About Cumaru Decks
Cumaru, commonly known as Brazilian Teak, has earned its reputation as the smart choice for homeowners who want tropical hardwood performance without the premium price of Ipe. This South American hardwood species (Dipteryx odorata) delivers exceptional hardness, natural durability, and beautiful golden-brown coloring that closely resembles genuine teak at a fraction of the cost. For Minnesota homeowners seeking the best value in exotic hardwood decking, Cumaru offers an outstanding combination of performance and affordability.
With a Janka hardness rating of 3,540 lbf, Cumaru approaches Ipe's legendary density while typically costing 20-30% less. The wood's tightly interlocked grain structure provides natural resistance to rot, decay, termites, and marine borers—the same qualities that made teak famous for boat building. Fresh-cut Cumaru displays rich tan to yellowish-brown tones that deepen to a warm reddish-brown as the wood seasons, eventually weathering to silver-gray if left untreated. This color evolution mimics the aging process of genuine teak, making Cumaru an excellent teak alternative.
Our Cumaru installations follow the same exacting standards we apply to all tropical hardwood projects. We source premium FEQ (First European Quality) grade lumber from certified sustainable South American operations, ensuring both quality and environmental responsibility. Installation requires carbide-tipped tooling, pre-drilled pilot holes for every fastener, and marine-grade stainless steel hardware rated for dense tropical species. Proper gapping accommodates seasonal expansion and contraction while maintaining tight, professional joints throughout the deck surface.
