Get answers to common questions about insulation services in Greer, South Carolina.
For our humid subtropical climate with hot summers and mild winters, blown-in fiberglass or cellulose in the attic is often the most cost-effective initial upgrade. These materials provide excellent thermal resistance (R-value) and help block summer heat gain, which is your primary concern. For new construction or major renovations, spray foam provides superior air sealing and moisture control, but at a higher upfront cost.
The ideal times are during the mild spring (March-May) and fall (September-November) seasons. This avoids the extreme attic heat of a Greer summer, which can be dangerous for installers and can affect some materials, and the potential for winter moisture issues. Scheduling during these shoulder seasons also ensures your home is prepared for the more temperature-driven energy demands of summer and winter.
While South Carolina has no statewide insulation code for existing homes, Greer follows the 2018 International Residential Code for new construction, requiring specific R-values (e.g., R-30 to R-60 in attics). Importantly, check for rebates from Duke Energy, the primary utility in Greer, which often offers incentives for adding insulation. Always ensure your contractor pulls any required local building permits for the work.
Look for licensed, insured contractors with specific experience in our region's humidity and pest concerns (like insulating against rodents). Ask for local references in Greer or nearby communities like Taylors or Spartanburg, and verify they perform a thorough energy audit or assessment before quoting. Membership in local associations like the Home Builders Association of Greenville can also be a good indicator of reputation.
Properly installed insulation itself does not cause mold; it's a symptom of inadequate ventilation and air sealing. In Greer's high humidity, a critical step is ensuring your attic has proper soffit and ridge venting to allow hot, moist air to escape. A quality contractor will assess and correct ventilation issues and use materials like spray foam or cellulose that can manage moisture better than standard batts in our climate.
