"From the historic homes lining Seguin's tree-shaded streets to the new construction and country properties along the Guadalupe River, Daniel Windler and ATD Property Inspections bring a Master Plumber's eye and 35 years in the trades to every property in Guadalupe County."
Seguin is one of the oldest towns in Texas — founded in 1838 and serving as the seat of Guadalupe County, set along the banks of the Guadalupe River just east of San Antonio. Known for its towering pecan trees, its beautifully preserved historic downtown, and landmarks like the Texas Lutheran University campus and Max Starcke Park, Seguin pairs a deep stock of older and historic homes with a steady wave of newer subdivisions and rural acreage properties. ATD Property Inspections — owned and operated by Daniel Windler, a TREC Licensed Professional Inspector (#21665) and licensed Master Plumber — serves home buyers, sellers, and investors throughout Seguin and the surrounding Guadalupe County communities.
Daniel brings 35 years of hands-on experience as a licensed Master Plumber and construction professional to every Seguin inspection. He's worked on properties of every era — from century-old homes in Seguin's historic neighborhoods to newer construction and country acreage on the city's edges. A U.S. Marine veteran, Daniel handles every inspection personally and treats each home as if he were inspecting it for his own family, explaining his findings in plain language with no unnecessary alarm and no sales pressure.
Seguin's deep stock of older homes brings inspection challenges a local expert knows to watch for. Historic and older Seguin homes often still carry aging cast-iron drain lines, galvanized supply lines, and dated electrical and HVAC systems nearing the end of their service life — exactly the hidden problems Daniel's plumbing background is built to find. Many rural Guadalupe County properties also run on private wells and septic systems, which he's certified to inspect, while the region's expansive clay soils and Texas heat stress foundations, supply lines, and roofs. His specialty inspections — sewer camera video, hydrostatic testing, WDI/termite, septic and well/water, and pool and spa — cover the systems a standard inspection often can't reach, which matters most in a town with housing this old.
That's exactly why Seguin-area homeowners choose ATD Property Inspections.
