Cornerstone Advertising

Based in Westfield, Indiana, Cornerstone Advertising works specifically with home service contractors — HVAC, plumbing, electrical, roofing and similar trades. The agency has operated for more than 30 years, positioning itself as an outsourced marketing department for its clients rather than a vendor delivering isolated projects. It offers exclusive territory protection, working with only one contractor per service area, and operates on a month-to-month basis without long-term contracts. The agency's stated expertise spans both digital and traditional marketing channels, organized around five areas: digital lead generation and visibility, website strategy and infrastructure, media and advertising, retention and database marketing, and brand and creative direction. Concrete services listed include search engine optimization, OTT and CTV advertising, web hosting, design and management, traditional print advertising, social media marketing, email and SMS marketing, LSA and PPC management, reputation management, and branding and creative services. Cornerstone describes its approach as bringing structure to marketing by aligning strategy, budget, and execution, with the stated aim of giving contractors visibility into where revenue originates, which channels warrant further investment, and which should be reduced. The agency states it works with residential contractors at various stages of growth, tailoring plans according to each client's current position and goals, and emphasizes accountability and measurable performance tracking as part of its ongoing client management.
