We’re 317 Seal Inc.—a locally owned concrete washing and sealing company serving Indianapolis and the surrounding neighborhoods. Since 2016, our team has helped homeowners, business owners, and industrial clients protect and extend the life of their concrete surfaces with work that holds up.


This company was built on doing things right. That means no rushed timelines, no guesswork, and no skipping steps. Every surface gets a full inspection, careful prep, pressure cleaning, and a high-grade sealer applied by trained technicians who know exactly what they’re doing. We treat your concrete like it matters, because it does. It’s the foundation of your property, and it deserves care that lasts.


We’ve worked on hundreds of properties across Central Indiana, and the most common thing we hear from new clients is frustration. Many were burned by previous contractors who used cheap sealers, left uneven finishes, or disappeared once the deposit cleared. Our process was designed to be the opposite of that experience. We show up when we say we will, communicate clearly, and follow through without having to be chased down.


Whether you’re a homeowner tired of re-sealing your driveway every year, a business owner looking to clean up high-traffic walkways, or a facilities manager dealing with oil-stained loading bays, we have a system that works. And we’ll walk you through it—step by step.

Our Core Values

Quality Workmanship

We take pride in every job, whether it’s a small driveway or a massive industrial floor. Our work shows up in the details: clean edges, even application, and surfaces that hold up over time. Our reputation depends on the outcome, so we approach every project with full effort and a high standard for what “done” really means.

Clear Communication

You’ll never be left wondering when we’re coming or what’s going on. From your first call to the final walkthrough, we keep you in the loop. If there’s something we need to discuss, we pick up the phone. If there’s a change in the timeline, you’ll hear it from us first. It’s your property, your investment, and your schedule—we respect all three.

Strong Work Ethic

We don’t believe in shortcuts or excuses. Our work ethic comes from experience and a commitment to doing business the right way. You’ll see it in how we prep the surface, how we handle challenges, and how we treat your property. We’re not just here to complete a task—we’re here to earn your trust and deliver something that lasts.
