"We had insulation installed a week earlier by Koala. During the insulation, Jasper (insulator) suggested another area that we might consider installing blown-in insulation. We agreed and the second job was performed on Friday, the 24th. Jasper and Richard were on time, the insulation project was well done and they left the area very clean. Would use them again."

"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"They took the time to explain the options and inform my decision-making. They answered all of my questions with patience and good humor. I believe I have received great value for the money I have spent. They were flexible when I wanted to make a change once work had begun. Since the house has been air sealed and insulated we have been warm and comfortable. I highly recommend Terra Insulation for your insulation needs."

"Prompt, courageous and provided exactly what I needed. There was little to no insulation nor room in the attic. I priced it out and started to wonder ‘..can I really do this job myself?’ Maybe 10 years ago but the price for Pink blown- in insulation was so good- I couldn’t afford not to have Home Genius Exteriors do the job. I am so happy to see that beautiful sea of pink insulation. Kudos"

"Our first interaction with Atlas was with Shannon. As knowledgeable and personable as one could hope for. She clearly explained cost effective measures to better insulate our house. We opted for sealing and insulating our attic and weather stripping a number of doors. We were very pleased with the workmanship and the energy savings they produced. They also helped us get a PEPCO credit which reduced the overall cost of the job. A winner!"

"We had Xanvria remove the old insulation in our attic, air seal the attic, and install new R-49 batts. They did a really good job, were professional, and explained what they were doing along the way. Everything came out clean and we?re very happy with the work. I would definitely recommend them."

"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end  instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.

With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.

Insulation FAQs, answered by experts

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.

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.

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.

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

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
