We chose Alliance because of the excellent reviews on Homestars and were not disappointed. Timea helped us pick a high quality vinyl plank flooring product and was always responsive to our questions and concerns--in person and on the phone.
After purchasing the flooring (which we intended to install ourselves), we discovered an issue with the plywood subfloor. It was very uneven. Our general contractor made it much worse by incorrectly applying concrete self-levelling compound and leaving us with a concrete mound in the centre of our living space! We were distraught.
I got in touch with Alliance again. Lehel paid us a visit and, after assessing the floor, sent someone to fix the problem. He removed all of the concrete (quickly and with little mess) and sanded the plywood subfloor until it was much closer to being flat. Given that we were unable to get it perfectly flat, and that this would mean a more challenging installation, we decided to hire installers recommended by Lehel. They did a fantastic job. Their cuts were incredibly precise, including around our kitchen island which was installed prior to the floor (see pics). And all of the work (subfloor prep + install) was done at a very reasonable price.
We'd highly recommend Alliance, especially because of the fantastic service all around. They are honest, straightforward and very knowledgeable about flooring. They made a stressful situation much easier for us.
