Energy Savings for Us

I thought you might be interested to know that the night following the insulation work you and your crew did in our attic Tuesday, the temperature in most of the house (except the addition) only went down to 62F, even though the outside temperature was below freezing. This means that the heating system probably did not turn on once, since we set the thermostat at 60F every night. That has to start translating into energy savings for us.

Professionalism & quality of work

I wanted to take this opportunity to thank you for providing me with the name of Fifth Fuel as a contact for insulation work for my house. During November, I had Adam Letcher do extensive insulation work (reflective insulation in knee wall areas, spray foam, blown in loose cellulose and extra insulation over drywall doors). The professionalism and quality of work done by Adam and his crew was excellent. I would highly recommend him to anyone who is considering this type of work on their house.

Couldn’t be more pleased

I just want to take a minute to let you know the guys showed up on time yesterday, stayed late and did an awesome job! I couldn’t be more pleased with the outcome.

Please make sure the guys and all their supervisors know that I can’t thank you all enough for the superb job. I will be giving your name and number to everyone I know with the highest recommendation. And will call you back to look at my house.

No more drafts

I wanted to take a moment to follow-up with you on your work in our home this spring. As you predicted, it did not take as much work for our AC unit to cool the house and it seemed to hold the temperature better. Although we have not had a cold winter thus far, we find our kitchen to be far more comfortable (that has always been a problem). No more drafts and the heater under the bench at the table to keep us comfortable. The foam insulation sealed that space up nicely. The basement also holds a nice, even temperature.

I am most grateful we found you. Your expertise and knowledge was most helpful for our project. Thank you for your patience with all our questions and taking the time to explain things in detail at times.

Timely service & quality of the work

I would like to thank your staff for the timely service and quality of the work that was performed on my personal residence. The office staff has been very helpful with anything that was needed and the crew went above my expectations. They arrived, completed their work, and left my house cleaner than it was when they got there. I would recommend your company to anyone that needs insulation work done on their home.


Couldn’t be happier!

I just received my March/April electric bill…and couldn’t be happier! I attribute your design and installation of the insulation package for much of the savings. I would recommend your team to anyone building a new home or renovating an existing home for superior quality and professionalism.

Lance Lewes - Washington, DC

I’m really impressed

Thank you for being so prompt. I can’t tell you how pleased I was to have someone with your knowledge and expertise in charge of my project. You delivered everything you promised and I’m really impressed. Thanks again for coming through. I will gladly recommend you and your company.


Your guys have been the best

We would like to thank you for the work you have done for us. It was done efficiently and very professionally. As victims of Hurricane Sandy, we have had quite a few contractors to our house and thus far your guys have been the best.
