What Contractors Say About Cornerstone
Contractors partner with Cornerstone Advertising for clear, structured marketing that drives measurable growth with accountability and alignment.
“The education part is what’s really important. When we ask questions, we get good answers and good explanations. So early on, that’s what made us so comfortable with working with Cornerstone.”
Alliance Heating & Air Conditioning
Kane D’Amico
“We were looking for a one-stop shop that, again, did everything. Most, if not all, of Cornerstone’s competitors were purely digital. And, you know, in this business, the service
industry, we needed a little more hands-on, touchy-feely, tactile stuff like that. And Cornerstone was really the only one that offered that too.”
Alliance Heating & Air Conditioning
Chuck Wilkerson
“Cornerstone was instrumental in expanding our residential services and equipment replacement business, springboarding our growth from $5 million to where we are today ($45 million).”

“We have thoroughly enjoyed our partnership with the Cornerstone team. The team has consistently demonstrated professionalism, attentiveness, and a strong commitment to our marketing goals. They have been responsive and proactive in supporting our initiatives, but highly adaptable to our evolving needs and timelines. We appreciate their ability to listen, understand our business, and tailor their support accordingly. Their flexibility, clear communication, and positive attitude make them a pleasure to work with. We sincerely value the continued partnership and look forward to growing together”

“I think when I hired Cornerstone, we were probably doing $5 million a year in revenue, and when I sold the company, we were doing $75 million. Cornerstone was able to bring to our organization marketing strategies, tactics and execution that aligned with and supported our growth plan. Cornerstone helped get us to where we wanted to be.”

“Working with Cornerstone has been a game-changer for our marketing department. They’ve taken tedious, time-consuming tasks off my plate, allowing me to focus on bigger-picture strategies. More importantly, their team brought fresh insight and structure to our campaigns and platforms, strengthening our overall marketing presence. They truly listen to our needs and consistently follow through with thoughtful, actionable plans. It’s clear they’re invested in our success, and their responsiveness and strategic support have made them a valuable extension of our team. Highly recommend!”

“For me, there are two key benefits of working with Cornerstone. First, I am able to turn over all my marketing and advertising to Tracy and his team so that I can focus on our operations.
Secondly, with many years of experience with many HVAC contractors throughout the US, Cornerstone brings us a toolkit of best practices providing us with a proven pathway to growth.”

“While Tracy and his team were spot on with strategy and tactics, knowing it to be an important aspect of your marketing… what I appreciated most while working with Cornerstone was their creative and design of our brand and marketing materials.”

“After years of working with different agencies and never quite finding the right fit, partnering with Cornerstone has been a game-changer. Your personal touch and genuine investment in my success make all the difference. I used to feel overwhelmed every time I had to think about marketing, but Cornerstone took that burden off my shoulders so I can stay focused on my business.”
