Philadelphia’s cost of living sits just 5% above the national average, so both insulation materials and installation labor are relatively in line with other parts of the country.
With the city’s cold winters and high heating needs, proper insulation is essential. The main factors affecting the cost of installing new insulation in Philadelphia are the area size, the type of insulation you choose, the installation location, and local labor.
Insulation Installation Cost Factors
How much you’ll spend on installing insulation in Philadelphia, Pennsylvania, depends on a variety of factors, including area size, insulation type, materials, location in the home, and labor. Here’s a closer look at how your costs break down.
Square Footage
You can expect to pay $1 to $4.50 per square foot for insulation installation in Philadelphia, making the size of the area you need to be insulated a significant factor in your total cost. Your total price will be directly correlated to the cost of the material you choose and the size of the area you need to be insulated.
The table below includes some average pricing based on the room size you’re looking to insulate.
| Square Footage | Average Cost |
|---|---|
| 100 | $100–$450 |
| 500 | $500–$2,250 |
| 1,000 | $1,000–$4,500 |
| 2,000 | $2,000–$9,000 |
Materials
Your material choice plays a major role in the price of your installation. In Philadelphia, you can pay anywhere from $0.25 to $6.75 per square foot for insulation, with fiberglass tending toward the lower end and wood fiber insulation toward the upper end. The table below includes some average pricing for different insulation materials.
| Material | Cost per Sq. Ft. |
|---|---|
| Cellulose | $0.60–$2.50 |
| Fiberglass | $0.30–$1.80 |
| Polystyrene | $0.25–$2 |
| Mineral wool | $1.40–$4 |
| Wood fiber | $4.25–$6.75 |
Type of Insulation
The type of insulation you choose for your home depends on your budget and project scope, particularly where you plan to install it, as some types perform better in certain locations than others. When evaluating types, such as blown-in versus spray foam, or if you’re looking for fiberglass insulation alternatives, consider the costs and pros and cons below, keeping Philadelphia’s cold winter temperatures in mind.
| Type of Insulation | Average Cost Per Sq. Ft. | Pros | Cons |
|---|---|---|---|
| Spray foam | $1.50–$3 | Excellent air sealing and high R-value (efficiency); moisture control | Most expensive; requires pro installation; can be messy & harder to modify later |
| Blown-in and loose-fill | $1.20–$1.50 | Fills gaps and irregular spaces well; good for attics or existing walls | Settling can occur over time; less air sealing than spray foam |
| Batt and roll | $0.80–$2 | Generally lower cost; easy to install in open areas | Can leave gaps if not cut/installed carefully; lower air-seal performance |
| Foam board | $1.20–$3.70 | Good thermal resistance per thickness; useful for rim joists and exterior walls | Can be awkward to fit around irregular framing; more labor-intensive |
| Radiant barrier | $0.30–$2 | Reflects heat (good in hot climates/attics); can reduce peak cooling load | Must be used with other insulation types; no R-value |
Location in Home
Where you install the insulation can affect the price, with garages having the lowest cost per square foot and attics having the highest. Here’s a breakdown of how much it costs to insulate each location in your home, including wall insulation costs and prices for other common areas.
| Location | Average Cost per Sq. Ft. |
|---|---|
| Attic | $1.50–$4 |
| Basement | $1.50–$2.50 |
| Garage | $1–$2 |
| Roof | $1.20–$3.50 |
| Wall | $1.50–$4 |
| Ceiling | $1–$3 |
Demolition and Prep
Site prep can add to the cost of your project, but just how much you’ll spend depends greatly on the lengths you need to take to prepare the site. Philadelphia homeowners can spend as little as nothing or as much as $750 for the cost to repair drywall after installing insulation.
Spray foam, in particular, requires extra prep work for proper installation, whereas batt insulation generally goes in with little preparation. Site prep consists of the following:
Cover all valuables, windows, doors, and important surfaces for spray foam installations.
Make sure the electrical wiring is properly installed, and your walls are framed and fully enclosed before installing spray foam to avoid overspray.
Repair any structures in your home, including walls, attics, basements, and crawl spaces.
Remove moldy insulation, conduct a mold test, and hire a mold removal company.
Plan for cleanup costs for removing old insulation and debris.
New vs. Existing Construction
Installing insulation in new construction homes is less expensive than adding it to existing homes, costing about $1 less per square foot. This is because the walls and ceilings are easier to access and install insulation, and you don’t have existing insulation to worry about.
However, many new construction homes use more insulative materials for long-term performance, which tends to be more costly.
A home insulation upgrade costs between $1 and $2 per square foot on average. This doesn’t include disposal fees. Junk removal services add approximately $125 to $400 to your project, depending on the size of the job.
Insulation Pro Costs
In addition to your insulation materials and prep costs, Philly homeowners must consider professional-related expenses when planning an insulation installation project. Here are some costs to budget for when hiring a Philadelphia insulation pro.
Labor
It’s important to work with an expert who knows how to install insulation. Most insulation installers in Philadelphia charge between $45 and $75 per hour, so the more complex the project, the higher the cost. A few complexities that may increase the cost of labor include:
Your installer needs to install insulation in hard-to-reach areas.
You have multiple installation sites in need of insulation.
The installer needs to remove old insulation.
Angi Tip
Correctly installing insulation can be difficult. Health and safety risks are involved; therefore, we highly recommend contacting a pro to ensure the job is completed safely and correctly.
Post-Construction Cleaning
Most insulation installation companies include basic cleanup in their services, but you may wish to hire a professional cleaning company that specializes in construction cleanup. Post-construction cleanup in Philadelphia costs $0.20 to $0.90 per square foot and ensures your space is free of dust and debris after your insulation is installed.
Taxes
The combined state and local sales tax rate in Philadelphia is 8%, and homeowners here indirectly cover this amount on the materials portion of their project. For typical insulation installation as a permanent home improvement, you usually don’t pay tax directly on the contract price. Instead, the contractor pays tax on the materials and includes those costs in their pricing. Installation labor is not taxable.
Additional Pros to Consider Hiring
Along with your insulation installer, you may need to bring additional pros in to finish your project.
Electrician: Bringing in an electrician ensures all wiring is properly installed and is in good condition before you install your insulation, providing peace of mind and reducing the risk of fire. Hiring an electrician costs $50 to $130 per hour.
HVAC technician: An HVAC pro can check and seal all duct connections in the insulated area and make any necessary adjustments to your heating system to ensure optimal performance and energy efficiency. HVAC maintenance costs an average of $250 for a service call.
Does Insulation Installation Increase Home Value?
Proper insulation not only improves your home’s energy efficiency and significantly lowers your heating bills, but it can also boost your resale value. In Philadelphia, you can expect a 100% return on investment (ROI) on installing insulation in your home. Federal rebate and incentive programs can cover a significant portion of your insulation costs, helping boost your ROI and recouping your costs faster.
Because Philadelphia has cold winters and higher heating costs, you’ll likely see stronger savings from attic and wall insulation than in milder climates. Attic and ceiling insulation usually delivers the highest ROI because most heat loss occurs through roofs.
When selling your home, today’s home buyers place an increasing importance on energy efficiency, and new insulation is an upgrade with wide appeal. Homeowners should also prioritize their own comfort and the financial savings from installing new insulation, even before their home hits the real estate market.

They were very good because I thought they would be able to do the outlet installation one way, however we’re not able to. But, they then figured out a way to do the insulation via a different method. I was pleasantly surprised.
