We have a home in Toronto that was built in the 1940s. The hot water pipes from our boiler had insulation wrap on them that was asbestos. I called Green Stream and they came a few days later to remediate/remove it. They did a great job. They wore protective equipment, and cleaned up as if they were never here. Polite, prompt, and explained everything. I found the price very fair considering what they are dealing with. Very satisfied.
