Last year we met with a client who had their landscape contractor install their lights five years prior. When we met, more than half their lighting system wasn’t working.
After calling the contractor who originally installed their system, several times, he finally came out to repair their lighting system. He spent the better part of 8 hours trying to fix their system, but couldn’t figure out what was wrong. He told them that he wasn’t sure what the issue was but would give someone a call and return later. They never saw him again, and their subsequent calls and voicemails to him all went unanswered.
Moral of the story: if you hire someone to install your landscape lighting, you should feel assured that they can confidently service your system if something happens.
