Attic Insulation Services
Your attic is the single most impactful place to improve your home's energy efficiency. Heat rises, and in a home with inadequate attic insulation, it rises straight out of the house. In summer, an uninsulated attic absorbs heat and radiates it down into your living space.York Home Performance installs attic insulation for homeowners across Pennsylvania and Maryland. We are a BPI-certified contractor with over 13 years of experience. We install blown-in, batt, and spray foam insulation and help homeowners qualify for utility rebates that reduce the cost of the project.
Why Attic Insulation Delivers the Highest Return
The U.S. Department of Energy estimates that properly insulating and air sealing the attic can reduce heating and cooling costs by up to 20 percent. For most homes, the attic is where the most energy is lost and where the greatest improvement is available.
Signs your attic may need attention:
- Energy bills that feel high for the size of your home
- Rooms that are hard to keep comfortable regardless of thermostat settings
- Ice dams forming on your roof in winter
- Noticeable temperature differences between floors
- An attic with less than R-38 of existing insulation
Attic Insulation Materials We Install
We install several types of attic insulation based on your home’s construction, goals, and budget. Every project starts with an assessment, so we recommend the right material for your specific situation.
Blown-In Fiberglass
The most common solution for existing attics. Blown-in fiberglass fills gaps and irregularities that batt insulation can miss, provides good thermal performance, and installs quickly with minimal disruption to your home.
Blown-In Cellulose
Made from recycled paper fiber, blown-in cellulose is a dense, effective insulation material with strong air resistance properties. It is a good choice for attics with complex framing and is often preferred by homeowners seeking a recycled-content option.
Batt Insulation
Fiberglass or mineral wool batts are well-suited for attics with open, accessible framing and minimal obstructions. Batts can be installed quickly and are a cost-effective option when the attic structure allows for a clean application.
Spray Foam
Open or closed-cell spray foam is used in specific attic applications, particularly in unvented attic assemblies or when air sealing and insulating in a single step is the right approach. We assess whether spray foam is the right fit for your attic before recommending it.
Mineral Wool
Mineral wool is fire- and moisture-resistant and provides excellent thermal and acoustic performance. It is increasingly popular for attic applications, particularly in homes where fire safety or moisture management is a concern.

Frequently Asked Questions About Attic Insulation
How much does attic insulation cost?
Attic insulation typically ranges from $1,500 to $4,500 depending on attic size, existing insulation levels, and the material used. Utility rebate programs in PA and MD can reduce your out-of-pocket cost. We provide a written estimate and check your rebate eligibility before any work begins.
What R-value do I need for my attic?
The U.S. Department of Energy recommends R-49 to R-60 for most of the Mid-Atlantic region including Pennsylvania and Maryland. The right target depends on your current insulation levels, your heating system, and your climate zone. We measure your existing levels during the estimate and tell you exactly what your attic needs.
Do you air seal before insulating?
Yes, always. Air sealing attic bypasses and penetrations before adding insulation is the step that makes the greatest difference in real-world performance. Insulation installed over unaddressed air leaks performs significantly below its rated value. We include air sealing in every attic insulation project.
How long does attic insulation take?
Most attic insulation jobs are completed in a single day. We provide a clear timeline before any work begins.
Can you add insulation on top of existing insulation?
In most cases yes. We inspect the existing material first to confirm it is in acceptable condition before adding on top of it. If the existing insulation is compromised, we explain the options.
Where do you provide attic insulation services?
We serve homeowners across Pennsylvania and Maryland including York County, Dauphin County, Lancaster County, Cumberland County, Lebanon County, Adams County, and the greater Baltimore and central Maryland area.
