Structural Exclusion

We seal entry points using galvanized metal mesh as a structural backer, followed by mortar, metal flashing, or professional-grade sealants appropriate to the specific surface and opening. Foam is never used — it compresses over time, degrades with moisture and temperature cycling, and rodents chew through it. Our exclusion materials are chosen for permanence, not convenience. The goal is a sealed building envelope that does not require re-treatment.

Entry point mapping is a systematic process, not a visual scan. We trace behavioral evidence — grease marks, gnaw points, droppings, travel patterns — back to the access points that sustain them. We open wall voids, inspect pipe chases and utility penetrations, assess foundation conditions, and evaluate roofline and soffit areas. Where activity is confirmed but access points are not immediately apparent, K9 detection and thermal imaging are used to identify concealed entry and harborage zones.

The exclusion work itself is designed to be permanent — we use materials that do not degrade or fail under normal building conditions. That said, buildings change. New cracks form, pipes get replaced, door seals fail, and renovation work opens new vulnerabilities. We recommend periodic structural monitoring, particularly after construction or significant weather events. Exclusion work addresses conditions as they exist at the time of treatment — ongoing monitoring ensures new vulnerabilities are identified before they become pest access points.
