Unfortunately, I had a mixed experience with KNT. On the plus side, the knob and tube was removed and replaced correctly, I assume. The job was done within the estimated time frame (six days). The crew arrived promptly and worked steadily.
However, there was a lack of careful attention to some details. I caught and had corrected the crooked installation of a couple of switch plates, the inconsistent on-off direction of the light switches and the misplacement of a wall fixture (which still ended up slightly off-centre).
Most problematic, though, was damage to the brickwork around the porch light, caused by a large hole cut into the brick to re-accomodate the fixture and the worker's attempt to patch and
mortar afterwards. I then spent considerable time dealing with this unplanned masonry job. I kept KNT informed of the situation, my efforts to get it corrected (three consultations, two quotes) and my expectation that the cost would be deducted from the final amount owing. The repair took seven hours to complete. I did not feel that the inconvenience caused me was understood or appreciated, although an apology was eventually offered.
