Went great! The owner and his workers are fantastic and they do great quality work! We felt an immediate difference in the upstairs room temperatures inside our house after the job was completed. The baby room, office and guest bedrooms that were all previously that hot in the summer compared to the rest of the upstairs improved dramatically. The job was very well-done, they clean up well and are ...

I received Green Stone Energy’s name after having a very thorough and professional energy audit completed by PECO as part of their efficiency program. I met with Dutch from Green Stone and we walked through his suggestions and planned approach which seemed reasonable to me. As promised I received an estimate within a couple days of the visit to my home outlining the project and was what we discuss...

We had an initial call with Green Stone (GS) and agreed to get an estimate. We did the same with several other contractors. The GS representative "Dutch" came to our home and was very knowledgeable of the PECO results and provided a detailed list of energy saving measures we could possibly pursue. The list was broken down into three specific areas based on PECO's report. Each section had an indivi...

Initial request for pricing was done in a very timely manner by Butch. Took him ~30 minutes to do a thorough assessment (compared to other guys who took 1-2 hours to do the same). Estimate was reasonable and price-wise comparable. I did not feel like he was nickel-and-diming me. They were reasonable to accommodate within 2 weeks. Showed up on the agreed upon date and time to start. Very profession...

They arrived in the time frame indicated and started work immediately. The work team was very courteous and cleaned up the area before leaving. They asked me to inspect their work, and I was very pleased. Their pricing was reasonable for the job - plus they were much more responsive than other companies I contacted. I highly recommend them.
