Most studios require - and Ellis is pleased to provide - emergency response services, from mold testing, to indoor air, to asbestos removal. Most recently, Ellis managed a $40,000 cleanup of the air supply system of a huge filming stage, following a fire and resultant smoke damage. Other services provided since 1995 include numerous asbestos and lead surveys, abatement projects, soils testing, indoor air quality assessments, and testing of potable water sources.
