Scope being priced
This guide covers repair or replacement of perimeter drain tile that collects water near the foundation. The scope can be exterior, interior, or targeted to a failed section; the quote should make that distinction clear.
What changes the price
- Whether the work is a targeted repair or replacement of a longer perimeter section.
- Depth, pipe condition, soil, groundwater, and access for excavation or interior slab work.
- Camera inspection, locating, connection points, cleanouts, and discharge requirements.
- Obstacles such as concrete, decks, landscaping, utilities, or finished basement areas.
- Backfill and restoration of the yard, slab, walls, or other disturbed finishes.
What a quote should itemize
- The drain sections being repaired or replaced and the method used to confirm the issue.
- Access work, pipe material, drainage aggregate, fittings, cleanouts, and connection points.
- How the system will be tested and where collected water will discharge.
- Excavation or slab restoration and exterior or interior cleanup.
- Items outside the drainage scope, including waterproofing membranes or landscape rebuilding.
Red flags in a quote
- The quote uses 'drain tile replacement' without defining the pipe length or access method.
- No inspection findings or explanation supports the proposed replacement.
- Discharge, cleanout, or testing details are absent.
- A restoration allowance is not separated from the drainage work.
