Home inspection checklist in Dallas
Older homes across established Dallas neighborhoods—like East Dallas, Lakewood, Oak Cliff, and the Park Cities—possess unmatched character, mature tree canopies, and architectural details. However, homes built before 1980 also come with unique structural, plumbing, and electrical age risks driven by North Texas weather and soil.
Use this targeted checklist when walking through an older Dallas property alongside a licensed Texas Real Estate Commission (TREC) home inspector.
1. Foundation & Soil Movement (Black Prairie Clay)
Dallas rests on expansive clay soil that swells during spring rains and shrinks during intense summer heat. This continuous cycle puts immense pressure on foundations.
For Pier-and-Beam Foundations (Common in Pre-1960s Homes)
Crawlspace Access: Verify the inspector climbs under the floor to check piers, wood beams, and subflooring.
Pier & Shim Condition: Check for tilting concrete piers, rotting wood beams, or temporary wooden shims that indicate improper leveling.
Drainage & Standing Water: Look for signs of pooled water or damp soil in the crawlspace, which accelerates wood decay and soil movement.
Subfloor & Levelness: Test floors inside for noticeable slopes, "spongy" spots, or gaps between floorboards and baseboards.
For Concrete Slab Foundations (Common in Post-1950s Homes)
Differential Settlement Signs: Inspect walls for diagonal interior drywall cracks near door frames and exterior brick veneer zigzag (stair-step) cracks.
Foundation Level Survey: Confirm your inspector performs a elevation survey to measure floor levelness across the home.
Door & Window Alignment: Check if exterior doors stick, fail to latch, or show visible gaps in framing.
2. Plumbing & Underground Drainage
Plumbing materials in mid-century and historic homes have finite lifespans. Soil shifting frequently cracks or shears rigid pipes underground.
Cast Iron Drain Lines: Homes built before 1975 likely have original cast iron sewer lines underneath the slab or crawlspace. Cast iron corrodes from the inside out after 50 years. Order a hydrostatic test and sewer camera scope inspection ($500-$800).
Galvanized Steel Water Supply Pipes: Check for original galvanized steel pipes. Over decades, rust builds inside them, causing low water pressure and discolored water.
Slab Leaks: Look for warm spots on floors, unexplainable damp carpet, or a water meter that spins when all indoor taps are off.
Tree Root Intrusion: Dallas's mature oak and pecan trees frequently invade older clay or cast iron sewer pipes seeking moisture.
3. Electrical Wiring & Safety Systems
Electrical standards have evolved significantly. Outdated wiring poses genuine fire hazards and may prevent you from securing standard home insurance.
Knob-and-Tube Wiring (Pre-1950s): Check if ungrounded knob-and-tube wiring remains active in the attic or wall cavities. Most modern insurance companies will not cover homes with active knob-and-tube.
Aluminum Wiring (1965–1973): Check for single-strand aluminum branch circuit wiring, which expands and contracts at connections, creating fire risks unless retrofitted with proper connectors.
Panel Brand & Capacity: Ensure the main electrical service panel is at least 150–200 amps. Watch out for obsolete panels like Federal Pacific Electric (FPE) Stab-Lok or Zinsco, which have high breaker failure rates.
Grounding & Outlets: Check for two-prong ungrounded outlets. Ensure GFCI protection is present near sinks, bathrooms, kitchen countertops, and exterior outlets.
4. Roof, Attic & Severe Weather Resistance
North Texas hail, high winds, and heat stress exterior home envelopes quickly.
Roof Age & Layers: Check shingle age and ensure previous owners didn't lay new shingles over old wood shake or old shingle layers.
Roof Flashing: Check flashing around chimneys, dormers, and valleys for rust or improper sealing.
Attic Ventilation & Insulation: Older homes often lack adequate soffit/ridge venting or insulation depth, driving up summer electric bills.
Gutters & Downspouts: Verify that downspout extensions discharge water at least 3–5 feet away from the foundation to prevent soil erosion and expansion.
5. Environmental & Historic Overlay Considerations
Lead-Based Paint (Pre-1978 Homes): Inspect for peeling or chipping paint on window sills, doors, and exterior trim.
Asbestos Materials: Be mindful of original vinyl floor tiles (often 9x9 size), acoustic popcorn ceilings, or duct insulation from mid-century builds.
Historic/Conservation District Rules: If purchasing in neighborhoods like Junius Heights, M Streets, or Winnetka Heights, confirm if property modifications require approval from a local Historic Landmark Commission or Conservation District board.
