Your home is as special and unique as you are.

Choosing the highest-quality windows and doors will enhance your lifestyle and add to the value, security and beauty of your residential or commercial property.

We are a locally owned, second-generation family business serving Hawaii since 1990. Windows and doors are all we specialize in, and we are continually refining our innovative design and engineering processes to ensure long-lasting, trouble-free performance. Our custom windows and doors go beyond the standard sizes, colors and style selections to meet your exact needs, specifications and preferences.

As Hawaii homeowners ourselves, we understand the islands’ unique environmental challenges. These same windows and doors that we manufacture are in our homes too, and we stand by their superior quality.

At Coastal Windows, we treat you like family. Welcome to our ‘ohana. Come visit our showroom and manufacturing facility to see firsthand our commitment to excellent craftsmanship. We invite you to experience the Coastal Windows difference, and we look forward to serving you.
