Our Story

Diamond Head Windows & Doors is Hawaii's premier locally owned windows and door replacement company. We have been humbly serving the island of Oahu since 2012. Our Ohana` has over 30 years of window and door replacement experience.

We believe our strong commitment to local values is what truly sets us apart. We will treat you and your home with the utmost respect (yes, even our installers take off their shoes in your home 😊). Never any pressure; our goal is to always educate you about the best products to fit your needs and budget. Picking the right contractor comes down to trust. Our team will be there every step of the way, earning that trust that has made Diamond Head Windows & Doors into the largest window/door replacement company in Hawaii and voted Best of Hawaii for every year since 2013!

We deeply care about the community in which we serve. Diamond Head Windows & Doors is dedicated to making Hawaii a better place. We are a proud supporter of the Hawaii Food Bank. A portion of every project we work on will be donated to the Food Bank each year.  Hunger should have no place in our local community.

Over the last decade, Diamond Head Windows & Doors has become Oahu’s largest and most trusted locally owned window and door replacement company.

We look forward to having the opportunity to serve you.
