What Sets Us Apart

  • Built on Purpose

    We believe work is more than just work. It’s a calling. That’s why we show up, follow through, and treat every property like it matters—because it does.

  • Reliable. Period.

    We do what we say we’ll do—and if we miss your call, we always follow up. We’ve earned long-term trust by simply being dependable.

  • Hands-On Quality

    From snow and lawn to property cleanups, we don’t cut corners. We notice the small things—because that’s what makes a place feel well-kept.

  • Local & Personal

    We’re not a faceless franchise. We live here. We work here. And we care about every job and every relationship we build.

About us

Cornerstone Service Group, LLC was built to be the opposite of what we kept seeing — companies that overpromise and underdeliver, miss details, ghost clients, or do just enough to check a box. That’s not how we’re wired. We’re a woman-owned, small local company led by people who care deeply about showing up, following through, and honoring the work we do. Our name, Cornerstone, is more than a brand—it’s a reminder of our foundation. In both business and life, we aim to build on something solid, something lasting. From snow to summer, quick cleanups to ongoing maintenance, we do the jobs others overlook—and we do them right. Whether you’re a property manager juggling five sites or a homeowner tired of chasing flaky contractors, we’re here to lighten your load and make your place shine. We may not always pick up on the first ring (we wear a lot of hats), but we will always follow up. Because that’s who we are.
