Pontiac borders Auburn Hills to the west, a few minutes from our office, and its plumbing is the opposite of the new subdivisions nearby. As the Oakland County seat, Pontiac has a deep stock of older housing and downtown buildings, many plumbed with galvanized steel supply lines and cast iron drains that have been in the ground and the walls for sixty, eighty, even a hundred years. That age is the whole story here: pipe that has reached the end of its service life and needs repair or replacement, not a tune-up.
This is plumbing for Pontiac homes and buildings, where the work is about aging pipe more than anything else.
Older homes, galvanized steel and cast iron
The defining feature of Pontiac plumbing is its age. Galvanized supply lines rust from the inside until the water pressure drops to a trickle and the water runs discolored; cast iron drains scale shut and crack at the hubs. Neither is a repair you make once and forget, because the whole system is the same age. When we are called for a leak or a slow drain in an older Pontiac home, the real conversation is usually about how much of the original pipe is left and whether it is time to repipe a section rather than keep patching.
The county seat and its downtown buildings
Pontiac is not only houses. As the county seat it has a downtown of older commercial and mixed-use buildings, many being renovated, and their plumbing carries the same age plus the demands of a business or apartments above a storefront. That work means larger drains, shared stacks, and water service that was sized for a different use than the building has now. We handle the older downtown building the way we handle the older house, by reading what is actually in the walls rather than assuming it matches the code a renovation now wants.
Clay sewer lines, clay soil and backups
Under the older streets, Pontiac’s sewer laterals are often clay, jointed every few feet, and the mature trees that line those streets send roots into every joint. The result is the recurring backup that cabling only buys time against. The heavy clay soil holds water and shifts, which cracks and offsets those old lines further. We camera the lateral to see what is actually happening down there, clear it, and lay out whether a spot repair, a lining or a full replacement is the honest fix for a given line.
Reading the pipe under an older Pontiac basement
An older Pontiac home has rarely been left alone. Owners and handymen across the decades added a copper branch here, a plastic trap there, and capped off a line nobody could explain. Before we quote a repair we trace what is actually there, because the drawing in anyone’s head is usually wrong by a few renovations. That read is what keeps a simple job from turning into a surprise once a wall is open, and it is how we give a straight answer on an old system.

The water pressure in my old Pontiac house keeps dropping. Why?
In an older Pontiac home it is usually galvanized steel supply pipe rusting closed from the inside. The rust narrows the pipe until the flow falls to a trickle and the water can run discolored. It does not reverse, so the fix is replacing the affected lines, often repiping a section or the house rather than chasing one spot at a time.
My Pontiac sewer line backs up every year. Is cabling enough?
Cabling clears it but only buys time, because the cause is usually tree roots in the joints of an old clay lateral that will grow back. We camera the line to see the real condition, then tell you honestly whether regular clearing, a lining or a full replacement is the right call for that particular sewer.
Do you work on older downtown Pontiac buildings, not only houses?
Yes. Downtown Pontiac has older commercial and mixed-use buildings, many under renovation, with shared stacks and water service sized for a former use. We handle those alongside the houses, reading what is actually in the walls rather than assuming it matches what a renovation now needs.
