What Hensall homeowners say

Raccoon eviction and cap fitted

Family of raccoons in the flue. They removed them humanely, cleaned everything, and fitted a stainless guard that has kept them out since.

Alicia D. · 2026-02-25

Report my insurer accepted

Needed dated documentation for renewal. The report had the technician certification number and photos, and my insurer accepted it without a follow-up question.

Thorough sweep before the season

Drop cloths went down before anything else. Room was spotless afterwards and they fixed a loose cap on the spot rather than booking a second visit.

Post-fire inspection

Small flue fire in January. They inspected, documented the damage, and coordinated the report with my insurer without me chasing anyone.
