About Us


If you suspect your home or business has asbestos that you intend to disturb, make sure call trained professionals for testing first.

Worker Carrying Asbestos Board

Asbestos Abatement

CES is licensed to safety remove and dispose of insulation on pipes and ducts, floor and ceiling tiles, transite roofs and siding and other asbestos containing building materials.


Lead Abatement

Many structures build before 1950 and some built as late as 1978 contain heavily leaded paint. As lead paint ages tiny pieces may peel or chip off and can be dangerous if ingested.


Demolition Services

Our team of experienced employees will carry out both small and large demolition projects – either partial or complete demolition.


Mold Removal

Due to increased health, safety and liability issues about the adverse effects of mold, many new techniques have been developed to deal with these problems.
