Not every cracked wall needs piers, and an industry paid by the pier has a structural conflict of interest in telling you so. Here’s a decision path that doesn’t require trusting any single salesperson.
Step 1: Inventory the symptoms
Walk the house with the warning-signs guide and write down what you find: crack locations and widths, sticking doors, slopes, separations. Photograph everything with a scale reference and a date.
Step 2: Sort into one of three buckets
Bucket A — cosmetic/stable. Hairline cracks that haven’t changed; no door or floor symptoms. Action: monitor quarterly. Cost: $0.
Bucket B — cyclical/moisture-driven. Symptoms that come and go with the seasons; movement concentrated where drainage is bad, beds are over-watered, or a big tree stands close. Action: fix the moisture first — grading, gutters, consistent watering, maybe a root barrier or drains. Re-assess after a full season. Cost: hundreds to a few thousand — an order of magnitude below underpinning.
Bucket C — progressive/structural. Cracks that widen year over year, doors that stopped latching, slopes you can feel, wide or offset cracks. Action: get real measurements now.
Step 3 (Bucket C): measurements before commitments
An elevation survey — a contractor or engineer mapping the actual heights across your floor — turns opinion into data. Two rules:
- For a five-figure repair, pay a few hundred dollars for an independent structural engineer (one who sells no piers). Their repair plan becomes the spec every contractor bids against.
- Multiple bids, same spec. Pier counts differ between bidders; make the plan fixed and let the price compete.
The questions that keep you safe
- “What happens if I wait six months?” (Legitimate answer for much movement: “probably nothing — monitor it.” A panic answer is a red flag.)
- “What’s causing the movement, and does your scope fix the cause?” (Piers without drainage correction on a ponding lot treat the symptom.)
- “What does the warranty cover, exactly, and does it transfer?”
When waiting is wrong
Movement accelerates when its cause persists: an unrepaired plumbing leak, a drought in full swing, water ponding every storm. And if you’re selling, unaddressed visible movement costs more in negotiation than it costs to fix with a transferable warranty — see the cost guide for the money side.
The honest summary
Most houses in Bucket A stay in Bucket A. Bucket B fixes are cheap and underrated. Bucket C needs data, an engineer, and competitive bids — in that order. Your soil sets the base rate for all of it: check what’s under your city.
