Get answers to common questions about insulation services in Garnet Valley, Pennsylvania.
For our humid continental climate with cold winters and hot, humid summers, a combination of air sealing and high-performance insulation is key. We typically recommend spray foam for its superior air barrier in attics and rim joists, and dense-packed cellulose or fiberglass batts in walls. This approach effectively manages both winter heat loss and summer heat gain, which is crucial for year-round comfort and energy savings in Pennsylvania.
For a standard 1,200 sq ft attic, adding blown-in cellulose or fiberglass insulation to achieve the recommended R-49 for our zone typically costs between $1,500 and $2,500. Spray foam will be higher. Homeowners in Delaware County should check for rebates from PECO, as they often offer incentives for adding insulation. Additionally, the federal tax credits for energy efficiency improvements can provide significant savings on qualifying materials.
While insulation can be installed year-round, the ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is important for certain materials like spray foam that have specific temperature application ranges. Scheduling during these shoulder seasons also avoids the peak summer heat in the attic and the contractor backlog that often occurs right before winter.
Always verify the contractor is properly licensed and insured in Pennsylvania. Look for local companies with strong references in Garnet Valley and surrounding towns, as they will understand specific building codes and common home styles (like older colonials or new developments). Crucially, choose a provider that conducts a thorough energy audit or assessment first, as air sealing is just as important as adding insulation itself for our climate.
Not entirely. Drafts are caused by air leaks, which insulation alone does not stop. The most effective strategy for older Pennsylvania homes is a two-step process: first, professional air sealing of gaps in attics, basements, and around windows and doors; then, adding the proper amount of insulation. This comprehensive approach addresses both conduction and air infiltration, which is the best way to improve comfort and reduce those high PECO winter heating bills.
