We're Committed to Excellent Service

I’ve been working with Promain for about 5 years now; they cover most of Ontario for me. We have a great working relationship, their pricing is competitive, and they quickly react to service calls. They are sensitive to keeping disruptions to a minimum for our guests which has been crucial to our business.


Promain has been heavily involved in asphalt, concrete, and interlock stone work over the past several years at Panasonic Canada’s Head Office in Mississauga. With each experience, we have been thoroughly impressed from proposal submission to their attention to detail, work ethic, professionalism, superior customer service and completing jobs on schedule.


From small potholes and large sinkholes, to crumbling brick, to walls smashed by trucks, Promain has been able to handle all of these situations effectively and promptly. When I call with a problem, I know it will be addressed promptly, and managed in a timely manner.
Anthony has taken this company from an asphalt paving service to a superior exterior maintenance service.
