"I live in a condo building and I was unsure the last time the dryer vent was cleaned. When they finished, they told me to call the back if I continued to have problems. When I needed to call them back out, they came the same day and worked until they found what was blocking the vent. I was impressed at his persistence and making sure I was completely satisfied.

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.
