Cornerstone Advertising is a US marketing and advertising agency that works only with home service contractors. It positions itself as a client's outsourced marketing department, planning and running digital and traditional campaigns under one strategy, and it has served this trade for more than 30 years.
Its clients are residential contractors in HVAC, plumbing, electrical, roofing and home remodelling, at every stage of growth and across the country. The agency takes on only one competing contractor per service area, so each client has an exclusive territory, and engagements run without long-term contracts.
