Professional indoor air quality treatment and remediation for mold spores, VOCs, allergens, and more.
The air inside your home or business can be up to five times more polluted than the air outside. Mold spores, VOCs, pet dander, dust mites, and chemical off-gassing all contribute to poor indoor air quality that affects sleep, focus, and long-term health. We take baseline readings, treat the source, and document the result — then put proven technologies in place to keep your air clean.

Our Process
Air Quality Baseline
Davis AirLink monitoring establishes your baseline — particulates, VOCs, and humidity — with independent lab sampling coordinated when needed.
Source Identification
We locate the root cause — mold, HVAC issues, building materials, or occupant activity.
Remediation
HEPA air scrubbing, hydroxyl treatment, and source removal address the contaminants.
Technology Installation
Air purification systems and UV-C systems are installed to maintain long-term air quality.
Post-Treatment Verification
Follow-up readings document the improvement, with independent clearance testing available on request.
What is actually in the air indoors
Indoor air is routinely more polluted than outdoor air, and the reasons are mundane rather than exotic. Cooking and combustion put particulates in the air. New flooring, paint, cabinetry, and furniture off-gas volatile organic compounds for weeks to months after installation. Pets, carpet, and soft furnishings hold dander and dust. Damp basements and crawlspaces contribute mold spores and the musty compounds that go with them. Modern tighter building envelopes make all of this worse, because the air exchanges with outside less often than it used to.
Treatment versus masking
A plug-in air freshener changes what you smell. It does not change what you are breathing. Real air quality work means removing particulates with HEPA filtration sized to the space, addressing the moisture that lets biological growth continue, and where appropriate running hydroxyl treatment that breaks down odor compounds rather than covering them. Where the underlying cause is structural — a crawlspace with no vapor barrier, a bath fan venting into an attic, a dehumidifier that has been unplugged since spring — we will tell you that, because no amount of scrubbing outruns a moisture source.
Readings before and after
Every treatment is bracketed by measurements: particulates, VOCs, humidity, and temperature, recorded before we start and after we finish. You keep those readings. They are useful for a property manager documenting proactive maintenance, for a seller answering a buyer's question, and for anyone who simply wants to know whether the money did anything. When laboratory sampling is warranted, collection is handled by an independent certified assessor and analyzed by an accredited lab — we do not verify our own results.
When air quality treatment makes sense
- A persistent odor that returns after regular cleaning
- Recent renovation, new flooring, or fresh paint in an occupied space
- Indoor humidity that stays above roughly 60 percent
- A recent water event, even one that was dried
- A property turnover where the previous occupant smoked or had pets
- Dust that reappears on surfaces within a day or two of cleaning
Air Quality Restoration: common questions
What does an air quality treatment actually involve?
We take baseline readings, run HEPA air scrubbing sized to the volume of the space, address humidity, and where odor compounds are present run hydroxyl treatment. Depending on what is driving the problem it may also involve surface cleaning or source correction. At the end we take a second set of readings and hand you both. A typical residential treatment is a single visit; larger or more contaminated spaces may need an overnight cycle.
Do you test the air?
We take equipment readings — particulate counts, VOC levels, humidity, and temperature — before and after treatment, and those are yours to keep. Formal air sampling and laboratory analysis is a separate discipline that we deliberately keep independent: it is collected by a certified third-party assessor and analyzed by an accredited lab. We handle the treatment side.
Is it safe to be in the building during treatment?
HEPA scrubbing is safe in occupied spaces and can run continuously. Hydroxyl treatment is generally used in occupied-safe configurations, but we will tell you clearly which parts of a given job require the space to be vacant and for how long. Ozone, which is not safe to occupy during use, is only used in unoccupied spaces with a clearance period afterward.
How long do the results last?
That depends entirely on whether the source was addressed. Treating air in a space with an ongoing moisture problem produces a temporary improvement. Treating air after the moisture is corrected produces a lasting one. This is why we spend time identifying what is generating the problem instead of just cycling equipment.
Will this help with allergies or asthma?
We are not able to make medical claims, and we would be cautious of any contractor who does. What we can say factually is that treatment reduces measurable airborne particulates and VOCs, and that we document the before and after so you can see the change. Whether that affects a particular person's symptoms is a question for their physician.
