    In 2019-05-03 Great Northern Insulation blow in cellulose insulation into our attic and into flat attic space of garage to achieve R 50. We were quite happy with the process until 2 yrs or so later when we realized that we were unable to keep up with the dust we had coming into our house through the light fixtures and light sockets,and overhang and windows and doors( we didn't realize that was the problem at that time) We called them back numerous times when we realized where the dust was coming from and they would go into the attic and attempt to fix the problems, which never happened. In Feb of 2022, they told us that's all they can do for us and as they were leaving town and no longer do residential. So they left us to fen for ourselves. Since then we have hired ppl to remove the cellulose but the dust remain and we are stuck in our house with no insulation and we cant find anyone to put in batts. We are feeling abandon by them at this point. We have spent thousand of dollars now and have not resolved the problem they left us with. We paid them $1,806.87, and have paid 3 times that trying to fix this issue ourselves.

    I thought I had made a good choice in moving ahead with GNI for a hybrid attic installation on my home.  Nope--it turned out to be the worst experience I've personally had from any contractor that has worked on my home over the last 13 years of home ownership.  Below is my honest account of some (not all) of the low-lights of this experience.   1.) the install was scheduled to take only 3 days to complete but ultimately spanned over approximately 11 calendar days, causing significant and unnecessary disruption to my family 2.) disorganization and poor internal communication led to incorrect foam type being installed in the corners of my attic. I had to spend considerable effort to advocate for this to be addressed and resolved.  GNI needed to return to remediate to prevent possible future mold issues. 3.) GNI labourers needed to borrow basic tools from me because they either didn't have them, or theirs were broken. 4.) there was poor preparation work done to properly protect my refinished hardwood flooring. Had to purchase and setup my own flooring protection This relatively simple installation was an awful experience from the very start and right through until the very end.  GNI acknowledged these issues by offering a discount of approximately 7.7% in an attempt to make up for the experience and to cover the additional materials I needed to purchase.  While the items in the scope of work were eventually delivered, I feel this discount is not sufficient given the amount of unexpected disruption and chaos that my family needlessly experienced.

    Hi ****. Providing reliable and professional service is important to us so we thank you for your review. This gives us an opportunity to provide our teams with customer feedback and help improve our processes. Unfortunately, the scheduling delays you mentioned did result from a change in the scope of work mid-project. This ultimately meant reconfiguring your project to meet the new requirements. We can appreciate that living in a home with ongoing renovations is a challenge and we do apologize again for the home disruption you experienced.

    We appreciate you choosing Great Northern Insulation and are pleased that our crews were able to complete the work as scoped. We're confident that you made your home more energy efficient and will experience the positive effects for years to come.

    UPDATE: please know that I did not change the scope of work for this project. The scope of work was very straight forward, and included the following items:

    1. removal of existing insulation
    2. installation of rafter air baffles and fiberglass batts for soffit area
    3. installation of approximately 2" of spray foam for air sealing
    4. installation of blown-in cellulose insulation
    This was for an approximately 900sqft attic space aiming to achieve R60+

    The "change of scope" GNI is referring to in their reply may be related to the issue that was caused when GNI installed the incorrect foam type in the corners of my attic. This seems to have been due to major disorganization and poor internal communication within GNI. I had to spend considerable effort to advocate for this to be addressed and resolved properly. GNI eventually returned to remediate their error in order to try to prevent possible future mold issues.

    GNI's error caused considerable delay to the work being completed, and was extremely disruptive to my household.
