I have two good things to say about Granite Prestige: a) their installers are very good; and b)…read moreRon, the sales manager, knows his business and means well. That said, consider the following: a) we initially got a quote from them that was lower by about $3,000 (for quartzite countertops and backsplash) than 2 other quotes. When I looked into it, I was shown a plan for how 2 slabs would be cut up that would make all the pieces fit. So I thought they were just cleverer than the two other firms who were going to use 3 slabs. It turned out - I found this out much later, after the countertops were installed - that they miscalculated. We really did need a 3rd slab. Luckily, it was possible to find one from the same lot of 50 - the very last one; b) Jose Fabre, the production manager, does not like to thin quartzite. It takes too long. And he refused to thin it all the way to 3/4 inch as originally agreed. (It is true that quartzite is harder than granite. Some companies refuse to thin it.) Our job was put at the back of the priority list so the first attempt to install the backsplash occurred more than 3 months after the countertops were installed. We were strung along for months waiting for this to be done; c) I wrote "the first attempt" - because when the installers arrived, one of the backsplash pieces incorrectly had a hole for a double outlet cut, so we had to get our contractor to come back and move the one outlet before that piece could be installed; another piece was not cut properly and needed further trimming before it could fit; and a third piece, for our bay window, was cut too big; d) the company does a very poor job of communicating with its customers. Ron does not control Jose's work and cannot speak for Jose's plans, and Jose returns calls when he finds the time. At one point I felt I had no choice except to drive to their shop to find out what was happening, because Ron was on vacation and not answering his emails, and Jose was too busy to return my repeated calls, even after 3 days. In the end, the installers were able to come back, 4 months less 4 days after the countertops were installed, and the installation is very good. That's why I gave the company 2 stars instead of 1. I am sure all these negative experiences will fade into the background over time, the installation looks very good, but as of this writing (November 2025), Granite Prestige is not a company I would recommend.

In july 2022 i was looking for a contractor to renovate my kitchen and i found KSI. They told me…read morethat i have to give them a deposit to come measure and make the design in spite that their design is "free". At the beginning they promised me that they can make my kitchen at certain date then they changed the date. Anyway ate the end I found another contractor. Then i asked KSI to return my money because the only thing they did is the design which is free which they refused. In spite that based on our contract that they keep the deposit which i can use for another project this is absolutely illegal in Quebec. So this year july 2025 I had to renovate my bathroom and i saw on their site that they do vanity so i contact Teresa and decide to order my medicine cabinet, bathroom vanity, a sink, a faucet, handles at KSI. I new that the installation is not included but because i thought that the assembling is included i paid for the deliver. And the date I have to receive them was July 9th. This is what i get like a service: -the deliver was done 4 weeks later -the handles and the faucet are missing -the medicine cabinet (pharmacy) is actually with the size of a kitchen cabinet, -the cabinets were not assembled -the vanity has a problem with one door that cannot be aligned. After i contact them, I got nothing but just extra screaming on the phone which is actually their ways of helping me. Teresa tried to convince me that none of these is their fault. So I would advice you to stay away from this company if you can
