When Minnesota snow finally melts in late March, your patio, retaining wall, and walkways tell you how well they were built. Small issues caught early are cheap to fix. Ignored damage compounds across the next winter. Here is the walk-through checklist pros use each spring.

Patios: What to Inspect
Walk the entire patio surface and look for:
- Pavers that have risen above or sunk below the finished surface (frost heave)
- Polymeric sand that has washed out of joints
- Cracks running across concrete pavers (usually sub-base failure)
- Separation between patio and house foundation
- Standing water that did not drain
A half-inch lift or settlement is fixable. More than an inch usually signals base failure that needs a larger repair.
Retaining Walls: The Priorities
Walls that survived a rough Minnesota winter still need inspection. Look for:
- Leaning or bulging (sign of pressure, drainage failure, or loose geogrid)
- Gaps between wall blocks (can signal base settlement)
- Soil eroding from behind or over the top
- Drain tile outlets blocked or flooded
- Efflorescence (white mineral deposits) on block faces
Leaning walls do not self-correct. Get a professional assessment before another winter stacks pressure on the wall.
Walkways and Steps
Steps are where winter damage shows first. Check:
- Step treads level and secure (should not rock)
- Risers plumb (not tilted forward or back)
- Handrails solid in their footings
- Walkway pavers flush and level with no lifted edges
Trip hazards from winter heaving are one of the most common spring repair calls.
What to Fix Now vs. Monitor
Fix right away: anything creating trip hazards, standing water near the foundation, or wall movement. Monitor through summer: minor joint sand loss, light efflorescence, small cosmetic cracks in individual pavers.
Frequently Asked Questions
How much patio lift is serious?
Up to half an inch of seasonal movement is common and usually reversible. Over half an inch, or damage that persists through summer, signals a base or drainage problem that needs a contractor.
Can I repair winter patio damage myself?
Joint sand refills and minor paver releveling are DIY-friendly. Anything involving base work, drainage, or more than 10 percent of the patio surface should go to a professional.
How do I know if my retaining wall is leaning?
Stand back 20 feet and sight along the wall. A plumb bob or a digital level on top of the wall blocks confirms. Even a 2-degree lean from plumb is cause for concern.
