What to know about Spray foam insulation
Spray polyurethane foam insulates and air seals in one pass, which is why it wins on complicated geometry where batts cannot be made to fit. It is also a chemical reaction carried out inside your house, and that is the part homeowners are rarely told enough about. CPSC's consumer fact sheet, which compiles guidance from EPA, OSHA, NIOSH, NIST and ASTM, describes the chemistry plainly: high-pressure systems and low-pressure kits are two parts mixed during application, with isocyanates in Side A and a mixture of polyols, amine catalysts, flame retardants, blowing agents and surfactants in Side B.

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Area to insulate: attic, walls, basement or crawl space
- Type of insulation
- Removal of old insulation
- Air sealing work
- Access to the space
- Ventilation changes
How to choose spray foam contractors in Hilo
- Choose a contractor who talks about air sealing and ventilation, not only adding more insulation.
- Ask them to check the attic or walls for moisture, mould, old wiring or insulation that may contain asbestos before starting.
- Get a written quote that states the type of insulation, the areas covered and the target insulation level.
- For spray foam, ask about their training, curing time and when it's safe to be back in the home.
- Consider an energy audit before and after the work to see where heat is being lost.
Questions to ask spray foam contractors before you hire
- What type of insulation do you recommend for this area, and why?
- Will you seal air leaks before insulating?
- How will you keep the attic properly ventilated?
- What will you do if you find old insulation that may contain asbestos, mould or old wiring?
- For spray foam, how long do we need to stay out of the house?
- Does this work need a permit or an inspection?
Spray foam insulation permits in Hawaii
Some spray foam insulation work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
Licensing in Hawaii
Consumer protection
Verify the licence yourself rather than accepting a card. The Department publishes a free online licence search where you can see the original licence date, expiration date, licence status and any disciplinary action, and it also takes licence checks by phone.
