We had a fence installed recently and although it appears to be installed correctly only time will tell. I'm skeptical because their attention and concern for your property is non-existent. After being here for only 60 seconds, they cut our cable line, which was marked by the cable company. When we asked them about it, their answer was "we may have cut it." A few months later we turn on our sprinkler system and find that they've cut that line too. They just want to get the job done to get your money.
