Learn MoreReach out by phone or through our contact form. We will ask a few basic questions about your home and what you are noticing - high bills, hot rooms, moisture smells - so we can send the right person. We respond within 1 business day and can usually schedule your free in-home estimate within a week.
We visit your home, inspect the attic, crawl space, or walls in question, and check for moisture or ventilation issues. Most visits take 30 to 60 minutes. At the end, you receive a written estimate that spells out exactly what is recommended, which materials will be used, and the full cost. No surprises later.
On installation day, the crew handles setup, does any necessary air sealing, then installs the insulation to the agreed specification. When the work is complete, we walk you through what was done so you can see the coverage yourself. We leave your home clean and give you documentation of the work for your records.
We hold a valid Hawaii Contractors License Board license and carry both liability and workers compensation insurance on every project. You can verify our license through the state DCCA website before we arrive.
We visit your home, assess what is actually needed, and give you a written quote - no pressure to book, no charge for the visit. Most estimates are scheduled within one week of your first call.

They scheduled us within a week and finished the attic insulation in one day. The crew showed us photos of the finished work before leaving, and our electric bill came down noticeably the following month.
David K., Kailua - Attic Insulation
We had a musty smell in the crawl space that had been there for years. After they installed the vapor barrier and crawl space insulation, it was gone within a few weeks. Wish we had called sooner.
Marie T., Kaneohe - Crawl Space Vapor Barrier
Our home was built in the 1960s and had almost nothing in the walls. The spray foam retrofit made a real difference in how the back bedroom feels - it used to be the hottest room in the house.

Yes. Insulation that absorbs moisture - like some older fiberglass batts - can compress, grow mold, and lose effectiveness in Kaneohe's wet windward climate. Moisture-resistant options like closed-cell spray foam hold up much longer here.
Hawaii's residential electricity rates are among the highest in the nation - often two to three times the mainland average. That means every degree of heat your insulation blocks translates into more savings per month than the same upgrade would in most other states.
Very likely. Many windward Oahu homes from the 1950s through 1970s were built with minimal or no insulation - Hawaii's building codes at the time didn't require it. Decades of humidity and settling make the situation worse over time.
Trade winds help, but they don't blow every day - and when they stall in summer, indoor temperatures spike quickly. Insulation stabilizes your home's temperature regardless of wind conditions. The two work together, not as substitutes.
Almost always. Air sealing gaps around pipes, wires, and fixtures before insulating prevents conditioned air from escaping where you cannot see it. Skipping this step means your new insulation underperforms from day one.
Spray foam can last the lifetime of the building. Blown-in cellulose or fiberglass typically lasts 20 to 30 years if the attic stays dry. Moisture intrusion and pest activity are the main threats to longevity in Kaneohe specifically. The{' '}U.S. Department of Energy's insulation guidance at energy.gov/energysaver is a useful reference for understanding product lifespan.

We hold a valid contractor license issued by the Hawaii Contractors License Board under the Hawaii Department of Commerce and Consumer Affairs - the state authority that governs residential and commercial contractor licensing in Hawaii.

Learn more about our companyIf your existing insulation is wet, moldy, pest-damaged, or contaminated, adding new material on top traps the problem underneath. Old material should be removed first so the new insulation can perform as intended.
Yes, in most cases. If the existing material is dry and undamaged, contractors can blow new insulation directly on top to bring it to the recommended depth. This avoids removal costs and reduces disruption.
For blown-in and batt insulation, there is no waiting period - your home is ready immediately. Spray foam requires a few hours of ventilation before re-entry, but cures fully within 24 hours of application.
The EPA's guide to mold and moisture is a helpful reference if you suspect existing insulation has been compromised. Ready to schedule a free assessment? Contact us here.
Kaneohe sits on the windward side of Oahu and is one of the rainiest communities in Hawaii, receiving 60 to 70 inches of rainfall per year on average. The NOAA climate data for the windward Oahu region reflects a year-round wet pattern that sets this community apart from the drier leeward side of the island. With a population of roughly 34,000 to 35,000 residents spread across the valley and lower Ko'olau foothills, Kaneohe is a mid-size residential community where most people own their homes and invest in long-term upkeep.
The Kaneohe Bay, the largest sheltered bay in Hawaii, runs along the western edge of the community, and the dramatic Ko'olau Mountain Range forms the green backdrop behind the valley. Homes near the bay deal with salt air and higher humidity, while hillside properties up against the Ko'olau mountains can see even more rainfall than the valley floor. The Ho'omaluhia Botanical Garden, a 400-acre public garden run by the City and County of Honolulu, is a well-known local landmark that anchors the community's identity. Marine Corps Base Hawaii on the Mokapu Peninsula brings a steady population of military families to the area, many of whom live in off-base homes across Kaneohe's neighborhoods.
Most of Kaneohe's housing stock was built between the 1950s and 1980s - a period when insulation standards in Hawaii were minimal compared to what is required today. That means a large share of homes in the area have under-insulated attics, unsealed wall cavities, and crawl spaces that let ground moisture rise into the living areas. Kaneohe Insulation works in these homes every week and knows exactly what the windward climate demands from insulation materials and installation methods.
