great service

they upgraded the insulation on my attic. the technicians were friendly and courteous. they took care in assuring that all the floor was covered and they even put a plastic cover over my bed (the attic entrance is in the main bedroom).
Based on the service that i received, I would recommend them.

Home Attic Insulation

Best Company for the job!
GNI was in constant communication with me from the moment the sales rep came and told me the situation and estimate... to the day of installation. Price was fair for the work that had to be done plus the recommendations of work that SHOULD be done. On the day of Install...the 2 workers that came over were very informative, clean and time efficient. I was very happy with the end result.

Insulation Installation

Tom and Brian from the Barrie Branch were pleasant and polite. When they first arrived they took great care to make sure that everything was set up before blowing in the insulation, in such away to minimize any disruption and mess. After they finished they left the work area clean and tidy.

Spraying of insulation in attic

I received great service from the time I placed my call to have my attic sprayed. Glenn followed up with me after he came to have a look at my attic and provide me with a quote. I then received a call to set up the appointment and the day of the spraying Derek and Drew were prompt and were professional. I appreciated the fact that the hose could fit through the bedroom window versus having my front door open for the couple of hours that they were there. Cleanup could have been a bit better, but I didn't mind doing a more thorough job.
