Part 1 of 3: Understanding and Preventing Foundation Damage
Why Michigan Foundations Face Unique Challenges
Southeast Michigan experiences some of the most severe freeze-thaw cycles in the country. Unlike regions that stay consistently frozen or consistently mild, we cross the freezing threshold multiple times each winter—sometimes 20-40 cycles per season. This constant expansion and contraction creates tremendous pressure on foundations.
At HHI Services, we inspect hundreds of Michigan foundations each year across Oakland, Macomb, Wayne, Livingston, and Washtenaw counties. Foundation issues from freeze-thaw cycles are among the most common—and most expensive—problems we see. The good news? Most are preventable with proper maintenance.
The Science Behind the Damage:
Water in soil freezes and expands (up to 9% volume increase)
Frozen soil pushes against foundation walls with thousands of pounds of pressure
Soil thaws and contracts
This cycle repeats throughout winter
Heavy clay soils (common in our area) retain moisture and expand significantly more than sandy soils
The Real Cost of Foundation Problems
Prevention: $0-500 annually (grading maintenance, gutter cleaning)
Small crack repair: $200-800
Foundation waterproofing: $3,000-15,000
Wall stabilization: $5,000-15,000
Major foundation reconstruction: $10,000-30,000+
A $500 crack repair today can prevent a $15,000 foundation reconstruction tomorrow. Prevention is always cheaper than repair.
Proper Drainage: Your First Line of Defense
Grading Around Your Foundation (MOST IMPORTANT)
The single most important factor in foundation protection is proper grading. Water is the enemy of foundations, and proper grading keeps it away.
The Goal: 6-inch drop over the first 10 feet from your foundation
Ensures water flows away from house, not toward it
Prevents soil saturation near foundation
Reduces freeze-thaw pressure on walls
How to Check Your Grading:
After a heavy rain, walk around your house
Look for pooling water near the foundation
Place a ball on the ground near the house - it should roll away
Check for soil erosion patterns (shows water flow direction)
Inspect basement for water after rains
Common Grading Problems:
Settling: Soil settles over time, creating low spots
Landscaping: Flower beds built up against foundation
Patio/walkway installation: Creates dam that traps water
Downspout discharge: Empties right next to foundation
DIY Fix:
Add soil to create proper slope away from foundation
Use clay-based soil near foundation (doesn't erode easily)
Compact soil in layers (prevents future settling)
Re-check slope annually, especially after landscaping
Cost: $0-500 DIY, $500-2,000 professional regrading
When to Call a Professional:
Large areas need regrading
Severe pooling problems
Hardscaping (patios, walkways) interfering with drainage
You're seeing foundation issues already
Gutters and Downspouts: Critical Protection
Your gutters are your home's primary defense against foundation damage. When they fail, thousands of gallons of water pour next to your foundation instead of being directed away.
Gutter Maintenance
Clean Gutters Twice Yearly Minimum:
Spring (after tree budding)
Fall (after leaves drop)
More often if you have trees overhanging roof
Signs Your Gutters Need Cleaning:
Plants growing in gutters
Water overflowing during rain
Sagging gutters (weight of debris)
Staining on siding below gutters
Water pooling near foundation after rain
Cost: $150-300 professional cleaning, or DIY if comfortable on ladders
Downspout Extensions (CRITICAL)
This is where most homeowners fail. Your downspouts must discharge water at least 6-10 feet away from your foundation.
Check Your Downspouts:
Where does water discharge?
Does it flow away from house or back toward it?
Are extensions attached or do they just sit loose?
Are extensions damaged or missing?
Solutions:
Rigid extensions: PVC or aluminum, permanent, $10-30 per downspout
Flexible extensions: Easy to install, can be moved for mowing, $15-40 per downspout
Buried drainage: Most effective but more expensive, $200-500 per downspout
Pop-up emitters: Underground pipe with pop-up end, clean look, $150-300 per downspout
DIY Cost: $50-200 to extend all downspouts Professional Cost: $300-2,000 for buried drainage system
Michigan-Specific Consideration: Make sure extensions don't create ice dams on walkways in winter. Angle them toward grass or landscaping areas, not toward driveways or sidewalks.
French Drains and Foundation Drainage
For homes with chronic drainage problems, more comprehensive solutions may be needed.
Surface French Drains
What They Are:
Trench filled with gravel and perforated pipe
Intercepts water before it reaches foundation
Directs water away to discharge point
When You Need One:
Water consistently pools near foundation
Grading alone won't solve problem
Uphill slope directs water toward your house
Low spot in yard traps water near house
Cost: $1,000-3,000 depending on length and complexity
Foundation Drain Tile
What It Is:
Perforated pipe at base of foundation (footing level)
Collects water before it enters basement
Directs water to sump pump or daylight drain
Two Types:
Exterior (best): Installed outside foundation, requires excavation
Interior: Inside basement perimeter, less expensive but less effective
When You Need It:
Chronic basement water problems
Water appears on basement floor regularly
Previous flooding events
High water table area

Seasonal Foundation Maintenance Calendar
Spring (March-May)
Critical Time for Foundation Inspection
Spring thaw is when foundation problems appear. The combination of frozen ground thawing, heavy spring rains, and winter damage creates perfect conditions for issues.
Spring Foundation Checklist:
Walk around foundation after spring thaw
Look for new cracks or changes to existing cracks
Check for water pooling near foundation
Inspect grading - look for settling or erosion
Test downspout extensions are in place and working
Check basement for water intrusion or moisture
Look for efflorescence (white powder) on basement walls
Take photos of any cracks for future comparison
Budget: $0 DIY inspection, $400-600 for professional foundation inspection if concerned
Summer (June-August)
Maintenance and Monitoring
Clean gutters after spring pollen/seeds
Monitor basement during heavy summer storms
Maintain landscaping away from foundation
Check sump pump operation monthly
Water foundation during drought (yes, really)
Wait, Water My Foundation? During extreme drought, clay soil shrinks dramatically and can pull away from foundation. A soaker hose run once weekly during drought can prevent this. Keep soil consistently moist, not saturated.
Fall (September-November)
Prepare for Winter
Clean gutters thoroughly after leaves fall
Ensure downspout extensions in place for winter
Check grading - add soil if needed before ground freezes
Seal any minor cracks before winter
Ensure window wells are clean and covered
Check basement for any moisture issues before winter
Budget: $200-500 for fall preparations and crack sealing
Winter (December-February)
Monitor and Prevent Ice Dams
Keep gutters clear of ice (if accessible safely)
Monitor for ice dams (can direct water toward foundation)
Check basement periodically for moisture
Ensure proper snow removal doesn't pile snow against foundation
Warning Signs: When to Call a Professional Immediately
RED FLAGS (Call Today):
Horizontal cracks in basement walls
Stair-step cracks wider than 1/4 inch
Bowing or leaning basement walls
New gaps between walls and ceiling/floor
Doors or windows that suddenly won't close
Water actively entering basement
MONITOR CLOSELY (Schedule Inspection Soon):
Vertical cracks wider than 1/4 inch
Multiple new cracks appearing
Existing cracks that are growing
Water stains on basement walls
Musty odors in basement
Efflorescence (white powder) on walls
PROBABLY OKAY (But Document):
Hairline vertical cracks (under 1/8 inch)
Small corner cracks (stable, not growing)
Minor step cracks in block (under 1/8 inch)
Pro Tip: Take photos of ALL cracks with a ruler for scale. Date the photos. Check quarterly to see if cracks are growing. Growing cracks need professional evaluation.
