Take a look at what some of our customers have to say!

Solid company and great experience from beginning of the process to the end. Ordering and getting quotes with Kelii was professional and had a faster turnaround than expected. The install crew of Paamai, Grant and Isaiah finished my house in a day (6 windows).  Would highly recommend.

— Jarrett M.

A shout out to  John Rice and Kaiona who did an excellent installation of doors and windows for us. We are very pleased and impressed with Diamond Head Windows and Doors. A completely professional experience for us.

— Dennis M.

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.

I am over the moon with the service I received from Diamond Head Windows and Doors. From my initial consult with Ryan, to scheduling with Marisa and then the INCREDIBLE install team (thank you Isaiah, Paamai and Grant for truly going above and beyond for my mom!!) I was met with exceptional service and kindness at every juncture. The communication was unmatched, the product is stellar and the price was the most competitive on the island. And once you start shopping for windows and hearing project timelines you will see that Diamond Head's timeline BLEW the competition out of the water. There is no way you will be disappointed if you work with this stellar team. I am so happy with my new windows. Merry Christmas and thank you!

Sean just left our house and did a totally amazing job. We have 4 big windows thar have handles that had rusted out and we couldn't open or shut them. Sean came out after a couple of times trying to get the right pieces, and got them installed. They're like brand new. He was completely friendly and communicated very well with me what the problem was and what needed to be done to fix it. He represented Diamond Head Windows very well, as we've been very satisfied with our windows from them!

Our four windows arrived on-island in mid-Aug and we had them installed over the Labor Day weekend. Overall, I'm pleased with the quality of the white vinyl windows (with white grids) as well as the actual installation. There were a few hiccups but were relatively minor and not even worth mentioning. I would just suggest that customers schedule the install for early morning to ensure the project is completed before nightfall.  The goal obviously would be to start and finish in one day if feasible. At any rate, I'd highly recommend Diamond Head Doors & Windows... shop around and compare, but you'll be pleased with DHW&D.  I've got several more windows to replace and I'll have DHW&D do the work. Mahalo to Mr. Ryan Paul (Sales), Melisa (Install Mgr), and Christian for the actual install.

I just had 20 windows in my house installed by Diamond Head Windows. The crew, led by Stan, were very fast and efficient. They did an awesome job installing the windows in less than 2 full days!  Everyone was courteous, respectful of my home (taking off their shoes and wearing socks in my house), and wore face masks, which was my preference. The Leahi windows are beautiful, and really upgrade my home. From the inside of my house, it looks like the windows and screens aren't even there!

Brenden, the sales consultant was also awesome. During the initial consultation, he patiently explained and showed me the properties of the windows and screens, and walked thru my home twice, to give me an accurate estimate. He spent almost 3 hours during the first visit. He was always available to answer my questions.

— Debbie I.

Great product. Great service. Installer, Jacob, is very friendly and thorough, and installation was quick. Everyone is pleasant and polite.

— John P.

I had a great experience at Diamond Head Windows after many weeks of going back and forth with multiple companies I finally decided with them. The lady who came out was very nice and helped me with all my questions and made good recommendations. The installers were so nice they even helped me put up a rod I needed help with. My home looks so much better now that I got rid of those old jalousies! I am happy I went with them, the wait was worth it. I would recommend.

— Jennifer S.

I had several windows replaced in my home this week by Diamond Head Windows and Doors. I am soooooooooo pleased and would highly recommend them. I have plantations shutters in all my windows and they were so careful not to disturb them. The crew was David and Damon and they were very skilled, knowledgeable, respectful, and amazing. I do not have enough positive comments for them. This is one of the few times I did not have to repair something else after having a job done. I am really happy with the beautiful windows -- they are such high quality and enhance my home. Mahalo nui!!!!

— Stacey K.

Diamond Head Windows & Doors is known to be one of the best window dealers on the island. The sales team is very knowledgeable and easy to work with - and they have some of the best installers. They come across as a partner in making an informed purchase decision. Highly recommend!

— Bob J.

Wonderful people and company to work with. Quality windows and in compliance with HOA guidelines for our condo. They came early and cleaned up really well after work. Recommended!

— Patricia J.

We shopped around. Diamond Head Windows had the best products, installations and by far the best warranty. Our 27 windows were installed in 3 days and we could not be more satisfied. The owner had more window knowledge than all the other companies combined.

— Gale D.

The entire crew of Diamond Head Windows & Doors is made up of exceptional workers using exceptional products. They absolutely stand behind their guarantee; John Rice just came by to check on a locking mechanism. He was professional and prompt. His visit exemplified this company’s trustworthiness.

— L.L.

Quality products, fair prices, the best warranties and great service. If you do your research, there’s really no comparison!

— Todd M.

— Makoto M.

If you need new energy efficient windows, this is the place to go! I love my new windows! I highly recommend Diamond Head Windows and would totally refer them to my friends and family. You will not be disappointed. Excellent customer service and the product is amazing.

— A.F.

A totally great company, from the first minute of the estimate through the installation! What a pleasant experience to see such competent, courteous, and professional business people. Cleaned up beautifully, consulted me along the way, explained how everything works… what more could I ask?

— Ginny M.

Very happy with our windows and lanai doors from Diamond Head Windows. The whole process was great. Makes such a difference keeping our house cooler.

— Andrea I.

Great experience from start to finish. They delivered on all of what they said the new windows would provide - heat reduction, noise reduction and most of all, they look fantastic. The only thing we would do differently is get them sooner.

— Gabe S.

My experience with Diamond Head Windows and Doors was outstanding. Everyone was very friendly and helpful. The installation team was by far the most exceptional team of guys we have ever worked with. They did a wonderful job and left our home and property clean and took away all debris. I highly recommend this company!

— Tonya T.

These guys are on top of it! I have tried many window suppliers in the past but always have experienced some issues during the process. Want to thank the team for making the window and door installation process seamless. If you're looking for an expert window supplier here in Hawaii give the team at Diamond Head Windows & Doors a call!

— Thomas P.

John Rice came out to repair the screen on a sliding patio door and a window screen last week. He was on time, professional, courteous, and did a great job. Great Customer service is hard to come by these days. John represented Diamond Head Windows very well. Thank you.

— Gloria A.

Installers Jacob and Eric did an exceptional job. They were prompt, polite and respectful of our home. They were neat and cleaned up the work area spotless. Our previous windows left our drywall damaged. Jacob cleaned it up and touched it up really nice. They did a beautiful job!

— Robyn I.

We can't be more pleased with everyone at Diamond Head Windows & Doors. We had several estimates but no other company spent the time helping us resolve our issues. Now that the job is complete, we are amazed at how smooth the process went. We love our windows. My husband and I highly recommend them.
