WE PRACTICE WHAT WE PREACH:
NON TOXIC HOME CONSTRUCTION

From better building practices to safer material choices, every decision we make as your builder contributes to safer, cleaner, and healthier living for you and your family.

Why do we do it? Jen's home was making her sick years ago. And finding a place to live that didn't have chemicals and mold was not possible. So she set out to create the world's first healthy home.

How do we accomplish this? JS2 co-founders, Jen & Rusty Stout, are the creators of the healthy home building movement. We're literally writing the book on how to build homes using healthy home building construction best practices (no really, we wrote a book about it!)

Our non-toxic homes are free from chemicals like formaldehyde, petroleum solvents and mold. We use nothing that emits harmful EMF frequencies. And our focus is on natural materials and beautiful design, for spaces that are as restful and peaceful as they are rejuvenating and wholesome.

HOW WE APPROACH HEALTHY HOME CONSTRUCTION

What Non-Toxic Home Builders Actually Do Differently — From First Call to Move-In

Most builders will tell you they care about quality. Healthy home builders have to prove it at every phase — because the decisions that determine whether a home is truly non-toxic are made long before the first nail is driven, and they're rarely visible once the walls are closed up. A home can look finished and still be quietly working against the people living in it, which is why healthy construction isn't something you can inspect for after the fact. Here's how our healthy home construction process works from start to finish.

Health + Lifestyle Discovery

Before we talk floor plans or finishes, we talk about you. Do you have chemical sensitivities, allergies, or asthma? Are there children or aging parents in the household? Have you lived in a home that made you feel worse — headaches, fatigue, respiratory issues — without being able to pinpoint why? These questions aren't intake form checkboxes for us. They directly shape the material specifications, ventilation strategy, and design priorities for your home, long before we get to anything you'd recognize as a finish selection.

A household with severe fragrance sensitivities requires a different level of material vetting than a household primarily concerned with formaldehyde, and we need to know the difference before we start specifying anything. We've found that clients rarely arrive with a complete picture of their own sensitivities — it often takes a conversation to surface patterns they'd never connected to their home before, and that conversation is where genuinely healthy home construction actually begins.

Site Evaluation Through a Healthy Building Lens

The site itself has health implications that most builders never consider. Orientation affects natural light and passive ventilation opportunities. Prevailing winds matter when neighboring land use could introduce airborne contaminants. Soil conditions in Central Texas can harbor naturally occurring mold spores and radon. We evaluate your site not just for topography, utilities, and access — but for the environmental factors that will affect what happens inside the walls of your home for decades to come.

This is a step most builders skip entirely, and it's one we consider foundational to genuine healthy building. A site evaluation that only looks at buildability and ignores what's blowing across the property, what's in the soil, or how air will actually move through a finished home is an incomplete evaluation — and the gaps in it tend to show up later as problems nobody can quite trace back to their source.

Healthy Material Specification

This is where healthy home construction services diverge most dramatically from standard building practice, and where our depth of experience is most valuable. We have spent years vetting materials across every category of residential construction — and the list of what we won't use is as important as what we will.

For every home we build, we develop a full material specification covering framing lumber, sheathing, insulation, housewrap, roofing, drywall, adhesives, sealants, flooring, cabinetry, countertops, tile, paint, and finish hardware. Each category is evaluated for VOC content, formaldehyde emissions, heavy metal presence, off-gassing potential, and EMF considerations. We don't rely on manufacturer labels or “low-VOC” marketing claims — we do the research ourselves, which is why we wrote the book on it. Literally.

Building Envelope + Ventilation Design

A healthy home isn't just about what materials go inside it — it's about how air moves through it. A tight, well-insulated building envelope is the foundation of healthy construction: it keeps conditioned air in, uncontrolled infiltration out, and gives you command over what air your family breathes. But a tight envelope without a deliberate ventilation strategy is its own problem. We design mechanical ventilation systems — ERVs, HRVs, and properly sized HVAC with quality filtration — that provide consistent fresh air exchange without introducing outdoor allergens, humidity, or pollutants uncontrolled.

In Central Texas, this matters acutely. Mountain Cedar season, oak pollen, and high outdoor humidity during shoulder seasons mean the air outside is frequently the last thing you want circulating freely through your home. A well-designed healthy home manages this systematically, not as an afterthought bolted onto a standard HVAC plan.

