Spring Home Inspection Guide

Winter’s aftermath is on full display. Here’s what to watch for when buying a Michigan home in spring.

Why Spring Is Different

The Thaw Reveals What Winter Was Hiding

Spring is Michigan's most revealing inspection season. Snow melts, ice recedes, and the damage from months of freeze-thaw cycles becomes visible for the first time. Foundation cracks widen, gutters that failed during ice storms show their damage, and basement moisture problems spike as the ground thaws and water finds its way in.

This works in your favor as a buyer. Problems that would be invisible under two feet of snow in January are plainly visible in April. A spring inspection can catch issues that a winter or summer inspection might miss entirely.

Issue #1

Foundation Cracks & Frost Heave Damage

Michigan's freeze-thaw cycles are the leading cause of foundation damage in the region. Water seeps into small cracks in fall, freezes and expands in winter, and by spring those cracks are noticeably wider. Clay-heavy soils in Oakland and Macomb Counties add lateral pressure to basement walls, making this even more common.

Stair-step cracks in block walls — follow the mortar joints, usually starting at corners or window openings
Horizontal cracks — the most concerning type, indicating inward wall pressure from expanding soil
Doors or windows that stick — this can indicate foundation movement or settling
Uneven floors — use a marble or ball to check if floors slope noticeably in any direction

Spring advantage: Fresh cracks from this winter's freeze cycle are easier to spot now than at any other time of year. The contrast between old patched cracks and new ones tells you a lot about whether the foundation is stable or actively moving.

Issue #2

Grading, Drainage & Snowmelt Runoff

When snow melts, water has to go somewhere. If the ground around the house slopes toward the foundation instead of away from it, that water is heading straight into the basement. Spring is the only season where you can see the drainage system under real stress.

Ground should slope away from the foundation on all sides — at least 6 inches of drop over the first 10 feet
Downspouts should discharge at least 4-6 feet from the foundation, not pooling next to it
Window wells should be clear of debris and have functioning drains
Sump pump — if there's a sump pit, make sure the pump runs and discharges away from the house. Spring is when it works hardest

What to ask: If you're touring a home after a recent rain or snowmelt, look at the soil directly around the foundation. Wet soil, standing water, or erosion channels are all signs of poor grading that a sunny-day visit might not reveal.

Issue #3

Roof Condition After Winter

Michigan roofs take a beating from November through March. By spring, the evidence is visible: missing shingles from wind storms, cracked or curled shingles from ice dam cycles, damaged flashing around chimneys and vents, and sagging or detached gutters from ice weight.

Missing or lifted shingles — visible from the ground, especially on the north-facing slope
Staining on ceilings or in the attic — water stains indicate leaks that may have occurred during winter but weren't noticed
Gutter condition — sagging, detached, or crushed gutters from ice load
Flashing around chimneys, vents, and skylights — ice can pull flashing loose, creating entry points for water

Spring advantage: Ice dams are gone, so you can't see them anymore. But their damage — water stains in the attic, shingle deterioration along the eaves, and soft spots in the roof deck — is still visible. Ask the inspector to pay close attention to the attic for signs of past ice dam intrusion.

Issue #4

Basement Moisture & Sump Pump Stress

Spring is the worst season for basement moisture in Michigan. The ground is saturated from snowmelt, the water table is high, and any weakness in the foundation or waterproofing system will show itself now. If you're going to find a wet basement problem, spring is when it reveals itself.

Efflorescence — white mineral deposits on basement walls mean water is migrating through the concrete
Musty smell — indicates active or recent moisture even if you can't see it
Water stains or tide marks — lines on walls showing where water has risen in the past
Sump pump running constantly — normal in spring, but if it's running every few minutes, the drainage load is high
Dehumidifier running — if the seller has a dehumidifier in the basement, ask how often it fills up

What to ask: "Has this basement ever had water?" If the answer is no but you see a sump pump, dehumidifier, and fresh paint on the lower walls, the physical evidence tells a different story.

Issue #5

Exterior Assessment — Siding, Walks & Landscaping

Winter doesn't just affect the roof and foundation. Sidewalks heave and crack, concrete stoops shift, siding takes impact damage from ice and debris, and landscaping reveals grading problems once the snow is gone.

Concrete walks and driveways — look for heaving, cracking, and settlement. Trip hazards are safety issues.
Siding and trim — cracks, warping, or gaps where water can penetrate
Caulking around windows and doors — winter expansion/contraction breaks caulk seals
Trees and branches — overhanging limbs that could damage the roof, and roots that may be affecting the foundation or sewer line

Spring Inspection Checklist

Questions to Ask Your Inspector in Spring

"Are these foundation cracks new from this winter, or old and stable?"

"Is the grading directing water toward or away from the house?"

"Is there evidence of ice dam damage in the attic?"

"How old is the sump pump, and is the backup working?"

"Are there signs of past basement flooding?"

"Would you recommend a sewer scope given the age of this home?"

"Should we add radon testing?" (spring ventilation changes can affect levels)
