Ashley R. – Sacramento, CA
“Cornerstone saved me over $2,300 when my air conditioning unit stopped working during a heatwave. The tech was at my home within 24 hours, and I only paid the service fee. I’ve already recommended them to my neighbors!”
Tanya B. – Orlando, FL
“I was skeptical at first, but I’m seriously impressed. My fridge and washing machine were both covered and replaced quickly. The customer support team was super helpful and walked me through the entire claim.”
Mark D. – Austin, TX
“I bought the bundled plan for my house and car, and it’s been worth every penny. My transmission needed repairs last month, and Cornerstone handled everything from towing to the shop. No hassle. Just peace of mind.”
