I sell and consult about Brazilian hardwood decking, specifically Ipe, Jatoba, Garapa, Cumaru, Tigerwood, Massaranduba and others.   You can call me about you or your customers needs to update, replace or even install Ipe decking or siding.   Ipe is great as it is beautiful, easy to maintain, and will last until your homeowners become sellers.  Actually, after 10 years it will look like it was installed just a few months before.
