"I recently had the pleasure of working with H&L Insulation that was hired to blow fiberglass insulation into my attic, and I couldn't be more impressed with their professionalism. From the moment he arrived, he was punctual, courteous, and well-prepared. David took the time to explain the process to me and answered all of my questions patiently. He worked efficiently and meticulously, ensuring that every corner of the attic was properly insulated. He also made sure to clean up thoroughly afterwards, leaving no mess behind. Overall, his attention to detail and commitment to quality were outstanding. I highly recommend their services to anyone in need of attic insulation!""

"Claudio and his team did the blown insulation in my attic today and they did an AMAZING JOB; I am very happy with their work. He is very professional and answered all my questions from start to finish, he arrived at the time he said he would and cleaned up to a point that you would not even know they were here. :) I would most certainly refer them I would give 10 stars if I could. I got two other estimates, and his price was by far the best!"

"Kendrick and Allen installed blow-in insulation above a bedroom ceiling in my condo in May-2016. These two guys were polite, prompt, professional and cleaned up when they were finished. I feel like I got a fair price for a very provfessional job. I would highly recommend calling them for insulation work.."

Insulation FAQs, answered by experts

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures. 

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.
