Great experience. 3rd time I have purchased at Cosmaroma Home Reno. Customer service excellent. Thank you to the gentleman who carried my flooring boxes to my car. I backed on ramp a bit short as my back up camera was fogged up. Very pleasant and no complaints. Will do business again!

Great, amicable service staff, very easy to get advice. Store wasn’t overcrowded and not overwhelmingly large.
Definitely a place we go back fir future needs.

We recently completed a full renovation on our kitchen and purchased our cabinets, flooring and quartz countertop through Tracie and Shania at the Kingston Cosmaroma store. We had a professional come in and do laser measurements of our kitchen and gave those measurements to Shania. Shania, Tracie and their team came up with a design that was absolutely fitting and beautiful. The quality and workmanship of our cabinets were second to none. The quartz top was a perfect fit and professionally completed. The whole kitchen was very reasonably priced and came in under our budget. Tracie gave us the name, Les Bentley Custom Carpentry out of Sydenham, Ont who installed our cabinets, crown moulding and flooring, professionally and most reasonable.
The whole experience was fantastic from the staff, the design, quality of cabinets, flooring and installation and the delivery and promises. Our kitchen looks awesome and we were most happy to work with Cosmarona and the people mentioned.
Kitchens are the focal point of any home and ours now looks beautiful.
Thank you all very much.

Had a really good experience buying my kitchen cabinets here. They are really great quality and very economical. We had to change the design a few times to make sure everything fit properly, but that process was pretty smooth. Delivery was reasonable and customer service has been great with the few little issues we encounteted. We also got some great flooring there and are going back for trim. All the staff are very friendly.

As a novice trying to lay down vinyl floor for the first time, i was able to get the best guidance by the experts here and also the best options for the flooring
Jason ,in particular, was very helpful and patient with my queries!
We ordered our doors for our basement. Took measurements. The lady that took measurements did not take into consideration other factors to have correct measurements. They took back doors and shipped it to Toronto to get adjusted. Received doors back and eventhough a worker came to see the measurements were incorrect, two doors came back incorrect. What was the point of having someone from the store to take correct measurements if the doors are still too big and he took wrong measurements as well. This is so upsetting. We wanted to keep it local and the service we were provided was very upsetting. People don’t care anymore. So basically spoke to regional manager nothing resolved except offering two blades for us to make changes. We refused. We just want the doors we ordered with the correct measurements given. I never write bad reviews but people should be put aware. This is not good customer service. We paid for something we did not receive. Customers are not always right I know but in this case unfortunately we are. We just want we paid for . Ordered 6 doors to measure. Horrible.

Lots of nice products.
Quite a bit more expensive than a friend who referred me to the store had said.
Return policy of only two weeks I find too short for the housing construction industry. Needs to more like one month in my opinion as I seldomly get contracted work completed in short turnaround times.
Thank you.

Great prices, great selection and helpful, courteous staff! We have purchased baseboard, casing, interior doors for our home renovation and have saved by shopping here. Staff are knowledgeable about the products and the building process, which is really helpful for us novices!
Over the past two weeks I have made several purchases. I was offered a vinyl floor product that had to be ordered but when I went to purchase it I was offered the same design at a lower price that was in stock. Pine trim and boards were cut to a size to fit in the car. A real pleasure to feel like a customer again. As a comparative shopper the prices are much better than the box stores. Congratulation Cosmaroma for your friendly helpful staff!
