We’re glad you asked. It’s always a good idea to have a general idea of pricing before you plunge into a home improvement project—especially one with zero cosmetic appeal. Although a fresh coat of paint or a new roof can make a big cosmetic difference, insulation is also very important to achieving year-round comfort and energy efficiency.
Read on to see how this guide can help you understand the benefits, costs, and comparisons of different insulation types.
Why Blown-In Insulation Makes Sense for Stockton:
- Optimal R-Value: We use blown-in insulation (R-38) because it is recommended for attics in many climate zones, including Stockton’s, due to its resistance to heat flow.
- Effective Air Sealing: When done correctly, blown-in insulation fills gaps and crevices in your attic, creating a tight seal that minimizes air leaks.
- Versatility: Blown-in insulation can be installed in attics of various shapes and sizes, making it a suitable option for many Stockton homes.
Insulation Options and Costs in Stockton:
To help you make an informed decision, here’s a comparison of common insulation types and their average installed costs per square foot:
- Blown-in: $1.00 – $2.80 per square foot
- Batt: $0.80 – $2.60 per square foot installed
- Spray Foam: $1.00 – $4.50 per square foot installed
Knowing these costs allows you to compare blown-in insulation to other options.
Blown-in Insulation Installation Pricing Factors:
The cost of blown-in insulation installation depends on the following factors:
- Location Size: The larger the area being insulated, the more materials and labor time are required. T
- Insulation Type, R-value, and Thickness: Higher R-value insulation costs more. More depth and thicker layers of blown-in insulation also require more material, impacting the price. Choosing the correct R-value for Stockton’s climate matters. That’s why we recommend R-38.
- Current Insulation: A home with existing insulation that has settled but is still in good shape requires less new insulation than a house needing complete replacement. This can affect both material and labor costs.
- Old Insulation Removal and Disposal: It adds to the cost if old insulation needs to be removed and disposed of.This service costsy $1 to $2 per square fooe.
- Air Sealing: Air sealing between the attic and living space costs $350 to $3,000, depending on the job’s complexity, including ductwork, fans, and ceiling fixtures. Some contractors include air sealing in their estimates, so it’s essential to clarify.
- Roof Vent Installation: Installing a roof vent costs $200 to $700. Any vents exhausting air from the home into the attic must be vented outside before installing blown-in insulation. This is crucial for proper ventilation and moisture control.
- Cleaning & Hazard Removal:
- Attic cleaning costs $100 to $600+.
- Attic mold removal costs $1,500 to $15,000+, depending on the extent of the damage.
- Asbestos removal costs $10 to $25 per square foot. Asbestos testing costs $250 to $850.
- A pest inspection costs $40 to $150. Pest extermination costs $135 to $200 per visit.
- Drywall Repair: Drywall repair costs $100 to $400 per hole. Insulating existing walls requires drilling holes in the interior drywall or exterior sheathing, which may call for repairs.
