“Great team, great service, very good price. Thank you Matt and team.”
“Recently used Pure Mold Masters to remediate mold that developed from a roof leak. Shout out to Fitzhauer Construction for fixing the roof leak that started the issue. Once we detected the mold ,we got quotes from 3 different contractors.Full transparency - Pure Mold Masters was the most expensive. However, after weighing the convenience factor of not having my kitchen available for 7-10 days (other 2 contractors bids) and the potential damage factor from demo done by the other 2 bidders, the choice was clear. Pure Mold Masters non invasive process was the clear winner for us. The ability to go back to our home the same day with no damage to cabinets or countertops was worth the extra cost. The fogging was very apparent so there was no question whether the process worked. I will say it does have a vinegar smell afterwards for up to 2-3 days but it's not horrible. Still so worth not having all the construction & reconstruction. Highly recommend Pure Mold Masters and would make the same decision again!”
“This is an amazing company with an amazing product. I had mold in my 40 foot coach I could not get rid of. Pure Mold came in and sanitized the inside and cargo bays and got rid of all the mold spores. My wife and I are sleeping and breathing much better. I recommend this product to all RVers! They also can remove mold from your home as well!”
“Pure Mold Masters (PMM) did a great job at my house. My 45-year old house developed a serious case of mold in a crawl space that runs along a foundation wall where an external sprinkler system was over watering without adequate drainage. The PMM team (Matt and Norm) did a great job of assessing the problem. Two other mold remediation contractors gave me quotes, but they didn’t even come close to PMM‘S understanding of the problem. I was especially impressed with their patented approach which removed the mold to my great satisfaction.”
“I cannot recommend Matt highly enough. From the very beginning, he was the first professional who truly listened, investigated thoroughly, and took our concerns seriously. He was the original person who identified the dangerously high moisture levels inside our walls and clearly explained that it was not safe for my children to continue living in the home. That guidance alone was life changing for our family. Throughout this entire process, Matt has been incredibly generous with his time and knowledge. He patiently answered countless questions, explained reports in a way that made sense, and helped me understand what was actually happening inside our home when others minimized or dismissed it. He was calm, honest, and steady during an overwhelming situation. He also fogged all of our belongings and handled our items with care, professionalism, and respect. Knowing that our personal property was treated properly gave me peace of mind during a very stressful relocation. What sets Matt apart is not just his expertise, but his integrity and compassion. He genuinely cares about people’s health and safety, especially children, and it shows in every interaction. If you are dealing with mold, moisture issues, or indoor air quality concerns and want someone you can truly trust, Matt is the person to call.”
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.
