I would focus first on the systems that protect the home from moisture, wildfire smoke and embers, indoor-air-quality problems, and plumbing leaks—because those decisions are much harder and more expensive to correct after construction is complete. In this episode, I'm walking through the healthy-home strategies I would prioritize for my own family while working within a realistic budget. My choices are shaped by Southern California's small lots, seismic requirements, coastal moisture, and wildfire risk, but the planning principles can be adapted to other climate zones. I would start with a two-story home on a concrete foundation to make the most of a limited Orange County lot. If feasible, I would raise the interior floor with a taller stem wall and install a vapor barrier below the slab so moisture in the soil is separated from the concrete and the living space above it. For the enclosure, I would build watertight and airtight exterior walls using a well-detailed water-resistive barrier such as the ZIP System or a self-adhered membrane. I would add exterior rigid mineral-wool insulation for thermal performance and fire resistance, then use a sealed, unvented attic to reduce the pathways through which wildfire embers and smoke can enter the home. Inside, I would choose paperless drywall to reduce the amount of paper facing that can support problems when moisture reaches the back of a wall. Quality control would be part of the build—not something left until a problem appears. I would leak-test the exterior walls, windows, and roof before insulation and drywall conceal the assemblies. Finding and correcting a leak during construction provides far more peace of mind than discovering hidden water damage five or ten years later. I would also invest in a properly calculated mechanical design based on the home's actual enclosure and climate. In wildfire country, that includes dampers that can close exterior openings, along with effective filtration, fresh-air ventilation, dehumidification, and an ERV designed to work with an airtight home instead of treating each piece of equipment separately. Finally, I would create a whole-home leak-management plan. A floor drain in the laundry room, a whole-home leak detector and automatic shutoff, separate irrigation controls, and accessible plumbing connections can limit damage from a failed appliance or supply line. When the family leaves for vacation, the domestic water can be shut off without affecting the landscaping. A healthy home should feel like a sanctuary—not a source of fear about water damage, mold, toxins, or hidden failures. The goal is to make the highest-value decisions early so the enclosure, mechanical systems, and plumbing protections work together for the family living inside. In today's episode, we're talking about: - How lot size, climate, and budget shape healthy-home priorities - Why a raised foundation and under-slab vapor barrier help manage moisture - How airtight walls, exterior insulation, and an unvented attic support resilience - Why leak testing should happen before insulation and drywall - What a wildfire-aware mechanical and ventilation strategy can include - How whole-home leak detection and shutoff systems create peace of mind

You may already have an architect and a builder—but does that mean you have every perspective your healthy home needs? Not necessarily. The real question is whether your plans fully document your materials, quality standards, and building-science expectations before construction begins.

In this episode, Christine breaks down what your architect and builder should each be responsible for, why permit-ready plans often leave major gaps, and how to tell whether your existing team is equipped to deliver the healthy home you expect.

A strong architect should do far more than create a beautiful layout and submit plans for permitting. Your schematic design, design development, and construction documents should capture the decisions that matter—from the foundation and exterior walls to insulation, waterproofing, mechanical systems, plumbing, flooring, and material specifications. If those expectations are not documented, they can be missed, miscommunicated, or priced inaccurately.

Your builder's role is to implement those construction documents, manage the schedule and subcontractors, and send documented requests for information back to the architect when questions arise. When plans lack detail, builders are forced to make decisions during construction based on habit or a previous project—and that may not align with the healthier materials or methods you intended.

If your architect provides robust plans, specifications, material selections, quality-control details, and construction administration—and your builder understands healthy-home building science—you may not need a consultant. If those pieces are missing, a healthy-home consultant can help close the gaps before they become expensive problems on site.

In today's episode, we're talking about:

- How to assemble the right team for a new build or major renovation

- The architect's role from schematic design through construction documents

- Why permit-ready plans may not be detailed enough to protect your expectations or budget

- How specifications and material selections create clearer, more accurate bids

- Why construction administration and the RFI process matter

- What your builder should implement—and what should not be improvised mid-build

- The signs that your team is complete and when a healthy-home consultant can add value

If you think buying the most expensive water filtration system automatically means you're getting the cleanest water, you may be wasting thousands of dollars while still missing the contaminants that matter most. Every home has different water, different plumbing, and different filtration needs—which means there is no one-size-fits-all solution.

Today, I'm sharing how to confidently navigate water filtration, understand your options, and choose a system that's actually designed for your home's unique water quality.

Over the past year, I've helped families across the United States design healthier homes from the ground up, and water quality is becoming one of the biggest questions clients ask. Whether we're working on a custom home or evaluating an existing property, every recommendation starts with data—not marketing. The right solution depends on your local water supply, your plumbing system, your lifestyle, and the level of filtration you actually need.

