    Ahmad was the quickest to give me a quote, works with a BayREN inspector to get rebates, so I wound up selecting his company because after rebates it would be the cheapest. I had an install date for about 3 weeks away, returned from vacation a day early to move everything away from the walls by 3 ft on a Sunday for a Tuesday appointment. Got a call that Monday that his crew was out with COVID (totally understandable, since I myself and many coworkers had been out with COVID about that time). Rescheduled for 8 days later (2 of those days were because of my schedule). His crew arrived on time and were very friendly and helpful reexplaining the process (since it had been over a month since I got the quote). They were fast and efficient. Sadly, once they had a check in hand Ahmad was terrible about returning texts. I had three simple questions (rebate inspection, dry time for spackle, why a quarter of one wall didn't get insulated), took a day or more but he returned an answer to one of the questions, asked a clarifying question about one and ignored the other question. No response to my response to the clarifying question. When I was going through with the BayREN inspector I found that the installation crew completely annihilated a light fixture in the closet of the attic access. I didn't even bother to try to get a hold of them to get it replaced since I would waste more time getting no response than I would heading to a home improvement store to buy and install a replacement. Come to think about it I probably should only rate a 4 star because I'm worried about damage I haven't found yet, and also annoyed at how little of my exterior walls wound up with insulation, but I don't want to lose all this typing.

    Thank you for your business.

    This is an awesome company to do business with. They are honest, reliable, and do an outstanding job. My insulation was very old and my upstairs had become unlivable because it was so hot. I sought out 3 bids and I decided to use this company because of the outstanding experience I had in working with them. The person who took my call was very helpful, courteous and warm. They came out right away to inspect and give an estimate. They did not try to upsell and I felt very comfortable in what they said I needed. The installers arrived on time, got the job done, were super conscientious and efficient. I cannot say enough about what a great company this is. My house feels so much better. Do not hesitate to contact them if you need insulation and you will not be sorry.

    Response from Company:

    Thank you very much for working with us and we appreciate your business.

    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.
