    "Bob & his team did an outstanding job installing insulation upgrades & attic fans in our home. Bob quoted us a very fair price & treated us exceptionally well. Bob quickly informed us of an energy rebate offered by City Public Service & as part of his services, he will complete all the necessary application requirements online for us. This rebate will be over $500 - two other bidders did not even mention the rebate program! HouseRangers will be our go-to first choice for all insulation work for our familyâ s homes."

    "Zeke was a pleasure to work with from the get-go! His presentation during the phone interview was everything you want to experience from all service companies, and his attitude was so refreshing, given I had already talked with a couple of other companies who seemed to come off as though my business was not so important. And as promised when we booked the job, Zeke called ahead to say he was on the way, and was on time as scheduled! They immediately got work, and even helped me remove some items from the attic to get clear his work area. Within an hour & 15 minutes after starting they were finished! Zeke, Louis, and Charlie did an amazing install, and I wound up with more than I expected, and given their quality materials and workmanship with the job, I could not be happier. And by-the-way, the price was amazing ~ 60% LESS than the "named" competitors who quoted it as well. I guess they are more interested in selling me radiant barriers, windows, etc etc... which would explain why they all told me it would take 4 - 6 hours to do the same job Zeke and his crew did in less than 2! Thank you Zeke, I truly appreciate your work, and I have no doubt your business is going to succeed beyond your expectations."

    "Eric extermely professional and caring explained everything about insulation in the attic. He was very patient and made sure I understood everything. I feel very fortunate that I came across this Insulation Company. Eric, Phillip & Daniel all came out and did everything they said they were going to do. They also took pictures after they completed the job to show me the other parts of the attic I could not get to in order to help me see that they did what they told me they were going to do. If you want people you can trust, as I did they I would tell you to go with the Green Faith Solutions to ensure you get what you pay for. Thanks, Albert"

Frequently Asked Questions

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?

+

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?

+

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?

+

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?

+

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.
