Real or Fake? Spotting Foundation Damage on Home Listing Photos - Image 1 Scrolling through online home listings can be an exciting journey, filled with dreams of open floor plans and gourmet kitchens. But beneath the freshly painted walls and staged furniture, potential problems can lurk, and your home's foundation is one of the most critical areas to scrutinize. Savvy homebuyers, and even current homeowners keeping an eye on their neighborhood, can learn to spot potential foundation issues just by carefully examining those listing photos. While nothing replaces a thorough professional inspection, knowing what to look for in those seemingly innocent pictures can save you from a world of headaches (and hefty repair bills) down the road.

Think of it as becoming a foundation detective. You're looking for subtle clues, inconsistencies, and anything that deviates from the perfectly square and level ideal. Here’s your guide to spotting potential foundation damage in home listing photos:

Cracks Tell Tales

Pay close attention to foundation walls visible in basement or exterior shots. Look for cracks – not just any cracks, but their pattern and size.

Horizontal Cracks: These can be a sign of significant pressure from the soil outside. In our region with its freeze-thaw cycles and clay-heavy soils, horizontal cracks, especially if they appear bowed or bulging, should raise a red flag.
Vertical Cracks: While some hairline vertical cracks can be normal due to settling, wider vertical cracks or those that are offset (one side higher than the other) could indicate more significant movement.
Diagonal Cracks: Cracks running diagonally, especially near corners of windows or doors, can also suggest foundation settlement or shifting.
Stair-Step Cracks: These cracks follow the mortar joints in brick or block foundations and are often a sign of differential settlement – one part of the foundation is sinking more than another.

Don't dismiss even seemingly small cracks in listing photos. Zoom in if possible. Note their location and if there are multiple cracks clustered together.

Unevenness is a Red Flag

Look for anything that appears unlevel or out of square.

Sloping Floors: While hard to discern perfectly from a photo, look for cues like furniture that seems to lean or doors that appear crooked within their frames. Sometimes a wide-angle lens can exaggerate this, but if something looks noticeably off, it's worth investigating further.
Gaps Around Doors and Windows: Check photos of both interior and exterior doors and windows. Are there noticeable gaps between the frame and the wall? This could indicate foundation movement that has shifted the house's structure.
Misaligned Walls: Look down the length of walls in photos. Do they appear straight, or do they have a noticeable bow or bulge? This is often easier to spot in unfinished basements.

Water Woes Leave Visual Clues

Water in a basement is a major indicator of potential foundation problems. Look for:

Water Stains: Discolored areas on basement walls or floors, especially near the foundation, could indicate past water intrusion. These stains might appear as dark marks, mineral deposits (white powdery residue), or even mold growth (dark, splotchy areas).
Efflorescence: This is the white, powdery substance you sometimes see on concrete or brick walls. It's caused by water seeping through the foundation and leaving behind salt deposits as it evaporates, a clear sign of moisture issues.
Rust or Rot: Look around the bases of support columns or wooden beams in basement photos. Rust on metal or rot on wood near the foundation suggests prolonged exposure to moisture.
Sump Pump Presence (and Absence): While a sump pump indicates the potential for water issues, its absence in a region prone to groundwater problems could also be a concern. Look for the telltale lid or discharge pipe.

Exterior Clues Matter Too

Don't just focus on the basement. Exterior photos can also offer insights:

Uneven Grading: Examine how the ground slopes around the house. Ideally, it should slope away from the foundation to direct water away. Look for areas where water might pool against the foundation.
Foundation Exposure: Is more of the foundation visible on one side of the house than the other? This could indicate settlement.
Cracks in Exterior Walls or Chimney: Cracks that extend up into the exterior walls or chimney can be a sign of significant foundation movement.

Be a Skeptic, Not a Cynic

Remember that staging can sometimes hide flaws. Fresh paint might cover water stains, and carefully placed rugs could conceal uneven floors. Use the photos as a starting point for your investigation. If you spot any of these red flags, it’s crucial to schedule a thorough professional home inspection, including a detailed foundation assessment, before making any decisions.
