Get answers to common questions about insulation services in Franklin Square, New York.
For our humid summers and cold, wet winters, the top priorities are air sealing and attic insulation. Properly air sealing your attic floor and adding blown-in cellulose or fiberglass to achieve an R-value of R-49 to R-60 is critical to prevent ice dams in winter and reduce summer cooling costs. Basement and crawl space insulation are also highly recommended to combat ground moisture and drafts common in our area.
Costs vary significantly by project scope, but for a standard attic insulation upgrade in a 1,500 sq ft Franklin Square home, homeowners can expect to pay between $1,500 and $3,500. Factors like the insulation material (e.g., spray foam vs. cellulose), accessibility, and the need for air sealing will affect the final price. It's important to get multiple itemized quotes, as Long Island labor and material costs are typically higher than national averages.
Yes, Franklin Square residents should first explore rebates from PSEG Long Island, which often offers incentives for adding insulation and air sealing through their Home Energy Assessment program. Additionally, New York State offers tax credits for certain insulation improvements, and the federal Inflation Reduction Act provides tax credits for qualified energy efficiency upgrades. A reputable local installer will be familiar with these programs.
Always verify the contractor is licensed and insured to work in New York State. Look for companies with specific experience in Nassau County's older home stock, as they'll understand common issues like knob-and-tube wiring or plaster walls. Check for certifications from building performance organizations like BPI (Building Performance Institute) and read local reviews on platforms like Google and Nextdoor to gauge community reputation.
Insulation can be installed year-round, but the ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is important for projects like attic work where extreme summer heat or winter cold can make installation difficult and uncomfortable. Scheduling during these shoulder seasons also ensures your home is prepared before the peak heating and cooling demands hit.
