Why we like Flintco LLC
Pros & Cons
Pros
- Over 118 years of company history since 1906 and 40+ years of dedicated OKC presence since 1984 makes Flintco one of the most historically established and institutionally experienced construction firms operating in the Oklahoma City market.
- BBB A+ rating for the Oklahoma City operation reflects a clean, complaint-free business record maintained across decades of large-scale commercial project delivery in the region.
Cons
- Flintco is primarily a large commercial general contractor and does not typically serve residential or small commercial clients, meaning it is not a practical option for homeowners or small business owners seeking construction services in OKC.
- Not BBB Accredited despite holding an A+ rating, meaning the company has not undergone the full BBB vetting process — a detail that may matter to procurement officers or clients conducting formal contractor qualification processes.
