Basement Waterproofing Cost Calculator for Grand Rapids, MI
Pricing a drain, a sump pump or a couple of crack repairs for a home in Grand Rapids, MI? Pick an answer to four short questions and this page works out a rough range from published national rates. It asks for no contact details, and the result is something to compare with a contractor's written estimate, not a price.
Before You Start
Before you start: the floor size you choose stands in for the length of foundation wall around it. The tool prices only the share of that wall you say needs a drain, at the per-foot interior perimeter drain rate, then adds a sump pump and crack injections if you pick them. Three things stay out of the math: digging along the outside of the foundation, egress window wells and wall bracing. Any of them can move a real price a long way, and only a contractor who sees the house can price them.
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project | about $3,000 to $10,000 (average about $5,000) | Fixr national (2026) |
| Interior perimeter drain, per linear foot | $40 to $120 | Fixr national (2026) |
| Sump pump installation | $600 to $2,500 | Fixr national (2026) |
| Epoxy crack injection, per crack | $250 to $1,000 | Fixr national (2026) |
| Waterproof paint or sealant, per sq ft | $1 to $8 | Fixr national (2026) |
Three rows drive the arithmetic: the drain, the pump and the crack rows. The full-project and sealant rows are there for comparison. No Grand Rapids or Michigan cost source exists, so every figure is national. Backwater valves, footing-drain disconnections, sewer laterals and any sump tie-in to a drain or sewer aren't in the calculator; they're plumbing jobs for a licensed plumbing contractor, who prices them. The City's own sewer programs set their own terms, so ask the City about those. The cost guide covers the rest.
