What Woodstock homeowners say

Second flue done same visit

Old house with a furnace flue as well. They handled both in one visit and discounted the second one rather than charging full price twice.

Level 2 for a house sale

Recorded the whole flue on video for the buyer's agent. The chimney line item stopped being a negotiation point the same day.

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.

Owen C. · 2025-11-08

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.
