Rywen Insulation Inc, a family-owned rodent exclusion and insulation contractor based in San Leandro, California, is drawing attention to a detail that often escapes homeowners attempting to keep rodents out of their homes: the size of the openings involved. A rat can fit through a gap about the size of a half dollar, and a mouse can pass through one about the size of a quarter. Because those openings are usually too small to see from the ground, the entry points that allow rodents inside frequently go unnoticed until insulation damage appears.

Rywen Insulation Inc provides rodent proofing and rodent exclusion for homeowners in San Leandro, Oakland, Berkeley, Alameda, Hayward, Castro Valley and across the East Bay. The company can be reached at Rywen Insulation Inc, 456 Hester St, San Leandro, California 94577, (415) 770-0342, rywenusa.com. Rywen Insulation Inc operates under California contractor license #1140414 (C-2 Insulation).

The focus on small openings reflects how the company approaches its work. Rywen Insulation rodent proofing in the East Bay is structural, meaning the emphasis is on sealing the building rather than managing animals after they enter. The company is a structural exclusion contractor, not a pest control company, and does not use poison, bait stations or traps.

"People look up at the roofline and assume everything is closed, but the gaps that let rodents in are often no wider than a coin," said Roni Galicia, Owner of Rywen Insulation Inc. "The job is to find every one of those openings and seal the building so the problem does not come back."

The process begins with a free inspection of the attic and crawl space, including photo documentation of every active and potential entry point. Those openings tend to cluster at the roofline, fascia, open roof returns, soffits, gable and dormer vents, the chimney chase, foundation vents, crawl space access openings, the garage door perimeter, and pipe, cable and duct penetrations. Each opening is sealed with galvanized steel mesh, sheet metal and rodent-rated materials. Contaminated insulation is then removed and affected surfaces are sanitized, with new insulation installed after the exclusion work is confirmed. A crew returns about one week later to confirm there is no further activity.

The company provides same-day written estimates and uses in-house crews rather than subcontractors. Related work often follows the exclusion process, including attic cleaning and sanitizing, insulation removal, attic insulation, crawl space insulation, crawl space encapsulation, and crawl space moisture barrier and vapor barrier installation.

"Insulation is usually where the damage shows up first, so sealing and restoring go hand in hand," Galicia said. "Confirming the work with a follow-up visit is part of how the crew keeps a home sealed over time."

Rywen Insulation Inc is a family-owned company serving the East Bay from San Leandro. The company specializes in home insulation and structural rodent exclusion, along with attic and crawl space cleanup, encapsulation, and moisture barrier services, with the goal of making homes safer, more comfortable and more energy efficient.
