Areas Of Expertise: Foam Injection Insulation - Install, Wall Insulation, Retro-Fit Foam Insulation for Existing Homes , and 2 more
"These people are great. On time, extremely clean, very professional. They cleaned out the old insulation from our attic, disinfected the entire space, sealed any holes, placed covers over all recessed lights in the attic to prevent heat loss from the second floor into the attic, and weather stripped the pull down stairase into the attic to prevent heat loss there as well. We used cellulose insulation which can be very dusty. Not with these people. They cleaned everything including the driveway. They are superb."

"They did a great job. Had a small bump in the road at first, but they bent over backwards to make everything right. Matt is great and followed up every step if the way. I love my new attic storage and finally have decent insulation!!! And the guy who patched the ceiling wasn't horrible to look at, so that's always a plus!! :) They were really great about cleaning up and gave me some awesome tips for some DIY stuff I wanted to do. I tried to stay out of the way, but couldn't resist asking a couple of questions here and there so I wouldn't completely screw up my house when I got brave and decided to do something myself!! Would definitely recommend them and will call them again when I have another big project that I need done."

"They also did insulation in our attic , the roof was done in 1 day which is standard and the workers were very efficient and cleaned up very well after themselves. Everything from beginning to end was top notch , the company went above and beyond from the thank you card we received shortly after signing up with them , to a detailed letter of what to expect . Our roof was installed within 2 weeks, and the insulation was done a week later. We were kept up to date with the progress of each part of our projects. We would highly recommend them and will be using them again for more work we need done. Thank again"

"Definitely choose Terra Insulation! Josh, Dylan, and Brandon were all fantastic to work with. They removed existing insulation in two attics that was covered in mouse droppings, sanitized both, added baffling, sealed holes, blew in cellulose insulation, and sealed all entry points. They explained all the options and pricing clearly, gladly answered my MANY questions with patience, took care of the rebates with the utility companies, which significantly reduced the total cost, were super flexible with scheduling, very clean, and professional. There were no surprises or hidden costs. I was extremely happy with Terra's workmanship and professionalism and would hire them again without question."

"Very courteous, efficient and knowledgable. The details of the project were fully explained and the cost was reasonable."
Stephen L. in April 2022
Areas Of Expertise: Spray Foam, Home Energy Audits, Air Sealing , and 2 more
"This company is very professional and performed a great job. They insulated my attic and basement crawl space. They installed exhaust fans in 2 bathrooms, they installed weatherproof stripping at 2 entrances and sealed all ducts. Today it is 13 degrees outside and the difference from last winter is mind blowing. From the top floor to the basement level the vents are blowing consistent warm air, all rooms are comfortable and I can walk around bare foot. At the end, they even helped me apply for the rebate from Balto Gas and Electric. The final proof will be in my G&E bills. I expect to see some savings."

Frequently Asked Questions
What is insulation?

What is insulation?
Insulation is material that provides a barrier within a home’s walls, ceilings, and floors to regulate temperature and noise. If your home gets overly hot in the summer and cold in the winter, it’s likely not insulated properly.
Insulation efficiency is measured by R-value, which determines how resistant different types of insulation are to heat flow (or energy loss). R-values are measured by inch of thickness. The higher the R-value, the better the performance and the higher the price.
How much does insulation cost?
+
How much does insulation cost?
Our project data lists insulation costs between $1,400 and $6,300, but your final price will depend on the type of insulation you choose, its R-value, and how much you need.
- Fiberglass insulation: $0.30 – $1.50
- Blown-in insulation: $1 – $2
- Spray foam insulation: $0.50 – $2
- Radiant insulation: $0.20 – $1
- Rigid board insulation: $0.25 – $1
Luckily, insulation is one of the best investments you can make in your home—it has an ROI of at least 100%, meaning you’ll likely make back what you spend in a few years or so.
What is insulation made of?
+
What is insulation made of?
Insulation is made of many different materials, which can also impact the R-value needed for energy efficiency.
- Fiberglass: The most common insulation material made from glass. Fiberglass is a skin and lung irritant, so you’ll need to wear gloves and clothing when working with fiberglass insulation.
- Cellulose: Made from recycled paper products, plus borate for fire and insect resistance.
- Foam: Made from polystyrene, polyisocyanurate, or polyurethane plastic. You can also install cement-based foam insulation using rigid foam boards.
- Mineral wool: Made of fire-resistant rock wool, a mix of natural materials, or slag wool, made from a molten metal product.
- Natural fibers: Made from various recycled natural materials, including cotton, sheep’s wool, and straw.
Where is insulation in a house?

Where is insulation in a house?
If your attic is unfinished or you’ve ever demolished an interior wall, you might notice batt or spray foam insulation between the studs. Putting insulation between your walls and floors helps keep your home comfortable and your energy costs down. In addition to walls and attics, you can install insulation in your garage, in floors above vented crawl spaces, and basements.
- Garage Insulation: $0.50 to $1.25 per square foot
- Floor and crawl space insulation: $1 to $5 per square foot
- Basement insulation: $1.50 to $2.50 per square foot
- Wall insulation: $1 to $4 per square foot
- Attic insulation: $1,500 to $6,000
- Roof insulation: $1,500 to $4,500 or more
What are the different types of insulation?
+
What are the different types of insulation?
There are a few types of home insulation, and they all are made of different materials— most commonly, fiberglass, cellulose, and foam. Insulation includes these materials in the following forms:
- Loose-fill: Also called “blown-in,” loose-fill is sprayed into wall cavities, attics, and other oddly-shaped areas using special equipment. This insulation is usually made of fiberglass, cellulose, or mineral wool.
- Batts: An affordable insulation blanket best for unfinished spaces, such as between framing, studs, or joists. They come in pre-cut sections suitable for DIY installation and are mostly made from fiberglass, though other versions are also available.
- Rolls: Similar to batt insulation, but comes in rolls. Its make-up leaves less chance for gaps between sections and is more efficient than other types.
- Foam board: One of the most popular insulation types that can be used almost anywhere in your home. Foam boards also have a high R-value.
- Spray foam: Expands and hardens to fill gaps, small and large. Can be closed-cell or open-cell, but closed-cell has a higher R-value, making it more expensive per square foot.
- Radiant barriers: Does not reduce heat flow but directs heat away from the home instead. Radiant barriers are DIY-friendly and affordable, but they won’t be as effective in the winter months.
