Sealing Cracks in Basement Walls
Poured concrete shrinks while curing, so thin vertical or slanted cracks appear in walls of every age. The usual fix is injection: small ports go along the crack on the inside face, and epoxy or polyurethane is pumped in until the gap fills through the wall.
Block tends to split along its mortar in a stair-step line, while stone and brick joints wear and crumble instead. Resin vanishes into hollow cores and rubble voids, so those walls usually get repointing, with weak mortar raked out and fresh mortar packed in. Older masonry is common: Heritage Hill alone counts about 1,300 homes, some going back to the 1840s (APA, 2012).
Most cracks are water problems first. One that runs sideways, keeps widening, or sits in a wall that has begun to bow or lean is worth having looked at soon. A dated pencil mark at each end shows whether it grows.
On the City's building permit application, "Foundation Only" is one of the improvement types. In the City, foundation, excavation and structural repairs generally require a City building permit, and plumbing or sewer work needs its own plumbing permit, pulled by a licensed plumbing contractor; the contractor confirms the list with the Development Center.

With a crack or two, watch the injection row, a 2026 national per-crack range from Fixr rather than a price set here. Repointing, bracing and outside digging carry no sourced number; have each listed on its own estimate line. The cost guide covers what shifts a local total.
How the Work Usually Goes
- Measure and date. Photos with a tape beside each crack.
- Describe the wall. Poured, block, brick or stone, and whether it leaks.
- Options in writing. Each crack, its repair method, the resin or mortar and the warranty.
Why Homeowners Use This Service
You describe the crack once, and one independent local contractor takes it from there. This site is only a referral service: it never visits a house, holds no Michigan residential builder or maintenance and alteration contractor license, writes no estimates and signs no contracts. Contractors may pay it a flat fee to advertise, though a free trial is running now; you pay it nothing and get nothing from it.
Before signing, get the contractor's license number (the Attorney General notes it runs 10 digits) and search it on LARA's online license verification. Michigan's rule says the signed agreement spells out the price, the kind and extent of the work and the grade of materials, with each change also written and signed.
Answers Before You Call
Why is my block wall cracked in a stair-step line?
Mortar is the weakest part of a block wall, so when soil leans on it or the wall shifts, the crack follows the joints. A narrow stair-step crack that holds its width is usually repointed; one that widens or comes with a bulge deserves a contractor's look soon.
Will a sealed crack open up again?
It can. Concrete and mortar shift a little through frost and wet seasons, so a crack that is still active may reopen beside the repair. Ask the contractor what the warranty covers, how long it lasts and whether it transfers to a buyer.
Does crack repair in Grand Rapids need a permit?
It depends on the scope, since bracing or outside digging adds to what the City reviews. In the City, the contractor confirms with the Development Center (616-456-4100, weekdays 7:30 a.m. to 4 p.m.) before starting. Each suburb has its own permit office.
Can I just seal a crack myself?
Store-bought patch kits from a hardware aisle can close a small, dry crack at the surface but seldom reach through the wall, so pressured water often works around them. If water still gets through after rain, injection or repointing usually comes next.
