What Komoka 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.
Good work, tight scheduling
Had to move my appointment once, but the sweep itself was excellent and the crown sealing has held through the winter with no water staining.
Camera scan caught a cracked tile
Previous company swept and said everything was fine. Diamond ran a camera and showed me a cracked liner tile on screen. Glad I got the second opinion.
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.
