The work that Green Stone Energy completed at my home was awesome! The crew arrived as scheduled and completed their work in the most timely manner. They were very neat and made sure to clean up after themselves. I couldn't believe that the owner of the company even came to check on the progress of the crew and went through the whole process with me. Would definitely recommend Green Stone Energy to others - such a pleasant and hassle free experience.

Greenstone Energy first did a thorough energy assessment of our home.Then they sent a phenomenal crew to insulate our attic, replace the baffles, box in all our many recessed ceiling light fixtures and insulate all the outside walls of the basement.The crew was professional, and answered all our questions.The job was done on schedule and the cleanup thorough!We would recommend them to others without hesitation.Thanks for a job well done.Joe G.

Our central air conditioning wasn't keeping up on hot summer days. After a PECO energy audit showed we didn't have enough insulation in our attic, we hired Green Stone Energy to add insulation and perform blower door testing and guided air sealing (finding areas around windows and exterior doors that need caulking). The crew was professional and explained what they were doing as they went along. They finished the work in seven hours. The first day after Green Stone completed the work, we noticed a difference in our AC. The AC now keeps up and doesn't run nearly as much. This has been a huge improvement to the energy efficiency of our home. I'd highly recommend getting a PECO energy audit and if additional insulation is recommended, hiring Green Stone Energy to perform the work.

We contacted Green Stone Energy after a PECO energy audit showed a lack of insulation in our attic. Everyone was very professional, friendly, prompt and did a quality job for us.

They arrived when they said they would. spread drop cloths where they would be walking. The owner stopped by to check on the progress. All went well. It took about 8 hours from start to finish. My initial observations are showing a positive improvement in the houses ability to hold temperature which is an increase in overall comfort. It is too early to determine a dollar savings in gas and electric usage. I would recommend and use them again. All were very nice to deal with.

Thank you Dutch and Christian from Green Stone Energy LLC for a job well done. Our family will be feeling much warmer this winter. No more heating the outside.
