What Richmond Hill homeowners say
Honest about what I did not need
They told me the flue did not need sweeping yet and charged only for the inspection. First contractor in years to talk me out of spending money.
Clean, quiet, respectful
Shoe covers, sheeting, and a sealed vacuum. My wife works from home and barely noticed they were here.
Post-fire inspection
Small flue fire in January. They inspected, documented the damage, and coordinated the report with my insurer without me chasing anyone.
Great with an old masonry chimney
1920s brick, plenty of quirks. The technician clearly knew older builds and pointed out mortar joints to watch rather than pushing a rebuild.
