Exceptional Work — True Aloha in Every Detail!
We hired Will and his crew at Gundaker Works for a major project: a second-floor addition, a brand-new ADU, and a custom pool — and they absolutely delivered. From day one, their team showed professionalism, skill, and a deep understanding of building in Hawaiʻi. They worked efficiently, respected our property, and communicated clearly through every step.
The second-floor addition blends perfectly with our original home, the ADU is beautifully designed and fully functional, and the pool turned out better than we imagined — perfect for island living. Everything was built solid, with attention to local climate, permits, and energy efficiency.
Mahalo to the whole crew for their hard work and for making this project stress-free. If you want quality craftsmanship and people who truly live and work with aloha, this is the team to call.
