found a number of companies on the internet and called to check about making an appointment on a fixed day since the condo is currently rented out and timing was critical. Brian was the only to do me the courtesy of returning my call. He took all my particulars, gave me a range of possible issues and their costs, and worked out a time that worked for everyone. Tim arrived as promised and quickly came to a probable cause. He quickly eliminated all other possibilities and once things started to be opened up the problems were obvious. He called a supplier, got a replacement unit, installed everything, and was done in under three hours from first coming through the door. I found him to be personable, knowledgable, thorough, and proudly professional. When it comes to remodelling and renovation we have his card.
