Looking for a mold remediation or removal company in Puerto Rico? You're in the right place. Below you'll find our directory of independent mold remediation companies serving the territory, organized by city and municipio so you can reach a local crew quickly. First, this short overview explains why mold is so common across Puerto Rico, how the trade is (and isn't) regulated here, which certifications and standards actually matter, and how to choose a contractor with confidence.
Browse mold remediation and removal companies by city and municipio across Puerto Rico—from San Juan, Bayamón, and Carolina to Ponce, Mayagüez, and Caguas.
Not sure where to begin? We suggest starting with an independent mold inspection so you understand the size and cause of the problem before you hire anyone to remove it.
We publish this directory purely as a courtesy to Puerto Rico homeowners, renters, and property managers. Mold Inspection & Testing (MI&T) is an inspection-and-testing-only company: we do not perform remediation and we do not sell mold removal. Every company listed here is an independent contractor, not affiliated with us, so you can weigh your options freely.
Puerto Rico's climate is essentially a greenhouse for mold. According to the NOAA State Climate Summary for Puerto Rico and the U.S. Virgin Islands, the territory averages about 81°F year-round and roughly 64 inches of rain a year, with warm, humid tropical conditions from coast to coast. Rainfall is even more dramatic in the interior: the El Yunque National Forest receives more than 200 inches annually, making it one of the wettest places anywhere under the U.S. flag, while the drier southern coast around Ponce still sees close to 40 inches. Add near-constant humidity and warm nights—which NOAA notes have been running above average—and indoor surfaces rarely get a chance to fully dry out.
Hurricanes turn that steady moisture pressure into acute crises. When a storm drives rain and floodwater into a building, mold can begin colonizing damp drywall, wood, and furnishings within a day or two in this heat. Just as damaging is what happens after the wind stops: prolonged power outages shut off the air conditioning and dehumidifiers that normally hold indoor humidity down. After Hurricane Maria struck as a Category 4 in 2017—causing an estimated $90 billion in damage and the longest, most severe power outage in American history—researchers documented elevated indoor mold levels in flood-affected Puerto Rico homes. Communities from San Juan to the mountain municipios lived that reality for months.
The territory's housing stock adds to the challenge. Concrete-and-block construction, flat roofs prone to ponding, window-unit air conditioning, and additions built over time can all trap humidity or admit water intrusion. In a marine tropical climate, even a small unaddressed leak, a chronically damp bathroom, or a stretch without working AC can seed a mold problem that spreads quickly.
As of August 2026, Puerto Rico does not issue a territory-specific license or registration for mold remediation contractors or mold assessors. Unlike a handful of U.S. states that license the trade, there is no dedicated Puerto Rico mold license, mold-assessor credential, or associated fee schedule to look up—so you cannot simply ask to see a “mold license” the way you might elsewhere. That makes your own screening the real safeguard.
The absence of a local license does not mean anything goes. U.S. Environmental Protection Agency mold guidance still applies in Puerto Rico, and reputable contractors work to nationally recognized standards. In place of a license, screen for voluntary certification (such as IICRC or NORMI), proof of general liability insurance, verifiable references, and a written commitment to follow the ANSI/IICRC S520 standard and EPA remediation guidance. Those markers tell you far more about competence than any single credential would.
Puerto Rico has no mold-specific statute and no mold disclosure requirement. Instead, the rights and duties around a moldy rental flow from the general lease provisions of the Puerto Rico Civil Code. Under those rules, a lessor must deliver the property fit for its intended use and make the repairs necessary to keep it that way, while a tenant is expected to report problems promptly and avoid causing damage. Because indoor mold almost always traces back to an underlying moisture source—a roof leak, plumbing failure, or unrepaired storm damage—these repair-and-habitability duties are usually the relevant framework.
If you're a renter dealing with mold, documenting the condition with an independent inspection creates an objective record of what's present and what's likely causing it, which is useful whether you're requesting repairs or resolving a dispute. This is general educational information and not legal advice; for how the Civil Code applies to your specific lease, consult the Code itself and a qualified Puerto Rico attorney.
Because Puerto Rico doesn't license the trade, the standards a contractor voluntarily follows carry extra weight. Look for these:
Since there's no territory mold license, ask for current certification from a recognized body such as the IICRC or NORMI, and confirm the technicians who will actually be on your job are trained. Certification isn't a legal requirement here, but it signals the contractor has invested in doing the work correctly.
When the same company both tests for mold and sells the removal, there's a built-in incentive to find more work than you need. Keeping the two roles separate—an independent inspection up front and an independent clearance test at the end—gives you an unbiased scope and objective proof the job worked.

Get a detailed, written scope before work begins: what areas are affected, how the crew will contain and remove the mold, how they'll dry the structure, and how success will be verified. This matters especially after Puerto Rico's real failure modes—post-hurricane water intrusion and long stretches without AC or dehumidification, where hidden moisture behind walls and under floors is easy to miss. A vague verbal promise is not enough.
Ask for proof of general liability insurance and, where applicable, workers' compensation, and request references from recent local jobs. A contractor who has cleaned up mold after Caribbean storms in your area should be able to point to that work.
Collect at least two or three written estimates so you can compare scope, methods, and price. Wide gaps in what contractors propose are a signal to ask more questions—an independent inspection report gives every bidder the same facts to quote against.

Puerto Rico has a warm, humid tropical climate with an annual average temperature near 81°F and heavy rainfall—about 64 inches a year territory-wide and more than 200 inches a year in the El Yunque rainforest, among the wettest places under the U.S. flag. Constant humidity, frequent rain, and hurricane-driven flooding give mold the moisture it needs to grow indoors year-round.
Yes. Hurricanes push water into buildings, and prolonged power outages shut down the air conditioning and dehumidifiers that normally keep indoor humidity in check. After Hurricane Maria in 2017, Puerto Rico endured the longest blackout in U.S. history, and researchers documented elevated indoor mold levels in flood-affected homes. In the tropics, mold can take hold within a day or two of water intrusion.
Puerto Rico has no mold-specific statute or mold disclosure requirement. Instead, the Puerto Rico Civil Code governs leases: a lessor must deliver the property fit for its intended use and make the repairs needed to keep it that way, while tenants must report problems and avoid causing damage.

We recommend keeping them separate. When one company both tests for mold and sells the removal, it has a built-in incentive to find more work. An independent inspection and post-remediation clearance test—ideally analyzed by an AIHA-accredited laboratory—gives you an unbiased scope up front and objective proof the job was done right.
