Tweet/Garot is committed to Green Building ideals and the sustainability of both existing buildings and new structures. The sustainable methods we use decrease project costs over the life of the building through reduced energy consumption, reduced maintenance costs, improved health of building occupants and increased occupant productivity.

“Mechanical contracting, by its nature, leaves a huge footprint on our natural resources,” said Tweet/Garot CEO Timothy J. Howald. “We're experimenting by trying different things and expanding our knowledge so we continue to be innovative and environmentally responsible. We feel that as one of the largest contracting companies in Wisconsin we have the ability to set the example as it relates to sustainable initiatives and environmental stewardship.”

Sustainable Practices:

•We employ shop and job site recycling programs

• We have numerous LEED Accredited Professionals on staff, utilizing their vast green expertise
