About Us

Why Montage Décor?

Founded in 2005. Montage Décor was the vision of Gavin Ishikawa. Born and raised in a construction family, Gavin saw the passion that his father had when revealing a finished project to the homeowner. From the beginning, Gavin has been instilling a philosophy of excellence with an unrelenting approach to detail. He expects to deliver the highest quality product whether we are remodeling your bathroom or building a custom multimillion-dollar home. In 2018, we added companies such as John Cook Kitchens and Infinity Design and Supply so that we can by your one stop shop for service and convenience. We have a dedicated team ready to assist you.
