Why Cornerstone
We started Cornerstone because we believe that good work matters — not just as a service, but as a way of life. We're a Reformed Christian-owned small business based in Worcester, MA, serving homeowners and businesses across the greater Worcester area.
We show up when we say we will. We protect your landscaping. We don't rush a job to get to the next one. And when it's done, it looks right — because that's the standard we hold ourselves to.

Cornerstone is a Reformed Christian-owned business. The name isn't incidental — a cornerstone is the first stone set in a foundation, the one everything else aligns to.
For us, that foundation is Christ. And that changes everything about why we work the way we do. We don't do good work to impress customers or build a reputation. We do it because we believe that excellent work — done honestly, with care — is an act of worship.
Abraham Kuyper said it plainly: "There is not a square inch in the whole domain of our human existence over which Christ does not cry: Mine!" Every job we take is part of that domain. We take it seriously because Yahweh is Lord of all, including our work.
"He has told you, O man, what is good; and what does the Lord require of you but to do justice, and to love kindness, and to walk humbly with your God."
