If you have spent any time in the healthy living world, you know that what we put in our bodies matters. But when it comes to the four walls around us, things get complicated. You decide to renovate a bathroom or finish a basement, and suddenly you are faced with a dizzying array of adhesives, paints, and industry standards that do not actually align with health. You want to hire a contractor who understands that a home should be a sanctuary, not a source of chemical off-gassing.
The truth is, most builders are trained for speed and aesthetics, not for indoor air quality or building biology. But you do not have to be an expert in construction to get the results you want. You just need the right strategy to hire a contractor who respects your standards. This guide will walk you through the science, the specialized trades, and the exact steps to ensure your next project supports your family’s wellness.
Why the Science of Building Materials Matters
When you hire a contractor, you are essentially inviting a chemistry set into your home. Many conventional building materials contain volatile organic compounds, phthalates, and flame retardants. Research from the Environmental Protection Agency suggests that indoor air can be two to five times more polluted than outdoor air, largely due to the materials we use.
Building biology is a science that originated in Germany and focuses on the relationship between the built environment and human health. It emphasizes the use of natural, vapor-diffusive materials that do not trap moisture or emit toxins. Scientific studies, such as those published in the journal Environmental Health Perspectives, have linked the chemicals found in common flooring and wall coverings to endocrine disruption and respiratory issues. This is why the vetting process is so vital when you hire a contractor.
How to Begin Your Search to Hire a Contractor
This is really a great way to start, because you may be able to find what you’re looking for with just a few of the right key terms. Some of the best terms to use are:
- Eco Friendly
- Green
- Healthy
- Toxin Free
- Non Toxic
- Organic
- Natural
- Chemically Sensitive
You would then pair them with whatever type of contractor you’re hunting for:
- General Contractor
- Carpenter
- Carpet Contractor
- Handyman
- Tile Installer
- Drywaller
- Plastering Contractor
- Painter
- Masonry Contractor
- Remodel Contractor
- Plumber
- Electrician
- Home Builder
- Home Remodeler
- Waterproofing Company
So how do you go about finding a contractor who is a little more willing than the typical contractor out there. Often you can find someone to work with by asking a few key questions when you’re interviewing them either by phone or email.
I will also remind you that contractors are typically quite busy, so just a few key questions should be all you ask right off the bat. Try not to waste your time or their time if you’re unsure you’ll be hiring them. Once you’ve decided you might like to hire this particular contractor, you can expand your questions to more as they bid your job and you get to know them.
Some first questions that are important to ask are:
- “Have you worked on any projects that involved toxin free products or materials?”
- “I’m interested in using more natural products for this project, are you familiar with any that relate to my job?”
- “How do you plan to minimize dust and debris during the project?”
- “Are you willing to use materials and products that I provide?”
- “Do you have experience working with chemically sensitive families?”
Navigating Different Types of Specialized Trades
To hire a contractor effectively, you must understand how different trades impact your home’s ecosystem. Every professional who enters your home has the potential to improve or degrade your environment.
The HVAC Specialist and Air Quality
Your heating, ventilation, and air conditioning system is the lungs of your home. When you hire a contractor for HVAC work, they should understand advanced filtration and the importance of balanced ventilation. Poorly installed ductwork can become a breeding ground for mold if humidity is not managed, which is a core concern in managing indoor air quality.
The Plumber and Water Purity
Plumbing is not just about leaks; it is about water quality. A healthy home focused plumber will be open to installing whole house filtration systems and will be mindful of using lead free solders and low toxin piping materials.
The Tile and Flooring Installer
This is where many toxins enter through adhesives and thin-sets. When you hire a contractor for tile, you want someone willing to use solvent free mortars and non toxic grouts. Many standard floor installers rely on high VOC finishes that can off-gas for months.
The Painter and Drywaller
Drywall compounds and paints are large surface area emitters. You need a team that is willing to work with zero VOC, mineral based, or clay paints. These materials behave differently than standard latex paint, so it is important to hire a contractor with an open mind.
Integrating Building Biology Standards
In my work as a building biology practitioner, I look at the home through the lens of established environmental standards. When you hire a contractor, you can introduce these concepts to them:
- Moisture and Mold: Ensure your contractor uses breathable wall assemblies. If a wall cannot dry out, mold will grow. This is why I often discuss toxin free mold solutions with my clients.
