Serving Harrisburg and Dauphin County Since 2013

Harrisburg and the surrounding Dauphin County area includes a wide range of home types. Older row homes and twin houses in the city proper, mid-century ranches and colonials in the suburbs, and larger properties in communities like Hershey and Hummelstown all have different insulation profiles and different challenges.

York Home Performance works across all of Dauphin County. We base every recommendation on a proper assessment of your specific home rather than a one-size-fits-all approach. Whether the issue is a poorly insulated attic, cold walls, a damp crawl space, or high energy bills with no obvious cause, we diagnose the problem first and then address it correctly.

Our office is in Glen Rock, PA, about 35 miles south of Harrisburg. We serve the Harrisburg area on a regular basis and are familiar with the housing stock and utility programs serving Dauphin County.

Insulation and Home Performance Services in Dauphin County

We offer the full range of insulation and home performance services for Harrisburg-area homeowners. Every project starts with a proper diagnostic assessment and every recommendation is grounded in what the testing shows.

Attic insulation installation by York Home Performance

Attic Insulation


The attic is the most common source of energy loss in Harrisburg-area homes. We install blown-in fiberglass, blown-in cellulose, batt, spray foam, and mineral wool insulation to bring your attic to the R-value recommended for Pennsylvania’s climate. We always air seal the attic before adding insulation, which is the step most contractors skip and the one that makes the biggest difference.

Wall insulation installed by York Home Performance

Wall Insulation


Many older Harrisburg homes, particularly the city’s row houses and twins, were built with little or no wall insulation. We inject insulation into existing walls using minimally invasive methods that do not require removing drywall. It is an effective upgrade for homes where wall heat loss is a significant contributor to high energy bills.

Crawl space insulation installed by York Home Performance

Crawl Space Insulation


Homes in Dauphin County with vented crawl spaces often deal with moisture infiltration, cold floors, and energy loss from below. We insulate and encapsulate crawl spaces to seal out moisture, improve floor comfort, and reduce the heating and cooling load on your home.

Basement insulation installed by York Home Performance

Basement Insulation


Insulating rim joists and basement walls reduces drafts at floor level and improves comfort in the rooms above. It is a cost-effective upgrade that delivers consistent results in both older city homes and suburban construction throughout the Harrisburg area.

Professional air sealing of a home by York Home Performance

Air Sealing


Air sealing closes the gaps, cracks, and penetrations where conditioned air is escaping your home. It is the foundational step that makes insulation perform correctly and often the single highest-impact improvement we make. We include air sealing in every project.

Home Energy Audits


A blower door test and thermal imaging scan show exactly where your home is losing energy. Audits start at $100-$150, are often rebate-eligible, and give us the diagnostic data to make accurate, specific recommendations. Many Harrisburg homeowners are surprised by what the testing uncovers.

UTILITY REBATE PROGRAMS

Rebate Programs Available to Harrisburg Homeowners

PPL Electric

Most Harrisburg-area homeowners are PPL Electric customers. PPL offers rebates on qualifying insulation and air-sealing improvements, and income-qualified households may be eligible for the WRAP program, which provides free home upgrades.
