Our Services
From a single bathroom to a full commercial build, United Construction Group handles the whole job — planning, permits and construction — across all four islands.
Six ways we build with you
Every project runs the same way regardless of size — we look at the site, we go through the plans with you, then we build it. Pick the one closest to what you have in mind.

Five steps, no surprises
-
1
Tell us about the project
Send through what you have in mind. We reply within one business day to work out whether we’re the right fit before anyone commits to anything.
-
2
Site assessment
We come out and look at conditions, access and constraints in person. This visit carries a cost — it is also the part that makes an estimate hold up later.
-
3
Plans and concepts, together
We sit down with you and go through the plan, the blueprints and the concept until the scope is something you recognise as your own.
-
4
Scope, schedule and permits
You get a written scope and a schedule. We handle the permitting so the paperwork never becomes your problem.
-
5
Build and hand over
One point of contact through construction, a walkthrough at the end, and we don’t call it finished until you do.
Built by a Marine
Veteran-founded
Founded and still run by a U.S. veteran. The standards on site come from somewhere.
Licensed & insured
Fully licensed and insured in Hawai‘i, with the paperwork to show you before work starts.
All four islands
O‘ahu, Maui, Big Island and Kaua‘i — we travel for the work.
One point of contact
You deal with the same person from the first visit through to handover.
