Most people see an old house waiting to be demolished and think:
“Just tear it down.”
What they don’t see is everything that has to happen first to do it safely and legally.
This house contained asbestos duct insulation and asbestos-containing texture over plaster. Because of the materials involved, this became a Class I asbestos removal project requiring a full containment, negative air pressure, and a three-stage decontamination unit.
In these photos, you’ll see the manometer monitoring the containment pressure. That’s how we verify the containment stays under negative pressure so asbestos fibers remain inside the work area and do not migrate outside the containment.
The process is dirty, physically demanding, and extremely labor intensive. There’s nothing glamorous about crawling through old houses in respirators and Tyvek suits for hours at a time.
But there is something satisfying about doing the job the right way.
By the end of final cleaning, the structure is often cleaner than it has been in decades — and ready for the next phase safely.
This is the part of demolition most people never see.
22 years in business has taught us that environmental work isn’t about shortcuts.
It’s about discipline, training, containment, and protecting people.
