Visit our Showroom

Witnessing our custom-manufacturing process in person will make you a believer in the Coastal Windows difference. We invite you to visit our factory showroom to see our complete line of artfully handcrafted vinyl window and door products, designed and manufactured on-site in our Waipio facility.  

E komo mai. Our doors are open to everyone. We welcome architects, builders, contractors, designers, and homeowners to learn about our innovative engineering standards, commitment to our island community, and exceptional customer service. Come experience the difference for yourself.

Factory Tours

Interested in going behind-the-scenes? As Hawaii’s only local vinyl window and door manufacturer, we invite you to join us for the unique opportunity to tour our 30,000 sq. ft. manufacturing facility in Waipio, view the manufacturing process from start to finish, and come meet the people who build them. Our BIG Factory Tour Events are held twice a year in January and August. You can also ask your Coastal Representative to schedule an individual mini-tour anytime throughout the year.

Please call (808) 676-0529 or email to schedule your visit and get a special, up-close tour to see the Coastal difference for yourself!

Tours are free. Appropriate footwear is necessary – visitors must wear closed-toe shoes. Children under the age of 12 are not permitted for safety reasons.
