The blower door test value decreased 100% after the very first day, after John's crew sealed the floors of our large attics, and sealed a small channel under the slab that allowed cold winter air to chill tile floors throughout the kitchen/DR. A very drafty house was converted to a far more comfortable house. The final number was about 30% of the initial value. A rather inefficient hybrid whole house fan/attic fan was converted to an efficient and weather-proof whole house exhaust fan for summer use. While we will not know how effective the insulation and all the other improvements will protect us from extreme heat and cold, from everything we have seen, we are (almost) looking forward to another cold winter to test the insulation. John is the boss, not a salesperson. I had interviewed several other building scientists and insulation experts and had no trouble choosing John. He knows his business, he knows how to explain what he wants to do and why, and he worked with me, not against me, to complete the job. He made two proposals, and we ended up with a hybrid work scope. Very professional, organized, hard-working. They checked the blower door data after every major portion of the work, and exceeded their targeted reduction in CFM 50 by approximately 2-fold. They had to adjust a few recessed lights that were a little askew after sealing and insulating a small attic, and they came in part of an extra day and fixed everything to my satisfaction. I was looking for a local building science specialist to examine my very large, leaky and complex house, recommend and install ecologically sound insulation. John was not the cheapest, but he noticed a number of things about the house that others missed, and he was clearly very capable and very willing to explain my options in great detail. I had a lot of confidence in his company, and I am very pleased with the results.

From John's initial consultation I got the impression that not only was he knowledgeable, but he enjoyed the process of making people's home's more efficient. He was professional, personable and easy to work with. The crew worked expediently and they seemed committed to a high level of craft. I am a carpenter myself, so I was certainly checking out the work that they had done at the close of each day and I was never disappointed. I was impressed with all aspects of each stage: cellulose blown insulation into the wall cavities, 2" foam board installation in crawlspace, vapor barrier installation under kitchen crawlspace, spray foaming around the sills, and installation of double paned windows in basement. These guys are a professional outfit with a reasonable overall price. Jill was great at helping us navigate the NYSERDA loan process and was always friendly and easy to deal with. Thanks again!!
