The house was build in 1938,some of the electrical wires were routed under heating ducts in between the wires and ducts there is some insulation to protect wires from heat.This insulation is like a grey board about 1/4 inch thick and 12' by 18'[3 pieces] i suspect this insulation contains asbestos Ilive in the Ottawa (ON) area who should i call to remove this safely considering this is what looks like a small job.
Answer:
The insulation you describe is asbestos and any good contractor will remove it. This is not a DIY project because asbestos has to be treated specially because of the health hazard it poses.
