What should you do if the buyer’s sewer scope finds a problem?
Get the video and report, then get a repair bid from a licensed sewer contractor, and a second opinion if the findings are unclear. Most issues fall into a few categories: root intrusion, a sag (“belly”), cracks or offsets, or old pipe material. Then choose a response: repair before closing, give a credit, adjust the price, or decline. In many Pierce County jurisdictions, the homeowner is responsible for the side sewer from the house to the public main, so confirm what your city or sewer utility covers and what permits a repair needs.
Sewer scopes are common in Western Washington because so many homes have older side sewers. When a buyer’s scope finds something, it can feel like the deal is in trouble.
Usually it isn’t. Sewer findings are one of the most negotiable inspection items, because they’re specific, quotable, and fixable. Here’s how to respond. For the full seller process, see our Pierce County seller guide.
Common findings, in plain English
| Finding | What it usually means |
|---|---|
| Root intrusion | Tree roots entering joints; may need clearing, lining, or replacement |
| Belly or sag | A low spot where water and solids collect; severity varies |
| Crack, break, or offset joint | Pipe damage or separation; may allow leaks or roots |
| Older pipe material | Clay or other older materials that may be near the end of their life |
| Grease or debris buildup | May only need cleaning |
Ask the buyer’s agent for the video and written report. A short clip can tell a contractor much more than a summary.
For how buyers use sewer scopes, see our guide to sewer scope inspections in Pierce County.
Step 1: Get a qualified opinion and a bid
- Have a licensed sewer contractor review the video and quote the repair
- Get a second opinion if the findings or recommended fix seem extreme
- Ask about repair methods: spot repair, trenchless lining, or full replacement, with pros, cons, and warranties
- Ask about permits and timing: repairs may require a permit and inspection, and right-of-way work can add time
Step 2: Confirm who owns what
In many Pierce County jurisdictions, the property owner is responsible for the side sewer from the house to the public main, sometimes including the part under the street. Rules vary by city and sewer district, so confirm with your utility.
Step 3: Choose your response
| Option | When it fits |
|---|---|
| Repair before closing | Clear fix, reliable contractor, time before closing; buyer may want proof of completion |
| Credit at closing | Buyer prefers to choose the contractor; lender allows the credit |
| Price reduction | Larger repair, or credit limits are an issue |
| Decline | Minor or maintenance-level finding, or the market supports your position |
Whatever you choose, get it in writing through your agent. Here’s how sellers think through inspection requests, repairs, and credits.
My take: For a clear sewer defect with a solid bid, a credit is often the cleanest path. The buyer controls the work, and you avoid a closing delay. If the buyer’s loan limits credits, a price adjustment can do the same job.
Step 4: Think about disclosure
Once you know about a sewer defect, it’s part of what you know about the home. If this sale doesn’t close, talk with your agent about updating your disclosures before the next buyer.
How to avoid surprises next time
If you have an older home, consider ordering your own scope before listing. You’ll know the condition, can fix or price for it, and can hand buyers a report up front. Here’s when a pre-listing inspection makes sense.
Frequently Asked Questions
Who pays for sewer line repairs when selling a house?
It’s negotiable. Sellers can repair before closing, offer a credit, adjust the price, or decline. The right choice depends on the finding, the bid, the buyer’s loan, and the market.
Is a belly in a sewer line a big deal?
It depends on how long and deep the sag is and whether it’s causing backups. A licensed sewer contractor can review the video and recommend whether it needs repair or monitoring.
Who is responsible for the side sewer in Pierce County?
In many jurisdictions, the property owner is responsible for the side sewer from the house to the public main. Rules vary by city and sewer utility, so confirm for your address.
Should I repair the sewer line or give the buyer a credit?
A credit is often simpler and avoids delays, while a repair gives the buyer proof of completion. Your agent can help decide based on the timeline and the buyer’s lender rules.
Do I have to disclose a sewer problem if the sale falls through?
Once you know about a defect, it becomes part of what you know about the home. Talk with your agent or attorney about updating your disclosures.
Keep the deal moving
A sewer finding is rarely the end of a sale. With a clear bid and a smart response, most sellers resolve it and close on time.
