Review by in Troy, NY
Todd, the owner, was not able to work on our project the first week, but Greg and Zach worked very hard. They insulated every part of the house including the "ceiling" and walls of 2 crawl spaces, the walls, the attic and used spray foam to seal the rim. This was a big job and it took longer than was anticipated, mainly because of the extremely tight area of one of the crawl spaces. It was so small that another company told us they wouldn't be able to get in to do the work. Todd's was not the lowest quoted price, but he was planning to do a lot more than his competitors and we figured we were going to do this just one in our lifetimes, so we may as well do it right. They did not rush through it to save time. It took longer, but it was done right. One reassuring thing was that before and after photos were taken. This was really important to me since I could not get into the places where work was being done and it would have been easy for a contractor to say, for example, that insulation had been blown into the walls, but I would never really know unless I was there actually watching because the siding is put back up and it doesn't look any different than before. Very honest. I appreciated Todd's communication in a timely and thorough manner. At times this was via email and other times he called me to answer questions. This was a large, expensive project and we do not yet know what the resulting cost savings and comfort level will be in the house going forward, but I believe that every possible detail was taken care of to help us achieve better comfort and efficiency with the house. I will not hesitate to recommend Todd and his crew to my friends and family if they need this type of work done.

Project: Install or Upgrade Insulation
Both professional and results. Simple but example of professionalism, answered phone when I had questions even texted said running late when needed to be kept you updated on project. Example of results, used 140 gals less of propane over winter saving over $400.

Review by in Rexford, NY
Project: Install or Upgrade Blown-In Insulation
Very professional veteran-owned business. These guys worked methodically and took their time. They used a FLIR to find air passages, foamed them closed, and then blew in the cellulose. They took pictures (before and after) of the trouble spots and showed them to me when complete. Cost was exactly what they estimated/quoted. Very happy with the results. Strongly recommend.

Very professional with quality workmanship even when faced with unforeseen challenges at the work site.This was the first time EVER that I was able to leave the door open to this addition for the entire night without a cold draft blowing through the house. Very pleased.

Review by in Albany, NY
Todd and Greg were great. They were extremely through and honest about what energy improvements I could do myself and what might be worth getting a professional. They explained everything well and in simple terms. Todd was easy to contact and kept us updated on the progress of the report. Would definitely recommend for anyone looking for an energy audit!

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
