Hell Pit Access and Exclusion in Port Coquitlam
older Oxford and Mary Hill sub-floor voids

Yes, as part of a comprehensive pest inspection on a 1940s to 1950s property in Oxford. Pre-standard construction era homes in Port Coquitlam occasionally include sub-floor access areas from original plumbing infrastructure.

Yes. Sealed sub-floor access voids in older Oxford or Mary Hill construction may contain accumulated moisture damage, pest nesting, or deteriorated drainage infrastructure. Knowing the condition before building over it is more cost-effective than future discovery.

Possibly. When standard crawl-space inspection does not fully account for documented rodent activity near the Pitt River, a sub-floor access void provides an alternative staging area. We check for sub-floor access when the crawl inspection does not explain the full picture.

Metal-framed access hatch that allows future inspection but prevents pest entry — rodent-grade mesh at any sub-floor to exterior connection, perimeter caulking at foundation gaps.

No. Cedar Hills, newer development, and post-1960s construction throughout Port Coquitlam does not carry this construction type. This is specific to the oldest Oxford and Mary Hill properties.

Rare compared to older Metro Vancouver cities like Vancouver or North Burnaby. Some older Oxford and Mary Hill properties from pre-1960 construction may have sub-floor access areas. Most Port Coquitlam homeowners will not encounter this situation.

Yes. Renovation is the ideal time — when flooring is already removed, access requires no additional deconstruction.

BC's wet climate and proximity to the Pitt River in Oxford properties means any near-grade sub-floor void carries above-average moisture. Moisture readings are particularly important during assessment on these properties.
