It is rare that you find a company these days committed to the needs and requirements of a customer. The management team and employees of AM Group although indeed say what they do, and then do what they say when it comes to meeting and exceeding the expectations of a customer. In the case of my wife and I, they laid out all of the options available for our needs, took the time to explain the products, installation process, and offered competitive pricing with what we believe included the best warranty in the business. Their installers of the product were cordial, professional, and left our property in better condition than when they first arrived. Truly a rare customer experience in this day and age

Michael and Paula Chabot, Collingwood

The guys did a great job, very neat and professional. Have had several positive comments already from neighbours. They noticed the difference from other roofs that were done on my street by other roofers, ours looks a lot better. I certainly will be recommending AM Group of Companies.

Jayson Fosbury,

Thank you to everyone at AM Group. This as a hassle-free experience…you did exactly what you said you would do! The roofing crew did a fantastic job. They worked quickly, professionally and neatly, leaving the grounds as they found them. I am very satisfied with my roof and I’m so glad that I decided to have AM Group replace it.

Fiona Phillips,

To Mike & everyone at AM, Excellent job. The job performed was very professional with a large crew, finished a day early which was appreciated as the roof was in dire need of being replaced. The guys worked hard and I don’t think they ever took a break! The roof looks great and no surprises in the final price, which was the same as the quote. Best of luck in the future! I will certainly recommend your company.

Al Claeys, Owner of Stampede Ranch in Guelph

We were thrilled with the windows we had put in. The crew were great. Very professional, worked with my schedule, showed pride in their workmanship and cleaned up very well when done. We would call them again for any work we needed with no hesitation.

Dan & Kathy, London

We did a complete renovation on our house down to the brick walls. All new windows, doors, and insulation. AM Group was very helpful in get me over $10,000 back in rebates. There were very easy to work with. 

Clair & Justin G., Waterloo

Work was done in a very professional and timely manner. The rep thoroughly explained the process and I understood what had to be done and when. I am exteremly happy with the fact that I havent had to deal with any paperwork - they covered the auditor, filed everything and installed top notch windows. I am pleased with the process. I would recommend this company to anyone interested.

Sean Cristoff, Barrie

They were friendly, clean and quick. Walked me through the rebates offered, and I got back every cent I paid. Very easy to work with. I had my attic insulated and they kept me informed on what they were doing.
