What London homeowners say
Clean, quiet, respectful
Shoe covers, sheeting, and a sealed vacuum. My wife works from home and barely noticed they were here.
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.
Fast after a smoke back-up
Smoke came into the living room on a Sunday evening. They were here the next morning, found a nest, cleared it, and tested the draft before leaving.
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.
