"Outstanding customer service from start to finish! I extend my thanks to Ryan, the operations manager, for going above and beyond to make sure my order arrived in a timely manner. I also appreciate the professionalism of the install crew, Paamai and Isaiah. I have used three different window companies over the past two years, and I have settled on Diamond Head Windows & Doors for all future projects. The company is reliable and efficient, and I recommend them to anyone interested in window and door installation services."

"This is my second review for Daimond Head Windows. First review was for my 16 widows and sliding door which Stan and crew did a fabulous job. My second review is for my Security Door. John Rice and Kaiona did a fabulous job fitting and rebuilding door frame to fit my door perfectly. Earlier there was a problem with the door not fitting (wrong door) John went back to the shop and had remedied the problem by switching my door out with another door that fits (correct door). The first door also had no keys. I am so happy that John was able to remedy the problem and save the company any future complaint from me. Give them a call, you won't regret it."

"We were very happy with the entire process, from start to finish. We moved into our new house and immediately needed to replace 2 sets of oversized sliding glass doors that made it impossible to keep our house cool. Brendan came and helped us pick out what we needed, gave us estimates and quoted timelines. Everything happened exactly as described and we even got the doors installed a week ahead of the predicted timeline. Paamai and Grant came out to install both sets of doors and were fantastic, they were on time, very professional, and did an excellent job. The doors are exactly what we hoped for and we will be returning to Diamond Head Windows when we are ready to replace the rest of our doors and windows."

"We previously had four large windows installed late last year, and had the remaining six windows installed this week. The quality of the sliding vinyl windows is excellent. Am very pleased with their function and how they look. It's a nice upgrade and adds value to the house. We are especially pleased with the efficiency and professionalism of the entire crew... starting with Ryan who came to the house for the initial consult, to Marisa (Ops Mgr) who organized everything, to the four wonderful installers... Isaiah, Grant, Nate, and Sefo. If you are thinking about getting new windows in your house, give them a call. You'll be glad you did. Fifty percent down when signing the contract, with the balance due at installment. Depending on window availability, it may take several months to get the windows if the order has to be shipped from the mainland. It's worth the wait..."
