WHAT WE DO
Our Services
From attic to crawl space, we handle every part of the building envelope with certified energy auditors on every job.
Attic Insulation
Attic insulation is the single highest-impact upgrade in most homes. We install blown-in, batt, and spray foam insulation to bring your attic to the recommended R-value for Pennsylvania or Maryland. That means less heat escaping in winter and less heat entering in summer.
Wall Insulation
Cold walls and high heating bills often signal missing or degraded wall insulation. We inject insulation into existing walls using minimally invasive methods. No drywall removal required in most cases.
Crawl Space Insulation
A damp, uninsulated crawl space affects your entire home. We insulate and encapsulate crawl spaces to control moisture, improve floor comfort, and reduce the load on your heating and cooling system.
Basement Insulation
Insulating rim joists and basement walls eliminates drafts at floor level and improves comfort in the rooms above. It is one of the most cost-effective insulation upgrades available, and it reduces heating costs year-round.
Air Sealing
Before insulation goes in, we seal the gaps, cracks, and penetrations where conditioned air escapes your home. Air sealing is what makes insulation perform as designed. It is also the step most contractors skip. We do not.

Frequently Asked Questions
Common questions from homeowners across Pennsylvania and Maryland about insulation, energy audits, and utility rebate programs.
How much does attic insulation cost in Pennsylvania or Maryland?
Attic insulation typically ranges from $1,500 to $4,500, depending on attic size, current insulation levels, and the material used. PPL Electric, FirstEnergy, and BGE rebate programs can significantly reduce your out-of-pocket cost. We check your rebate eligibility for every estimate.
Do you work with PPL Electric, FirstEnergy, and BGE rebate programs?
Yes. York Home Performance is an approved contractor for PPL Electric and FirstEnergy in Pennsylvania, and for the BGE Home Performance with ENERGY STAR program in Maryland. We submit rebate paperwork directly on your behalf and guide you through the full program process from audit through rebate approval.
How long does an insulation job take?
Most attic insulation jobs are completed in a single day. Crawl space encapsulation and full air-sealing projects typically take 1 to 2 days, depending on the size and condition of the space. We give you a clear timeline before any work begins.
What is a home energy audit, and do I need one?
A home energy audit is a diagnostic assessment of where your home is losing energy. We use a blower door test to measure air leakage and thermal imaging to identify heat loss through walls, ceilings, and floors. Audits start at $100-$150 and are often the required first step before utility rebate programs will approve improvements in both PA and MD.
What is the difference between insulation and air sealing?
Insulation slows the transfer of heat through surfaces like walls, ceilings, and floors. Air sealing closes the physical gaps and cracks where conditioned air actually escapes your home. Both are necessary. We always air-seal before installing insulation because adding insulation over air leaks significantly reduces its effectiveness.
What insulation materials do you install?
We install blown-in fiberglass, blown-in cellulose, batt insulation, spray foam, and mineral wool (Rockwool). For existing walls, we use injection foam, a minimally invasive method that does not require removing drywall. We recommend the right material after assessing your specific home and goals.
