Sustainability and Green Construction Montbleau has acquired and maintained the Chain of Custody under the Forest Stewardship Council since 2003. Our company believes that the construction industry can make a significant difference in creating healthier environments within healthier buildings. As part of this initiative we are also members of the US Green Building Council and have worked on LEED certified projects since 2001. We have made sure that FSC certified materials that we handle are kept separate from non-certified or non-controlled material thru this process.
