Hi all, I'm new to this site and have already found a lot of useful information. I recently had a call from a management company that I have several snow removal contracts with. They've asked me to put an estimate together for a condo project. I have no information other than the square footage. They're looking for a design fee price and a estimated install. I don't have a problem with the design pricing but does anyone have a general idea of a cost per/sqft. New install with existing tap on a obsolete 30+ year old system.
