K Guard leaf Free Gutter Systems. Were sold by someone with K Guard who then passes it off to a contractor who installs it. Which they did in May 2012. Leaves clogged up in one corner of the front gutter (so much for leaf free) but went unnoticed for a while. Even though the contract says they will come and clean the gutters as necessary for free, I unclogged it and water now went down the down spout. In july 2014 the salesman no longer with the company I called PT and left a message. Then sent an e-mail - unanswered. Wanted them to inspect the system, unclog as necessary and reroute a front down spout to have water flow away from basement wall. Had a call back that someone would be here last Monday or Tuesday. Nobody showed. Finally I sent an e-mail expressing my displeasure in follow up and telling them they are not permitted on site to do any work at my address. I hired someone to come and do the work they would have gotten, plus look at the system and clean it as necessary. If this system is supposed to be leaf free as advertised yet clogs with leaves it my not be worth the money I spent if iI have to get it cleaned out anyway. Secondly however no follow up of a satisfactory level from PT was disappointing but apparently standard with most companies. The warranty says it will remain clog free as long as it is on your house but if it does clog they will come and unclog free of charge. Not worth the paper it is written on if they don't show. installation they were great so if you go with them their work is good and installers nice. Just beware of followup. It may not happen. I gave a 6 rating based on installation. They lost points with no attention to customer service.
