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!

They need to paint the trim on all windows that were recaulked since white caulk was unevenly spread onto the blue trim. They showed up on time with an apology gift from Chun Wah Kam. . They are cleaning and repainting the window trim as I'm writing this. Happy since we just had the house repainted 4 years ago. I originally chose this company for the lifetime guarantee and quality of these windows. We do love the windows for the past 9 years. Great at blocking out sound and maintaining air conditioning temperatures. It was news to me that the company changed ownership. I'm glad the current owner is honoring the warranty and knew the previous owners personally.

They explained that the door is made on the Mainland, it is custom made to fit my door frame, and may take 2+ months.
