How Fast We Get to You in Ajax
Ajax is reached off Highway 401 and Highway 407 via Salem, Harwood, and Westney Road. Two hours is our emergency target, and 401 congestion east of Scarborough is the main variable in the late afternoon. Gas emergencies are covered 24/7.
The Homes We Work On in Ajax
South Ajax holds older wartime-era housing with aging equipment and original venting. North of the 401, the subdivisions are largely post-2000 and are now due for first-generation equipment replacement. Both patterns show up in our week, and each calls for a different starting assessment.
