Part 1: Understanding Your Home's Structure

Foundation Types and Their Characteristics

Foundation TypeDescriptionCommon IssuesConcrete SlabSingle layer of concrete directly on the groundCracking, settling, moisture intrusionCrawl SpaceElevated floor with space between ground and structureMoisture, mold, insulation problems, pest intrusionBasementFull or partial underground living spaceWater seepage, wall cracks, humidity issuesPier and BeamStructure supported by piers/postsSettling, wood rot, inadequate support

Critical Structural Components to Monitor

  1. Foundation walls

  2. Load-bearing walls

  3. Support beams and columns

  4. Floor and ceiling joists

  5. Roof trusses/rafters

  6. Footings and piers

Part 2: Regular Self-Inspection Checklist

Exterior Assessment (Quarterly)

  • Foundation perimeter:

    • Look for cracks larger than 1/4 inch

    • Check for uneven settling or sloping

    • Verify proper drainage away from the foundation (minimum 6-inch slope over 10 feet)

  • Walls:

    • Inspect for cracks, especially around windows and doors

    • Look for bulging or leaning sections

    • Check for deteriorated mortar in brick/masonry

  • Roof and Gutters:

    • Ensure gutters and downspouts are clear and directing water away from the foundation

    • Check for damaged or missing shingles

    • Look for sagging areas or unusual dips

Interior Assessment (Quarterly)

  • Floors:

    • Test for level floors using a marble/ball (should not roll)

    • Look for cracks in tile, separation in wood flooring

    • Check for soft or spongy areas when walking

  • Walls and Ceilings:

    • Inspect for new cracks, especially diagonal ones

    • Look for separated crown molding or baseboards

    • Check for doors/windows that stick or don't close properly

  • Basement/Crawl Space:

    • Check for water intrusion or dampness

    • Look for mold or mildew

    • Inspect wooden supports for rot or pest damage

    • Verify proper insulation and vapor barriers

Part 3: Recognizing Warning Signs

Foundation Problems

  • Cracks wider than 1/4 inch in foundation

  • Doors or windows that stick or won't close properly

  • Uneven or sloping floors

  • Gaps between walls and ceiling/floor

  • Stair-step cracks in brick or block walls

  • Separation of porch or steps from the main structure

  • Foundation walls that bow or bulge

Water Damage Issues

  • Water stains on walls, floors, or ceilings

  • Persistent musty odors

  • Visible mold or mildew

  • Dampness in basement after rain

  • Efflorescence (white, powdery substance) on masonry

  • Peeling paint or wallpaper

  • Warped wood or rotting structural components

Roof and Attic Problems

  • Sagging roof lines

  • Damaged or missing shingles

  • Water stains on attic rafters

  • Inadequate ventilation

  • Compressed or wet insulation

  • Daylight visible through roof boards

Part 4: Documentation Methods

Creating a Home Structural History

  • Baseline documentation: Photograph and note current conditions when you move in

  • Regular updates: Document changes at least annually

  • After events: Record conditions after storms, earthquakes, or nearby construction

  • Measurement tracking: Periodically measure crack widths and locations

Effective Documentation Tools

  • Digital photos with date stamps

  • Video walkthroughs with narration

  • Simple sketches with measurements

  • Crack monitoring gauges (inexpensive plastic tools)

  • Digital level app on smartphone

  • Moisture meter readings in problem areas

Part 5: When to Call Professionals

Signs That Require Immediate Professional Attention

  • Sudden cracks appearing or existing ones rapidly widening

  • Doors or windows suddenly not functioning properly

  • Floors developing significant slopes

  • Unusual popping or cracking sounds in the structure

  • Foundation movement after heavy rain

  • Water intrusion that cannot be traced to obvious sources

  • Visible sagging of any structural component

Part 6: How to Prepare for Professional Assessments

Information to Gather

  • Home age and construction type

  • Previous repair history

  • When problems were first noticed

  • Changes in symptoms over time

  • Weather conditions when problems appear/worsen

  • Recent events (construction, storms, drought)

  • Original blueprints or plans, if available

Maximizing the Assessment Visit

  • Clear access to all areas needing inspection

  • Prepare a list of specific concerns and questions

  • Provide any previous inspection reports

  • Be prepared to discuss the home's history

  • Take notes during the assessment

  • Request photos of problems difficult for you to access

  • Ask about monitoring methods for ongoing issues

Part 7: Evaluating Service Providers

Choosing the Right Professional

  • Verify appropriate licensing and insurance

  • Check professional association memberships

  • Verify experience with your specific type of issue

  • Request and contact references for similar projects

  • Review detailed written proposals before deciding

  • Compare assessment methods and recommended solutions

Red Flags When Selecting Contractors

  • Unwillingness to provide references

  • Pressure tactics for immediate decisions

  • Significant differences in diagnoses between providers

  • Generic solutions without specific problem diagnosis

  • Lack of proper licensing or insurance

  • No written warranty or guarantee

  • Requesting large upfront payments

Part 8: Preventative Maintenance

Protecting Your Foundation

  • Maintain consistent soil moisture around foundation

  • Ensure proper grading (6" slope over 10' from house)

  • Keep gutters clean and downspouts extended

  • Consider installing a drainage system in problem areas

  • Place mulch beds around perimeter to maintain moisture

  • Avoid planting large trees close to the foundation

  • Install root barriers for existing trees near the structure

Controlling Moisture

  • Maintain relative humidity between 30-50% inside home

  • Ensure proper attic and crawl space ventilation

  • Use dehumidifiers in basements and other damp areas

  • Inspect and maintain caulking around windows and doors

  • Check plumbing regularly for leaks

  • Consider crawl space encapsulation if persistently damp

Seasonal Maintenance Calendar

SeasonMaintenance TasksSpringClean gutters, check drainage patterns during rain, inspect for winter damageSummerMonitor foundation for drought effects, inspect attic ventilation, check for pest activityFallClean gutters again, inspect roof before winter, check weather sealingWinterMonitor for ice dams, check basement after thaws, ensure proper indoor humidity

Part 9: Planning for Repairs

Understanding the Scope of Work

  • Distinguish between symptom repair and cause correction

  • Recognize that cosmetic fixes may hide underlying issues

  • Understand the difference between stabilization and complete restoration

  • Consider long-term implications of partial repairs

Budgeting for Structural Repairs

  • Minor repairs (crack sealing, small masonry work): $500-2,500

  • Moderate repairs (waterproofing, partial foundation work): $2,500-10,000

  • Major structural repairs (extensive foundation work, structural reinforcement): $10,000-30,000+

  • Complete foundation replacement: $30,000-100,000+

Financial Considerations

  • Check insurance coverage (most policies exclude foundation issues)

  • Explore home equity financing options

  • Consider phased repair approaches when appropriate

  • Obtain multiple quotes for significant work
