Today’s hardwood finishes are much safer than they were 10 years ago. SOEN hardwood uses hardwood finishes that are either 100% VOC free and low VOC finishes that are approved to be used in hospitals and schools. Any hardwood finish we offer or use will be environmentally friendly and have 0% off gassing. This is especially true for penetrating oil finishes. There are a handful of water based finishes that will be 0% VOC, so before you commit to your hardwood refinishing process ask your Denver contractor about finishes and have them walk you through all the available finish options. Your hardwood refinishing process should not introduce VOC gasses in your home, which some of them cause cancer.
