Technicians did a good job. However customer service and paperwork is horrible.They are Peco authorized contractors, and if you get any Peco recommended job done by Green Stone, Peco promises to provide a rebate. Green Stone did the job and left without completing the required paperwork. Since Green Stone needed Peco’s commission for recommending customers, they called me to get my verbal approval for completing their side of paperwork. However, Green Stone, never submitted documentation, which shows calculations showing my rebates to which I was entitled for, therefore I never received my rebate check.

I cannot recommend Green Stone Energy enough! We recently had them do spray foam and batt insulation and they were wonderful to work with. Extremely efficient and scheduled me quickly for both the quote and work. I even forgot to have them spray a small closet in our basement and they came back to do the job. I am very happy with their work.

Green Stone Energy performed attic weatherization in our home (which is electric-heated). We had a great experience with them - they worked carefully and efficiently, and took their time to explain everything to us. It was very convenient to get the PECO rebate by working with them, and we have already notice less heat escape from our home.

Very impressed with the company. We used Green Stone Energy to add insulation to crawl spaces around a bonus room that sits above our garage and also had them add additional insulation between the bonus room floor and garage ceiling. The work was done in April and as we're coming into the middle of Sept, I can say that the work they did made a dramatic improvement in the temperature of the room. Before getting the work done, this room would struggle on the hot days to cool. Now, in the middle of the afternoon, you can walk in the room and it is nice and cool. The team that did the work was very professional. They arrived on time. The time to complete the work was spot-on to the expectations they salesperson set with us. We couldn't be happier with the work and the value we paid it.

Very happy with my experience working with Green Stone. They were respectful of our home and cleaned up thoroughly after they were finished. There was very minor issue that needed to be looked at after the project was initially completed- and they were responsive about getting it sorted out quickly and without any issue. I was a bit disappointed by the amount of PECO rebates that I received on the total job- PECO certainly led us to believe that we would realize a substantial savings towards this project ... however, it amounted to 10% or less. That said, this has nothing to do with Green Stone, their workmanship or customer service- and would definitely work with them again in the future

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.

Follow up to my original post from March 2022. Since this work was done (3 months ago) I have a couple of issues with the work this company did. On the day they came to the house, the technician told my wife the HVAC vents were not connected properly and CO2 was not being properly vented outside the house. We have since had two different HVAC companies come and inspect the furnace ( at our expense) and they both said there was absolutely no issue. Secondly, within a week after they did the work, the hot water pipes started to rattle loudly every time we turned the hot water on. We called out a plumber and he said the issue was Green Stone packed too much foam insulation around the hot water pipes and that was causing them to knock and rattle, which is still happening to this day. Needless to say we are not happy with our experience and would not recommend them.We had Green Stone Energy come in to supplement the current insulation in our home and identify areas where cold air was coming into the house. Three employees arrived as scheduled and were very professional throughout the day. They covered all the areas of the house where they were working and did a very thorough job of cleaning up afterwards. In addition, all three were very courteous and went to great lengths to point out areas where we would need additional work from other companies. Highly recommend Green Stone!

Dutch and team were great at making our house more energy efficient several years ago. They air sealed our basement and crawI space area and were on time and professional. We noticed a difference immediately, especially in the room right above that area.Dutch came out to help us think through our options and he was very helpful, friendly, and encouraged me to do the work that I could do myself to save money. I always appreciate people that do not try to sell me on extra work and I was thankful for Dutch's honesty. We'll be giving them a call again next time we need work.

I highly recommend Green Stone Energy for your next project. The team worked together and did a professional job of adding insulation to my attic and sealing air leaks in my home. The team showed up on time and were very professional, I was told before and during the job about the process, what to expect and the time it would take to complete. The team cleaned up thoroughly after they finished. I was impressed with the quality of the work and their responsiveness to my many questions about the procedure. I recommend them without hesitation.

Green Stone Energy LLC helped us weatherize a portion of our home following an initial assessment by PECO and then their own evaluation after a site visit to our home. We found them to be professional and a pleasure to work with. Their proposal outlined different options for and listed individual line items for each scope of work. The work crew was courteous, respectful of the property and explained their work before proceeding. We will definitely ask Green Stone to help us wth future work.

High recommend Green Stone Energy. They recently did an insulation job in my upper attic. Erick came over twice to quote me and didn’t complain or ask why I needed the extra validation. He answered all my questions and my sure I was comfortable going forward. The two gentleman that did the work were efficient and took the time to minimize any mess. Erick even at one point came by during the project to check on the progress and a concern he had. He informed me that their was a specific part of job that was no longer feasible to accomplish but he felt confident it wouldn’t be an issue. He then informed me that the cost would be removed from the initial quote. I would have never known the small part of the project wasn’t completed since it would have been buried under insulation. His honesty and the quality of the job will be why I plan on being a repeat customer.

I had a great experience with Green Stone Energy. Estimate was clear and on time, workers arrived on time, introduced themselves, all work was excellent and as described in estimate. Workers even repaired a small job left by another company.
