First of all, I would like to say that I am a builder and have used many building supply stores across the GTA. I saw the great prices of GBM and gave them a call for my upcoming job in richmondhill.
Not only did I receive a great price, but the quality of service offered by the guys was exceptional. From ordering the materials, to having their crew carry the drywalls and insulation to the specified rooms and floors.
If you are looking for your ultimate building store, do not hesitate to give these guys a call. Ask to talk to Rob or Kel, and they will give you the best prices, and beat any other competitors price.
