Denzel Environmental Services eased our sudden burden of needing asbestos pipe insulation removed ASAP to repair leaking steam pipe.
At initial consult, Carlos gave us copies of Massachusetts State Abestos License Number and Certificate of Liability Insurance. He explained all the details involved in a safe asbestos removal process.
On removal day, Carlos and crew arrived punctually and worked nonstop, removing the asbestos pipe covering. They finished the job with an immaculate cleanup.
We highly commend Denzel Environmental Services for a professional, well done job. Carlos is an extremely conscientious liaison person, returning all calls and texts promptly. The whole process was facilitated smoothly making it a very satisfying experience. We would definitely use Denzel Environmental Services again, if needed.

We recently used Denzel Environmental Services “AGAIN” for asbestos pipe insulation removal after a very positive first time experience several years ago. As before, Carlos was conscientious in guiding us through the necessary steps starting with touching base with MA state inspector and to final inspection by 3rd party company that checks that the job was done correctly and safely. Carlos and his team are prompt, courteous, and do a super clean up. Their competence and accountability are very reassuring to us. We appreciate their professionalism.
