Union County is rural Upstate South Carolina at its most characteristic — small town, big land, old infrastructure. Sloan Underground runs water, gas, electric, and fiber bores across Union, Jonesville, Buffalo, Carlisle, and the rural back roads of the county. A lot of the work here is replacing aging service lines without destroying what's left of the yards above them.
What does underground utility boring cost in Union?
Residential HDD bores in Union typically start around $1,500–$3,500 for a short driveway crossing. Longer bores, commercial runs, or bores through rockier terrain scale to $4,000–$20,000+. Every Union job gets a free written estimate, usually within 24 hours.
How Union Boring Is Different
Union is defined by its aging infrastructure. The city of Union and the surrounding mill-village neighborhoods still have galvanized and cast-iron water service lines installed 60, 70, even 80 years ago — many original to the textile mill era. These lines leak, lose pressure, and need replacement, but the old neighborhoods also have mature trees, original sidewalks, and small lots where open-cut trenching would cause more damage than it solves. HDD is the fix. Downtown Union has a compact historic core around the courthouse with older commercial buildings and the same preservation considerations as other old Upstate towns. Out in Jonesville, Buffalo, and Carlisle, the county gets more rural — longer driveways, well/septic systems, and patient work on aging infrastructure. Soil is standard Piedmont clay with occasional clay-to-rock transitions.
Why Choose Sloan in Union
Union is on the far east edge of the Upstate, and a lot of Greenville and Spartanburg contractors won't drive that far. We do. It's been part of our service map for decades, and we know the county's utility history — what's in the ground, where the records are wrong, and which streets still run 70-year-old galvanized pipe.

Common Questions About Union Work
Can you replace old galvanized and cast-iron water lines in Union?
Yes — it's one of the most common jobs we run in Union County. The city and surrounding mill-village neighborhoods still have plenty of mid-20th-century galvanized and cast-iron service lines. We bore a new copper or PEX line alongside the old one without trenching, then cut over the service at the meter.
Do you handle rural Union County water line extensions?
Yes. Jonesville, Buffalo, Carlisle, and the rural parts of Union County all have properties with long driveways and aging service infrastructure. We bore new water, gas, or electric service the full length of the drive in a single day.
Do you work around downtown Union's historic core?
Yes. Downtown Union has older commercial buildings and preservation considerations around the courthouse square. HDD avoids the surface disruption that would make trenching incompatible with the downtown streetscape.
