Anatomy of a sewer quote: a complete sample, section by section

A sample sewer quote broken down section by section: scope, specification, exclusions, unit rates, restoration, payment and warranty.

Short answer

A complete sewer quote names the property and the defect, states the method and pipe specification, draws exact start and end points, lists every line item with a price, spells out exclusions and unit rates for extras, defines restoration, sets a payment schedule tied to milestones, and attaches warranty terms and a post-work video requirement.

Key takeaways
  • A quote is a scope document first and a price second; if the scope is thin, the price is meaningless.
  • Exclusions and unit rates are the parts that decide your final bill — read them first.
  • Anything said on site but missing from the paper should be added before you sign.
  • Use the sample below as a template when you request quotes, so every contractor fills the same structure.
Building sewer and lateral in cross-sectionA house stack drops to the building drain, passes a cleanout and optional backwater valve, then the lateral slopes under the property line to the municipal main. Ownership typically splits at the property line but varies by municipality. FROST PENETRATION (VARIES) STACK ① CLEANOUT ② BACKWATER VALVE (IF INSTALLED) ③ LATERAL — SLOPES TO THE MAIN PROPERTY LINE ④ MUNICIPAL MAIN OWNER SIDE (TYPICAL) CITY SIDE — CONFIRM LOCALLY
Fig. 1From stack to street: where the building drain, cleanout, backwater valve and lateral sit, and where ownership typically changes hands.

01 /What does a complete sewer quote look like?

Below is an illustrative quote for a common job — replacing an 18 m clay lateral under a front lawn in a 1960s house — broken into the sections a good quote contains. The company, address and prices are invented for teaching; the structure is what matters.

02 /Section 1: Header and basis of quote

The header identifies who, where and on what evidence the quote is based. It should reference the camera inspection by date so everyone prices the same diagnosis.

  • Contractor legal name, address, phone, business number, and quote number and date.
  • Customer name and property address.
  • Basis: "Camera inspection of [date], video file provided, showing root intrusion at joints from 3 m to 17 m, offset joint at 9.5 m, belly holding approximately 25% of pipe diameter from 11 m to 13 m."
  • Validity period: "Price valid for 30 days."

If a quote has no basis line, ask what evidence it was priced from. See sewer camera inspection cost for what the footage should contain.

03 /Section 2: Scope of work

Scope is the most important section. It must say what will be done, where it starts and ends, and how.

  1. Obtain plumbing permit and arrange utility locates.
  2. Excavate open trench from the front foundation wall to the property line, approximately 18 m, depth approximately 1.8–2.2 m.
  3. Remove existing 100 mm vitrified clay pipe.
  4. Install new 100 mm PVC SDR 28 sewer pipe on compacted granular bedding at code-compliant slope.
  5. Connect to existing cast iron at the foundation wall with a shielded transition coupling.
  6. Connect to existing service at the property line with a shielded coupling.
  7. Install a new two-way exterior cleanout at the foundation.
  8. Arrange and attend municipal inspection before backfill.
  9. Backfill in compacted lifts; remove surplus soil and old pipe.
  10. Restore surface: topsoil and sod over trench.
  11. Provide recorded post-work camera video of the new line from cleanout to property line.
Where drain cleanouts and access points areFour access points: a cleanout at the base of the stack, a basement floor drain with its trap, a toilet pulled from its flange, and an exterior cleanout riser in the yard. ③ TOILET PULL ① STACK CLEANOUT ② FLOOR DRAIN (TRAP) ④ EXTERIOR CLEANOUT THE BEST ACCESS IS THE ONE CLOSEST TO THE CLOG WITH THE FEWEST BENDS
Fig. 2Step 7 of the scope adds a two-way exterior cleanout at the foundation. Where a cleanout sits decides how cheaply the line can be cleaned or scoped later.

Notice that the sag is solved by open-cut replacement, which is why this sample is not trenchless. Compare the method against the footage using trenchless lining vs pipe bursting.

04 /Section 3: Price breakdown

Sample price breakdown — illustrative planning figures (CAD, 2026, before tax)
LineDescriptionAmount
1Mobilisation, locates coordination, site setup$900
2Permit and inspection fees$350
3Excavation and removal, 18 m at approx. 2 m depth, including shoring as required$7,200
4Pipe, fittings, bedding material$1,100
5Pipe installation and connections (2 transition couplings)$2,400
6Exterior two-way cleanout$1,100
7Backfill, compaction, soil and pipe disposal$1,600
8Topsoil and sod restoration, approx. 30 m²$900
9Post-work camera videoIncluded
Subtotal$15,550
GST (5%, Alberta example)$777.50
Total$16,327.50

Per-metre check: subtract permit ($350), cleanout ($1,100) and sod ($900) from the subtotal, leaving $13,200 for 18 m — about $733 per metre. That sits inside the typical open-cut range for moderate depth under lawn. Sewer line cost per foot explains the method and why short runs read higher; run your own numbers in the sewer cost estimator.

