Areas Of Expertise: Foam Injection Insulation - Install, Wall Insulation, Retro-Fit Foam Insulation for Existing Homes , and 2 more
"From beginning to end, they are completely professional. I have no reservation giving them 5 stars across the board even though our experience wasn't the smoothest. Keith and Meran came by for the estimate and evaluation. Very professional, very knowledgeable and did not pressure sell us. Very fair and reasonable quote for attic insulation. We scheduled our installation and the install team came at 6:30p with a 1p-5p install window. Because of the late time and the amount of work, it wasn't finish that night. We were disappointed and a little frustrated, but then the company shined. They came back on a Sunday to finish the install (they don't do installs on Sundays), gave us a discount due to the issues with the original install. Jimmy and Philip were the install team and they were very professional and you can tell they take pride in their work. I 100% recommend them and will be using them again when we can budget in a job to insulate our basement."

Service Pros
"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."

"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."

"Did our roof, gutters and also our attic insulation !!! House looks great , and we now will feel more comfortable going into the winter. They came out within 1 week to replace the roof and gutters and had them done within one day . The insulation was done a few days later and we instantly felt a difference in the comfortability in our house. They also had great finance options which delayed any payments for 6 months which give us a break !!! Thanks again Elite"

"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."

"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.