Recently, one of my clients came back after months of planning because they wanted to revisit their water filtration system. New concerns about PFAS, pharmaceuticals, and other emerging contaminants made them question whether the system we had originally selected was still the best fit. Instead of simply upgrading to a more expensive unit, we went back to the beginning, evaluated their water again, and looked at exactly what needed to be filtered.

That process highlights one of the biggest misconceptions I see. People spend hours comparing brands before they even know what's in their water. The better approach is understanding your water source, evaluating whether you have municipal or well water, considering your plumbing materials, deciding between whole-home and point-of-use filtration, and planning for long-term maintenance before making a purchase. Those decisions ultimately determine whether your filtration system actually delivers healthier water for your family.

In today's episode, we're talking about:

- How to determine what contaminants are actually in your water

- PEX vs. copper plumbing and how each impacts water quality

- Whole-home filtration versus reverse osmosis drinking water systems

- The upgrades worth considering, including pre-filters, UV sanitation, and water restructuring

- How to choose, install, and maintain the right filtration system for your home

If you think your job is done the day you get the keys to your new home, think again. The first 90 days after move-in are some of the most important for protecting your investment, your indoor air quality, and your family's health. Miss these simple steps, and you could be setting yourself up for expensive repairs, hidden leaks, poor air quality, and preventable equipment failures.

Today, I'm sharing the five most important things every homeowner should do during the first 90 days after moving into a new build or newly renovated home.

Over the past year, I've worked with homeowners across the United States designing and consulting on healthy homes ranging from modest family residences to luxury custom estates. One thing I've consistently seen is that homeowners receive the keys but rarely receive the guidance they need to properly operate and maintain their homes. The first few months set the foundation for years of healthy living and can help prevent thousands of dollars in future repairs.

Too often, homeowners focus on unpacking furniture and decorating while overlooking the systems that keep their home functioning. They don't know where the main water shutoff is, how to maintain their HVAC system, or how to recognize early warning signs that something isn't performing properly. Even brand-new furniture can introduce VOCs into an otherwise healthy home, while hidden plumbing leaks often go unnoticed until significant damage has already occurred.

In this episode, I walk you through the exact five-step plan I recommend to every homeowner after move-in. From establishing baseline indoor air quality data and implementing a leak management strategy to creating a seasonal maintenance schedule, these proactive steps help you protect your investment, extend the life of your home's systems, and create a healthier environment for years to come.

• The critical home systems every homeowner should understand on day one
• How to manage furniture and material off-gassing after move-in
• Why collecting baseline indoor air quality data matters
• Building a leak management plan before problems happen
• Creating a seasonal maintenance schedule that protects your home long-term

If you think an attached garage is simply a convenience, you may be overlooking one of the biggest sources of air contamination in your home. Every day, garages store cars, fuel, paints, chemicals, and equipment that can introduce pollutants into your living space—even when building code requirements have been met.

Today, I'm sharing why garage design plays a much bigger role in a healthy home than most people realize, what actually happens when garages share walls with living spaces, and the strategies I recommend during the planning stage to prevent these issues before construction even begins.

Every year, I work with homeowners, architects, and builders across the United States designing healthier custom homes where every construction detail is intentional. One of the most overlooked conversations happens before the foundation is ever poured: deciding whether a garage should be attached or detached. While building codes focus heavily on fire protection, they don't fully address how air, fumes, and contaminants move between the garage and your living environment.

One of the biggest misconceptions I see is assuming that a fire-rated wall automatically protects your family's health. In reality, garages and living spaces function completely differently. Garages are designed to store vehicles, fuel, paints, chemicals, and equipment while also being naturally ventilated. Your home, on the other hand, is designed to be airtight and energy efficient. That pressure difference can actually pull garage air into your living space if proper air sealing isn't part of the design.

I also share a real case involving an Airbnb in Las Vegas where a hidden chemical laboratory inside an attached garage led to serious health issues for a cleaning professional who never even entered the garage. It's an important reminder that what happens inside an attached garage doesn't always stay there. Whether you're building a new home or renovating an existing one, thoughtful planning, proper air sealing, and, when possible, choosing a detached garage can dramatically improve your home's long-term health and performance.

• Why attached garages can introduce contaminants into your home
• The difference between fire protection and air sealing
• Why detached garages simplify healthy home construction
• How to properly design an attached garage when one is necessary
• Why ventilation and mechanical systems should remain completely separate

If you think summer is the easiest season on your home, you may be overlooking some of the biggest moisture, humidity, and maintenance risks of the entire year. I've seen homeowners spend thousands of dollars dealing with preventable water damage, mold growth, HVAC failures, and hidden leaks that started with something as simple as a clogged condensate line or unchecked humidity levels.

