I had Great Canadian replace the siding ,install Foam Board insulation and Smart Board and parging to our house 2 years ago. The house is only 13 years old. They did a fantastic job, very professional and there quote for the job was reasonable. In 2017 i had them replace the 2 oustide doors, inspect the attic and add more insulation to it. The original Builder did not do there job properly. Great Canadian did there job properly. Doors no longer let air in underneath the bottom seal.
I did recommended this company to a friend of mine and he had them redo his roof. No complaints.
I would most definintly use this company in the future. I asked them to look at my furance. They recommended someone to me and they came and looked at my furance. The individual come and made some recommendations to do and furance works better then before.
Inj my opinion this is a solid Company.
