Rodent Proofing & Pest Exclusion
in Guildford, BC
Guildford is one of Surrey's established suburban centres, with residential development that began in earnest in the late 1960s and continued through the 1980s. The housing in the Guildford town centre area and the surrounding streets is primarily from this era — single-family homes and townhouses built on crawlspace foundations with the standard vented-crawlspace approach of the time. The relatively flat terrain in the immediate Guildford area means that drainage here depends on proper grading and functioning storm infrastructure rather than topographic relief.
Rodents find crawlspaces attractive for the same reasons moisture does well there: it's dark, protected, relatively warm, and — in homes without proper exclusion — easy to get into. Rats (particularly Norway rats, common throughout Surrey and the Fraser Valley) and house mice can squeeze through gaps as small as a quarter-inch. They enter through uncapped foundation vents, gaps around utility penetrations, deteriorated sill plate joints, and even through the condenser lines of HVAC systems if protective screens are missing or corroded.
Our rodent-proofing process starts with a perimeter audit: we walk the exterior of the foundation looking for every possible entry point, then we move inside the crawlspace to identify any gaps that weren't visible from outside. Foundation vents are fitted with heavy-gauge galvanized steel mesh or replaced with sealed covers. Gaps around plumbing and electrical penetrations are packed with stainless steel wool and sealed with caulk or foam. Damaged sill plates are repaired. If the foundation vent openings are large or irregularly shaped, we use pre-formed steel exclusion panels rather than flexible mesh, which rodents can push past over time.

About Guildford — What We See Here
One characteristic of Guildford's housing stock that we note is the prevalence of original fibreglass batt insulation that was installed between floor joists and has never been replaced. In homes of this age, that insulation has had 40 to 50 years of Pacific Northwest wet seasons cycling through the crawlspace, and it has almost universally failed as a thermal product. Replacement with modern waterproof insulation options is a common scope element when we work in this area, always preceded by addressing the moisture conditions that destroyed the original material.
