"Mid-century ranch homes on big, tree-shaded lots inside Loop 410: Daniel Windler brings a Master Plumber's eye and 35 years in the trades to every Castle Hills inspection."
Castle Hills is a small, independent city on San Antonio's north side, just inside Loop 410 near NW Military Highway. It grew up in the 1950s and 1960s as a neighborhood of spacious lots, and it has kept that character: wide streets, big yards, mature oaks, and long, low ranch-style homes, many with backyard pools. Residents enjoy a quiet, established setting while staying minutes from the airport, the Medical Center, and North Star Mall. Original owners and longtime families are gradually giving way to new buyers who are updating, expanding, or rebuilding. ATD Property Inspections, owned and operated by Daniel Windler, a TREC Licensed Professional Inspector (#21665) and licensed Master Plumber, serves buyers, sellers, and homeowners throughout Castle Hills.
A home built 60 or 70 years ago can look solid and still be running on original systems. Castle Hills ranch homes often have cast-iron drain lines beneath the slab, long sewer runs across large lots, older water heaters and supply piping, and electrical panels that have seen decades of add-ons. Daniel's 35 years as a licensed Master Plumber and construction professional mean he knows what these systems look like as they age, and he can camera the sewer line or pressure-test the drains under the slab in the same visit.
Large lots and big trees bring their own set of concerns. Oak roots are drawn to older sewer lines, and heavy trees near the house can pull moisture unevenly from the clay soil, contributing to foundation movement, cracked brick, and doors that stick. Backyard pools built decades ago may have aging equipment and plumbing that deserve a certified look. Daniel checks the home and the property around it and explains every finding in plain language, with no unnecessary alarm and no sales pressure.

Answers to the most common questions Castle Hills homeowners ask before scheduling a property inspection.
The original systems. Daniel pays close attention to under-slab drain lines, supply piping, the water heater, and the electrical panel, along with the roof, attic, and foundation, since these are the items most likely to be near the end of their life.
For most homes here, it's a smart add-on. Long sewer runs across large lots, older pipe materials, and mature oak roots make root intrusion and pipe damage common. A camera inspection shows the line's real condition before you buy.
