Some of the most important structural components in your home sit in a space you have probably never seen. The area beneath your floors houses your joists, support beams, plumbing runs, and much of what keeps everything level, yet it remains out of sight for years at a time. When trouble starts down there, whether it is a slow plumbing leak or the early signs of wood rot, the damage often spreads long before anyone notices. A thorough crawl space inspection from PTJ Home Defenders brings those hidden conditions to light so you can address them while they are still small.
PTJ Home Defenders is a home and commercial inspection company based in McKinney, Texas, serving homeowners and buyers across the North Dallas region. The company specializes in robotic crawl space inspection, using a Wombat crawler to reach areas that are too low, too tight, or too unsafe for a person to enter. Led by owner Pat Evers, a Certified Master Thermographer, the team brings ASHI certification, a licensed WDI technician on staff, and years of field experience to document exactly what is happening under your floors.
Most homeowners never crawl beneath their house, and few would want to. That distance from the space is the whole problem. Moisture buildup, mold growth, sagging joists, cracked piers, and standing water can develop quietly, and because nobody is looking, a minor issue turns into a structural headache. Some crawl spaces are so shallow, with as little as eight inches of clearance in spots, that a person simply cannot fit inside to check them at all.
North Texas gives crawl spaces a hard time. The expansive clay soil under McKinney and the neighboring cities swells when wet and shrinks when dry, and that constant movement pushes on foundation piers and beams season after season. Add humid summers, poor drainage after heavy storms, and vapor barriers installed years ago that have since torn or shifted, and you have the perfect setting for wood rot, rust, and pest activity. Plumbing and HVAC lines running through the space only create more places for leaks to hide.
This is where the Wombat robotic crawler earns its keep. Our technician sends the robot into the crawl space rather than forcing a person to work in cramped, filthy, or hazardous conditions. Fitted with high-definition cameras and bright LED lighting, it travels the full area and records detailed photos and video along the way. We inspect the floor joists, support beams, and subfloor for damage; check the foundation walls and piers for movement or settlement; and closely inspect moisture levels, the vapor barrier, plumbing lines, ductwork, and any signs of rodents or insects.
When the robot comes back out, we sit down with you and go through the footage together, pointing out what looks healthy and what needs attention. You get a clear picture of the condition below your floors without ever getting your hands dirty, and you can plan repairs or maintenance based on what the cameras actually found. Catching a leak or a shifting pier early tends to cost a fraction of what a full structural repair runs later, which protects both your home and your budget.
A camera on wheels changes what an inspector can safely reach and document. Here is what that means for you as a homeowner.
The Wombat crawler slips into gaps as narrow as eight inches, so the low corners and pinched sections that a person would have to skip get inspected right along with everything else. Areas once written off as unreachable finally get a proper look.
Every finding comes with footage you can see for yourself. Rather than taking a written note at face value, you watch the actual condition of your joists, piers, and vapor barrier on screen and keep that record for future reference or resale.
Water problems reveal themselves long before floors upstairs start to feel soft. Spotting damp framing, a failing vapor barrier, or standing water during the inspection lets you address the source before mold spreads or beams weaken.
No one has to squeeze through insulation, spider webs, or soggy soil to get answers. The robot handles the dirty work, which removes the health and safety risks that come with sending a technician into an unknown space.
Footage only helps if someone knows how to read it. Pat Evers and the PTJ Home Defenders team pair ASHI certification with Master Thermographer training on every review, translating what the camera sees into plain guidance you can act on.
Choosing an inspector comes down to who you can rely on to tell you the truth about your home. Here is what sets our team apart.
The company holds ASHI certification through Lone Star ASHI, employs a licensed WDI technician for wood-destroying insect concerns, and carries certifications for pools and septic systems. That range means one visit can cover far more than just the crawl space.
Owner Pat Evers is a Level 2 Certified Master Thermographer, so hidden moisture and temperature clues that others miss are often caught here. That background pairs naturally with crawl space work, where damp spots often appear well before they become visible damage.
You will hear what your home actually needs, not anything invented to pad an invoice. Findings get explained in language that makes sense, and the decision about how to move forward stays with you.
Serving McKinney, Allen, Frisco, Plano, and the wider Dallas area means we understand how regional clay soil and storm patterns wear on a crawl space over time. That familiarity shapes what we look for during every visit.
Military members, veterans, and first responders receive a discount as our way of saying thank you. Paying is easy as well, with cash, checks, credit cards, Zelle, and Venmo all accepted.

Shifting soil is a fact of life around Dallas. A foundation inspection evaluates the performance of piers, beams, and the slab to catch movement and cracking before they require major structural repairs.
For a focused review of your home’s footing, a foundation check zeroes in on the signs of settlement and movement, giving you a quick read on whether a deeper evaluation is warranted.
Temperature tells a story the naked eye misses. Infrared thermography inspections map heat patterns across walls and ceilings to locate moisture intrusion, electrical hot spots, and hidden air leaks.
Working room by room with the same infrared technology, home thermal imaging pinpoints trouble spots in your living space, from drafty windows to damp drywall you would never catch otherwise.

The clay-heavy soil throughout McKinney and the surrounding suburbs expands and contracts with every wet and dry spell, which stresses foundation piers and framing. Regular crawl space inspections catch the resulting cracks, gaps, and moisture problems before they reach the floors above.
The crawler sits low to the ground and moves into spaces with as little as eight inches of clearance. Homes across Allen, Frisco, and Plano often have shallow or obstructed crawl spaces, and the robot inspects those tight areas that would otherwise go unchecked.
It certainly will. Buyers throughout the Dallas region use our crawl space findings to understand a property’s true condition and to negotiate repairs. Seeing the footage before closing removes a great deal of guesswork from a major purchase.
Moisture intrusion, torn vapor barriers, rusted supports, plumbing leaks, and pest activity are most common, along with signs of foundation movement tied to local soil conditions. Older Frisco and Prosper homes with dated drainage setups tend to reveal water issues in particular.
