"I highly recommend TLS. They were very professional & best priced out of 3 quotes I received for new insulation in my attic. They showed up on time and completed the work as described. The owner stopped by to check on the job which rarely ever happens with contractors nowadays. I am extremely happy and satisfied with my choice of TLS and their work. Thank you!"

"Fair price an on-time service. But I should have checked the job..... there were a few spots in the attic that did not get any insulation. (not the garage..... that does not need insulation..... but a few spots over heated space were not covered). But their price was better than other estimates. I also requested the chemical that detracts rats and mice..... I do not know if it was included...... I hope so."

"Armada Insulation was fast, efficient and easy to work with. They did quality work and had competitive rates. They did the crawl space insulation for us and said they would come back if we needed anything fixed. I don’t anticipate that need, but appreciate the accountability. I recommend them for insulation."

"They came out to inspect my property. They told me I didn’t need their services and my house was insulated more than enough. They could’ve sold me the world, instead they were extremely honest and polite. Their prompt and professionalism is unsurpassed and I would recommend them with all my heart"

"Newer to the sunshine state and was frustrated with my electricity bill and the feeling like my AC was constantly pumping but there was always lingering humidity and I never felt truly cool. Had Danny come out and discovered the temps in my attic were upwards of 135 degrees, and that my existing insulation was allowing the heat to transfer into my home. His team removed my previous insulation, sealed the gaps and cracks , and installed new insulation. My home feels now feels more comfortable and I’m seeing a reduction in my energy costs. As a single female homeowner, I was skeptical that I would be taken advantage of and the cost would be exorbitant. The entire experience was comfortable, unpressured and professional. Highly recommend Heat Hunters’ services!!"

Insulation FAQs, answered by experts

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.
