Couple years ago in 2013 I bought a house. The main floor hardwood had some scratches from a dog and I wanted to get rid of the carpet on the 2nd floor and get hardwood there. Looked around and finally settled on "Image Floor Coverings" in Scarborough. (http://www.imagefloor.ca). The owner "Jay" came to my house and sounded really knowledgeable and said that he can varnish the main floor and 60% of the scratches would be gone. So he varnished the main floor and installed hardwood on the 2nd floor. The guys he sent to work looked immigrants who couldn't even speak/understand english. That aside, after the varnish I had bubbles everywhere all across the main floor. I showed it to him and his guys applied another coat, same bubbles again. So finally after much back and forth and the fact I held the last portion of the payment he agreed to sand the hardwood and varnish again. This time I still had bubbles but they were liveable and because I was sick of all the mess I decided enough is enough and lived with the outcome.
After a year the varnish started to peal, another professional said its a cheap varnish and not thick enough to cover the joints between the wood planks. Also my hardwood upstairs started to get cupping that started from the middle of the house and then all across even though I kept humidity controlled up to 40%-60% all year round and kept running dehumidifiers in the summer. Callled Jay again for cupping issue on the 2nd floor and he wouldn't reply, kept calling for months and nothing, even though they say if you install our product through us they give 25 years warranty. Finally decided to post this so that others don't ever use Image Floor Coverings.
