Alligood Energy is a result of 35+ years in the energy sector providing renewable energy solutions for military bases, nuclear facilities, universities, hospitals and residential housing. We have taken that experience to create a very unique and specialized company that provides energy auditing and consulting to the residential, commercial, industrial and institutional markets. For our customers we provide a whole house or building approach to energy savings that uses the latest technological equipment to identify where and how a home is losing energy, which systems are working inefficiently (heating & cooling, ventilation, etc.) and propose the most cost-effective solutions to rectify these problems to lower your energy impact. ***** We offer a $175 Home Energy Audit - Using a blower door and thermal imaging, our 1-1.5 hour whole house approach pinpoints costly energy problems and proposes effective solutions for improving savings & comfort in your home. If you are interested in implementing the solutions after the audit we also perform the work & run a test out upon completion to measure the improvements.

"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

"I wished if it were be able for me to give this company more than 5 stars for my review. Right after I realized that we have Raccoon residence in my attic I sent an email at midnight to Attic Fanatics. I got a call at 8 from Coby who said someone will come within a hour. Mike Bruer showed up on time and did a thorough inspection. He advised me that the Raccoon may have been in my attic for awhile. I decided to replace all insulation. He provided me a reasonable quote which I accepted right at the spot. He also helped me to file a claim with my homeowner insurance company. On the very next business day there was a crew of 5 people showed up on time. They are very professional and did a neat job. Being a picky person like me I am totally satisfied of their work. They sealed the openings to prevent the Raccoon from return. After they left I found out there is one Raccoon was still in the attic so they came back right away and chased it out then resealed the soffit vents with heavy gauge mesh. Great job!"

"Trenton Roofing is simply an amazing company from start to finish. 1.5 years ago I did a roofing project with them and Brian the technical sales rep did not do the typical U.S. sales approach by sitting together and putting pressure on you to make an immediate decision. He even did his measurements while I was absent and just sent me over a quote which I directly accepted and the work was again done while I was on vacation. Totally great job and everything was handled with car. At that time I also asked for an estimate for new gutters but I wanted to have them replaced AFTER the solar panels have been installed again and this year I wanted to get it done.I used the old quote, placed the order, got confirmed but - and now the best - within the 72 hours cancellation period I decided different and I just met Brian without any hard feeling from his side we cancelled the job and my down payment was immediately reimbursed! What an outstanding attitude!For my siding project the bid is your!"
