Estate-Quality Repiping for Hillsborough's Finest Homes
Even Hillsborough's premium original copper (not galvanized like lesser cities) eventually fails after 80-100 years. But repiping an estate is fundamentally different from a tract home — complex routing through multiple wings, multi-story construction, custom finishes that can't be replicated, coordination with household schedules, and systems 3-5x the size of typical homes. Materials must match estate quality — Type L copper, ProPress fittings, not the minimum-code materials used in standard construction.
Repiping Services for Hillsborough Estates
Why Hillsborough Estates Choose GB Plumbing
Finish-First Approach
We plan routing to minimize access points in custom walls, marble, and woodwork. Every penetration is carefully considered to protect irreplaceable finishes — because in Hillsborough, the walls themselves are often works of art that cannot be replicated.
Phased Scheduling
Repipe wing-by-wing so your family maintains use of most of the home during work. Only the section being actively repiped loses water service — the rest of the home functions normally with full water pressure and hot water availability.
Premium Materials Only
Type L copper, ProPress fittings, commercial-grade valves — matching estate standards throughout. We never use minimum-code materials in premium homes. Your repipe will last another 80-100 years, matching the quality your home was originally built with.
Our Estate Repiping Process
Comprehensive System Survey & Route Planning
We map your entire existing system, identify optimal routing for new pipes, and plan access points that minimize impact on finishes. This detailed survey prevents surprises during installation.
Phased Schedule with Household Coordination
We develop a wing-by-wing schedule coordinated with your family's routine, household staff, and any events. You'll know exactly which areas are affected each day.
Wing-by-Wing Installation with Finish Protection
Professional coverings protect all surfaces. New Type L copper is installed with ProPress fittings, tested section by section, and concealed with minimal wall disruption.

"The phased approach was brilliant — we lived in the east wing while they repiped the west, then switched. Never felt displaced from our own home."
— Hillsborough Estate Owner Google Review
"Our 1928 copper finally gave out after 95 years. GB replaced it all with Type L copper and you can't even tell the walls were opened. Masterful work."
— Historic Hillsborough Homeowner Google Review
"Three wings, two stories, guest house — they coordinated the entire repipe like a military operation. Every phase on schedule, every finish protected."
— West Hillsborough Resident Google Review
"I manage several Hillsborough properties. GB repiped an occupied estate with minimal disruption — the family barely noticed. That's the standard I expect."
— Hillsborough Property Manager Google Review
"Italian marble, custom millwork, hand-painted walls — they protected everything perfectly. Not a single scratch or mark after a full whole-house repipe."
— North Hillsborough Homeowner Google Review
"Water pressure went from disappointing to incredible after the repipe. Every shower, every faucet — like a completely different house. Should have done this years ago."
