We had a new patio and pool, spa and fountain installed about a year ago and already two of the three LED lights in the fountain are not working and some of the caulking between the coping around the pool and the patio needs to be repaired/replaced. Unfortunately it turns out that the guy who did the work is not standing behind his work, so we need a referral to someone who can repair or replace the LED lights in the fountain, and do the recaulking work. Any suggestions for good reputable people who can do this work? Much appreciated.
