Here at Colonial, the health and well-being of our employees and our clients is top priority to us. As the world is in protection mode, we too are making strides to prevent the spread of the Coronavirus. Sanitation practices throughout our locations has been ongoing and our employees suit up in brand new hazmat suits with the best respirators in the business. Any employee with a sign of fever, chills or cold is asked to stay home.

When insulating your home, the installers are now approaching clients suited up, to rest everyone's minds at ease and continue the insulation work without worry of spreading germs. Prayers go out to everyone affected by this terrible virus and please support small business as much as possible during these difficult times.
