Tulsa's Cornerstone Chimneys

Trusted Experts in Fireplace Safety

The Randalls didn’t just take over a business—they reignited a passion for safety and community when they purchased Cornerstone Chimneys in Tulsa. Firefighter founded, the importance of fire safety is rooted in their business, making Cornerstone Chimneys a trusted name in Tulsa and surrounding Green Country. “Fire is inherently dangerous,” Kathy Randall explained, “and our goal is to help people enjoy their fireplaces without compromising safety.” It’s not just about cleaning chimneys or repairing bricks—it’s about creating a safe and inviting environment for families to gather around and make memories.

“The chimney industry has long been unregulated,” Kathy shared. The Randalls believe in educating their customers. “It’s an area most people aren’t familiar with, so we teach people why it’s important to have their chimney inspected, cleaned, and fixed when needed.” Cornerstone maintains certifications from CSIA (Chimney Safety Institute of America) and NFI (National Fireplace Institute). NFI certification is the only certification recognized by the state of Oklahoma and is required to perform the installation and repair of any gas-fired or fueled hearth products.

Comprehensive Camera Inspection

Cornerstone, with over 45 years of chimney experience in Oklahoma, are specialists in chimney related challenges such as chimney fires, earthquakes, lightning strikes, age deterioration, tree damage, wind, hail, and water issues. One of the key services Cornerstone Chimneys offers is a comprehensive camera inspection, which allows their team to check for gaps, cracks, and other issues that could compromise the integrity of the chimney. This is especially important in Oklahoma, where seismic activity and windstorms can cause chimneys to shift, leading to joint strain and potential hazards. “We check the inside and outside to ensure the chimney’s integrity,” Kathy said, “because it’s all about protecting your investment and your family’s safety.”

Cornerstone also provides full masonry rebuilds, fireplace removal and installation, wood-burning to gas log conversions, wood stove installation, hearth and fireplace facing remodeling, wood chase and siding replacements.

Top Installer of HeatShield

Cornerstone Chimneys is a top installer of HeatShield, a high-tech mortar that can restore the safety of aging chimneys. In addition, they offer a range of services, from chimney sweeps and repairs to gas fireplace installation and service. No matter the need, the Randalls and their team approach every job with the latest tools, technology, and training. “We send our guys to learn from the best of the best at the Chimney Safety Institute of America, They’re experts in their field, offering peace of mind to our customers,” Kathy added.

Commitment to Community

But it’s not just about technical expertise—Cornerstone Chimneys is deeply committed to building a strong, supportive community for both their customers and employees. When the Randall family purchased the business, they made it a priority to hire veterans, helping them transition to civilian life by providing meaningful work and a sense of purpose. “We believe in investing, certification, and ongoing training of our team,” Kathy explained. “We offer top-notch training and foster a supportive environment where everyone, whether they’re veterans or civilians, has the tools to improve and better themselves.”

This commitment extends beyond just the workplace. “Our purpose internally is to build a community that takes care of each other,” Kathy said, “and that’s the same approach we take with our clients.” The Randalls are dedicated to creating a team that not only excels professionally, but also feels valued and supported in every aspect of their lives.

As a veteran-owned business, Cornerstone Chimneys also offers discounts to veterans and first responders, a nod to their own backgrounds in public service. “Once you’re our customer, we want to take care of you,” Kathy emphasized.
