Silva's Concrete & Interlocking

I dealt with the owner Ernesto who was nice enough. His crew did good work and I was relatively satisfied. Unfortunately when I tried to get him back 11 months later to fix something very minor he just kept putting me off. His contract clearly states that "Job guaranteed for one year". Doesn't seem like he honours this guarantee. I have called and spoken to him 4 times and still hasn't shown up to repair the minor issue.
