Asbestos Removal

Asbestos abatement includes removal, encapsulation, and enclosure of all types of asbestos-containing material. The definitive method of abatement of course is removal. However, under certain circumstances encapsulation and enclosure are options that make sense in certain circumstances. Encapsulation is the process of applying an impermeable barrier or binding agent covering the asbestos that seals it to prevent it from becoming airborne and protecting it from damage. Enclosure is the process, as the name implies, of building a physical barrier to isolate the asbestos from access or damage.


Demolition and Deconstruction, includes the tearing-down of buildings and structures. As a part of our environmental stance we look for opportunities to salvage and recycle what we demolish.

Our clients include building owners, developers, contractors, health care providers, institutions, and manufacturing companies that are committed to providing and maintaining a safe and productive workplace, and residential owners concerned with safety.

Whether you require demolition, asbestos abatement or mold remediation, experienced people are ready to respond.

What is Asbestos?

Asbestos is the name for a group of naturally occurring silicate minerals that can be separated into fiber. The fibers are strong, durable, and resistant to heat and fire. They are also long, thin and flexible, so that they can even be woven into cloth.

Because of these qualities, asbestos has been used in thousands of consumer, industrial, maritime, automotive, scientific and building products. During the twentieth century, some 30 million tons of asbestos were used in industrial sites, homes, schools, shipyards and commercial buildings in the United States.

What is Demolition?

Demolition is the tearing-down of buildings and other structures , the opposite of construction. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for re-use.

For small buildings, such as house, that are only two or three stories high, demolition is a rather simple process. The building is pulled down either manually or mechanically using large hydraulic equipment: elevated work platforms, cranes, excavators or bulldozers. Larger buildings may require the use of a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings. Wrecking balls are especially effective against masonry, but are less easily controlled and often less efficient than other methods. Newer methods may use rotational hydraulic shears and silenced rock-breakers attached to excavators to cut or break through wood, steel, and concrete. The use of shears is especially common when flame cutting would be dangerous.

Avoiding Fines

Avoiding Fines

In late 2011, DEQ fined a Salem building owner and tenant (a church) for improper asbestos abatement methods. Searching the internet will also reveal fines levied over the years against abatement contractors for not using proper work methods. When considering work in the home or in any facility, make sure that proper inspections have been done so you don’t end up wasting money and endangering people’s health. Floor tile, ceiling tile, pipe insulation roofing, popcorn ceiling texture . . . there is a long list of products with asbestos-containing materials.