- Electromagnetic Radiation: Many people are surprised to learn that wiring mistakes can create high magnetic fields. When you hire a contractor for electrical work, they should be willing to follow low EMF wiring techniques.
- Particulate Matter: Construction creates fine dust that can settle in your carpets and upholstery. This dust often contains legacy toxins like lead or pesticides. A healthy home contractor prioritizes containment to keep these particles out of your living space.
Specialized Mitigation vs. General Renovation
If your project involves active mold, high radon levels, or lead paint, you should not hire a contractor that only handles standard renovations for the cleanup.
- Mold Remediators: Look for those who follow professional remediation standards and are open to using botanical cleaners rather than harsh biocides like bleach.
- Radon Specialists: Ensure they are certified and understand how to seal the soil to air interface properly without using high off-gassing sealants.
Vetting Materials: The SDS and MDS Deep Dive
One of the most effective ways to hire a contractor who cares is to ask them to review safety data sheets. However, these documents can be incredibly difficult to decode. An SDS might list a product as safe because it does not cause an immediate chemical burn, but it may still contain ingredients that off-gas for years.
When you hire a contractor, let them know that you will be providing the material specifications. If they seem resistant, it may be a sign that they are not the right fit for a healthy home project. Because this part of the process is so technical, I offer a service where I personally review the SDS and MDS for every product on your list. This takes the research off your plate and ensures that the building materials in your home are truly safe.
Establishing a Healthy Job Site Protocol
Even if you choose the best materials, a messy job site can compromise your health. When you hire a contractor, establish these ground rules from day one:
- Zone Containment: The project area should be isolated using high quality plastic barriers.
- Active Air Scrubbing: Require the use of HEPA air scrubbers to pull fine particulates out of the air during dusty work.
- No Off-Gassing on Site: Prohibit the use of solvent based cleaners or aerosol sprays inside the home.
- Daily Cleanups: A clean site reduces the tracking of toxins into other rooms.
Why You Need a Professional Advocate
It is one thing to have a list of requirements; it is another to enforce them when a project is mid-way through and the pressure is on. This is where I come in. When you hire a contractor, you do not have to be the difficult client. You can let me be your advocate.
I work with homeowners to bridge the gap between health goals and construction reality. I can speak the language of your contractor, explaining the science behind why we are choosing a specific mineral wool insulation over fiberglass, or why we are avoiding certain sealants. This takes the conflict out of your hands and ensures the project stays on track without compromising your wellness.
If you are planning a renovation or a new build, let’s make sure it is done right. You can book a consultation with me to create a customized material list and a strategy for how to hire a contractor who will respect your health focused vision.
HIRE ME TO WORK WITH YOUR CONTRACTOR
Did you know that one of the services I offer is to put together a product list and booklet that you can provide to your contractor? It’s one of the ways I’m able to help many families when they’re remodeling or doing a home project.
If you’ve found a contractor or designer who is willing to use your materials and products, this service is PERFECT to add. Not only will it take the endless research out of your hands, but it also gives you the peace of mind knowing that the product or material going into your house is really safe for your family.
All it takes is a quick consultation via phone or Zoom where I’ll gather information about your project and your family’s needs and desires. From there I get to work creating a plan of materials and building components that your contractor can use for your project. Most families choose to hunt down most of the supplies on their own, however some of the recommendations may be purchased from a showroom or supply store, where contractors often have discounts.
Your plan is a living page on my website and you’ll also receive a PDF that you can print out. I’m available for additional questions throughout your project and we can make changes to your life webpage at any time.
You can set up a consultation by following the link below and getting started. Rates vary depending on how big your project is and how many different materials and items you’ll need.
To hire a contractor who aligns with healthy home principles requires a shift in perspective. It is less about finding a professional who already knows everything and more about finding a partner who is willing to follow a better path. By focusing on science based standards, clear communication, and strict job site protocols, you can create a home that truly supports your family.
You have the power to decide what comes into your home. With a little bit of preparation and the right professional support, your next home project can be a beautiful, healthy success.
