Southeast Michigan Guide

Top 10 Issues We Find in Michigan Homes

Based on thousands of inspections across Wayne, Oakland, and Macomb Counties. Here’s what to watch for — whether you’re buying, selling, or maintaining.

1

Foundation Cracks & Settlement

Structural ⚠ Found in ~45% of older homes High Risk

Michigan's freeze-thaw cycles are brutal on foundations. Water seeps into tiny cracks, freezes, expands, and widens them year after year. We see this in nearly half of homes over 30 years old — especially in Oakland and Macomb Counties where clay-heavy soil puts extra pressure on basement walls.

What to look for: Stair-step cracks in block walls, horizontal cracks (the most serious), doors/windows that stick, and uneven floors. Even hairline cracks can indicate movement over time.
2

Elevated Radon Levels

Health Hazard ☢ 1 in 4 MI homes above EPA limit 📈 Oakland County: 30% elevated High Risk

Radon is the #1 cause of lung cancer among non-smokers, and Michigan has some of the highest levels in the country. It's a colorless, odorless gas that seeps up through soil and into basements. You can't detect it without testing — and your neighbor's levels tell you nothing about yours.

What to know: Every home should be tested. Radon levels can vary dramatically even between houses on the same street. Mitigation systems are highly effective and relatively affordable — this is one of the most fixable serious issues we find.
3

Roof Damage & Ice Dams

Exterior / Weather ❄ Peak damage: Jan–Mar High Risk

Michigan winters are hard on roofs. Ice dams form when heat escapes through the attic, melts snow on the roof, and refreezes at the eaves — forcing water under shingles and into your home. Add wind damage, missing shingles, and deteriorated flashing, and you've got the most common exterior issue we flag.

What to look for: Curled, cracked, or missing shingles. Water stains on ceilings or in the attic. Icicles forming at roof edges (a sign of heat loss). Sagging gutters packed with ice.
4

Water Intrusion & Basement Moisture

Structural / Interior 💧 Most common finding Medium Risk

Wet basements are practically a Michigan tradition — but they shouldn't be. Improper grading, failed sump pumps, cracked foundation walls, and clogged drainage all contribute. Left unchecked, moisture leads to mold, structural damage, and a basement you can't use.

What to look for: Efflorescence (white mineral deposits) on basement walls, musty smells, water stains or tide marks, and a sump pump that runs constantly. Check that the ground slopes away from the house on all sides.
5

Outdated Electrical Panels

Safety / Electrical ⚡ ~20% of pre-1990 homes Medium Risk

Southeast Michigan has a lot of homes built in the 1960s–1980s, many with Federal Pacific or Zinsco electrical panels — brands known for breakers that fail to trip during overloads. We also find aluminum wiring, double-tapped breakers, and panels that simply can't handle modern electrical loads.

What to know: If your home has a Federal Pacific, Zinsco, or Pushmatic panel, get it evaluated. Insurance companies are increasingly refusing to cover homes with these panels. An upgrade is one of the smartest safety investments you can make.
6

Plumbing Issues & Frozen Pipes

Plumbing 🧷 250K MI homes damaged yearly Medium Risk

Aging galvanized steel pipes, polybutylene supply lines, and pipes routed through unheated spaces are common findings in Michigan homes. In winter, frozen and burst pipes are one of the most expensive emergency repairs homeowners face. Even a tiny crack can leak 250 gallons per day.

What to look for: Low water pressure, discolored water, visible corrosion on exposed pipes, and any pipes running through exterior walls or uninsulated crawl spaces. Keep your thermostat at 55°F+ even when away in winter.
7

HVAC & Furnace Concerns

Mechanical 🔥 Avg furnace life: 15–20 yrs Medium Risk

Michigan furnaces work harder than almost anywhere in the country — running 5–6 months straight every winter. We regularly find cracked heat exchangers (a carbon monoxide risk), undersized systems, failed ignitors, and units well past their life expectancy. A furnace that's "still running" isn't necessarily safe.

What to know: A cracked heat exchanger can leak carbon monoxide into your home — undetectable without a CO detector or professional inspection. If your furnace is 15+ years old, a pre-purchase inspection should include a close look at the heat exchanger.
8

Mold & Indoor Air Quality

Health / Environmental 🪝 Common in basements & attics Medium Risk

Where there's moisture, mold follows. Michigan basements, bathrooms, and attics are prime territory. We find mold growth hidden behind walls, under flooring, and in attic sheathing where poor ventilation traps condensation. Some mold is cosmetic. Some triggers serious respiratory issues — the only way to know is to test.

What to look for: Musty odors, visible discoloration on walls or ceilings, condensation on windows, and anyone in the household with unexplained allergy symptoms. Professional testing identifies the type and severity.
9

Deteriorating Sewer Lines

Plumbing / Underground 🌊 High risk in pre-1980 homes Varies

Many Southeast Michigan homes built before 1980 have original clay or cast iron sewer lines. After 40–60 years underground, tree root intrusion, bellying, cracks, and offsets are common. A sewer line failure can cost five figures and destroy your yard. A sewer scope video inspection takes 30 minutes and can save you from a nightmare.

What to know: A sewer scope is one of the most valuable add-ons to a standard home inspection. In about 30 minutes, you see the exact condition of the line — cracks, roots, bellies, everything. Highly recommended for any home over 30 years old.
10

Insulation & Energy Efficiency Gaps

Energy / Comfort 🌡 Most common comfort issue Low Risk

Michigan heating costs are no joke. Inadequate attic insulation, uninsulated rim joists, air leaks around windows and doors, and missing vapor barriers are findings we flag in most homes built before 2000. These aren't safety hazards, but they directly affect your comfort and your energy bills — sometimes by hundreds of dollars per year.

What to look for: Drafty rooms, uneven temperatures between floors, ice dams forming on the roof (a sign of attic heat loss), and energy bills that seem too high. A thermal imaging inspection can pinpoint exactly where you're losing heat.
