About Rywen
Built on a Family Name. Run to a Higher Standard.
Rywen Insulation is a family-owned company run by Roni Galicia and his brothers. Every technician is hired, trained, and managed in-house. No subcontractors. No strangers in your attic. Just the same team from your first inspection to your final warranty.
A Contractor Built on Trust, Not Turnover
Rywen Insulation was founded by Roni Galicia, who started doing insulation work across the Bay Area before formally incorporating in 2025. What set Rywen apart from day one was simple: Roni refused to hire subcontractors.
Every crew member at Rywen is trained by Roni personally. They learn the materials, the installation standards, and the follow-up process. That consistency is why Rywen has earned over 100 five-star reviews in a short time and why clients refer their neighbors.
The business is headquartered in San Leandro and serves the greater Bay Area, from Oakland and Berkeley to the Tri-Valley and beyond.
- Family-owned and operated since 2020

How We Work
The Rywen Standard
Four practices that separate a Rywen job from every other contractor you have called. If you are weighing bids, here are five red flags to watch for when hiring an insulation contractor.
No Subcontractors, Ever
Every technician is a direct Rywen employee. You get the same trained crew from inspection through installation, not whoever is available from a temp agency.
Inspection Before Recommendation
We spend 40-60 minutes in your attic or crawl space before suggesting anything. Our estimates are based on what we actually find, not a phone call guess.
We Come Back After the Job
Every project includes a follow-up inspection 7 days after completion. We confirm the work holds, issue your warranty paperwork, and close the loop.
Photo Documentation on Every Job
We photograph your space before and after every project. You know exactly what was done and why – no ambiguity about what changed.
