Rook Energy was very helpful and professional in identifying areas for improvement at a new home I purchased. They concentrated on the areas I would get back the most savings. Their suggestions for improvements have paid off. They work with you and your budget to get the most for your dollar. Excellent communication and quality work.

I recommend Rook Energy Solutions. They were very professional, and completed the job on time. We have been pleased with the results, especially on very cold days!

Bar none the best thing I have ever done.. I give Rook a 5 star rating and would not hesitate to recommend their workmanship and efficiency to anyone who would ask for a reference. I have recommended Rook to several of my friends and acquaintances who in return had work done.

“Rook Energy Solutions was very thorough and accurate in their assessment. Their recommendations were spot on and saved us money. I would not hesitate in recommending Rook Energy to anyone looking on how to make their homes a better place to live.
— Ara M. - Freeport, ME
The energy audit they preformed provided us with a wealth of information. They were professional and most helpful. By fixing several of the problems ourselves we have noticed a huge difference in our ability to heat our home more efficiently. Wish we had hired them years ago.
