Adviser extremely knowledgable, took time to explain everything, was willing to work within me in coming up with a plan and prioritizing work needed to save energy.
Adviser pointed out areas where there were drafts and problem areas I was unaware of.
Learned how sealing the basement windows and getting insulation into the corners of my attic space would make a bigger difference in the overall warmth of my upstairs.
Your customer service on the phone was great, such nice people too all around.
Honest and educational. Good explanation of what needed and was going to be done.
A great company with an amazing work ethic.
I am very satisfied overall. Seemed very knowledgeable. Was able to explain things in a simple way. Very friendly and easy to talk to. Felt comfortable asking many questions.
Is it possible to evaluate how beneficial, energy consumption wise, was the work done by your company?
Global Dwelling was very helpful and patient with every step of the NYSERDA application process. Every member of the team treated my home with respect; the pride in their own work was evident by the attention to detail and the way they communicated their progress.
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.
