Get answers to common questions about insulation services in Glendale, 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 in the Upstate. For new construction or major renovations, spray foam provides superior air sealing but comes at a higher upfront cost.
The ideal times are during the mild spring (March-May) and fall (September-November) seasons. This avoids the extreme heat of a Glendale summer, which can make attic work dangerous for crews and less effective for certain materials like spray foam that require specific temperature ranges. Scheduling in these off-peak seasons can also lead to better availability and sometimes promotional pricing from local contractors.
Yes, Glendale homeowners should check for incentives from Duke Energy, the primary utility provider in the area. They often offer rebates for adding attic insulation to meet specific R-value recommendations (typically R-38 to R-60 for our zone). Additionally, federal tax credits for certain insulation materials may be available; a reputable local installer will be up-to-date on these programs to help you maximize savings.
Always verify the contractor is licensed and insured in South Carolina. Look for established local companies with strong references in the Upstate community, as they understand our specific humidity and pest challenges (like rodents and insects). Ask if they perform a pre-installation energy assessment and provide a detailed, written quote that includes the specific R-value to be achieved, not just the depth of material.
In almost all cases, prioritize the attic. Heat rises, making the attic the single largest source of energy loss in our climate. Adding or upgrading attic insulation typically offers the fastest return on investment for improving comfort and reducing air conditioning costs. After addressing the attic, consider wall insulation, especially if your home has hollow walls, but a professional energy audit can pinpoint the most critical areas for your specific house.
