As Covid-19 continues to affect our lives, we must do our parts. We care about your health and well-being and it’s the reason that we’ve decided to temporarily close our showrooms. Deliveries will still be scheduled and sent out to all fabricators (Except for our Ottawa location. Pickup only). For any inquiries please email info@interstone.ca or your Interstone representative. Thank-you for choosing Interstone Marble and Granite Ltd.
