“to the pure mold masters team, thank you for all your help during this crazy process! you guys did excellent work and were a pleasure to work with!!”
“Matt and his company did a great job removing the mold from our new resident in Irvine. We discovered the mold weeks after we moved into a new home, so it was very disturbing. From start to finish, Matt and his team were respectful, professional and answered all of our questions. The inspection and treatment were simple. Happy with the final results.”
“Matt and his team are world class. Wouldn’t go anywhere else for any mold issues I needed help on. Best price and best quality out there.”
“Matt and his team are incredibly awesome from front office to technician, everything was handled, professionally, timely, and thoughtfully! They go the extra step and offer any help needed especially to put your mind at ease. 10/10 would call them up again!”
“They are an excellent team that is always punctual and offers reasonable prices. They also have great communication skills.”
“Matt and his technician were amazing. I couldn't figure out why I was sick for so long until my friend recommended me to these guys. The inspection was smooth, the technician Cody was very respectful and didn't waste any time. My questions were all answered promptly. We set the appointment and got my house fogged and all the mold is now gone. I'm no longer sick after 6 weeks straight. THANK YOU!! 10/10 would recommend.”
Our patented vapor system treats surfaces, hard-to-reach void spaces, and the air in your home — not just the places you can see. So the air your family breathes the night we leave is measurably cleaner.
In and out in a single day. No relocation, no multi-week disruption.
It breaks down into acetic acid (white vinegar), oxygen and water shortly after treatment.
Every treatment is verified by an accredited third-party lab analysis. We stand behind our work — if the result doesn't hold, we make it right.
VaPURE™ vapor reaches surfaces, indoor air, wall cavities, and HVAC — the 90% of the home where conventional crews can't go.
Vapor reaches what scrub-and-cut crews need to break walls to find. Less mess, less rebuild, less cost.
We test the air before and after. You get the lab result on paper.
Santa Ana is an old city by Orange County standards. Most of its homes went up before 1980, from the 1920s bungalows of Floral Park and Washington Square to the stucco tract homes and apartment blocks of the 1950s, 60s, and 70s. Add a coastal climate and you get moisture that lingers where you cannot see it. We are based at the Tustin end of Santa Ana, so most jobs are a short drive.
Book Free ConsultationPure Mold Masters is the only Orange County practice exclusively licensed to use Pure Maintenance's patented VaPURE™ vapor treatment — the same technology studied by the U.S. Army Corps of Engineers. It treats mold on surfaces and in the air, penetrating wall cavities, HVAC, and porous materials at the spore level — using an active ingredient on the EPA's Safer Chemical Ingredients List.
VaPURE™ wins where it matters most: lab-verified results, whole-home reach, and a treatment that leaves your home (and your belongings) where you left them. Here's how it compares against the alternatives.
We treat single-family homes, multi-unit residential buildings, and commercial properties across Orange County. The same patented VaPURE™ vapor, the same accredited third-party lab verification, scaled to your site.
Book Free ConsultationEvery project follows the same protocol — diagnose, treat, prevent, prove. Here's the high-level view; the detailed walkthrough follows below.
We inspect your property to find any visible mold growth and the moisture conditions causing it. Air samples are sent to an accredited third-party lab.
Our patented VaPURE™ vapor disperses our sterilant as a vapor that reaches most places mold lurks, treating mold on contact.
Our antimicrobial protectant bonds to surfaces, electrostatically attracting spores and mechanically disrupting them on contact.
Post-treatment air samples go back to the same accredited lab. You get a written before-and-after report — and we don't close the job until the spore counts clear.
Every project follows the same protocol — diagnose, treat, prevent, prove. No improvisation, no upsells, no surprises.
Free · No obligation
Every home is different, and the causes of mold growth could be numerous. Mold can be caused by moisture conditions, structural defects, or a blend of factors. Our specialist technicians help you understand why your home has a mold problem so we can tailor the treatment accordingly.
Our expert technicians use a suite of professional diagnostic and screening tools, combined with their knowledge, to offer insights on the indoor air quality and mold load in your home. We'll use tools on a case-by-case basis ranging from the Instascope, Air-O-Cell tests, Via-Cell tests, moisture readers, and more.
Single-day treatment
The treatment applies a fine vapor of EPA-registered products, each applied exactly as its label directs. Our proprietary technology is designed for thorough coverage, penetrating even the most hard-to-reach areas.
Treatment is delivered in a single visit, with typically no demolition and no relocation required. Most families are back in their home the same evening.
Protective barrier
We apply an antimicrobial coating that forms a covalent bond with critical surfaces, creating a long-lasting protective layer that doesn't wash off.
The coating electrostatically attracts mold spores and other microbes, drawing them into contact with the surface and mechanically neutralizing them — keeping your home protected long after we've left.
Third-party verified
Our work is verified by independent scientists working in a third-party, accredited lab. Post-treatment air samples are collected and analyzed against the original baseline — and you get the full report.
We don't ask you to take our word for it. The VaPURE™ approach is backed by independent research published in indexed journals.
A six-month evaluation by the Army's Engineer Research and Development Center of the VaPURE™ application system on two occupied buildings at Fort Campbell, Kentucky — measuring both initial efficacy and recurrence.
A compiled set of GLP-compliant independent laboratory tests of the vapor peracetic acid (VPA) treatment against mold, bacteria, and viral targets — the underlying chemistry behind the Pure Mold Masters VaPURE™ process.
A technical explainer of the three "magic-bullet" variables — 7.5μm particle size, vapor phase change, and dwell time — that make the treatment behave like a gas and reach where surface cleaning never does.
The time varies based on size and scope. Typical home treatments can be completed in 4 to 6 hours.
Costs vary with the unique circumstances in your home that caused mold growth. We tailor our treatment to ensure the best results. Because VaPURE™ technology is non-invasive, it is often cheaper than traditional mold remediation methods.
No visible residue. The vapor evaporates as it works.
Leave as many personal belongings in the building as possible. Inform your technician of any brass materials inside the home so they can apply the treatment accordingly.
People and pets stay out during the treatment itself. After the treatment cycle and proper ventilation, most families are back home the same day.
The treatment treats the mold present at the time of treatment, and the antimicrobial protectant continues to work against new spores after we leave. As long as the underlying moisture conditions are resolved, the treatment should not need to be repeated. We re-treat at no cost if a follow-up lab test shows it didn't take.
We don't scrape, demolish, and replace — that's the conventional approach. VaPURE™ is a vapor that behaves like a gas, reaching the 90% of a home where mold actually lives (porous materials, wall cavities, HVAC). Same outcome, less invasive, lab-verified at the end.
Yes. Downtown, Floral Park, French Park, Delhi, Willowick, South Coast Metro, and the unincorporated North Tustin pocket where we are based. We also treat homes across the rest of Orange County.
Not on its own. The second stage of the treatment leaves an antimicrobial protectant on treated surfaces that keeps working against new spores. If a leak or a wet crawl space stays wet, mold can return anywhere, so we show you the moisture source and what to fix. If a follow-up lab test shows the treatment did not hold, we re-treat at no cost.
Attic, crawl space, bathroom, HVAC, or the whole house: each has its own page, written for Santa Ana homes. Start with the one that matches what you are seeing.
The first step is a free telephone consultation with a specialist. It helps you understand why you have mold, the causes, and what can be done about it — including Pure Mold Masters services, availability, and pricing.
A small, senior team — so we treat each home like the only one we're working on this week. Currently accepting new clients across Orange County.
