Every Car Assessed First
Servicing Washington Since 2014
30-Day Return Warranty
Persistent damp weather and infrequent drying days make Seattle one of the easiest climates for cabin mold.
Where mold takes hold
Mold hides in the places a wipe-down misses — deep in the padding, the seams, and the HVAC core.
Now we build the plan
Every car is different, so we match the method to the damage — steam, padding replacement, or light enzyme treatment, zone by zone.
Cersei OS — Remediation Plan
Every mold job is different. So is our plan.
Mold is not a one-size fix. Scrub through the plan to see how we tailor the method to each zone — steam, padding replacement, or light enzyme treatment.
01 / Assess
Read the car, not a script
We inspect every zone — carpet, padding, seat foam, headliner, and the HVAC core — and grade how far the moisture and mold actually spread. No two cars get the same plan.

02 / Match method
Match the method to the damage
Light surface mold is steam-sanitized in place. Where it went deeper we lift the carpet — and on the worst cars we pull the seats and replace saturated padding outright.
03 / Neutralize
Break it down with enzymes
Affected materials get an EPA anti-microbial and light enzyme treatment that breaks the mold down at the source and keeps it from coming back.
04 / Dry out
Pull the moisture, then let it breathe
We extract the moisture that fed the mold. Tougher jobs finish drying overnight with the windows cracked and ventilated, so nothing is left damp under the surface.
05 / Protect
Sealed and backed by warranty
A final anti-microbial pass leaves the cabin treated and deodorized — backed by our 30-day return warranty.
Pricing is based on mold severity: Our packages are designed for different levels of mold contamination. The more extensive the mold growth and moisture damage, the higher package tier you'll need for complete remediation. Most cabin mold is treatable when moisture is addressed — we confirm on inspection before work starts.
Our 30-day warranty depends on selecting the right package: To ensure satisfaction, it's essential to choose the package that matches your vehicle's current condition. If you're unsure which package is right for you, please call or text us at (833) 892-8886 and we'll help you select the best option. Many policies cover mold after a covered water event — we can provide documentation for your claim; coverage still depends on your policy.

Our Professional Treatment Process
A comprehensive 6-step mold and mildew remediation process designed to eliminate mold/mildew and prevent its return.
Thorough Inspection
Complete visual assessment to identify all mold colonies, moisture sources, and affected areas including hidden spots. We document everything to create a tailored treatment plan.
Vacuum & Prep
Remove loose mold spores and debris with professional HEPA filtration equipment, then prep the vehicle for deep treatment. This prevents spore spread during cleaning.
Treat the Right Way
Based on what we find, we match the method to the damage: steam-sanitize surfaces in place, lift the carpet to reach beneath it, or remove seats and replace saturated padding on the worst cars. No two plans are identical.
Disinfect Affected Areas
Apply industrial-grade anti-microbial solutions and light enzyme treatments to break down mold spores and prevent regrowth. Our EPA-approved products are safe yet highly effective.
Moisture Extraction & Dry-Down
Extract the moisture that fed the mold from carpets, padding, and upholstery. On tougher jobs the car finishes drying overnight with the windows cracked and ventilated, so nothing is left damp under the surface.
Getting to the Source
Identify and address the root cause of mold growth, including leaks, moisture intrusion points, and ventilation issues to prevent future problems. We provide recommendations for long-term prevention.
Field Evidence — 0.1
Experience decides the method
There's no single fix for mold. On lighter cars we steam-sanitize surfaces in place; when it's gone deeper we lift the carpet, and on the worst cars we pull the seats and replace saturated padding. Every job finishes with an enzyme and anti-microbial treatment — and the tough ones dry overnight with the windows ventilated. Toggle to Details for the full remediation spec.
