About
Sage Co. was founded by Jake Rangel, a Marine Corps veteran who knows what it feels like when a nervous system won't stand down. After years of optimizing every input he could reach and still not finding rest, the shift came on a Heroes & Horses pack trip in the Montana backcountry — on a mountainside, picking sage, the idea for the company became clear.
Sage Co. answers the question Jake had to answer for himself: what is the home itself quietly doing to the body trying to heal? Today, Sage Co. designs and builds homes engineered for human health in the New Braunfels–San Antonio–Hill Country corridor. Every project is delivered against the Sage Standard — a 9-domain framework spanning air, moisture & mold, materials, water, light, sound, and the building envelope itself — engineered specifically for the hot-humid Texas climate, where most healthy-home playbooks written elsewhere quietly fail. Jake is IBE-trained, with building biology certification in progress.
Homes Built for Human Health.
Why Choose Us
We're the builder for the client other builders can't serve.
Sage Co. is a general contracting firm that builds for human health. Every remodel and ground-up build is engineered against a nine-domain health standard — envelope, air, moisture, materials, water, light, thermal comfort, acoustics, and EMF — and verified against hard benchmarks when the work is done.
We build for this climate. Hot-humid Central Texas punishes assumptions imported from other regions. Our assemblies, mechanical strategies, and humidity control are engineered for Zone 2A specifically.
We grade our evidence. Established, Emerging, or Unverified — clients hear plainly which is which. No fear-based selling, no claims the science doesn't support. It's why health-conscious clients trust us and design professionals refer us.
Marine Corps Discipline, Montana Origin
Jake's path through Heroes & Horses — the 41-day wilderness program for combat veterans on Montana's Double-H Ranch — is the company's founding story. The work carries the same discipline: the air, the materials, the moisture, the light. Read the house, fix the house.
Construction Lineage In-House
Principal Raul Rangel leads execution with decades of construction experience and luxury-residential project volume. Project Manager Bryce Fry brings Texas A&M training and years of property inspection background. The firm builds what it measures.
Evidence-Based, Not Apocalyptic
Site references EPA, WHO, Allen et al. 2016 (cognition and CO₂/VOCs), Satish et al. 2012, and current ASHRAE guidance. The register is measured: 'your home should heal you, not harm you' — not 'your home is killing you.'