Construction Quality Control

Non-toxic home construction requires active oversight during the build — not just a good spec sheet sitting in a binder somewhere. Subcontractors working within our projects are briefed on our material standards and substitution policies. If a specified product is backordered and a sub wants to swap in an alternative, that substitution goes through us before it goes in the wall, not after.

Moisture management during construction is treated with the same rigor as the finished product — wood framing that gets rained on and isn't properly dried before being closed in creates the conditions for future mold problems regardless of how good the finishes are. We catch these issues at the framing stage because that's the only point where they're still cheap and easy to fix.

Pre-Occupancy Verification + Handoff

Before you move in, we conduct a pre-occupancy review of all systems — ventilation performance, HVAC commissioning, filtration, and a final walkthrough of materials and finishes. We provide complete documentation of every material used in your home: what it is, where it was sourced, and why it was selected. For clients with serious sensitivities, this record is invaluable — both for peace of mind at move-in and for reference if health questions arise years later. We remain available after handoff, because healthy home construction isn't something we consider finished the day you get the keys.

FAQS ABOUT HEALTHY HOME CONSTRUCTION IN CENTRAL TEXAS

What makes a home a “healthy home”?

A healthy home is designed to reduce everyday exposures that can quietly affect how you feel—air quality, humidity, allergens, and the chemical load that comes from common building materials. In practice, that means selecting low-toxicity products, minimizing materials that can off-gas, and detailing the home so fresh air is managed intentionally rather than entering through random leaks. Comfort is part of health, too: a home that maintains steady temperatures and balanced humidity tends to feel better day-to-day and can be easier on people with sensitivities. In Central Texas, “healthy” also includes a moisture and ventilation strategy because heat and humidity can amplify musty odors, allergens, and indoor pollutants. We look at the whole system—air sealing, ventilation, filtration, and HVAC sizing—so airflow is consistent and humidity stays in a healthy range. At JS2 Partners, healthy home construction blends smart building science with non-toxic material selections so your home supports wellness, sleep quality, and long-term comfort.

Why should I choose non toxic home builders over traditional builders?

Non toxic home builders focus on reducing the hidden sources of indoor pollution that many homeowners don’t realize they’re living with—VOCs, formaldehyde, harsh sealants, and finishes that can irritate eyes, skin, and lungs. Traditional building methods often use industry-standard products that are convenient and widely available, but those choices may not prioritize indoor air quality. A non-toxic approach brings that priority forward from the start, so material selections, adhesives, paints, sealants, cabinetry, and flooring are chosen with your health in mind. That’s especially valuable for households with children, allergy or asthma concerns, or anyone who’s sensitive to odors and chemicals. The result isn’t just “safer”—it often feels cleaner, less stuffy, and more comfortable because ventilation and filtration are planned with intention. When you work with a builder who understands non toxic home construction, you’re less likely to make last-minute substitutions that compromise air quality, and more likely to end up with a home that truly aligns with your wellness goals.

Can existing homes be remodeled into healthy homes?

Yes—healthy home principles translate extremely well to remodeling, and you can often make meaningful improvements without changing every surface in the house. Many projects begin by addressing the fundamentals that affect air quality and comfort: air leaks, insulation gaps, ventilation, and humidity control. These upgrades can reduce dust, improve temperature consistency, and help prevent moisture-related issues that contribute to odors or allergens. From there, a remodeling plan can prioritize healthier interior materials and finishes. That might include replacing wall-to-wall carpet with natural or low-emitting flooring, using low-toxicity paints and sealants, upgrading to better filtration, or selecting cabinetry and trim materials designed to reduce formaldehyde exposure. Remodeling with a health focus is also a smart moment to improve efficiency—so you get a home that feels better to live in and performs better over time.

Does healthy home construction cost more?

It depends on the level of customization and the specific materials you choose. Some non-toxic and low-emitting products cost more upfront, but many healthy-home decisions are about smarter specifications and good sequencing rather than “luxury upgrades.” For example, prioritizing air sealing, ventilation planning, and right-sized HVAC can improve comfort and indoor air quality without necessarily adding significant cost—especially when those decisions are made early. Where costs can increase is when you select premium natural materials, specialty finishes, or higher-end mechanical systems. The tradeoff is often long-term value: durability, fewer replacements, better energy performance, and a home environment that supports wellness. We work with you to prioritize the upgrades that matter most—so your budget aligns with your health goals and you avoid spending on features that look “healthy” but don’t move the needle.

What are the benefits of working with custom healthy home builders?

