Professional Insulation Services in Ho-Ho-Kus, NJ

Blown-in attic insulation in the Ho-Ho-Kus area typically starts at $1.60 per square foot, so a standard 1,500 sq ft attic usually lands in the $2,400 to $4,000 range. Spray foam costs more per square foot but seals air leaks at the same time. Final price depends on attic size, the R-value you’re starting from, and the insulation type. Every quote is written, itemised, and free.

For most Ho-Ho-Kus homes, blown-in cellulose over the attic floor combined with air sealing gives the best result for the money — it fills gaps around joists and wiring that batts leave open. Spray foam is the better choice when you need to air seal the roof deck itself or convert the attic into conditioned space. We recommend a type after inspecting your attic, not before.

Ho-Ho-Kus sits in climate zone 4A, where the Department of Energy recommends R-49 to R-60 for attics. Most Ho-Ho-Kus homes built before 2000 come in around R-19 to R-30, which is well short. R-49 is also the level required for the NJ Clean Energy Program rebate. We measure your current R-value during the free evaluation and tell you exactly where you stand.
