Get answers to common questions about insulation services in Shrewsbury, Pennsylvania.
For Shrewsbury's humid continental climate with cold winters and warm, humid summers, a combination of air sealing and high-R-value insulation is key. We typically recommend spray foam in attics and crawl spaces for its superior air-sealing properties, or dense-packed cellulose in walls for older homes, as it performs well against both conductive and convective heat loss common in our area. The goal is to create a continuous thermal barrier that manages moisture from summer humidity and retains heat during our chilly York County winters.
Yes, Pennsylvania offers several programs. The most accessible is the UGI Utilities Home Energy Assessment program, which serves Shrewsbury and can provide rebates for adding insulation to meet recommended R-values. Additionally, the statewide Keystone HELP Energy Efficiency Loan Program offers low-interest financing. We always recommend homeowners check the PA Department of Environmental Protection's website for current listings, as utility-sponsored rebates can change seasonally.
While insulation can be installed year-round, the best times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather in South Central PA, which is crucial for certain materials like spray foam that require specific temperature ranges for proper application. Scheduling during these shoulder seasons also ensures your home is prepared before the peak heating season begins, and you'll find greater contractor availability compared to the last-minute rush in late fall.
First, ensure the contractor is properly licensed and insured to work in Pennsylvania. Look for local companies with strong, verifiable references in the community and membership in organizations like the Building Performance Association (BPA). A reputable provider will always conduct a thorough energy audit or assessment before quoting, as understanding your home's specific air leakage points is critical for our climate. Be wary of door-to-door sales or extreme low-ball quotes that may indicate subpar materials or workmanship.
For many historic or older homes in Shrewsbury's established neighborhoods, adding attic insulation alone is rarely a complete solution. These homes often have significant air leaks in walls, basements, and around windows that undermine insulation performance. A whole-house approach starting with a blower door test to identify leaks, followed by targeted air sealing, and then adding insulation, is the most effective and lasting strategy. This addresses the root cause of drafts and moisture issues common in our region's older housing stock.
