G.C. Environmental, Inc.

G.C. Environmental, Inc. (GCE) is a full service Environmental and Mechanical Service Company, providing cost-effective turnkey services for boiler conversion, tank and related environmental needs.  One of the most expensive tasks during conversion from No. 6 fuel could be the cost of replacing your tank.  GCE has the experience to evaluate your tank and possibly offer a repair solution, if necessary.  With an upgraded tank and proper boiler service from GCE, your boiler may continue in service with ULS 2 fuel oil for many years to come. Turnkey boiler conversion and replacement services are also available including all permitting.  Services for Clean Heat buildings include:

  • GCE can fiberglass line your tank with a 10 year warranty or weld a new bottom, which is far less intrusive and more economical than replacement.
