Mario responded very quickly and showed up promptly for a routine inspection required for our home insurance renewal. Thanks to his thoroughness, we were not only able to renew our policy after submitting his report, but he also fixed a leak in the water heater that would have otherwise gone unnoticed, as well as a clogged kitchen drain. Overall, his professionalism and attention to detail made the entire process smooth and stress-free
