"This is the review. Let me know this is good before I send Prompt and on time service for the asbestos removal along with safe and proper poly containment. Also 3rd party testing confirmed safe air test. The workers were in suits, masks and had ASD machines running very professional and highly recommended for any asbestos work! We are very pleased the cleanup was nice, with no debris . I would definitely hire again if needed"