Working with custom healthy home builders gives you control over the details that make the biggest difference for how your home feels—air quality strategy, material selections, and design decisions that support daily wellness. Instead of fitting your lifestyle into a standard set of finishes, you can choose low-toxicity options, allergen-conscious flooring, better filtration and ventilation, and moisture-aware assemblies that match Central Texas conditions. You also have the opportunity to design for comfort in ways that directly affect health, like acoustic control, glare management, and consistent temperatures from room to room. Custom building is also where performance and aesthetics can work together. Want brighter spaces with healthier daylight, but without excess heat gain? Prefer durable, easy-to-clean finishes that don’t rely on harsh chemicals? Need a layout that supports sleep, recovery, or a home office routine? A custom-built healthy home is about aligning design, systems, and materials so the finished space supports both your personal style and your long-term peace of mind.

WHAT HEALTHY BUILDING IN CENTRAL TEXAS ACTUALLY REQUIRES

There are some important factors to consider when building a healthy home in our beautiful Texas Hill Country region. It's important for homeowners who want to prioritize healthy construction in Central Texas to understand these important building factors.

Central Texas presents a set of environmental conditions that make healthy home construction not just a wellness preference, but a practical necessity for long-term comfort. The same climate that makes this region so appealing to live in creates real challenges for indoor air quality, moisture management, and occupant health — challenges that a conventional builder will rarely address adequately, because addressing them requires expertise most builders simply haven't developed.

Here's five important considerations when building a healthy home in Central Texas:

1. The Central Texas Allergen Load Is Among the Highest in the Nation

Austin and the surrounding Hill Country region consistently rank as one of the worst places in the country for seasonal allergies. Mountain Cedar (Ashe juniper) releases pollen from December through February in concentrations that can be visible as a haze over the landscape. Oak and elm follow in spring. Live oak contributes year-round. For the roughly 30% of the population with allergic sensitivities, the difference between a home with a tight envelope, proper filtration, and controlled ventilation and one without is the difference between a refuge and an extension of the outdoors.

Non-toxic home builders who understand this region design for it specifically. That means MERV-13 or better filtration, ERV or HRV systems that exchange air without simply opening the building to whatever is floating outside, and building envelopes detailed to minimize infiltration at every penetration, joint, and transition.

2. Heat and Humidity Create Chronic Moisture Risk

Central Texas summers are long and brutal, and the combination of high outdoor humidity and aggressively air-conditioned interiors creates condensation risk in poorly detailed walls and roof assemblies. This is one of the primary pathways to mold growth in homes that were built without deliberate moisture management — not a one-time flood event, but chronic seasonal moisture accumulation inside wall cavities where nobody looks until there's a problem.

Healthy construction in this climate means getting vapor management right during design: choosing insulation assemblies appropriate for a mixed-humid climate zone, detailing window and door openings to drain rather than trap water, and sizing HVAC systems to manage latent (moisture) load as carefully as sensible (temperature) load. An oversized AC system that short-cycles — a very common condition in Central Texas — cools the air quickly but doesn't run long enough to pull adequate moisture out of it. We address this at the design stage, not after the fact.

3. EMF Awareness in Modern Home Construction

Building a healthy home today also means thinking carefully about electromagnetic field exposure from wiring, smart home systems, and wireless infrastructure. This is an area where JS2 Partners has developed specific knowledge and protocols — from wiring methods that reduce magnetic field exposure to thoughtful placement of wireless infrastructure for clients who prefer to minimize RF exposure in sleeping areas. It's a dimension of healthy construction that virtually no other builder in Central Texas addresses with any depth, and it's one our clients increasingly ask about by name.

4. Radon and Soil Gas in the Hill Country

Radon is a naturally occurring radioactive gas that enters homes through foundation penetrations and cracks, and the geology of the Texas Hill Country — particularly limestone-dominant formations — produces meaningful radon concentrations in some areas. Non-toxic home construction in this region includes radon-resistant construction detailing as a standard practice: sub-slab depressurization systems, sealed foundation penetrations, and provisions for active radon mitigation if post-construction testing warrants it. Most builders in the region don't raise this topic. We do, every time.

5. Central Texas Wildfire Smoke and Exterior Air Quality

Wildfires are an increasing reality across the Texas Hill Country and western Central Texas, and smoke events — whether local or drifting from west Texas and New Mexico — can degrade indoor air quality significantly in homes without proper filtration and envelope control. A well-built healthy home with quality filtration and a tight envelope will maintain dramatically better indoor air quality during smoke events than a conventionally built home. For clients building in fire-adjacent areas, this is a meaningful health consideration that shapes both the building envelope design and the mechanical system specification.

