How Much Does Attic Insulation Cost in Shreveport? (Honest 2026 Pricing Guide)
Attic insulation costs vary by home.
In Shreveport, many homeowners can expect to spend about $1,500 to $4,500 for attic insulation alone. A larger project that includes insulation removal and air sealing may cost $2,750 to $6,500 or more.
Your final price depends on attic size, insulation depth, access, existing damage, and the amount of preparation required.
If you are asking, “How much is attic insulation?”, this guide explains the main costs for homeowners in Shreveport, Bossier City, Haughton, Benton, and nearby communities.
Average Attic Insulation Cost in Shreveport
Published 2026 cost data places a typical Shreveport insulation project around $2,025 to $2,527. A current national attic insulation guide lists an average project cost near $2,100, with typical prices between $1,700 and $2,500.
Those figures are useful starting points.
They may not include:
- Removing old or damaged insulation
- Detailed attic air sealing
- Repairs after roof leaks
- Difficult attic access
- Upgrading to a higher R-value
- Extensive cleanup or disposal
For a typical Shreveport home, use these planning ranges:
| Project scope | Typical planning range |
|---|---|
| Add blown-in insulation to a usable attic | $1.25–$2.50 per sq. ft. |
| R-38 blown-in insulation upgrade | Often $1.25–$2.50 per sq. ft. |
| Remove old attic insulation | $1.00–$2.00 per sq. ft. |
| Attic air sealing | About $250–$1,000 |
| Full removal, air sealing, and new insulation | Often $2,750–$6,500+ |
These are planning ranges, not fixed quotes. A free attic inspection gives you a more accurate number for your home.
What Does Blown-In Attic Insulation Cost?
Blown-in insulation is one of the most practical choices for existing homes.
A professional uses a blowing machine to distribute loose-fill fiberglass or cellulose across the attic floor. The material fills spaces around joists, pipes, wiring, and other areas that can be difficult to cover with rolls or batts.
The cost usually depends on:
- Attic square footage
- Current insulation depth
- Desired R-value
- Insulation material
- Attic access
- Amount of prep work
- Labor and cleanup
A reasonable Shreveport budget for blown-in insulation is about $1.25 to $2.50 per square foot.
For example:
- 1,000-square-foot attic: approximately $1,250–$2,500
- 1,500-square-foot attic: approximately $1,875–$3,750
- 2,000-square-foot attic: approximately $2,500–$5,000
The price may be lower when your existing insulation is clean, dry, and suitable for a top-up. It may be higher when the attic needs removal, sealing, repairs, or extensive cleanup.

How Much Does an R-38 Attic Insulation Upgrade Cost?
R-value measures how well insulation resists heat flow.
A higher R-value generally provides stronger protection against outdoor heat and indoor temperature loss. D&M Insulation offers R-38 attic insulation upgrades for homeowners who need more coverage.
The cost of an R-38 upgrade depends on how much insulation is already in the attic.
If your attic has some good insulation
A contractor may be able to add more blown-in insulation over the existing material.
This can lower the total price because removal and disposal may not be needed.
If your attic has very little insulation
More material and additional labor may be required to reach the target depth.
The installer also needs to check for air leaks and areas around fixtures, ductwork, and attic penetrations.
If your insulation is wet, dirty, or damaged
The old material may need to be removed before new insulation is installed. This creates an additional removal and disposal cost.
An R-38 upgrade is not just about adding a certain number of bags of insulation. The attic must receive even coverage at the correct depth. Professional installation helps prevent thin areas and missed sections.
How Much Does Attic Insulation Removal Cost?
Old insulation should not always be covered with new material.
Removal may be recommended after:
- A roof leak
- Storm damage
- Water intrusion
- Pest activity
- Mold or contamination concerns
- Fire or smoke damage
- Major attic debris
- Severe settling or deterioration
Attic insulation removal commonly costs about $1.00 to $2.00 per square foot in the Shreveport area.
For a 1,500-square-foot attic, that can add approximately $1,500 to $3,000.
The cost depends on the type and condition of the material. Loose-fill insulation is often removed with specialized vacuum equipment. Difficult access, heavy debris, and disposal requirements can increase the price.
Removing damaged material creates a cleaner starting point for new insulation. It also makes it easier to inspect the attic deck, find air leaks, and identify moisture problems before the new insulation is installed.
D&M Insulation provides insulation removal and attic cleanout services after roof leaks, storm damage, and other attic problems.
How Much Does Attic Air Sealing Cost?
Air sealing closes the gaps that allow conditioned air to escape.
Common leak locations include:
- Plumbing and electrical penetrations
- Attic access openings
- Ductwork gaps
- Top plates
- Recessed light areas
- Chimney and flue openings
- Gaps around vents and wiring
Basic attic air sealing often costs about $250 to $750. More extensive work may cost $750 to $1,000 or more, depending on the number and size of the leaks.
Air sealing is important because insulation does not stop every air leak. Without sealing, cooled air can escape into the attic during the hot Louisiana summer. Your HVAC system may then run longer to maintain the temperature inside your home.
Combining air sealing with insulation can help provide:
- More consistent room temperatures
- Less energy waste
- Better HVAC performance
- Fewer drafts
- Improved attic efficiency
- Greater comfort throughout the home
Air sealing is usually completed before new blown-in insulation is installed.
Example Project Costs for Shreveport Homes
Every attic is different, but these examples show how the costs can fit together.
1,000-Square-Foot Attic
A project with new blown-in R-38 insulation, limited air sealing, and no removal may cost approximately:
- New insulation: $1,250–$2,500
- Air sealing: $250–$750
- Estimated total: $1,500–$3,250
If old insulation must be removed, the total may increase to approximately $2,500–$4,500.
1,500-Square-Foot Attic
A larger attic with new insulation and air sealing may cost approximately:
- New insulation: $1,875–$3,750
- Air sealing: $250–$1,000
- Estimated total: $2,125–$4,750
If removal is required, a full project may reach $4,000–$6,500 or more.
Large attics, tight access, storm damage, wet insulation, and extensive air leaks can all increase the total.
