About Keystone

The Most Trusted Project Leader.

Keystone Construction helps clients make confident construction decisions by combining thoughtful planning, experienced leadership, trusted partnerships, and disciplined execution. We're not the cheapest contractor — we're the most trusted project leader.

Who We Are

A Construction and Project Management Firm.

Keystone Construction specializes in guiding commercial and residential projects from concept through completion. We sell peace of mind and reduced uncertainty — not labor. When you work with us, you're working with an owner's representative who plans thoroughly and communicates clearly at every step.

Keystone Construction is the licensed general-contracting flagship of Keystone Creative Solutions, LLC. Our original companies — Keystone Home Solutions and Keystone Painting Solutions — now operate as specialized divisions beneath it.

The Keystone Method

Confidence Through Preparation.

Most construction problems come from one thing: a lack of process. The Keystone Method is our answer — six phases that make every project predictable, from the first conversation through long-term support.

Consult

We listen, assess the space, and understand what success looks like for your project before recommending anything.

Plan

Scope, budget, and timeline are defined and locked before any work begins. No scope creep, no sticker shock.

Design

We coordinate design and engineering so the plan is buildable, budgeted, and complete before construction.

Build

Daily oversight and trade coordination, with each phase inspected before the next begins.

Deliver

Final inspection, punch list, and a walkthrough you sign off on yourself before we call it done.

Support

We stand behind the work and stay reachable long after the project closes.

The Keystone Standard

What We Hold Ourselves To

Prepared, Not Reactive

We do the planning most contractors skip, so problems are solved on paper before they become expensive in the field.

One Team, Accountable

One point of contact owns the outcome. No blame-shifting between subs, no gaps where things fall through.

III

Clear, Direct Communication

You always know where your project stands. We tell you what's true, not what's easy to hear.

Leadership

Brian Hernandez

Brian Hernandez is the owner, qualifier, and licensed general contractor behind Keystone Construction — Florida Certified General Contractor CGC1541355. He is the expertise the company is built on.

With 15+ years across construction, renovation, and real estate development in South Florida, Brian leads projects the way an owner's representative would: personally involved from the first walkthrough through final sign-off. When you hire Keystone, you work with experienced leadership directly.

Trade Partners

Trusted Partnerships, Not Strangers Off a List.

A project is only as good as the people who build it. We work with a vetted network of trade partners — engineers, architects, and specialty subs — many of whom have worked with us for years. That continuity is part of why our projects stay on schedule and meet the standard our clients expect.

Community

Built Here. Invested Here.

South Florida isn't just our service area — it's home. We understand the local permitting process, HOA requirements, inspection standards, and climate conditions that shape every build here, because we've been building in these communities for over fifteen years.
