Ampac Paving is great when they are in sell mode. They are responsive, they show up on time etc but once they have your final payment, you will NEVER get these folks to return your call if you have a problem. My driveway heaved the first winter after Ampac Paving excavated and paved it. I have sent multiple emails to the email address on the Ampac Paving website advising of the problem – no response. I have left voicemails on the phone number listed on their website requesting a call back – no response. I even visited their “suite” at 9251 Yonge Street only to find that the suite listed on their website, business card and contracts as being 8565 does not exist. Ampac Paving gave me a one year written warranty. Unfortunately, that warranty isn’t worth the paper that it’s printed on. Ampac Paving knows how to hide real good!! Use them with extreme caution!
