When you add insulation to your home, you’ll not only enjoy a more comfortable home throughout the year, but you could also save on your monthly heating and cooling bills.

Here’s what you need to know about the cost to insulate, the types of insulation available — along with which areas of your home you’ll get the most bang for your buck by adding insulation.

The Cost of Insulation

Insulation costs are variable and depend on:

  • The climate in your part of the country
  • The style of your home
  • Existing insulation that needs to be removed
  • The age of your home
  • Other factors

Standard Insulation Costs in Massachusetts

These price ranges are estimated and will vary depending on the size of your home and its condition. The bigger the home, the greater the cost.

  • Wall insulation: $500 – $1,500 per floor depending on the square footage
  • Attic: $500 – $2,000 depending on existing insulation
  • Basement : $500 – $2,000 depending on removal requirements
  • Crawl Space: $150 – $2,000 depending on removal requirements

Insulation Cost for Older Homes

Older homes are more expensive to insulate then new ones, as there are more opportunities to improve leaks and other conditions. There may be additional road blocks such as knob and tube wiring that need to be removed first. As a result, the entire house may need to be rewired at a cost which could run in the thousands. Vermiculite in the attic may also need to be removed – which could be pricey. However, insulation makes an older home comfortable, sellable, and energy efficient. In addition, Mass Save rebates may help those who are considering insulating an older home.

Different Types of Insulation and Their Costs

Choosing the right type of insulation depends on the room or area of the home you are insulating, the climate in your part of the country, and your budget.

  1. Fiberglass Batts. As one of the most inexpensive types of insulation, fiberglass is relatively easy to install in attics and crawl spaces. However, it may be difficult to add to existing walls without tearing out drywall.With an average cost of about $1 per square foot, fiberglass is the least expensive option. However, it will deteriorate quicker than other choices over time. You’ll also only receive the best value with proper installation as a loose corner or tear will reduce its effectiveness.
  2. Reflective or Radiant Barrier. This type of insulation is perfect for blocking out the sweltering summer heat and winter chills in your attic. When combined with another insulating method this type of insulation is great for reflecting heat.With an average cost of around 30 cents per square foot, a radiant barrier is inexpensive, but you’ll need to add another type to protect against the harsh conditions of a New England winter.
  3. Blown-In Insulation. Made from recycled paper, cardboard and other paper products, blown-in insulation is an easier way to add insulation to existing spaces with minimal disruption to the home.
    Blown-in insulation can be a DIY project, but professional installation is recommended to get the best results. For a professional job, you can expect to pay around $1.30 per square foot.
  4. Spray Foam. This type of insulation offers double-edged protection from harsh weather by insulating your home while also sealing up gaps and cracks to stop air leaks.The average cost per square foot is around 50 cents per square foot for open-cell, or $1.50 per square foot for closed-cell which provides a superior insulation job. Although the price is a bit higher than other types of insulation, you can save as much as $500 per year in energy costs with the added benefit of sealing up air leaks.

Where to Add Insulation

The most important place to insulate is your attic, as it’s the easiest place for expensive heated and cooled air to escape the home. If your budget only allows for insulating one area, this would be it.

Walls are another essential area to insulate and seal air leaks. If you’re insulating existing spaces, blown-in and spray foam will allow you to easily add insulation through small holes cut into the walls.

Once these key areas are well insulated, other areas to consider are garages and crawl spaces. You’ll need to make sure both areas are ventilated and free from moisture for optimal performance and to give your new insulation a long life.
