• We're thrilled about the fact that what seemed like a breezy cardboard box is now a cozy home. What a huge difference we're feeling around here. I think your team did a great job, and I'm especially happy about what a great job they did of cleaning up after themselves. There was practically no sign that any work was being done around here. Aside from the wonderful results.

  • It's the "personal touch" that makes working with ECS on a project fun and rewarding. Bill and Melinda have a sincere passion for their work, and are committed to good environmental stewardship. Each project is custom-designed with that in mind. We never had that "one size fits all" feeling that some contractors project. Work was done in a timely fashion, and coordinated with the contractor who did our HVAC job. Ours is a mid-century ranch house - built when energy was cheap! ECS helped make our house energy efficient for the 21st century. We have already saved over $800 the first winter on our heating costs, and the comfort of our home now, compared with before, is night and day.

  • Bill is one of the most thorough, diligent and pleasant contractors I have ever worked with. He has incredible patience in explaining every and all details. He also has a vast amount of knowledge and is a great resource for all things related to energy efficient building. I recommend him whole heartedly!
    - Joanne L., Rhinebeck, NY

  • Bill is knowledgeable and thorough, and he really took the time to explain what he was doing and what he found. He also asked questions to get a sense of how handy I am, and tailored his report to show the changes I could make myself without having to hire a pro. He's one of the best. I recommend him wholeheartedly.

  • The insulation resulted in a much warmer house for less fuel. I'm comfortable and very pleased
    - Jim G., West Hurley, NY

  • We had to leave our house due to my wife's and my chemical sensitivity. Bill was able to diagnose the problem and found the source of mold in our attics. His report was complete and very informative. His team removed the damaged insulation, and when he was done properly air sealing, installing proper ventilation, and insulating our house we were able to move back in and the house is wonderfully warm. We are very happy and highly recommend Bill and his team.
    - Roland P., Olivebridge, NY

  • I was impressed by Bill's vast building science knowledge and how he took the time to explain it all to me. I had him insulate and air seal my turn of the century house and now I am safe, comfortable, and am saving hundreds of dollars a month on my fuel and electric bills. I highly recommend Bill McKnight.