05 /Section 4: Exclusions and unit rates

Exclusions tell you what could still cost money. Unit rates cap the cost of surprises. Read this section before the price.

Sample exclusions and unit rates — illustrative (CAD, 2026)
ItemStatusUnit rate if required
Work beyond property line (city service or main)ExcludedQuoted separately after city confirmation
Rock or concrete obstructionExcluded$250/hour breaking, with written approval
Additional pipe length beyond 18 mExcluded$650/metre
Dewatering if groundwater encounteredExcluded$450/day
Interior work inside foundationExcludedQuoted separately
Irrigation, landscape lighting, fence repairExcludedTime and materials at $95/hour plus materials
Tree removal or root pruningExcludedBy owner or arborist

A clause should follow: "No additional work will be performed without the owner's written approval of the scope and price." If it is missing, ask for it.

06 /Section 5: Schedule, payment and warranty

  • Schedule: start within 10 business days of permit issue; 2–3 site days; sod within 7 days of backfill, weather permitting. No drainage from the house during the tie-in, expected 6–10 hours.
  • Payment: 10% deposit on signing; 60% on completion of pipe installation and passed inspection; 30% on restoration and delivery of post-work video.
  • Warranty: workmanship on new pipe and connections for a stated period from completion; settlement of trench backfill corrected within the first year; pipe material covered by manufacturer's terms; exclusions listed (for example damage from future tree roots at unreplaced pipe beyond the property line, misuse, or third-party excavation).
  • Insurance: certificate of liability insurance and workers' compensation clearance attached.
  • Signatures and date for both parties.

Deposit size, progress payments and any financing offered with the quote are compared in paying for sewer repairs. If the job is bigger than the budget, that guide also covers staging the work.

07 /How would a trenchless version of this quote differ?

If the footage showed no belly, a lining quote for the same 18 m run would move money between lines rather than remove it. Excavation shrinks or disappears; pre-cleaning, liner material and reinstatements appear.

Open-cut vs lining version of the same sample — illustrative planning figures (CAD, 2026)
LineOpen-cut sampleLining version
Mobilisation and setup$900$1,500
Permit$350$350
Excavation$7,200$0–$3,000 (one pit if no usable cleanout)
Pre-cleaning and descalingNot needed$600–$1,500
Pipe or liner material and install$3,500$9,000–$13,000
Branch reinstatementsNot applicable$0–$1,200
Cleanout$1,100$1,100
Backfill and restoration$2,500$0–$1,000
Post-work videoIncludedIncluded

The lining version also changes the scope wording: it should state liner type and thickness, cure method, the no-use period, and how the liner ends are sealed at the house and at the property line. Compare the two versions using trenchless lining vs pipe bursting cost.

08 /How to use this sample

  1. Send it as a template

    When requesting quotes, ask each contractor to use these five sections so the documents line up.

  2. Mark gaps

    Highlight any section missing from a quote and ask for it in writing.

  3. Normalise

    Enter every quote in the quote comparison worksheet, then settle the details with the line-by-line comparison method.

  4. Ask the 15 questions

    Use the pre-signing questions to fill anything the quote leaves open.

FAQQuestions people ask

What should be included in a sewer line replacement quote?

A basis referencing the camera inspection, a detailed scope with start and end points, pipe specification, itemised prices, exclusions with unit rates, restoration details, schedule, payment terms, warranty text and proof of insurance.

Should a sewer quote include the permit?

Ideally yes. The contractor should pull the permit, include the fee and arrange inspections. "Permit by owner" moves responsibility and cost to you.

How long should a sewer quote be valid?

Many contractors hold prices for 14 to 30 days. Material price changes can shorten this. The validity period should be printed on the quote.

What is a unit rate on a sewer quote?

A unit rate is a price per unit — per metre, per hour, per pit — for work that may or may not be needed. It caps the cost of surprises and lets you compare how contractors price risk.

Is a one-line sewer quote acceptable?

Not for repair or replacement. A single line such as "replace sewer line" cannot be compared or enforced. Ask for the five-section structure described on this page.

Does the quote need a site sketch?

It is not required but it helps. A simple sketch showing the house, cleanout, route, property line and work zone prevents most scope disputes.
