Home / Services / Foundation Repair / Royal Oak, MI
Royal Oak basements are some of the trickiest in Southeast Michigan — small lots, old block foundations, and original 1920s tile drainage that's mostly clogged. We fix them right.
Royal Oak foundation repair work is dominated by hairline crack injection on the city's older block and brick foundations. Most 1920s–1940s Royal Oak homes show some degree of foundation cracking from 90+ years of settling and freeze-thaw, but very little of it is actively structural — we monitor more cracks than we repair. The 30-second test we use: if you can fit a pencil tip into the crack, it's wider than 1/16" and worth a real look. If not, it's almost certainly cosmetic.
When repair is needed, it's typically polyurethane crack injection for active leaks ($400–$1,200 per crack), carbon-fiber straps for occasional early-stage block bowing ($600–$900 per strap), and very rarely helical piers for actual footing settlement. Royal Oak's small lots and short footing depths mean piers are uncommon — typical Royal Oak foundations sit at frost-line depth with adequate bearing for the original construction load.

How we approach it
Most foundation issues homeowners panic about are dormant. They happened years ago and haven't moved since. The fix is sealing, not bracing. Active movement is rare but serious. We use crack gauges on the first visit when it isn't obvious — so the right fix becomes obvious.
We've spent thirty years walking into homes where the first contractor quoted $40,000 for a problem that needed $1,200 of work. The mirror situation exists too. We size the repair to the problem, not to a sales target.
Carbon-fiber straps, steel I-beams, helical piers, and push piers all have a place — but only on the right foundation. For active structural movement we bring in a licensed engineer to spec the system and stamp the drawings. Then we install.

Common questions in Royal Oak
Width and direction matter most. Hairline vertical cracks are almost always non-structural — they're shrinkage from the concrete curing. Horizontal cracks, stair-step cracks in block walls, or anything wider than 1/8" warrants immediate attention. We'll look at it for free.
Crack injection: $400–$1,200 per crack. Carbon-fiber straps: $600–$900 per strap, usually 3–5 per wall. Steel I-beams: $3,500–$7,000 per wall. Helical piers: $1,800–$2,500 per pier. We diagnose first, then quote in writing.
Usually not. Walls bow over years, not days. The exception is recent visible movement — a crack that grew last month, a wall that's pushed out an inch since last year. If it's moving, call. If it's looked the same for a decade, you have time to plan.
Rarely. Excavation is appropriate for severe structural damage, lateral pressure failures, and historic foundations needing exterior membrane. For 95% of repairs, interior work is faster, less expensive, and less invasive.
