Get answers to common questions about insulation services in Frankford, Delaware.
For Frankford's humid subtropical climate with hot summers and cool winters, blown-in cellulose or fiberglass in attics and walls is often the most cost-effective upgrade. These materials provide excellent thermal resistance (R-value) and help manage the humidity prevalent in Sussex County. For new construction or major renovations, spray foam provides superior air sealing but at a higher initial cost.
Delaware has strong energy efficiency programs. Homeowners should check for rebates through the Energize Delaware Home Performance Program, which offers incentives for insulation upgrades that meet specific performance standards. While Frankford has no unique local codes, all work must comply with the 2018 International Energy Conservation Code (IECC) adopted by Delaware, which sets minimum R-value requirements for our climate zone.
The ideal times are late spring (April-May) and early fall (September-October). These periods typically offer mild, dry weather, which is crucial for proper installation of materials like spray foam and for effective attic work. Scheduling during these shoulder seasons also avoids the peak summer heat, which can make attic work hazardous, and the busy winter rush when contractors are booked for emergency heat loss fixes.
Always choose a contractor licensed and insured in Delaware. Look for local companies with proven experience in Sussex County's older home stock and ask for references from nearby projects. Verify they perform a thorough energy audit or assessment before quoting, and ensure they are certified by manufacturers (like Owens Corning or CertainTeed) and familiar with Energize Delaware's program requirements to help you secure rebates.
Not entirely. While increasing attic insulation is crucial, our coastal Delaware humidity requires a comprehensive approach. A professional should first address air sealing to close gaps in the attic floor, around windows, and in basements/crawlspaces—this stops moist outdoor air from infiltrating. Proper insulation is then installed over this sealed barrier. Combining these steps is key to improving comfort, reducing energy bills, and preventing moisture issues in the building envelope.
