We take a whole house approach and offer a free 12 point energy audit to help improve the efficiency of your home and reduce your carbon footprint. We inspect everything from your crawl space to your attic, making recommendations on how to make your home more energy efficient. We specialize in installing radiant barriers in attics that blocks 97% of the radiant heat. Whether it's the radiant heat trying to leave your home in the winter or the radiant heat coming in through your roof, either one is bad for your wallet. There is no other home improvement project that can offer a return on your investment as quickly as we can. Here at All About Energy Solutions we are all about customizing energy saving packages to meet our clients needs. If you just want us to seal your attic air leaks and bring the insulation up to code, we can do that, but we prefer to offer complete packages. We can also remove attic or crawlspace insulation with ease with our machines. Remember at All About Energy Solutions we are increasingly green, but always red, white and blue!
"Fast, reliable and excellent work. Andrew and his team did an amazing job with our addition installation. Thank you All About Energy Solutions."

When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:
Blown-in: $1–$4 per square foot
Spray foam: $2–$5 per square foot
Batt: $2–$4 per square foot
Structural insulated panels: $4–$7 per square foot
Loose-fill: $2–$5 per square foot
Reflective: $0.50–$1.50 per square foot
