Alamo Heights homeowners take real pride in their historic bungalows, Spanish revival estates, and tree lined streets along Broadway and Austin Highway, and On-Site Home Services helps keep that pride on full display. San Antonio's long, humid summers push mold, algae, and hard water spots onto stone facades, wood siding, and limestone walls faster than most owners expect, while our mild winters mean yard work, gutters, and outdoor lighting projects can happen nearly year round. Seth Estrada and his local crew know Alamo Heights inside and out, from the mature oak canopies that drop heavy debris each fall to the caliche soil that makes proper drainage and hardscaping so important. Whether it is a historic home near Olmos Basin or a newer build near the Quarry, our team shows up on time, treats every property with care, and backs every job with a free estimate and twenty percent off your first service.
