Attic Bros

Attic Bros holds a perfect 5.0-star rating across 19 client reviews in San Ramon, California. This insulation contractor serves homeowners throughout the Tri-Valley region, addressing issues that stem from damaged or insufficient insulation in attics, crawl spaces, and garages. Clients consistently mention the team's punctuality, clear communication before appointments, and thorough approach to identifying and sealing entry points that allow pests and drafts to infiltrate homes. The company operates Monday through Friday from 8 AM to 5 PM, and the reviews indicate they handle both planned projects and urgent situations requiring follow-up visits.

What distinguishes Attic Bros from typical insulation contractors is their comprehensive remediation approach. Rather than simply installing new insulation, they systematically seal every access point leading into the crawl space and under-floor areas, then sanitize the affected spaces before reinstalling insulation. Multiple reviewers specifically mention this methodical process, noting that technicians returned to complete additional sealing work after the initial service. The company also handles the aftermath of rodent infestations, combining cleanup, sanitization, and insulation replacement in a single service package.

One homeowner described how technicians Jesus and his team sealed all entry points to both the house and crawl space after rats had destroyed existing insulation. Another client recounted how Ricardo made a follow-up visit to close remaining exterior entry points. A third reviewer praised Justine for ensuring every reported issue was communicated to the crew in advance. These named technicians exemplify the coordinated, detail-oriented service that generated the company's perfect rating. The workers who came were cordial, efficient, and accommodating, according to multiple reviewers.
