HISTORIC & VINTAGE HOME INSPECTIONS.
Vintage architectural charm meets rigorous forensic scrutiny. We specialize in 50+ year old Texas properties: ungrounded cloth wiring, knob-and-tube, pier-and-beam crawlspaces, and cast iron plumbing.
Meet Inspector Mack & The Secured Team
Every inspection is led directly by TREC Professional Master Inspectors using calibrated diagnostic gear. We don't just check cosmetic boxes—we map subgrade foundation movement, scan thermal anomalies through solid sheetrock, and scope subterranean lateral lines to defend your earnest money and equity.

Historic Home Secrets: Crawlspaces, Cloth Wiring & Wood Rot
Inspector Mack explores the unique engineering of 1900s–1960s Texas homes and how to safely purchase vintage character.
"Never buy a vintage Houston Heights bungalow or Galveston Victorian without an inspector physically crawling beneath the house. 90% of historic home structural nightmares are hidden in the crawlspace."
WHAT WE SPECIFICALLY AUDIT & DELIVER
Our forensic checklist exceeds standard minimum requirements. Every component is rigorously evaluated and cataloged with high-resolution imagery and severity tiers:
Pier-and-Beam Foundation & Subfloor Crawlspace
Hands-on crawlspace inspection of brick/concrete piers, wood rot on main carrying girders, subfloor joists, and floor levelling.
Knob-and-Tube, Cloth Wiring & Fuse Box Audit
Identifying obsolete knob-and-tube circuits, deteriorated rubber/cloth insulation, ungrounded outlets, and Federal Pacific panels.
Galvanized Supply Pipes & Cast Iron Drain Channeling
Checking low water volume from rusted galvanized piping, lead service lines, and cast iron drain pipe corrosion.
Historic Wood Siding, Trim & Original Windows
Auditing historic cypress/pine lap siding, window sash weights, pulley ropes, lead glazing putty, and termite damage.
Attic Framing, True-Dimensional Lumber & Ventilation
Inspecting rough-sawn dimensional rafters, missing collar ties, historical fire damage, and attic gable vent airflow.
Retrofit HVAC Ductwork & Space Constraints
Evaluating cramped attic duct routing, undersized return air plenums, and floor furnace abandonments.
Lead Paint & lead dust Material Identification
Screening pre-1978 painted surfaces, lead dust pipe insulation, transite siding, and vinyl composition tiles.
Historic Chimneys, Fireplaces & Flue Liners
Auditing unlined brick chimneys, crumbling mortar joints, missing spark arrestors, and damper operation.
Texas Gulf Coast Environmental Defect Matrix
Southeast Texas structures face unique environmental stressors that generic national inspection checklists routinely overlook. We specialize in identifying these regional failure modes:
Crawlspace Wood Rot & Fungal Decay
High humidity and poor crawlspace ventilation in coastal Texas cause subfloor framing moisture to stay above 20%, fueling wood-destroying fungi.
Knob-and-Tube Splices in Blown Attic Insulation
Homeowners add blown-in fiberglass or cellulose over vintage knob-and-tube wiring that relies on free air circulation to dissipate heat.
Galvanized Water Pipe Mineral Calcification
Decades of mineral deposits accumulate inside galvanized steel water pipes, restricting flow to a trickle when multiple fixtures run.
Advanced Diagnostic Equipment Suite
Human eyes alone miss hidden electrical hotspots, subterranean pipe collapses, and millimeter-level slab deflections. Every Secured Inspections vehicle is equipped with industrial instrumentation:
Remote Crawler Rover & High-Lumen Inspection Lights
Navigates tight, low-clearance crawlspaces to inspect distant piers and sills.
Protimeter Surveymaster Dual-Depth Meter
Measures exact moisture content percentage in historic wood timbers.
RIDGID® SeeSnake 200ft Video Camera
Captures high-definition interior footage of aging cast iron sewer pipes.
Extech Non-Contact Voltage Detector & Load Tester
Tests for open grounds, reversed polarity, and live knob-and-tube circuits.
Actual Field Finding & Financial Impact
Here is an authentic defect documented in our recent inspections, demonstrating how our forensic reports deliver tangible financial leverage:
Crawlspace Center Sill Fungal Rot & Active Knob-and-Tube Wiring
Inspector Mack physically traversed the 18-inch crawlspace and discovered that the main 6x6 heart pine carrying girder was saturated at 28% moisture content, with active fungal decay causing a 2-inch floor sag in the living room. In the attic, live knob-and-tube circuits were buried under modern blown cellulose.
Frequently Asked Questions: Historic Home Inspections
Everything you need to know about this inspection scope, scheduling timeline, and Texas legal protections:
Q1Do you physically go into the crawlspace during historic home inspections?▼
Yes! Whenever safe clearance exists, we physically enter the crawlspace to inspect every pier, shim, and girder. If clearance is restricted, we deploy remote crawler inspection cameras to guarantee complete subfloor visibility.
Q2Will knob-and-tube wiring prevent me from getting homeowners insurance?▼
Yes, many major insurance carriers will deny coverage or charge exorbitant premiums if active knob-and-tube wiring is present. Our inspection tests every circuit so you know exactly which portions have been modernized and which require immediate rewiring.
Q3What is 'cast iron channeling' and why does it matter?▼
Over 40 to 60 years, the acidic water inside cast iron waste pipes eats away at the bottom of the horizontal pipe (channeling), eventually creating a trench where waste drains directly into the soil beneath your home. Our sewer scope identifies this before closing.
Q4Can I remodel or alter a historic home in a designated district?▼
In historic districts like Galveston or Houston Heights, exterior alterations (windows, siding, porch railings) often require a Certificate of Appropriateness from the local historic commission. We advise on historic architectural integrity.
Q5Should I expect a historic home to have a level foundation?▼
No historic home is perfectly level, but there is a big difference between historical settling that has stabilized and active, progressive settlement caused by rotting sills or collapsed piers. Our ZipLevel survey distinguishes between the two.
Q6Do you test for lead-based paint and surface dust in vintage homes?▼
Yes. For pre-1978 properties, we identify common suspect materials—including lead-based paint on friction surfaces and lead dust pipe wrap—and can collect laboratory samples upon request.
