Sewer Line Replacement (Trenchless or Open-Trench)

This proposal covers replacement of the sewer lateral at {{client_address}} — {{lateral_feet}} from the house cleanout to the city main tap. Existing: {{existing_pipe}}. Install method: {{method}}.

Pre-construction

• Permits from city public works and AHJ

• Call 811 for utility locates (min 3 business days before dig)

• Video inspection of existing line documented and delivered to {{client_name}}

• Coordinate city sewer-main tap inspection (city inspector present for tap)

**Excavation & removal** (open-trench method)

• Protect landscape and hardscape with plywood and tarps

• Excavate trench along lateral route at code-required depth and slope

• Remove existing pipe; dispose per regulations

OR — Trenchless pipe-bursting:

• Small excavation at house cleanout and at city tap only

• Pull new pipe through existing line using pipe-bursting head

• No long trench required; minimal landscape disruption

New pipe install

• Install 4" Schedule 40 PVC (open-trench) or 4" HDPE (pipe-burst) per IPC 2021 standards

• Proper slope (1/4" per foot minimum on 4" pipe)

• New cleanouts at the house and at property line

• New connection to city main with appropriate saddle or tap fitting

• Bed pipe in washed gravel; backfill in lifts with compaction

Restoration

• Restore landscape to rough grade

• Replace sod, mulch, or small shrubs (major landscaping priced separately)

• Replace concrete or hardscape where cut (saw-cut and repour; aesthetic match may be imperfect)

• Final cleanup and haul-off

Inspection & closeout

• AHJ inspection (open-trench: before backfill; trenchless: at cleanouts)

• Final video inspection documenting new line

• Homeowner walkthrough

Estimated duration:

• **Open-trench:** 2–5 working days depending on length and hardscape

• **Trenchless pipe-bursting:** 1–2 working days

Water and sewer service is typically restored by end of each working day; a porta-potty can be staged on-site if needed for longer outages.

Start date: {{start_date}}.

Total contract price: {{total}}

• **Deposit: {{deposit}}** — signing (covers permit and mobilization)

• **Balance: remainder** — upon completion, inspection pass, and restoration walk-through

Balance due at completion. Insurance claims (if covered by homeowner's policy) reimbursed directly by carrier; {{client_name}} remains responsible for the total contract price regardless of insurance outcome.

Invoices are due upon receipt. Payments more than ten (10) calendar days past due accrue a service charge of one and one-half percent (1.5%) per month on the unpaid balance, or the maximum rate permitted by law, whichever is less. {{contractor_name}} reserves the right to stop work and preserve lien rights if any progress payment is not received within five (5) business days of the due date. All retained mechanic's lien, stop notice, and bond rights under applicable state law are preserved.

The following items are specifically NOT included in the contract price and are the responsibility of {{client_name}} unless added by written Change Order:

• Permits, plan-review fees, and jurisdictional inspection fees unless explicitly itemized above

• Repair or remediation of pre-existing code violations discovered during the work

• Asbestos, lead paint, mold, or other hazardous material abatement

• Structural engineering, architectural drawings, or third-party design services

• Finish selections, fixtures, or appliances not listed in the itemized scope

• Work on concealed systems (electrical, plumbing, HVAC, framing) beyond the points of connection identified

• Landscaping restoration beyond returning disturbed areas to rough grade

• Post-completion cleaning beyond construction broom-clean

• Hardscape replacement beyond the cut area (full patio or driveway redo priced separately)

• Landscape restoration beyond rough grade and basic sod repair

• Tree removal along the lateral route (priced separately if required)

• Water line replacement (separate scope; see whole-home repipe for interior supply)

• Point-of-entry backflow preventer (if required by local code)

• City tap fees or sewer connection fees charged by the municipality (reimbursed at cost if paid by contractor)

This proposal is based on the following assumptions. If any assumption is incorrect, the contract price and schedule are subject to adjustment by Change Order:

• Site access is available during normal working hours (7am–5pm, Monday–Saturday)

• Adequate parking is available within 100 feet of the work area

• Electrical power and potable water are available on-site at no cost to contractor

• Existing structural elements, waste lines, water supply, and electrical service are in serviceable condition unless noted

• {{client_name}} will remove personal property, artwork, and valuables from the work area prior to start

• Work is based on a single mobilization; re-mobilization required due to delays outside contractor's control will be billed at current rates

• Existing lateral route can be located via scope or marker

• No major utilities (gas, electric, water) cross the lateral route requiring relocation

• Soil conditions are typical; extreme rock or hardpan may require additional equipment (itemized)

• City tap inspection availability within 5 business days of contractor readiness

Any modification to the scope, specifications, materials, or schedule set forth in this agreement must be authorized in writing as a Change Order signed by both parties before the work is performed. Each Change Order will describe the modified scope, any adjustment to the contract price, and any impact on the schedule. Verbal instructions do not modify this agreement. Additional time and cost associated with unforeseen conditions — including but not limited to concealed rot, asbestos, mold, faulty prior installation, unmarked utilities, or code-required upgrades triggered by the work — will be documented as a Change Order and billed at the rates stated in this proposal or at {{contractor_name}}'s then-current published labor rates, whichever is in effect at the time the condition is discovered.

{{contractor_name}} warrants the workmanship of the installed work for a period of one (1) year from the date of substantial completion. Manufacturer warranties on materials and equipment pass through to {{client_name}} as provided by the manufacturer and are the exclusive source of any material warranty. This warranty does not cover normal wear, abuse, neglect, acts of God, subsequent work performed by others, damage from settlement or movement of the building, or modifications to the installed work performed without written consent. To make a warranty claim, {{client_name}} must notify {{contractor_name}} in writing within thirty (30) days of discovering the alleged defect and allow reasonable access to inspect and repair.

This proposal is valid for 30 days from the proposal date ({{proposal_date}}). Pricing is subject to change after that date due to material market fluctuations and scheduling availability. Acceptance requires signature below and receipt of the deposit amount stated in Payment Terms. Upon acceptance, this proposal, together with any attached specifications and subsequent written Change Orders, constitutes the complete agreement between the parties and supersedes any prior oral or written discussions.
