AWC Energy
AWC is a leading energy services company that provides a full compliment of services. We offer consulting services, general contracting, full scale integration, installation, sustainability services, and cost-effective energy solutions for commercial, industrial, residential, retail and non-profit customers.
"Lomont and his team were great to work with, simply professional, knowledgeable and so accommodating. I hired him based upon an energy audit we had done by another company. He basically "cleaned up their mess" since they did not do a thorough report in order for us to get our energy rebate etc. He went above and beyond the scope of what we hired him to do, always with a friendly greeting and smile. He reached out to the appropriate agency to push to get the credits we were due and did work that should have been done by the energy audit company. I highly recommend Lomont."

"Jeff and his team did an outstanding job on our roof. They use high quality materials, warranty their work and are cost competitive. The team tore off our old roof (2 layers) and replaced it with new architectural shingles the next day. They cleaned up each day and were vigilant in chasing down any roofing nails that may have landed in the yard using a magnetic sweeper. They worked with us to get the 2 hot water solar panels decommissioned and removed them from the roof as part of the job. The house looks better than ever and we couldn't be happier with the work. We would use them again and will wholeheartedly recommend them to anyone doing general contracting or roof replacement."

FAQs for insulation service projects in South Windham, CT
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
