We follow the golden rule.

Varnishing the Deck
The Denner Company Mission

The Denner company strives to give better than expected, high-quality repair services to home and business owners in the Oklahoma City Metro. We treat each customer interaction with integrity, respect and a service-minded attitude.


Looking ahead, we strive to learn new ways to improve, protect and conserve our precious environment. We are focusing on green building, sustainable materials, waste management and environmentally sound construction practices for today and the future.

Built On Values

The Denner Company was founded in 1995 by John Denner, a native Oklahoman. The company was built on three basic fundamentals that are widely dismissed by contractors today: We show up on time. We promptly return all phone calls. And we do what we say we'll do. Those values are even more important today than they were over 20 years ago. 


Assurance Guaranteed

The Denner Company is fully licensed and insured. We promise quality and longevity on all projects and treat every property and customer with respect.