THERE ARE A LOT OF HEALTHY HOME BUILDERS IN CENTRAL TEXAS — WHAT'S DIFFERENT ABOUT THE JS2 PARTNERS APPROACH?

“When it comes to choosing a healthy home builder, it's important to not just settle on the lowest bid. We believe your home is a sanctuary, built to promote wellness, comfort, creativity and rest. A well-built home is an investment in your family's health as much as it is an investment in real estate.”

Healthy home construction isn't a service offering JS2 Partners added on — it's the reason the company exists. Jen Stout built the first healthy home after her own home was making her sick, and what she and Rusty learned from that experience became a proprietary construction methodology they've spent over a decade refining, work recognized by Forbes, Builder Magazine, and the Wall Street Journal as some of the most influential healthy building research in the industry.

That depth of focus is the difference between a builder who offers “low-VOC options” and a builder who has spent years researching exactly what's in every material category, literally writing the book other builders now reference. Rusty's three decades in Texas construction means that expertise isn't theoretical — it's been applied and refined across hundreds of real Central Texas projects, in the same climate and conditions your home will face.

Healthy building is a whole-home philosophy at JS2, not a menu of upgrades layered onto a standard build. Here's who tends to be the best fit for that approach.

You've Lived in a Home That Made You Feel Sick

This is where our story starts — literally. Jen Stout built the first healthy home because her own home was destroying her health. If you've experienced chronic fatigue, congestion, headaches, or a general sense of feeling “off” indoors — especially if symptoms improved when you traveled or spent time away — you already understand viscerally what indoor air quality means.

Our clients who've had this experience don't need to be convinced. They've already paid the cost of not prioritizing it, and they're not interested in a builder who treats healthy construction as a marketing checkbox.

Someone in Your Household Has Sensitivities or Respiratory Conditions

Chemical sensitivities, MCS, asthma, mold illness, and severe seasonal allergies are conditions where the built environment makes a documented, measurable difference in daily quality of life. These aren't abstract wellness concerns — they're conditions where the wrong building material, the wrong ventilation strategy, or a poorly sealed envelope can be the difference between a livable home and one that actively undermines someone's health every single day. For these households, non-toxic home construction isn't a preference — it's a functional requirement, and treating it as anything less is a disservice to the people who'll actually be living there.

We have deep experience designing and building for clients with serious sensitivities, and we know how to ask the right questions to make sure your home actually supports your health rather than just claiming to on a spec sheet. That means going beyond standard low-VOC labeling to understand exactly what triggers a specific sensitivity, and building a material specification around that reality rather than a generic healthy-home checklist.

You Have Young Children or Are Planning a Family

Children's developing neurological and respiratory systems are disproportionately affected by indoor air pollutants. The first years of life, spent predominantly indoors, are when this exposure matters most — and it's also the window where the cumulative effects of a poorly built home are hardest to see until years later, when the damage is already done. Parents who understand this tend to be among our most motivated clients — they're not building a healthy home for marketing reasons or because it's trending.

They're building one because they want their children to grow up in a genuinely safe environment, and they're willing to ask the harder questions to get there. We welcome those questions, because they're exactly the ones that should be asked before construction begins, not after a child starts showing symptoms nobody can explain.

You Want to Understand What Goes Into Your Home

Our clients ask questions. They want to know why we specify a particular insulation type over another, what makes one paint genuinely zero-VOC versus one that's just labeled that way, and how we evaluate a material's health profile against the dozens of competing options on the market. We welcome this, because it's exactly the kind of scrutiny healthy home construction should be able to withstand.

Transparency is foundational to healthy home construction services done right — if a builder can't explain why they're using what they're using, that's a problem, not a minor gap. We can walk you through every decision in your material spec and explain the reasoning behind it, from the framing lumber to the final coat of paint, so you're never taking our word for it on faith alone.

You May Not Be the Right Fit If...

Healthy building is a whole-home philosophy, not a menu of optional upgrades applied to a conventional build. If you're looking to add a few non-toxic finishes to an otherwise standard construction project, there are contractors who can accommodate that approach more efficiently than we can.

Our non-toxic home construction process is integrated from the first material specification to the final walkthrough — and the clients who get the most out of it are the ones who embrace that from the start, not the ones looking for a partial solution.
