If a sewer scope finds roots during a home purchase, find out how severe they are, which joints are affected and whether the pipe is cracked, offset or sagging. Get a clearing-and-camera quote plus a repair quote before your conditions expire, then negotiate a price reduction, credit or seller repair based on those numbers. Light roots in sound pipe are maintenance; heavy roots with defects are a repair.
- Roots in the sewer are common in older homes with trees; the question is severity and pipe condition, not presence alone.
- Ask for the full recording with a distance counter, not just a summary sentence.
- Heavy roots can hide defects; a second look after cleaning shows the real condition.
- Get written repair quotes before your financing and inspection conditions expire.
- Negotiated outcomes include a price reduction, a credit where permitted, a holdback or a seller repair; each has trade-offs.
01 /What does it mean when a sewer scope finds roots?
It means roots have entered the lateral through at least one joint or crack. By itself that is common in older homes with mature trees. What matters is how much root there is, how many joints are involved, whether the pipe shows cracks, offsets, sags or breaks, and what the pipe is made of.
| Finding | What it usually means | Typical response |
|---|---|---|
| Fine roots at one or two joints, pipe otherwise sound | Early intrusion | Cut, then monitor or point repair; modest cost |
| Fine to medium roots at several joints in clay or concrete | Ongoing intrusion along an old line | Budget for cutting cycle or full lining |
| Root ball or mass restricting flow | Active blockage risk | Clear before closing if possible; camera again after clearing |
| Roots plus cracks or offset joints | Structural defects roots are exploiting | Repair quote needed: lining or sectional repair |
| Roots plus sag, collapse or broken pipe | Significant defect | Replacement or bursting quote; possibly major cost |
| Roots at a clay-to-plastic transition | Weak coupling from a past partial repair | Point repair often suitable |
Many inspection reports use the NASSCO PACP approach, which groups root observations as fine, tap, medium and ball, and records whether they are at a joint, in the barrel, or at a lateral or connection. SewerInspector.ca explains those codes in detail, and what roots in a sewer line look like shows how each root type appears on the recording.
02 /Should you ask for the line to be cleaned and re-scoped?
Often, yes. Roots can hide what lies behind them, so an inspection through a root mass may understate cracks and offsets. Where time and the seller allow, clearing the line and running the camera again shows the true condition and gives contractors a sound basis for quoting.
- Ask the seller's permission; clearing is work on their property.
- Agree who pays for the clearing visit.
- Request the recording from both passes, with distances.
- If clearing is not possible before conditions expire, treat the unknown as a risk in your negotiation.
03 /How much should you budget when roots are found?
Budget according to the finding. Light roots in sound pipe may cost a few hundred dollars per cutting visit; many root joints in old clay can justify lining in the high four to low five figures; collapses and sags can push higher.
| Finding | Planning budget | What it covers |
|---|---|---|
| Light roots, sound pipe | $250–$1,000 | Cutting plus camera; ongoing maintenance to follow |
| Roots at one or two defective joints | $1,500–$6,000 | Sectional repair or spot excavation |
| Roots at many joints, pipe holds shape | $6,000–$15,000 | Full CIPP lining of the private lateral |
| Sag, collapse or badly offset pipe | $8,000–$30,000+ | Bursting or open-cut replacement, depth and surface dependent |
The root removal cost guide breaks these down further, and how serious are roots in a sewer line helps you judge whether a finding is maintenance or repair. SewerQuotes.com covers how to compare quotes line by line.
04 /How do buyers negotiate over a root finding?
Buyers usually negotiate a price reduction, a credit, a holdback, or a seller-completed repair, backed by written quotes. The strongest position is specific: this defect, at this distance, with this quoted cost.
Rules on credits and holdbacks differ between provinces, lenders and standard contract forms. Your real estate professional and lawyer can tell you what is available and how to word it. If the seller is doing the work, ask for post-repair camera footage and any transferable warranty.
05 /What questions should you ask before removing conditions?
- What is the pipe material, and are there transitions from past repairs?
- How far was the camera run: to the property line, the main, or less?
- How many joints have roots, and how dense are they?
- Are there cracks, offsets, sags, breaks or collapses?
- What trees — yours, the neighbour's, the boulevard's — are within reach of the route?
- Is there an accessible main cleanout? If not, what would installing one cost?
- Is there a backwater valve, and is it accessible and working?
- Has the seller had the line cleared before, and how often? Ask for invoices.
- Which portion of the lateral is the owner's responsibility in this municipality?
A seller who has had roots cut every year for a decade has told you the cycle; the regrowth guide helps you turn that into a ten-year cost. For responsibility at the property line, see whose tree, whose pipe.
06 /What should you do in the first year after buying?
- Clear the line early
If roots were present and not cleared before closing, schedule cutting soon after possession, ideally before peak growing season.
- Keep the footage
Store the inspection recording and report with your house records. It is your baseline.
- Decide on the fix
Use the quotes gathered during the purchase. If you chose a cycle, book the next visit.
- Check your insurance
Confirm sewer backup coverage and any backwater-valve requirements; the insurance guide lists questions to ask your broker.
- Plan planting
Avoid adding trees over the route; see sewer-safe trees and shrubs.
Use the Root Risk Calculator to rank the trees on your new property, and request quotes when you are ready to compare contractors.
07 /What if the scope could not reach the whole line?
Treat an incomplete scope as an unknown, not a pass. Cameras stop short for several reasons: a root mass the camera cannot push through, standing water in a sag, a severe offset, a collapse, or simply no accessible cleanout. Each of those is itself a finding that deserves an explanation in the report.
| Reason given | What it may indicate | Reasonable next step |
|---|---|---|
| Blocked by roots | Heavy intrusion at that distance | Clear the line, then re-scope |
| Camera submerged in water | Sag or downstream restriction | Clear, then re-scope; budget for a possible section repair |
| Could not pass a joint | Severe offset or broken pipe | Treat as a likely repair; get a quote |
| No suitable access | No main cleanout | Scope through a toilet pull or price a cleanout |
| Operator ran out of cable length | Long lateral | Ask whether the remaining run can be reached from another access |
If you must decide before a second look is possible, build the uncertainty into your offer or conditions, and discuss options with your real estate professional and lawyer.
FAQQuestions people ask
Should I walk away from a house with roots in the sewer line?
Not necessarily. Roots are common in older homes with trees. Base the decision on severity, pipe condition and the cost of the fix, and on whether the price or terms can be adjusted to reflect it.
Who pays for the sewer scope during a home purchase?
The buyer usually pays for inspections they order. Clearing and a second scope may be negotiated with the seller.
Can the seller just cut the roots before closing?
They can, and it restores flow, but cutting does not fix the joints. Ask for footage after cutting so you can see the real condition, and budget for recurrence or repair.
Does a regular home inspection include the sewer line?
Usually not. A standard home inspection typically looks at visible plumbing. A sewer camera inspection is a separate service.
Are roots in the sewer a disclosure item?
Disclosure obligations vary by province and circumstances. Ask the seller directly about sewer history and invoices, and rely on your own inspection rather than assuming disclosure.
How far should a pre-purchase sewer scope go?
Ideally to the city main or at least to the property line, so the entire private portion is seen. Ask the inspector to state how far the camera went.
