How Much does spray foam cost?

The cost of spray foam insulation can vary based on several factors—including the type of foam used (open-cell vs. closed-cell), the size of the space, and whether it's a new build, older home, basement, crawl space, or commercial project. Every job is unique, and pricing depends on the specific needs of your property.

does spray foam make a home too tight?

It’s a common question—but the short answer is no, spray foam does not make a home “too tight.” In fact, building science has proven that creating an airtight home—when paired with a properly designed HVAC system—is the most efficient and comfortable way to live.

Look at examples from industries where performance and efficiency matter most:
Commercial jetliners, refrigerated trailers, and cold storage warehouses are all sealed with spray foam or other high-performance air barriers. These environments are extremely airtight—yet they function perfectly with the right ventilation and climate control systems.

Modern HVAC systems are now designed to account for airtight construction. Most reputable heating and cooling contractors use software that calculates your home’s exact heating and cooling needs based on its insulation levels, size, orientation, and layout. This ensures your system provides the right amount of airflow and humidity control for a healthy, balanced indoor environment.

With proper HVAC design, spray foam improves indoor air quality, reduces drafts, and prevents moisture issues—without making your home “too tight.”

Does spray foam cause problems with shingles?

No—spray foam insulation applied to the roof deck does not cause shingles to curl. The main factors that impact shingle lifespan are color, direction the roof faces, and type or style of shingle used—not insulation.

In fact, sealed attics with spray foam insulation stay within just 2–4°F of your indoor thermostat setting, dramatically reducing heat buildup in the attic. That means the shingles are exposed to less heat from below, and the primary heat source becomes the sunlight itself—not attic air.

Shingle color also plays a major role. According to multiple studies, lighter-colored shingles can reflect more sunlight and stay up to 15–25°F cooler than darker shingles in the same conditions. This reduces thermal stress and can help prolong the life of your roof.

Spray foam insulation helps stabilize attic temperatures, improves energy efficiency, and supports better overall roof performance—without damaging your shingles.

Can you spray foam be pumped into enclosed walls?

Some companies say they can pour foam into closed walls, while there are pour foams, in homes it usually doesn’t work well. Spray foam is made to be sprayed into open walls. It expands rapidly and needs room to grow. If it’s sprayed into a closed space, it can push too hard and might even damage the wall.

Also, many older homes have blocks, braces, pipes, wires, or existing insulation inside the walls that would stop the foam from spreading evenly. That means parts of the wall won’t be properly insulated.

To get the best results, spray foam should be used in open walls where we can see what we’re doing and make sure every part gets filled, in turn saving everyone time, money, and peace of mind.
