The Visual Inspection: Reading Your Foundation’s Story

Every professional foundation diagnosis begins with a thorough visual inspection, both inside and outside your home. This initial assessment provides crucial clues about foundation performance without requiring specialized equipment. Experienced foundation specialists can identify patterns that indicate specific types of foundation movement.

Inside your home, inspectors examine walls, ceilings, and floors throughout every room. Diagonal cracks extending from corners of doors and windows often indicate differential settlement, where one part of the foundation has sunk more than another. Doors and windows that suddenly stick or won’t close properly indicate frame distortion caused by foundation shifting. Inspectors test each opening, noting gaps between frames and walls. Floors receive scrutiny for visible slopes, dips, or bounce, with inspectors walking through each room to feel for unevenness.

Outside, inspectors examine the foundation perimeter for visible cracks in concrete slabs or foundation walls. Stair-step cracks in brick veneer signal significant foundation movement. They assess soil conditions around the foundation, noting whether soil has settled away from the foundation or whether excessive moisture accumulates near the home. Drainage patterns matter tremendously, as improper water management is North Texas’s leading cause of foundation problems. Inspectors check gutters, downspouts, grading, and landscaping features that might direct water toward rather than away from the foundation.

Precision Measurement: Elevation Surveys Reveal the Truth

While visual inspection provides valuable clues, precision measurement tools quantify exactly how much your foundation has moved and where movement has occurred. Professional foundation inspectors use instruments called manometers or water levels to measure relative elevation differences throughout your home with remarkable precision. These tools work on the principle that water seeks the same level across a connected system.

The inspector places a base unit in one location and moves a measuring probe to various points throughout your home, recording elevation readings at each spot. By taking measurements at multiple locations in every room, the inspector creates a comprehensive elevation map showing high points, low points, and slope gradients. This data reveals whether your foundation has experienced uniform settlement (the entire foundation sinking evenly) or differential settlement (some areas sinking more than others). In North Texas’s expansive clay soil, differential settlement is common and requires targeted repair.

Some inspectors use laser levels or advanced digital measuring systems like the ZIPLEVEL to assess floor elevations. These tools provide similar information through different technology, with the advantage of quickly measuring elevations throughout large homes and generating detailed contour maps showing exactly where and how much the foundation has moved.

From Measurements to Accurate Diagnosis

Collecting measurements is only part of the diagnostic process. Experienced foundation professionals must interpret what the data reveals about your foundation’s condition and the forces causing problems. When analyzing elevation survey results, inspectors look for specific patterns that indicate different types of foundation issues. Corner dips often result from moisture loss in soil beneath those areas, commonly caused by nearby tree roots. Center elevation with perimeter settlement suggests the edges of the foundation are sinking while the middle remains supported, typical of homes where drainage concentrates water at the foundation perimeter.

Not every foundation showing some movement requires repair. Foundations naturally settle slightly during their first few years, and minor elevation variations within industry tolerance (typically 1 inch or less of differential movement) may not warrant intervention. This is where Dodson Foundation Repair’s commitment to honesty makes a crucial difference. We evaluate whether addressing the underlying cause (improving drainage, managing soil moisture, removing problematic trees) might prevent further movement without expensive foundation work.
