I worked with Preston to request a quote for a bathroom door replacement. The service also required…read morepainting and sealing. During a free on-site assessment, Preston answered all our questions & discussed several options before we decided what we needed. Preston prepared our quote within 24 hours, and the pricing was very fair & reasonable. We needed the door replaced within 4 weeks in preparation for guests, but Preston was able to schedule us within 2 weeks of accepting the quote. Installation day: Preston arrived 10 mins early to set up, and work was handled by Preston, Nick O., and a 3rd worker I didn't get the name of (sorry). All 3 were very professional and friendly. They were also all very patient and nice with our dog who kept barking at them. The doorframe they were working with is nonstandard size and uneven, but they successfully fit a new door without issues and within the schedule. They were self-sufficient and didn't need to ask me many questions or need my help with anything, which made the day really easy for me. The door looks great, fits perfectly, and is super smooth. Extra extra bonus points: They actually left our carport cleaner than when they arrived.... THANK YOU! Very happy & highly recommend. Mahalo, Tatiana & Nick

Mana and his team has walked us through every step of the way from his mobile showroom to the wonderfully clear product. Mana also told me to try and find pricing on his competitors...not even close and not to even sacrifice quality. Unfortunately, we had some busted screens during the process of the home construction, but Kawika (service bruddah) came out checked um, and when he was here I kept asking, what about this one and this one and this one too. He just took them all out, got them repaired and reinstalled them no questions asked. Super Aloha.And this is months after we've been living in the house. Would I recommend....absolutely! Maybe Mana can also throw in a round of golf at OCC as well if you purchase now. Update update, nearly a year later Kawika was very thorough and wanted to ensure our sliding doors were working. He was very tedious and ensured they were installed to the best of his ability. He also noticed walking by some windows that there were some weep holes missing and he offered to fix that too! Kawika accepts tips as snacks are welcome hahaha!

We are now having to resort to legal action. We prepaid the $17K last Sept. 2025 for 3 sliding glass doors and a window. On Sept. 5, Mana told us installation would happen in November. November came and went. Since then we have repeatedly emailed, called and texted both Mana and Paul. We got some response initially, and a promise for delivery in Spring 2026. Spring came and went. We have since been completely ghosted as we have tried to contact them, sometimes daily, asking for an installation date or for a refund. In late July, we sent a letter from a lawyer saying that if we did not receive the materials we have paid for, or a refund within 3 weeks, we would pursue legal action. Unfortunately, this is now what we are forced to do. This company installed windows for us a few years ago and our experience was good. I provided a 5-star rating in 2023. We maintain some hope that Paul and Mana will do the minimally correct thing and deliver the materials we have paid for, or refund our money.

Alex was here every single day. He brought Scott and Anthony with him on different days and I couldn't have been happier with the crew we were given. Every morning we talked about the plan for the day, and what they needed from me. Some days they needed nothing, some days I had decisions to make. The thing I liked the best was I never had to bring anything to Alex's attention. He was on top of everything. Taking a little longer to get a certain window done? Alex told me. A screen needed to be resized and put in, he let me know before I noticed it wasn't there. Or the fact that one of the sliding door screens came in slightly bent. Just enough that you had to be particular about how you closed it all the way.. Alex told ME about the problem. That he already had a new one on order and they would get it handled. I didn't have to find it first a week later and ask to get it replaced. If there was a problem, he already had a solution. And when the typical finishing for the windows wasn't going to work, he took the time to find a solution that came out absolutely stunning. The initial quote and set up process wasn't quite as smooth. I felt like the communication could have been better once we signed the contract. Lack of contact made us a few weeks later in the schedule of getting them installed and that was a bummer. But the actual install couldn't have gone better, and it was meant to be I guess. Window world won't be your cheapest option. But they back their work, they stay until it's finished and the lifetime guarantee on their windows is great peace of mind. I would recommend them a million times over.

I'm glad the current owner is honoring the warranty and knew the previous owners personally.

Craig and his team are clearly skilled at their craft, and made sure to cover up any prior mistakes I had made. I would be hard pressed to believe you would find anyone else with more expertise on island for mirror and glass. From the initial consultation to the final wipe-down, everything was handled with care and precision. They were punctual and professional, timely when communicating.
