What Should Be Included in a Slab-Leak Repair Estimate?

Use this checklist to compare diagnosis, access, materials, restoration, permits, testing, warranty, exclusions, and change conditions.

Key Takeaways

  • The estimate should identify the confirmed system and proposed method.
  • Access and restoration must be explicit.
  • Materials, testing, permits, warranty, and exclusions belong in writing.
  • Change-order triggers should be described before work.

Diagnosis and Proposed Repair

The document should identify the tested line, supporting findings, suspected or exposed failure area, and why direct repair, rerouting, or partial repiping is recommended.

For a reroute, ask for start and end points, fixtures served, route, pipe size and material. For direct access, ask for the expected opening and field-condition limits.

Scope, Exclusions and Responsibility

List water shutoff, protection, demolition, excavation, plumbing, pressure testing, backfill, concrete, drywall, flooring, paint, cleanup, permits, inspection, and disposal.

Any item not included should be labeled clearly so the homeowner can budget for another trade.

Plan for Concealed Conditions

Underground work can reveal different depth, direction, materials, joints, reinforcement, or secondary damage. The estimate should explain how discoveries are documented and priced before extra work proceeds.

Do not rely on verbal promises that conflict with written exclusions.

Check the Technical Scope Before Comparing Prices

The estimate should identify the tested system, suspected location or failed branch, and the evidence supporting the proposed method. For direct repair, look for expected access, pipe material, replacement length, connection method, bedding or protection, pressure testing, backfill, and concrete closure. For rerouting, look for endpoints, fixtures, route, size, material, transitions, supports, insulation, penetrations, valves, and abandonment of the old run.

Vague wording such as “repair slab leak” leaves important decisions open. Ask whether the amount changes if the pipe is deeper, the opening shifts, reinforcement is encountered, another failed section appears, or an undocumented tee changes the route. The contractor should describe how concealed conditions are photographed, priced, and approved before extra work proceeds.

When comparing contractors, place each proposal into the same worksheet rather than comparing the original formats. Add allowances for excluded flooring, paint, permits, cleanup, and drying so every option reflects a realistic completed project. If one proposal recommends direct repair and another recommends rerouting, ask each contractor to explain or price the alternative; this reveals whether the difference comes from evidence, access, or preference.

Before signing, confirm the legal company name, contractor information, insurance requirements, payment recipient, and who will supervise subcontractors. Attach the detection report, drawings, finish allowances, and approved selections to the agreement. A complete attachment package prevents important scope details from being separated from the price and signature pages.

Check Restoration, Schedule, Warranty, and Payment Terms

List every finish and support task: furniture moving, dust protection, water extraction, drying, flooring removal, concrete, tile, carpet, drywall, texture, paint, cabinets, debris, cleaning, permit, and inspection. Mark each as included, excluded, allowance, or owner responsibility. Also confirm who supplies matching materials and what happens when an exact match is unavailable.

The agreement should state start conditions, expected water shutoff, project sequence, inspection hold points, cleanup, payment milestones, cancellation terms, and warranty boundaries. Distinguish workmanship coverage from manufacturer coverage and ask whether detection accuracy, finish matching, or unrelated concealed pipe is excluded. Comparing complete written scopes protects both homeowner and contractor better than choosing the shortest estimate or relying on verbal assurances.

  • Connect the proposed method to documented detection evidence.
  • Define concealed-condition and change-order procedures.
  • Assign every finish, permit, inspection, and cleanup task.
  • Read warranty coverage and exclusions before signing.

Use these supporting resources to move from the current question to the next useful diagnostic or repair decision.

Frequently Asked Questions

Should detection fees be separate?

They may be separate or credited, but the arrangement should be clear and should not make the diagnosis less independent.

Should warranty terms be written?

Yes. Identify duration, covered workmanship or materials, exclusions, transfer terms, and the claim process.

What is a change order?

It documents additional or revised work, price, and schedule after conditions differ from the original scope.

Should cleanup be included?

The estimate should state dust-control and debris-removal responsibilities as well as any final cleaning exclusions.

Practical Next Step

Document what you observed, rule out visible and automatic water uses, and avoid approving invasive work until the affected system and proposed access are explained in writing.
