Get answers to common questions about insulation services in Sewell, New Jersey.
For our humid summers and cold winters, a combination of air sealing and attic insulation is critical. We recommend spray foam or blown-in cellulose for attics to achieve a high R-Value (ideally R-49 to R-60) and prevent ice dams. Proper basement and crawl space insulation is also key to combat ground moisture and drafts common in Gloucester County.
Costs vary by home size and material, but Sewell homeowners can expect to invest between $1,500 to $4,500 for a standard attic insulation project. Blown-in fiberglass is often the most cost-effective, while spray foam commands a premium but offers superior air sealing. Always get itemized quotes from local contractors that include removal of old insulation if needed, as this is a common requirement in older South Jersey homes.
Yes. New Jersey's Clean Energy Program (NJCEP) offers significant rebates for insulation upgrades that improve home performance. Additionally, Sewell residents served by South Jersey Gas or Atlantic City Electric can access Home Performance with ENERGY STAR® assessments and incentives. These programs often cover a portion of the audit and installation costs, making upgrades more affordable.
Prioritize contractors licensed and insured in New Jersey with specific experience in our climate. Look for companies that perform a pre-installation energy audit and are certified by the Building Performance Institute (BPI). Check for strong local references in Sewell or Washington Township, as they will understand regional building codes and common issues like managing humidity in our older colonials and ranches.
While insulation can be installed year-round, the ideal times are late spring (April-May) and early fall (September-October). These periods offer moderate temperatures in South Jersey, making it easier for contractors to properly install materials and for your HVAC system to be tested effectively. Avoid the peak summer heat and deep winter cold to ensure crew safety and optimal material performance.
