A disclosure that says the sewer line was repaired is good news and a question at the same time. A properly done repair with paperwork and footage is one of the better things a buyer can inherit, because the most expensive buried component of the house has been dealt with. A repair that was done cheaply, partially or without a permit is a problem with a receipt attached. The buyer’s job is to tell the two apart before closing.
Quick answer: ask for the repair invoice, the permit and final inspection, the contractor’s warranty, and the before and after camera footage. Then have the line scoped again from the cleanout to the main with the repaired section identified by distance. A good repair shows a smooth transition into sound pipe at both ends, correct slope, no debris and no standing water; a liner shows a smooth continuous surface with clean ends and open reinstatements. Treat a repair with no footage and no permit as unverified and price it that way.
The paperwork
Invoice with the method, the footage range and the date. Permit and the municipality’s final inspection sign-off, where one was required. Contractor’s warranty, and whether it transfers to a new owner. Before footage showing the defect and after footage showing the repair. A seller who has all four has a repair worth believing; one who has none has a story. Disclosure rules cover what the seller must tell.
Reading the before footage
The before footage tells the buyer what was wrong and where, and therefore what the repair should have addressed. A collapsed section at 42 ft should correspond to a replaced section at 42 ft; roots at every joint should correspond to a whole-line liner, not a spot repair at one joint. Where the before footage shows more than the repair covered, the uncovered defects are still in the pipe.
Reading the after footage
With the counter on screen, the after footage should show the camera entering sound pipe, reaching the repaired section at the stated distance, passing through it and continuing to the main. Look for a smooth transition at each end, no step or lip, no debris, no standing water in the repaired section, and the pipe beyond it in the condition the before footage showed. Verifying a liner and re-inspecting after repair cover what to look for.
Your own scope
Footage from the seller’s contractor is evidence from an interested party. A buyer’s own scope, to the main, with the repaired section identified by distance from the paperwork, is the check. It costs a few hundred dollars and it is the only way to know the repair is still sound today, since bellies develop and liners can shift. The complete sewer scope guide covers ordering it.
What a good spot repair looks like
A section of new pipe, usually PVC, joined to the old pipe at each end with proper couplings. On camera: a change of material at a clean joint, a few feet of smooth new pipe at the right slope, another clean joint back to the old material. The old pipe either side should be sound; a spot repair in the middle of a failing line fixed one spot. Spot repair vs replacement explains when each is right.
What a good liner looks like
A continuous smooth surface from the entry to the end of the lined section, no wrinkles or folds, no soft spots, clean cut ends, and every branch connection reopened with a clean reinstatement cut. Lifted liner ends, wrinkles that catch debris, a reinstatement missed so a branch is blocked, or a liner installed over a belly so water still stands are the common faults. Inspecting a lined sewer goes deeper.
What a good replacement looks like
New pipe from the house to the main, or from the house to the property line where the utility owns the rest, with a new cleanout and a proper connection at the tap. On camera: uniform new material, correct slope, clean joints, a sound tap. A replacement that stops at the property line leaves the public section old; ask who owns it.
Signs of a bad repair
No permit where one was required. No after footage. A repair that does not match the before footage. Standing water in or just downstream of the repaired section. A lip or offset at a transition. A liner with wrinkles or a blocked branch. Debris left in the pipe. A cleanout that was promised and not installed. Any of these is a reason to get a quote for making it right and to negotiate.
Warranty transfer
Many lining and repair warranties are to the original customer and do not transfer. Ask the contractor directly whether the warranty will cover the new owner and get it in writing. A transferable warranty backed by a contractor still in business is worth real money; a non-transferable one is worth nothing to the buyer. See repair warranties and verification.
Pricing it
A verified repair is a plus and should not be negotiated down. An unverified repair is priced as an unknown: get a quote for a scope and for making good whatever the scope finds, and negotiate from that. Negotiating sewer repairs covers the process.
Common questions
The seller says the sewer was replaced. Do I still need a scope?
Yes. It confirms the replacement exists, covers the whole line and is sound today, and it is your baseline for the future.
Should the repair have a permit?
Almost everywhere, for anything beyond cleaning. A repair without one may need to be inspected or redone to satisfy a lender or a future buyer.
Does a sewer liner warranty transfer to a new owner?
Sometimes. Ask the contractor in writing; do not rely on the seller’s assurance.
