Slab Leak Detection & Repair

Locate and repair leak under concrete slab with reroute or spot repair

Slab leak detection using acoustic, pressure, and thermal imaging techniques; repair via either spot excavation + fix or overhead reroute of the affected line. Priced at $1,200–$4,800 for most single-leak cases.

01Scope of Work

reqai rewritable

This proposal covers detection and repair of a slab leak at {{client_address}}. Suspected leak: {{leak_location}}. Repair method: {{repair_method}}.


**Detection** (if not already confirmed)

Isolate hot and cold lines; pressure-test each to identify which line is leaking

Acoustic detection with geophone and listening devices to pinpoint leak location

Thermal imaging to verify (hot-water leaks)

Mark leak location on slab with paint for repair approval


Repair options presented to {{client_name}}:

1. **Spot repair:** Open a 3'x3' section of slab, excavate, replace the leaking section, inspect, patch concrete. Lowest cost but invasive; leaves disturbed finish flooring.

2. **Overhead reroute:** Abandon the slab line; run a new line through the attic (or crawlspace) to reconnect the two endpoints. Preserves flooring; shifts the line out of the slab permanently.

3. **Whole-system repipe:** If multiple leaks are likely (aging copper with pinhole corrosion), consider a whole-home repipe (see separate template).


**This proposal is for:** {{repair_method}}.


**Scope of repair work** (based on method):

**If spot repair:** Saw-cut slab, excavate, expose pipe, cut out failed section, install new Type L copper or PEX section, pressure-test, backfill with gravel, pour new concrete to match thickness, broom finish. Flooring restoration NOT included (tile, LVP, wood) — coordinate with flooring contractor.

**If overhead reroute:** Shut off water, cut and cap existing slab line at both ends (cleanouts), install new Type L copper or PEX-A in attic with hot-water insulation, reconnect to existing distribution, pressure-test, drywall patch at wall penetrations. Flooring remains untouched.


Closeout

Pressure test new repair section at 100 PSI for 30 min

Homeowner walkthrough; restore water service

Document repair with photos for insurance claim (if applicable)

02Schedule

reqai rewritable

Estimated duration:

**Detection:** 2–4 hours

**Spot repair:** 1–2 working days (plus concrete cure time before flooring)

**Overhead reroute:** 1 working day


Start date: {{start_date}}. Water is typically off for 4–8 hours during repair.

03Investment

req

**Total contract price: {{total}}** (inclusive of detection and {{repair_method}})


**Deposit: {{deposit}}** — signing

**Balance: remainder** — at completion and pressure test pass

04Payment Terms

req

Balance due same-day at completion. Some homeowner insurance policies cover slab leak detection AND access repair (not the pipe itself). {{contractor_name}} provides an itemized invoice with labor hours and materials for insurance submission.


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.

05Exclusions

reqai rewritable

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

Flooring restoration after spot repair (tile, hardwood, LVP) — coordinate with flooring contractor

Drywall texture-match beyond basic patch (full texture/paint-match priced separately)

Mold remediation if water damage is discovered (licensed mold remediator required)

Structural drying or water extraction (use a restoration company for insurance claims)

Whole-home repipe (separate template)

06Assumptions

reqai rewritable

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

Leak is a single point on a supply line (not a slab-embedded drain line)

Slab is standard thickness (4–6 inches); post-tensioned slabs require engineering review and are not covered by this scope

Attic access is available for overhead reroute option

07Change Order Process

req

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.

08Warranty

reqai rewritable

{{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.

09Validity & Acceptance

req

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.

Legal notes

  • · If the home has post-tensioned slab construction, STOP — cutting PT cables can cause structural damage or injury. {{contractor_name}} does not cut PT slabs; overhead reroute is the only option and should be pursued.
  • · Insurance carriers typically cover water damage from slab leaks, NOT the pipe repair itself. {{client_name}} should open a claim before repair begins if coverage is in question.
