The Thompson DifferenceMost attorneys treat mold cases as a sideline. Anthony Thompson has made it his entire career.
At Thompson Injury Law, we’ve made a bold commitment that sets us apart from every other law firm in Southern California: We are the ONLY firm that exclusively handles toxic mold claims. While other attorneys juggle dozens of practice areas, we’ve dedicated our entire legal practice to mastering the complex science, medicine, and law surrounding toxic mold exposure.
Since our establishment in San Diego in 1976, we’ve evolved from a general personal injury firm to become Southern California’s premier toxic mold litigation specialists. This exclusive focus means when you hire Thompson Injury Law, you’re getting attorneys who work on mold cases day in and day out.
We handle nothing but toxic mold.
Anthony Thompson’s caseload is 100% mold, 100% of the time. That is not a marketing claim — it is a verifiable fact about how this firm operates. Specialized focus means deeper relationships with the building science and medical experts who win mold cases, and an institutional knowledge of defense tactics that generalist attorneys simply do not have.
We know the science. Not just the law.
Mold cases are won or lost on building science, mycology, and medical causation — not legal procedure. Anthony Thompson has studied more environmental literature on toxic mold than most treating physicians have. He knows when a defense-hired industrial hygienist is misrepresenting spore counts, and he knows how to challenge it on cross-examination.
Nearly 50 years of relationships with the experts who matter.
The doctors, industrial hygienists, and building forensics experts who provide credible testimony in mold litigation are a small community. After nearly five decades in Southern California environmental law, Thompson Injury Law has working relationships with the region’s most respected independent experts — not the same hired-gun witnesses that appear for every defendant.
You pay nothing in fees unless we win. No retainer. No hourly fees.
Our contingency fee arrangement means you never receive a bill for our work. If we do not recover for you, you owe us nothing in attorney fees. For working families dealing with the financial stress of displacement, medical bills, and property damage, this is not a small thing. It is the reason you can afford to fight back regardless of your income.
We have seen every defense tactic your landlord's insurance company will use — and we know how to beat them.
Insurance carriers defending mold claims use a predictable playbook: dispute causation, challenge the testing methodology, minimize health impacts, delay. Because Thompson Injury Law handles only mold cases, we have seen this playbook dozens of times. We anticipate it. We prepare for it. And we have the case outcomes to show it.
California law requires every rental unit to be habitable from move-in to move-out. When a landlord fails to repair a leak, ignores your written complaints about visible mold, or retaliates against you for filing a complaint with the housing department, they are violating that duty. Thompson Injury Law has represented hundreds of tenants in exactly this situation — many from immigrant communities and lower-income neighborhoods where slumlords calculate that tenants will not fight back. We exist to prove that calculation wrong.
Homeowners associations have a legal duty to maintain common areas and building systems that protect individual units. When an HOA board defers a roof repair, ignores a known drainage problem, or fails to remediate mold discovered during an inspection, unit owners suffer the health and financial consequences. These cases are complex — they involve CC&Rs, insurance coverage disputes, and board meeting records — and they require an attorney who has litigated them before. We have.
Developers, builders, and contractors are required to build to code and meet the standard of care in their industry. When defective construction allows water intrusion that leads to toxic mold growth, the builder — not you — should bear the cost of remediation, displacement, and health consequences. These cases often involve multiple defendants (developer, general contractor, subcontractors, architects) and require building forensics experts who can trace the water pathway. This is work Thompson Injury Law does on every relevant case.

These clients came to Thompson Injury Law facing many of the same challenges you may be facing now—landlords denying responsibility, insurers minimizing the problem, and uncertainty about what to do next. Their experiences reflect the focused advocacy, specialized knowledge, and commitment that have made Thompson Injury Law Southern California’s only mold-exclusive law firm.
Anthony Thompson has spent his career doing one thing: representing people whose health and homes were damaged by toxic mold, and holding the property owners, builders, and insurers responsible for the harm they caused. For nearly five decades, Thompson Injury Law has been the firm those clients call in Southern California.
He has been recognized as a Super Lawyers honoree for eight consecutive years — an honor based on peer recognition and professional achievement, not advertising. More importantly, his clients recover. The settlement and verdict outcomes on his bio page are not cherry-picked highlights — they represent the consistent pattern of results that comes from doing this work exclusively.
How much does it cost to hire Thompson Injury Law?
No attorney fees upfront, and no attorney fees unless we win. We work on a contingency fee arrangement, which means we only get paid attorney fees if we recover money for you. There is no retainer, no hourly billing, and no cost for the initial consultation. If your case does not result in a recovery, you owe us nothing in fees. This is how we make it possible for any mold victim — regardless of income — to access experienced legal representation.
How long does a mold lawsuit typically take?
Most toxic mold cases in Southern California resolve within 12 to 36 months. Cases that settle before trial are typically faster; cases involving large defendants, disputed causation, or multiple parties may take longer. During your free consultation, we will give you a realistic timeline assessment based on the specific facts of your case, who the defendant is, and how contested the liability is likely to be.
What is my mold case worth?
It depends on the severity of your health symptoms, the duration of exposure, the cost of remediation and any relocation, your lost income, and the strength of the evidence against the responsible party. In our experience, straightforward landlord-tenant mold cases settle in the range of $50,000 to $300,000. We will give you an honest range during the consultation — not a number designed to get you to sign a contract.
Do I need a mold test result to have a case?
Not necessarily, but it helps significantly. Visible mold, photographs, written complaints to the landlord, and documented health symptoms can all establish a viable claim even without formal mold testing. That said, we typically recommend getting a professional mold test as early as possible — both to document the problem and to preserve evidence before any remediation disturbs it. We can refer you to qualified independent industrial hygienists in Southern California.
My landlord says the mold is my fault. What are my options?
This is one of the most common defenses in landlord-tenant mold cases, and it is often wrong. California courts look at whose responsibility it was to maintain the building systems that allowed moisture intrusion — usually the landlord. If the mold resulted from a roof leak, plumbing failure, foundation crack, or HVAC problem, those are the landlord’s systems to maintain. We will review your lease, the property’s maintenance history, and the source of the water intrusion to establish who bears responsibility.
Can my landlord evict me for making a mold complaint or filing a lawsuit?
No. California law prohibits landlords from retaliating against tenants who report habitability problems to housing authorities, complain to the landlord in writing, or exercise their legal rights. If a landlord raises your rent, files an eviction notice, or reduces services within 180 days of a protected complaint, California courts presume that action is retaliatory. We can advise you on protecting yourself from retaliation as part of your case.
What if my insurance company already denied my mold claim?
An insurer’s denial of your mold claim is not the end of the road — it may actually be the beginning of a bad faith insurance case. California imposes strict duties on insurers to investigate claims thoroughly and not deny valid claims without reasonable cause. We review insurance denials as part of our intake process. Depending on the policy language and the grounds for denial, you may have claims against both the property owner and the insurer.
