Service specs · Castle Hills
Built for Castle Hills owners.
Castle Hills sits inside Loop 410 with tree-lined streets and historic homes. Lots are smaller than the outer suburbs but owners invest heavily in their vehicles. We service driveways throughout Castle Hills and coordinate aircraft details at SAT and Stinson hangars five to fifteen minutes away.
Owner profile. Castle Hills is a tiny wealthy enclave inside San Antonio's loop. Lots are modest in size but owners trend high-end: sport boats trailered to Canyon Lake, owner-flown Cirrus and Citation aircraft at SAT, and luxury smaller-format RVs.
Light twins are a niche corner of aviation. Owners who fly twins typically do so because they need the redundancy — over water, at night, IFR in real weather. The fleet is older than the single-engine piston fleet (Barons and Cessna 310s built in the 1970s still fill ramps), and twins come in two flavors: the owner who loves it and keeps it immaculate, and the owner who can barely afford the maintenance and lets the paint fade. We see both. A Baron in good cosmetic shape takes 5-6 hours; a neglected Cessna 421 with belly stains from both engines and a faded de-ice boot can run 8-10 hours. We always quote after the walk-around.

Light twins protocol — Castle Hills edition.
Walk-around: confirm scope, identify any sensitive items (taped sensors, fresh paint, repair patches), photograph any pre-existing damage so there's no question what was there.
Mask pitot tubes, static ports, AOA vanes, antennas, and total air-temperature probes on the airframe.
Pneumatic de-ice boots (if equipped): special boot wash with pH-neutral cleaner, then Age Master rubber conditioner by hand.
Belly degrease — two engines means two exhaust trails. Aviation-grade exhaust-stain remover, hand-worked with microfiber, never power-washed.
Leading edges get bug-strike remover applied by hand, dwelled, and wiped — both wings.
Full exterior wet wash with Aero Cosmetics aviation soap on ramps with drains; dry wash with Wash Wax All in hangars.
Hand-polish each engine cowling separately (nacelle fairings included).
Polish painted control surfaces hand-only — no rotary near rivet lines.
Acrylic windshield + side windows with Plexus or PlastX and a fresh microfiber.
Cabin: leather conditioning, headliner spot-clean, side-panel wipe, screen-safe avionics cleaning.
N-number and registration touch-up; wing-walk strips inspected.
Final walk with owner — all masking removed.
What's included.
What owners always ask.
Yes — Stinson Municipal (SSF, in town) is part of our regular service rotation. We coordinate hangar or ramp access with the FBO or owner ahead of every appointment. GA ramp loaded with owner-flown singles, twins, and turboprops. Multiple FBOs and tenant hangars.
Yes — boots get a pH-neutral wash followed by Age Master rubber conditioner applied by hand. Boots that are starting to crack or check we'll flag so you can plan a replacement. We don't pretend they're fine if they aren't.
Yes — twin-engine bellies with years of exhaust stain need a real degrease. We use aviation-grade exhaust stain remover, hand-worked with microfiber, dwell time as needed, multi-pass on heavy buildup. We don't power-wash an aircraft belly.
Only with screen-safe microfiber and approved cleaner. We follow Garmin (G500 / G1000 / GTN / G3X Touch), Aspen Avionics, Avidyne, and Collins guidance. If you have a specific OEM cleaner, bring it.
Stinson (SSF), San Antonio International (SAT) GA ramp, Boerne Stage (5C1), New Braunfels Regional (BAZ), Hondo (HDO), Kerrville (ERV), Fredericksburg (T82), and most smaller strips. We coordinate ramp or hangar access with you ahead of the appointment.
Yes — aviation liability rider for ground operations. COI available to your FBO or hangar landlord on request.
A Baron 58 in good shape runs 5-6 hours. A Cessna 421 with full belly degrease, boot service, and cabin runs 7-8 hours. Older 340s or Aztecs with neglected paint and chronic exhaust stains can push to 8-10 hours.
A standard exterior wash, polish, and cabin on a Baron or Seneca starts at $700. A Cessna 421 with full belly degrease, de-ice boot service, and cabin runs $1,000-1,200. Heavy restoration or pre-buy details can run $1,500.
