I have known Pedro Lemus, the original owner, for forever. Sound by Design is helpful, honest, prompt, thorough in bids, and does exactly as promised.This was my first time using them for such a big job and working with their new partner, Paul. I was very happy. They installed a completely new system and repaired an old system. I continue to use their service because they know it. I would tell a potential customer that they are honest, come when they say they are going to come, personable, and prompt. They also explain very well.
