Then I met the crew John, Mike and Ziggy. We had a great relationship. Everything that was to be accomplished was explained to me on a daily bases.

"I bought a 105 year old home that has been in my family several generations. I knew I would need a lot of help to update yet preserve this California bungalow. Salvator immediately saw my vision, the houses potential and correct tasks needed to preserve, update, and reliably work on this unique home with the things I needed done. There were almost daily pivots needed and his crew (Emilio, Noe, Henry) rose to each challenge with a way not only to just make it work but also to improve what was already there. Salvator helped me make a few choices with his experience and expertise which worked out amazing. Salvator was the only contractor who recommended things to be done the right way not the cheapest way which would only lead to major and costly problems later. This is my second time working with this group and I would reach out again in an instant if needed. Their craftsmanship and professionalism is worth every penny and that is not always easy to find.

Site drawing detailed how the finished room addition and sun porch would look after the job was completed. Wife and I were completely satisfied with the finished job.
