Best place in the game for drywall and doors. These guys are a special bunch, from the friendly staff at the front, to the solid ones out back.
I only use CDS for any of my drywall supply needs because they are simply unbeatable!
Found this place as a distributor for trim tex product- curved corner bead. We used this for our curved wall project and everything turned out great. Richard and Ron were fabulous work with great prompt service and availability of product. They even helped me bought some of the stuff out of my car, which was much appreciated it.
I had a fantastic experience with CDS Drywall Supply Company. Their professionalism and expertise truly set them apart. From start to finish, they provided top-notch service, I highly recommend them for all your drywall needs.
The guys at CDS are amazing. No matter what your building needs, the knowledgeable staff can help you out. Would recommend them for any job big or small. Thank you for your efforts. You have my respect and appreciation
I'm an industrial supply customer.
Gene and Justin have always taken care of my needs. As of late with a project downtown. No sooner than I send them a PO, it seems to be on site. Quotes fast and deliver fast. It's no shock why they are a Markham institution.
