Serving Lancaster County Homeowners Since 2013

Lancaster County has a mix of older farmhouses, row homes, and newer construction spread across a large rural and suburban area. That variety means insulation needs vary a lot from property to property. A 100-year-old farmhouse in Ephrata has very different needs than a 1980s split-level in Lititz.

York Home Performance works throughout Lancaster County. We start every project with a thorough assessment to understand your specific home before recommending anything. Whether you are dealing with high heating bills, cold rooms, moisture issues in a crawl space, or drafty walls, we diagnose the problem first and then solve it.

Our team is based in Glen Rock, PA, about 30 miles from Lancaster. We regularly serve Lancaster and the surrounding communities and are familiar with the area’s housing stock and utility programs.

Insulation and Home Performance Services in Lancaster County

We offer the full range of insulation and home performance services for Lancaster County homeowners. Every job starts with a proper assessment, and every recommendation is backed by diagnostic data.

Attic insulation installation by York Home Performance

Attic Insulation


The attic is where most Lancaster-area homes lose the most energy. 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 that makes the biggest difference in real-world performance.

Wall insulation installed by York Home Performance

Wall Insulation


Older Lancaster County homes, particularly row homes and farmhouses, often have little to no wall insulation. We inject insulation into existing walls without removing drywall, using methods that are minimally invasive and effective for the construction types common in this area.

Crawl space insulation installed by York Home Performance

Crawl Space Insulation


Many Lancaster County homes, especially older rural properties, have vented crawl spaces that allow moisture, cold air, and pests to affect the living space above. We insulate and encapsulate crawl spaces to control moisture, improve floor comfort, and reduce energy loss from below.

Basement insulation installed by York Home Performance

Basement Insulation


Insulating rim joists and basement walls reduces drafts, improves comfort on the floors above, and lowers heating costs year-round. It is a cost-effective upgrade that is often overlooked in favor of the attic but delivers strong results, particularly in older homes.

Professional air sealing of a home by York Home Performance

Air Sealing


Before any insulation is installed, we seal the gaps, cracks, and penetrations where conditioned air is escaping from your home. Air sealing is often the highest-impact step in a home performance project, and the one most contractors skip. We include it in every job.

Home Energy Audits


A blower door test and thermal imaging scan identify exactly where your home is losing energy. Energy audits start at $100 - $150, are often rebate-eligible, and provide diagnostic data to make accurate recommendations. Many Lancaster County homeowners are surprised by what the testing reveals.
