Attic insulation by GNI

Contacted GNI after I saw the reviews on Home-stars.
Communication started not as smooth as I wish.
Late is the key word, late response, late arrival of sales person, late receiving the quote and insulation guys were late as well.
Now comes the flip, Jordan managed to reschedule the work to Sunday brought Will with him and both of them worked and finished the job.

To management I would recommend to review your operation process for that alone I would give 4/10.
For the personal you get 10/10 especially for guys like Jordan and Will.
These kind of guys are the ones you want to make sure you keep in your company.

Removal of basement fiberglass insulation

Phil and Bill did a great job of removing and disposing of the fiberglass insulation in our basement. They answered all of my questions in detail. Very respectful and courteous. Great team work!

insulation

Dan and Chris showed up on time and covered entrance way and stairs with plastic. The job was performed very quickly with very little mess. I would highly recommend them.

Bathroom renovation

Talk about an efficient Company,
They were extremely quick in having the job done in the time set up and made sure the communication was clear and easily understood from the start. The crew who came to our house were courteous, friendly and very knowledgeable. They protected our belongings and made sure the job was expertly completed and cleaned up thoroughly.
Great job from start to finish !!
Thank you,

Attics - House and Garage & Walls - Garage

Being made aware that the installation would produce dust in the house as well as in the garage, I made preparations ahead of the work. I erected a dust partition to save myself a lot of additional vacuuming in my living/dining/kitchen area. Bedroom doors were kept closed. Minimal cleanup was required by doing that. In the garage, I covered the built-in shelving with plastic sheeting again which saved significant clean-up. The insulation work performed immediately reduced the air-conditioning required for the house. The garage is also much cooler than normal now the it is insulated. I'm very satisfied with the outcome.

Attic Insulation

We couldn’t say enough good about the quality of service GNI provides. Angelo, Drew and Tom were all very professional, friendly and efficient. We would highly recommend GNI to anyone looking for insulation.

Worst company I have ever dealt with

GNI visited my home 3 times this month, and there were problems all 3 times. Beyond frustrating and disappointing...

1) While removing existing blown-in fiberglass insulation, GNI vacuum hose tore from the waste bag in the disposal bin (they do not use self contained trucks - you have to pay for a rental disposal bin). The result? 1960s attic insulation falling from the sky like snow all around my property and that of my neighbour's.

Clean-up was not complete and not satisfactory. I had to clean up after GNI left.

2) While blowing in R60 cellulose, GNI badly damaged (completely tore off) an attic air conditioning hose that was fully sealed and screwed into the vent which vents into our family room, resulting in the R60 cellulose flowing into our family room. They also totally buried the air handler in insulation, despite being asked to stay clear of the air handler and not get any insulation on it at all.

3) When GNI returned to clear a pathway from the attic air handler to the damaged vent / hose so that the HVAC crew could repair the GNI damage, GNI only completed half of the required work they were hired to do; they only cleared 10 out of the 20 necessary ft.

HVAC crew arrived to repair the GNI damage but were unable to complete the repair, for a second time, because of GNI.

It has also been very difficult to get a hold of GNI office workers for scheduling, etc. Phones often not answered and voicemails often not returned.

We are completing extensive home renovations and have been working with numerous companies (electrical, hvac, general contractor, plumbing, etc) and everyone has been great, except GNI, I am truly disappointed and beyond frustrated with the customer service when trying to address these grievances.

If you go with GNI, I hope you have a better experience.

GNI office staff have refused to provide me with phone numbers or emails of Managers so I am writing this review in hopes that someone at GNI will see it and become aware of these issues so that as a company, they can make the necessary improvements and prevent future headaches and frustration for their clients.

insulate attic

Initial contact from representative was made through email. Everything was straight forward about receiving a quote and set up for payment and the installation date. The guys arrived on time and they presented themselves as polite and professional. They laid down drop cloths to protect the floors. they vacuumed up their workspace before they left. I definitely would refer this company.
