We show up
When we say we'll be there, we're there. If something changes, you hear it from us first — not after you've spent the morning waiting.
About
Firm Foundation Property Services is a family-run excavation and landscaping contractor in Mount Pleasant, South Carolina, run by Josiah Lammers. The work goes back a lot further than the company does.


Our Story
Josiah was barely old enough to walk the first time his Uncle Donnie sat him in an excavator.
He grew up around that work — moving dirt, learning grade, learning from a man who believed a job wasn’t finished until it was finished right.
He runs Firm Foundation the same way.

Where the name comes from
Matthew 7:24 is where the name came from — the person who builds on solid rock is the one whose house stands. It’s also the standard: get the base right and everything on top of it holds. True of a driveway, a patio, a drainage line.
The rest of it is Josiah’s own — the values he works by and the mission he wrote for himself: live a life of integrity.
How We Work
Josiah’s own mission statement is to live a life of integrity. On a job site, that cashes out as four fairly unglamorous things.
When we say we'll be there, we're there. If something changes, you hear it from us first — not after you've spent the morning waiting.
Every quote starts with walking the property. You get a real number and a straight answer about what the work will and won't fix.
Spoils hauled off, debris gone, the site left the way we'd want ours left. Every job, not just the big ones.
Family run and based in Mount Pleasant. We work the same roads we live on, which is the best reason there is to do it right.
