Green Stone Energy LLC

Excellent Weatherization Service - Highly Recommend! I recently had Green Stone Energy complete extensive weatherization work on my home, including attic insulation (R-60), air sealing, duct sealing, and insulation for the room over my garage. I couldn't be happier with the entire experience. Erick was fantastic from the start - he provided a detailed, thorough estimate that clearly explained every aspect of the work and was incredibly responsive whenever I had questions. His professionalism and communication made the whole process smooth and stress-free. Roman and his crew were equally impressive. They arrived right on time and worked incredibly hard throughout the day, completing all the work in a single day despite the scope of the project. Everyone on the team was friendly, professional, and clearly took pride in their work. The attention to detail was evident in everything they did - from the blower door testing to the careful installation of baffles, air sealing, and the blown-in cellulose insulation. They also helped me take advantage of PECO incentives, which made the project even more affordable. If you're looking for a reliable, hardworking team to improve your home's energy efficiency, I highly recommend Green Stone Energy. They delivered excellent service from start to finish!

I had weatherization done a few days ago, just as a very cold snap moved into the area. What a difference!!! I could feel warmth in areas that never were quite warm before. In the past, my heater could not keep up with very coldest of temperatures but now my thermostat is holding steady. GSE, LLC even took care of the paperwork for rebates associated with my weatherization. So efficient! So worth it! Roman and his crew were highly professional, knew their "craft" and did it well and within the expected timeframe. They respected my home and cleaned up afterward. Even warned me about the particles that may be floating in the attic air for a few days until it all settled down. Excellent service! Excellent price! Highly recommended! Absolutely the best!

Erick communicated well, explained the work clearly, and provided detailed, itemized lists of what he proposed and what each thing would cost. We put the project on hold for more than a year while some other things worked out and he was able to pick right back up where he left off. Greenstone took care of researching the power company incentives and did all the filing - I only needed to sign a single form. That was great. When the appointment was scheduled we got a heads-up who was coming, the crew came on time, they were willing to explain the steps they were going to go through, and they took good care of our place while they were here. The attic ceiling access is in a carpeted closet and it lookied like they were prepared to make it a biohazard clean room with all the plastic sheeting and temporary wall supports they put up to contain the dust etc. They cleaned up so well I didn't even need to vaccuum that carpet. The workers were friendly, and on the post-install walkaround I requested that they seal off a couple of the access panels with caulking because we don't use them often and they are too flimsy to properly fit weather stripping. The crew chief pulled the team back in to take care of it right away even though they had been waiting for 20 or so minutes for my meeting to end. The price was a little more than we were hoping to pay, but it was similar to the other two quotes we got. The service exceeded my expectations and so far the results have been good. we were the only ones with frost on our roof this morning in the neighborhood.
