"Jorge and his team helped me remove and replace installation in my mobile home crawl space, as well as sanitization and rodent proofing. They went above and beyond to ensure the work was done at the highest quality and to the fullest satisfaction of my family. My mom noticed some areas that needed additional work outside our original contract, so Jorge came back the next day on his day off to do it for free. I would recommend Jorge and his team for your insulation needs."

Without home insulation, homeowners face cold winters, hot, sticky summers, and roof rats crawling into their walls. Without insulation, more greenhouse gasses escape your home, contributing to an ever-increasing cycle of more dangerous and unpredictable weather and even wildfires and flooding. Closer to home, your children suffer from more allergies. The fight to keep your home clean includes battling dust and unsightly mold. Vortex Insulation was born out of a desire to give you the home team advantage and help you win the fight. We elevate the home insulation experience from a necessary chore to the feeling of protecting, securing, and stewarding your home and the environment. Our insulation techniques are customized to each home, requiring little or no construction. Choosing the right products can be confusing even for some contractors, so we created a simple system. Our free evaluation is the most effective way to identify what needs to be done at your home.

"Very messy project. Just be prepared. While inside my house plastic and tarps covered everything. And place was clean after work done. I have 2 attics. The other is on the garage. I didnâ t think that I should have asked for tarps to cover the stuff in my garage. There is fine particulate matter everywhere! Will take me a long time to return to normal. Not their fault but mine. Showed up on time, worked hard, insisted I climb in attic to see what they had done. My house and the lawn â stagingâ area was immaculate after they left. Highly recommend them."

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.
