Serving Carlisle and Cumberland County Since 2013

Carlisle is one of Pennsylvania’s older boroughs, and its housing stock reflects that history. The borough itself has a significant number of older homes built in the 18th and 19th centuries alongside mid-century construction in the surrounding neighborhoods. Many of these homes were built before modern insulation standards existed and have significant room for improvement.

Beyond the borough, Cumberland County extends into newer suburban areas like South Middleton Township and into older rural properties throughout the rest of the county. Each of these presents different insulation challenges, and we approach every home as its own situation rather than applying a standard formula.

York Home Performance is based in Glen Rock, PA, approximately 40 miles from Carlisle. We serve Cumberland County regularly and are familiar with the utility programs and housing types common to the area.

Insulation and Home Performance Services in Cumberland County

We offer the full range of insulation and home performance services for Carlisle-area homeowners. Every project starts with a proper diagnostic assessment, so we understand your home before recommending anything.

Attic insulation installation by York Home Performance

Attic Insulation


The attic is typically where the most energy is lost in older central Pennsylvania homes. We install blown-in fiberglass, blown-in cellulose, batt, spray foam, and mineral wool insulation to bring your attic to the correct R-value for Pennsylvania's climate zone. We air-seal the attic before adding insulation, which is the step that determines how well the insulation actually performs.

Wall insulation installed by York Home Performance

Wall Insulation


Many of Carlisle's older homes were built without wall insulation or with materials that have since degraded. We inject insulation into existing walls using minimally invasive methods that do not require removing drywall. For homes with significant wall heat loss, this upgrade can make a noticeable difference in comfort and energy bills.

Crawl space insulation installed by York Home Performance

Crawl Space Insulation


Cumberland County properties with vented crawl spaces often experience moisture, cold floors, and energy loss from below-ground spaces. We insulate and encapsulate crawl spaces to seal out moisture, improve floor temperatures, and reduce heating loads in your home. It is a particularly valuable upgrade in older rural properties throughout the county.

Basement insulation installed by York Home Performance

Basement Insulation


Rim joist and basement wall insulation reduces cold drafts at floor level and improves comfort throughout the home. It is a cost-effective upgrade that delivers consistent results and is often overlooked in favor of the attic, even though it can significantly improve overall performance.

Professional air sealing of a home by York Home Performance

Air Sealing


Air sealing closes the gaps and penetrations through which conditioned air escapes your home. It is the foundational step in any home performance project and the one that makes insulation work as intended. We include it in every job rather than treating it as an optional add-on.

Home Energy Audits


A blower door test and thermal imaging scan give us an accurate picture of where your home is losing energy. Audits start at $100-$150, are often rebate-eligible, and allow us to make specific, data-driven recommendations rather than general ones. Many Carlisle homeowners discover that the biggest problem is not where they expected it to be.
