Cumaru in San Marino

Cumaru is the answer for 60% of our projects. It's harder than oak, denser than mahogany, naturally insect- and decay-resistant, and finishes with a glassine grain that catches the LA light. It costs about half what Ipe does and lasts about half as long — but 25–35 years is a long time, and most homeowners aren't planning past that horizon. For premium hardwood at a price that doesn't require an estate budget, Cumaru is the answer. Cumaru is an excellent fit for San Marino's coastal microclimate — its high salt tolerance handles the salt-fog exposure without compromise.
