The staff talked me out of a higher end product as he felt it was too nice for the application I was using it for (rental property). It was less money for him but he was more concerned with finding me the right product that met my needs. 10/10

We purchased material recently from Alpha Building Supply for the renovation of our showroom and we are pleased to learn there are still businesses out there that still uphold traditional customer service and values. The staff was informative, helpful and courteous from start to finish. Was a pleasure. Highly recommend!
