Our Company
Kolostat is a fully integrated mechanical contractor in the industrial and commercial HVAC fields with offices in Montreal and Toronto, delivering projects around the world.
From our beginning as a heating contractor in 1927, Kolostat has evolved into a multidisciplinary team specializing in the design-build of projects in building mechanics and industrial HVAC systems, multi-residential and commercial sectors. Kolostat Inc. provides innovative expertise to owners and managers looking to improve the infrastructure and energy efficiency of their buildings. In November 2022, Kolostat inc. and Krome merged to form a single entity with very complementary expertise. The offices are in Laval, Montreal and Toronto, and the company carries out projects across Canada.
Depending on whether your project is in the industrial or commercial sector, the scope of our design-build engineering services is customized to suit your needs, your business objectives and your financial criteria. Our world-class design-build engineering cover greenhouse gas reduction projects, whether for new construction, major renovation or retrofit of existing infrastructures.
