Your Local Waterproofing & Mold Remediation Experts in Los Angeles County
Living here in Southern California, we know the threats that moisture poses to our homes and buildings better than anyone. From the salt air rolling in off the Pacific along Santa Monica’s beachside streets, to the dry-heat cycles in Santa Clarita and Acton that crack stucco and open pathways for water intrusion — this region puts properties through conditions that other parts of the country simply don’t face.
That’s exactly why LA Waterproofer was built. Founded by Darren Elliot with a single mission — protect Southern California properties the right way — we’ve spent more than three decades showing homeowners, landlords, and commercial property managers in Hollywood, North Hollywood, Los Angeles, and beyond what true waterproofing and mold remediation look like when done by people who genuinely know the local climate, building codes, and construction styles.
Whether you’ve just spotted a dark patch on your Santa Monica condo ceiling, noticed a persistent musty smell in a North Hollywood rental unit, or you’re a contractor in Santa Clarita looking for a reliable remediation partner before a renovation — we’re the team that shows up, diagnoses correctly, and solves it for good.
Complete Mold & Waterproofing Services — All Under One Roof
We don’t just treat the symptom. We find where the water is coming from, eliminate any mold it has caused, and waterproof the structure so the problem doesn’t return. Every service we offer connects to that single goal.
Mold Detection & Inspection
Before any remediation begins, our technicians conduct a thorough mold inspection using moisture meters, thermal imaging, air quality sampling, and surface swab tests. We locate hidden mold behind walls, under floors, and in crawl spaces — the kind you can’t see but can certainly feel in your air quality. We serve Santa Monica, Hollywood, North Hollywood, Los Angeles, Santa Clarita, Acton, and surrounding communities.
Mold Remediation
Once detected, we contain the affected area, remove contaminated materials following IICRC S520 standards, apply EPA-approved antimicrobial treatments, and verify clearance through post-remediation testing. Our crews are active across Los Angeles County and respond promptly to both residential and commercial projects.
Waterproof Deck Coating
Elevated decks and rooftop terraces across Hollywood and Santa Monica are a constant source of water intrusion if not properly sealed. Our deck coating systems — applied to wood, concrete, and composite surfaces — provide a seamless, watertight barrier backed by years of SoCal performance.
Below Grade Waterproofing
Basements, underground garages, and below-grade walls in Los Angeles and Santa Clarita are highly vulnerable to hydrostatic pressure and soil moisture. We apply interior and exterior below-grade membrane systems that stop water at the source — before it reaches your foundation or interior slab.
Stucco Repair & Waterproofing
Stucco is everywhere in North Hollywood, Acton, and the San Fernando Valley — and when it cracks, it becomes a direct entry point for water and mold. We repair, re-coat, and seal stucco surfaces using breathable, elastomeric coatings that move with SoCal’s temperature swings.
Planter & Between-Slab Waterproofing
Planters embedded in decks or raised against exterior walls are notorious mold starters in Santa Monica and Malibu-adjacent properties. Our planter waterproofing systems — combined with between-slab treatments for multi-level properties — eliminate the trapped moisture that breeds mold season after season.
Why Los Angeles Properties Need Specialist Mold & Waterproofing Care
If you’ve owned property in the Los Angeles area for any length of time, you already understand that our climate doesn’t behave like most of the country. The marine layer that blankets Santa Monica and West Los Angeles throughout spring and summer creates persistent ambient humidity that seeps into buildings quietly — especially in older construction where vapor barriers were never installed. By the time you notice mold, it’s typically been colonizing for weeks or months.
In Hollywood and North Hollywood, we frequently encounter mold behind shower walls and under kitchen sinks in 1950s and 1960s apartment buildings where original plumbing has slowly wept moisture into wood framing for years. Landlords often discover the issue during a tenant turnover — and that’s where we come in. We provide rapid-response inspections and full remediation scopes so units can be turned around safely and legally.
Further inland in Santa Clarita and Acton, the problem shifts. Here, the dry summer heat expands and contracts stucco exteriors, creating hairline cracks that funnel the first autumn rains directly into wall cavities. We’ve remediated dozens of properties in these communities where a seemingly minor roof leak or cracked stucco section had gone unnoticed long enough to create significant black mold growth inside exterior walls.
The through-line in every case? Moisture that was never controlled at the source. That’s why our approach always combines mold remediation with waterproofing — because one without the other is an incomplete solution.

Frequently Asked Questions About Mold Remediation & Waterproofing in Los Angeles
Q: Does LA Waterproofer provide mold remediation services in Santa Monica and Hollywood?
A: Yes. LA Waterproofer provides full-service mold remediation and mold detection across Santa Monica, Hollywood, North Hollywood, Los Angeles, Santa Clarita, Acton, and surrounding communities in Los Angeles County. Our licensed technicians handle everything from the initial mold inspection and air quality testing through to full containment, material removal, antimicrobial treatment, and post-remediation clearance verification.
Q: What is the difference between mold detection and mold remediation?
A: Mold detection (or mold inspection) is the diagnostic process — identifying where mold is present using moisture meters, thermal imaging, air sampling, and surface swab testing. Mold remediation is the physical removal and treatment process: sealing off the contaminated area, removing affected materials, applying EPA-approved antimicrobial solutions, and restoring the space to a safe, mold-free condition. LA Waterproofer manages both services under one roof so you never have to coordinate between separate contractors.
Q: How do I know if I need mold remediation in my Los Angeles home?
A: The most common warning signs are a persistent musty or earthy odour, visible dark spots (black, green, or grey) on walls, ceilings, or around windows, unexplained respiratory symptoms or allergic reactions at home, water stains or discolouration, and any recent water damage or roof leak. Los Angeles and Santa Monica coastal properties are especially vulnerable due to marine layer humidity. If you observe any of these signs, contact us for a professional mold inspection — catching it early is always less costly than extensive remediation later.
Q: Can waterproofing actually prevent mold growth in my property?
A: Absolutely. Mold cannot grow without moisture. By professionally waterproofing the exterior surfaces, decks, planters, below-grade walls, and slabs of your property, you eliminate the moisture pathways that allow mold to take hold. Remediation alone without waterproofing is a temporary fix. Waterproofing alone after mold has already colonised doesn’t address the existing contamination. Together, they form a complete, long-lasting solution — which is exactly what we deliver across Hollywood, North Hollywood, Santa Clarita, and Greater Los Angeles.
Q: How long does mold remediation take in the Los Angeles area?
A: Most residential mold remediation projects in Los Angeles, Santa Monica, Hollywood, and North Hollywood are completed within 1 to 5 business days, depending on the size of the affected area, the extent of contamination, and whether structural materials need to be removed and replaced. Larger commercial properties or cases involving multiple units in Santa Clarita or Acton may take longer. We always provide a clear written timeline and project scope before work begins so you know exactly what to expect.
Q: Is LA Waterproofer licensed and insured for mold remediation in California?
A: Yes — fully. LA Waterproofer is licensed and insured to perform mold remediation, mold detection, and all waterproofing services throughout California, including all of Los Angeles County, Santa Monica, Hollywood, North Hollywood, Santa Clarita, and Acton. Our work complies with California Contractors State License Board (CSLB) regulations and IICRC S520 standards. With over 38 years of operating in this region, our track record speaks for itself.
