Great job of upgrading attic insulation to R60. Easy and fast quote process, competitive pricing and quick turnaround. Tom, Brian and Derrick from the Barrie branch were professional, friendly, tidy and efficient. Highly recommended.

Just had my attic installation upgraded By Great northern Installation the technicians - came on time very professional an approachable with any questions, walked me through what they were doing - IN and Out completed clean up and out in less than 2 hrs excellent Job Thanks Brian and Tom from the Barrie Branch

GNI informed us of the government grants for insulation so we signed up to bring our attic up to modern code. A job well done and pleased with the work

Derek and Andrew arrived on time. Both were polite and answered all my questions. They covered up the area with plastic sheets and used carboard to protect the walls. They also took their boots off when entering the house and vacumed any loose insulation. Highly recommended. Claudio

I had two estimated for attic insulation under the government greenon.ca program. Great Northern was by and far the most reasonable. Everyone i dealt with from the salesperson to the receptionist and finally the installers were extremely friendly and knowledgeable. After the $1,200 government rebate I paid $156.00 to have a 1200 square foot attic increased from r35 to r60. I am sure I will more than make that up in the first year. Thanks again Great Northern Rick - Craighurst Ont.

Tom , Brian and Malcolm showed up on time , were neat and tidy , and courteous while they scrambled through my attic , doing a nasty , difficult job well I have no reservations in recommending this firm to look after your insulation needs . Alex .

Richard visited our home to do an assessment, and to setup a date for installation. Derek and Nick arrived on time, completed the job cleanly and efficiently. After the task was done they cleaned and vacuumed any debris that were left behind. All individuals involved were very professional and pleasant to deal with Highly recommend.

Very please with service from start to finish. The crew was on time, very clean and informative. Would highly recommend this company to family and friends. Glad that I used this company for our attic insulation.

What a stress free upgrade! From the start when Angelo came and gave us a quote and answered all of our questions. He even started the Energy rebate process for us. At first there was a small hiccup with one of their machines but they quickly returned and didi a stellar job. Derek / John / Andrew ensured that their work was non intrusive and cleaned up all areas they worked in. I was so impressed with the product / everyones work I recommended it to 2 of my neighbours and them to other neighbours. Well done everyone !!

Great northern insulation is an excellent company. Starting with the office staff, to sales and finally the installation crew were very professional. Top notch! I would highly recommend this company!
