Rodent exclusion that closes the house for good

A full-structure entry survey, then sealing every opening rodents can use: attic and foundation vents screened in hardware cloth, roofline and roof-return gaps closed in metal, pipe and cable penetrations sealed, door sweeps and garage seals fitted, and weep screeds protected without blocking their drainage.

In Los Angeles, yes, and that timing is actually the cheap version of the job. The neighborhood roof rat population is permanent; sealing before they move in costs the exclusion alone, while sealing after adds trapping, and often cleanup, to the bill.

No. Vents get screened, not blocked: quarter-inch galvanized hardware cloth keeps rodents out while passing the same airflow. Anything that must stay open for code or drainage gets protected with purpose-made guards instead of sealant.

The materials are the point: galvanized mesh, sheet metal and rated sealants rather than foam and screen scraps, so the work holds for years. The weak point over time is new penetrations, a solar run, a new cable line, which is why the report maps what was sealed so future work does not quietly reopen the house.

We stand behind the sealed points, and if rodents reopen or bypass covered work, we come back. What no honest company guarantees is the whole future of a structure that keeps changing; what you get is every current entry closed, documented, and warrantied work on the sealing itself.
