But growth had stayed by its side as Drainage Division was added into the line in 1987.

In 1990, Electrolux Services acquired Thomas Cowan and Cleaning Division was added to complement existing services.
When Environmental Services (ESGO) acquired all AB Electrolux' s cleaning and commercial service activities in Asia and the Middle East (03 April 1992), it further strengthens the mission of Thomas Cowan to provide comprehensive " Package Deal" services i.e. Cleaning, Pest Control and Drainage Works.
