What do recent reviews say?

From roof replacement to siding overhauls, customers report consistent excellence in workmanship and unusual attention to detail. Ruben, Oscar, and team arrive on schedule, finish faster than expected (jobs often in one day), take before-and-after photos, clean up thoroughly, and communicate proactively. They stand behind their work with warranties that extend ten years or more, adjust scope if work turns out unnecessary, and show up unscheduled to fix minor issues long after a job closes. One reviewer mentioned being told late of an estimate cancellation, but 48 of 49 reviews describe reliable, professional service.

Leaders in the crew earn mention by name across dozens of reviews, a sign of repeat business and trust. The company takes on complex diagnostics (basement leaks, insulation gaps) and explains reasoning in detail. Customers feel heard, not pressured, and often return for follow-up work on gutters, inspections, or new projects. Service spans flat-roof rebuilds, metal work, siding of multiple materials, chimney repair, and gutter replacement, making them a one-stop exterior shop.
