Often I enter premises where an invisible wall is present in the form of odors that literally tell me that their are pets within the property. In addition, nicotine smoke and fire smoke, food smells can be initially cleaned and neutralized.
At Eco Extreme Clean we have at our disposal professional products that enable us to kill outright these pet associated smells.
Not only can we kill the smell, we can neutralize the air in the property, We also can coat the walls with an invisible film which will seal in the smell into the wall. (Afterwards one can still decorate over the surfaces.)
