Serving Honolulu, HI and surrounding areas. (808) 509-0068
Custom Honolulu Insulation was founded in 2016 by a team that grew up working on Honolulu homes and knew firsthand how under-insulated most of them were. Back then - and still today - many of the homes in neighborhoods like Kaimuki, Manoa, and Palolo were built in the 1950s and 60s, long before energy efficiency was on anyone's mind. Owners were paying sky-high electricity bills every summer and wondering why their AC never quite kept up.
The answer, in most cases, was simple: little to no insulation. Hawaii's older housing stock was designed for natural ventilation, not modern air conditioning. We set out to fix that, one home at a time, by bringing proper insulation and air sealing to properties that needed it badly.
Today, we serve homeowners and businesses across Oahu - from Honolulu proper out to Pearl City, Kailua, Kaneohe, and beyond. We are a local business, not a franchise. Every job is handled by our own trained crew, not a subcontractor you have never met. That means you always know who is coming to your home and who is accountable for the work.
We tell you what your home actually needs. If a simple top-up will do the job, that is what we recommend - not a full tear-out.
We treat your home like it is our own. Work areas are prepped before we start and cleaned up completely before we leave.
Honolulu homes have unique needs - older construction, high humidity, salt air. We know what to look for and how to address it.
We keep our appointments, communicate clearly, and do not leave you waiting around. Your time matters.
Every project starts with a free on-site assessment and a written estimate that breaks down materials, labor, and any air sealing work, so you know the full scope before anyone starts.
We document every job from the written estimate to the final walkthrough and coordinate permits when a project calls for it. Your work is on record and easy to reference later.
We have been working on Oahu homes and businesses since 2016. That track record across 12 communities means we understand local construction, local permitting, and the specific challenges of Hawaii's climate.