Today, I'm sharing the six maintenance items I recommend tackling before summer heat waves arrive, along with the systems and checkpoints that help keep your home healthy, efficient, and protected all season long.

In 2025 alone, my team worked on projects across multiple climate zones, helping homeowners evaluate everything from HVAC performance and attic conditions to moisture management and indoor air quality. One thing remains consistent regardless of location: homes perform better when maintenance is proactive rather than reactive, especially during periods of extreme heat and humidity.

One of the most common issues I encounter is homeowners focusing exclusively on temperature while completely overlooking humidity. A home can feel cool while still harboring excessive moisture levels that impact indoor air quality, building materials, and long-term durability. Add an attic with inadequate ventilation, bathroom exhaust fans dumping moisture into the attic, or deteriorated weatherstripping around doors and windows, and you've created conditions that can quietly lead to much larger problems.

The good news is that most of these issues are preventable. I walk through exactly what should be serviced, monitored, cleaned, and inspected before summer arrives. From flushing condensate lines and cleaning HVAC coils to monitoring attic moisture content and replacing neglected filters, these simple annual habits can help prevent costly repairs and create a healthier living environment for your family.

• Why your HVAC system needs more than just a filter change before summer
• How attic temperature and humidity can impact your home's health
• The hidden dangers of bathroom exhaust fans venting into attics
• Why every room should have humidity monitoring
• Exterior inspections, weatherstripping, screens, and air sealing
• The annual filter and coil maintenance most homeowners forget
• How to prepare your home for vacation mode before traveling

If you think passing city inspections means your home is protected from mold, leaks, and construction defects, you may be making a very expensive mistake. Building inspectors are there to verify minimum code requirements, not to ensure your home is healthy, watertight, or built to your personal standards. Missing the right inspections during construction can lead to hidden failures that aren't discovered until years later.

Today, I'm sharing the four independent inspections I consider non-negotiable during a custom home build if your goal is a healthy, high-performance home.

In 2025 alone, my team worked on projects across the United States, helping homeowners navigate the complex realities of healthy home construction. One of the biggest patterns I continue to see is that many costly defects could have been prevented with a few strategic inspections performed at the right time. These inspections often cost only a few hundred dollars, yet they can identify issues that would cost tens of thousands to repair after construction is complete.

One of the most common mistakes I see is homeowners relying exclusively on city inspections. While permit inspections are important, they are designed to verify minimum building standards, not evaluate moisture content in framing, hidden plumbing issues, window performance, or the long-term durability of the home. By the time a problem becomes visible, the damage is often already done.

That's why I encourage homeowners to bring in independent inspectors who work directly for them. From verifying foundation preparation before concrete is poured, to inspecting framing before drywall covers everything, to performing leak testing on windows before move-in, these inspections create accountability and uncover issues while they are still easy to fix. I also share why one of the most overlooked inspections happens after construction is complete: your warranty inspection before the builder's warranty expires.

• Why building code inspections are only the minimum standard
• The importance of pre-foundation inspections
• What to look for during a pre-drywall inspection
• Why window leak testing is worth the investment
• How warranty inspections protect homeowners after move-in

If you think all building materials are basically the same, you could be making decisions that impact your family's health for years to come. Some of the most commonly used products in construction today can contribute to poor indoor air quality, moisture problems, mold growth, and costly remediation down the road.

Today, I'm sharing my material blacklist — the building materials I avoid whenever possible and the healthier alternatives I recommend instead.

In 2025, I consulted on healthy home projects across the United States, helping homeowners make informed decisions about every layer of their homes, from insulation and exterior assemblies to paint, flooring, and millwork. One of the biggest mistakes I see is assuming that common building materials are automatically the best choice simply because they're widely used. The reality is that every material selection has a good, better, and best option depending on your health goals, budget, and climate.

In this episode, I break down the materials that consistently raise concerns during my consulting projects and explain why they can create problems long after construction is complete. From conventional paints and cabinetry finishes to MDF trim products, spray foam insulation, and vinyl flooring, many of these materials are installed in massive quantities throughout a home. When you look at them individually, they may seem insignificant. But when combined, their impact can be substantial.

I also explain what healthier alternatives look like and how to have productive conversations with your architect, builder, and interior designer before construction begins. Because once some of these materials are installed, replacing them can be difficult, expensive, and disruptive. The goal isn't perfection — it's making informed decisions that support better indoor air quality, moisture management, and long-term durability.

• Why conventional paints can impact indoor air quality beyond VOC levels
• The hidden concerns with MDF, OSB, and composite wood products
• Why spray foam remains one of my most controversial blacklist materials
• How vinyl flooring and wallpaper can contribute to moisture problems
• Healthier material alternatives for a cleaner, more durable home
