Get answers to common questions about insulation services in Greenwood, South Carolina.
For Greenwood's hot, humid summers and mild but occasionally chilly winters, spray foam and blown-in fiberglass are top choices. Spray foam provides an excellent air seal against humidity, while blown-in fiberglass is a cost-effective option for achieving high R-values. The South Carolina Energy Office recommends attic insulation levels of R-38 to R-60, which is crucial for managing both summer cooling costs and winter heating from our heat pumps.
Costs vary based on home size, insulation type, and existing conditions, but Greenwood homeowners can expect to pay between $1,500 and $4,500 for a professional attic insulation project. Blown-in cellulose or fiberglass is generally more affordable upfront, while spray foam commands a higher price but offers long-term energy savings. Always get itemized estimates from local contractors that include material R-value, labor, and any necessary air sealing.
The ideal times are during the mild periods of spring (March-May) and fall (September-November). Attic work in our scorching summer heat is strenuous and less efficient, while winter projects might be delayed by occasional freezing rain. Scheduling during these shoulder seasons ensures contractor availability and allows you to optimize your home's efficiency before peak heating and cooling seasons.
Yes, homeowners should first check for rebates from their local utility, such as Duke Energy, which often offers incentives for adding insulation to meet specific R-values. Additionally, the federal tax credit for energy efficiency (26C) can cover 30% of qualified insulation material costs, up to a $1,200 annual limit. It's wise to ask your Greenwood insulation contractor about current programs during your estimate.
Prioritize licensed, insured contractors with proven local experience in our specific climate challenges. Ask for references from Greenwood-area projects and verify they perform a thorough assessment, including a moisture check, given our high humidity. A reputable provider will clearly explain how their solution addresses air infiltration and meets the recommended R-values for our South Carolina climate zone (Zone 3).
