Frequently Asked Questions?
How long does blown-in insulation last?
Blown-in insulation typically lasts 20 to 30 years or longer when properly installed and kept dry. Its lifespan depends on moisture exposure, air leakage, pest activity, and material settling. Regular inspections help confirm performance and identify when replacement or upgrades are needed.
Can blown-in insulation be added on top of existing insulation?
Blown-in insulation can be added on top of existing insulation, most commonly in attics. This method increases total R-value and improves energy efficiency without removing insulation that remains dry, clean, and evenly spread. Existing insulation must be free of moisture, mold, pests, and damage before new material is added.
Does blown-in insulation help with noise reduction?
Blown-in insulation helps reduce noise by absorbing sound waves and limiting sound transmission between rooms and from outside. Its dense, gap-filling structure blocks airborne noise more effectively than many traditional insulation types. Homes near traffic, mechanical systems, or multi-story layouts often experience noticeably quieter interiors.
Will blown-in insulation make my home too tight?
Blown-in insulation does not make a home too tight when installed correctly. It reduces uncontrolled air leakage while allowing proper ventilation systems to manage fresh air and moisture. With correct attic ventilation and air sealing, homes maintain healthy airflow, indoor air quality, and balanced humidity levels.
Is blown-in insulation safe for my home and family?
Blown-in insulation is safe for homes and families when professionally installed. Modern materials meet building and fire safety standards and often include fire-resistant and pest-deterrent treatments. Once installed, insulation stays contained in walls or attic spaces and does not affect indoor air during normal daily living.
How is blown-in insulation different from batt insulation?
The main difference between blown-in insulation and batt insulation is installation and coverage. Blown-in insulation fills gaps and irregular cavities for consistent coverage, while batt insulation uses pre-cut panels that can leave voids if not perfectly installed. Blown-in works best in attics, older homes, and obstructed spaces.
Can blown-in insulation be installed in all types of homes?
Blown-in insulation can be installed in most types of homes, including older houses and homes with finished walls. It works best in attics and enclosed wall cavities. Suitability depends on framing, moisture conditions, ventilation, and existing insulation, which a professional evaluation can confirm.
What preparation is needed before installing blown-in insulation?
Prepare for blown-in insulation by inspecting attics or wall cavities for air leaks, moisture damage, ventilation issues, and existing insulation condition. Complete air sealing before installation to improve performance. Proper preparation increases energy savings, prevents moisture problems, and extends insulation lifespan.
Reviews from our customers over 48 years
Nealon did an outstanding job in terms of courteous services, as their team members, as well as Chris who was responsible for directing the job, were most professional!!! They cleaned up nicely, and my goods remained intact. Also and happily stated, it’s been one week since they’ve installed insulation in our home, and we notice a huge difference in the amount of energy we are using for heating…which equates to $avings!!! In short, we’d use them again, and glad we chose them for this endeavor!!!
Highly recommended. Their estimate was competitive, the work was done in a timely and clean manner, they explained what was done, and our house is warmer as we head into the winter. When we had a question, they came back out to talk with us and helped us answer our questions. I will use them again and recommend them to anyone.
They are an amazing company to do work with! Jen in the office is polite, pleasant, and very competent. The work was done well and very quickly. We had our attic and basement insulated. I would 100% recommend!
The Nealon team was professional and considerate of my property. I noticed a 200-kilo watt decrease in my electric bill along with an additional savings in oil consumption of 50 gallons. No more drafty cellars and so far, the mice have gone elsewhere.
Fast, efficient and great price! Didn’t even notice them insulating our attic and making a big difference already! Would highly recommend for anyone that wants to cut down on their energy bill!!
