Taking a whole-home approach to energy efficiency sets Alligood Energy apart from standard contractors.
Instead of just spraying foam, they utilize advanced diagnostic testing like blower doors and infrared scanning to pinpoint exact areas of energy loss before starting any work.
They also offer both spray and injection foam, which allows them to insulate finished spaces without major demolition.
I recently spoke with a neighbor who used their end-to-end service, and they were particularly impressed by the lifetime guarantee on the products.
Be aware that some communication regarding post-installation finishing can be inconsistent. You might need to proactively request specific dust control methods or handle minor patching reworks if the initial spackle fails to cure quickly.
Made a huge difference
I had a great experience with Alligood Energy. I got my attic insulated with 4” closed cell spray foam which made a huge difference in my heating. Thank you Andrew!| Google Review
Had Alligood Energy come out to do some blow in insulation in my roof, we soon discovered that I had absolutely no insulation in my roof and they were able to dense pack the entire available area. The difference is night and day, I’m noticing a 40% reduction in heating and cooling cost. I do have a Philadelphia row home, so most of my exposed envelope was the roof.

A terrific experience
We had a terrific experience with this company. They first came to our house to do an energy audit and then spent a lot of time with us answering questions and giving us options. They helped us convert our house to gas, replace our boiler, and insulate our attic. The whole process was painless thanks to them. The monthly cost for all of the work they did is less than how much we used to spend per month on oil alone. I would highly recommend them.

Unfortunately, their post-project cleanup and finishing quality sometimes leave a lot to be desired. You might find yourself dealing with worksite cleanliness issues or needing to handle minor structural repairs after their team departs.

The best and cleanest spray foam job
AGL Spray Foam did an incredible job at my house. John came out and walked through the house offering his recommendations, and he sent a proposal to me a few days later. He showed up to do the work when he said he would, and finished 1 day ahead of schedule. His crew was very professional and helpful when I walked through the house before they were finished. My general contractor also commented that this was the best and cleanest spray foam job he has ever seen. I HIGHLY recommend using AGL!

Did a great job
Had AGL come in install (spray?) closed cell sprayfoam on a new 1500sq/ft pole barn. The guys professional and friendly, on time, did a great job and cleaned up after themselves. Definitely recommend them if you’re looking for spray foam insulation in the mid-Atlantic.
