"The crew worked quickly and efficiently to replace and upgrade the fiberglass batts in our basement and crawl space. I’m pleased with the outcome. (I put in even more wire supports afterwards — to secure the insulation between the joists — but that’s just my OCD.) It was a relatively small job for this company and I thought the cost was fair."

About 15 years ago Jairo Urena started a general insulation business known as SONO Sprayfoam Insulation in the city of Norwalk, CT. For many years we have performed a wide variety of work, including new and existing construction. From our beginnings, we saw the need for a quality spray foam insulation service in our city as well as New York City and New Jersey and started researching it, and soon we completely shifted our focus to the insulation and derivatives business. Today we are a small family business with good roots that operates in Norwalk and the surrounding counties. We can spray isolate residential, agricultural and commercial spaces. and the waiting time is generally minimal.

"Great job, quick and competent! Made a difficult job easy. Have used this service several times, always happy."

Blown in insulation install or upgrades FAQs

Blown-in insulation offers several advantages over traditional insulation methods. This insulation option is fire-resistant, long-lasting, and more energy-efficient, providing superior thermal regulation for your home. Blown-in insulation fills gaps in walls and hard-to-reach spaces effectively, reduces noise transmission, enhances indoor comfort, and can increase your home's overall resale value.

Installing blown-in insulation in a 1,500-square-foot house costs between $2,625 and $11,250. Your total cost will depend on the type of insulation material you choose, labor rates in your area, and any additional work required, such as mold remediation or electrical adjustments. Hiring an insulation professional ensures proper installation, and labor costs typically range from $40 to $70 per hour. Getting detailed quotes can help you budget accurately for your project.

The cost of spray foam insulation ranges from $0.45 to $1.50 per board foot, while blown-in cellulose insulation costs between $0.60 and $2.30 per square foot. Spray foam insulation is less expensive per unit and offers excellent air sealing properties with higher R-values. Blown-in cellulose, made from recycled materials, is slightly more expensive but provides superior soundproofing and is environmentally friendly. Choosing between the two depends on your specific insulation needs, budget, and preference for eco-friendly materials.

Blown-in insulation is generally cheaper to install than batts. Batt and roll insulation can cost up to $2,500 on average, whereas blown-in insulation often results in cost savings due to lower material and labor expenses. Additionally, blown-in insulation fills gaps and irregular spaces more effectively, improving energy efficiency. Opting for blown-in insulation can save you money while providing better coverage and performance compared to traditional batts.

The best R-value for blown-in insulation depends on the area of your home you're insulating and your specific climate zone. Generally, attics in the U.S. should have an R-value between 30 and 60, with colder regions requiring higher values for optimal energy efficiency. Walls typically need R-values between 13 and 21. Consulting with a professional can help determine the ideal R-value for your insulation project based on local building codes and energy requirements.

Your decision to remove old insulation before installing blown-in insulation depends on the condition of the existing material. If the old insulation is damaged, moldy, or infested with pests, you should remove it to prevent health hazards and ensure effectiveness. If the existing insulation is in good condition, you can often install blown-in insulation over it to increase R-value and improve efficiency. Consulting with a professional insulation installer can help determine the best course of action for your specific situation.
