This is in response to the post by Paul Craigen on May 18, 2011. The response is from Condominium First Management Services Ltd. Paul, unfortunately hot water heating systems, commonly used in apartment-style buildings, are extremely susceptible to freezing anytime the outside temperature is close to zero. We are told by the mechanical contractor that this is caused by windows or patio/balcony doors being open at some time before the leak occurs, and they have evidence to support this. As the management company, we take our direction from the board of directors of Canvas at Millrise. It is the board\\\\s decision that the repairs and resultant damage from these types of leaks is the responsibility of the owner of the unit in which the leak occurred. In an effort to prevent these situations, we do send out a notice each fall asking residents to take the proper precautions to avoid ice in the pipes. If you would like to discuss this further, I invite you to call me directly at 403-299-1808. Sincerely, Linda Grey-Martin, General Manager, Condominium First Management Services Ltd.
