For landlords and tenants in a mold dispute
Independent, licensed mold assessments that document what is in the unit and where the moisture comes from, written so landlords, tenants and mediators can all rely on them.
A tenant finds mold on the bedroom wall and stops paying rent. A landlord believes the tenant kept the air conditioning off for weeks. Both are convinced, neither has evidence, and the texts are getting sharper. In Central Florida, where humidity and year-round cooling make moisture problems common, this dispute plays out constantly.
UES is an independent, Florida DBPR licensed mold assessment company serving Orlando and Central Florida since 2000. We never remediate and we take no referral fees from contractors, so our only job is to document what is actually happening in the unit. Whether you own the property or live in it, you receive the same neutral report, written so a landlord, a tenant, a mediator or a judge can read it.
A dark stain could be mold or soot, from a leak or from condensation. Without moisture readings and lab analysis, each side reads the picture to suit its case.
Landlords point to showers without the fan, furniture against exterior walls and AC left off. Tenants point to leaks and ignored repair requests. Often the truth involves both.
Tenants fear for their families. Landlords want to know whether the concern is justified before moving someone out or opening a wall.
A remediator who inspects for free and then quotes thousands in work is not a neutral witness, and the other party will say so.
Florida landlords carry a duty to keep rental housing habitable, and mold complaints land squarely in that territory. The fastest way to protect yourself is also the fairest: get a licensed, neutral assessment promptly and act on it. If the unit is dry and the sampling shows normal fungal ecology, you have documentation that answers the complaint. If there is a leak or a building defect, you learn about it before it spreads to the next unit or the next tenant.
UES reports describe the moisture source without spin. When the evidence shows an occupant condition, such as disabled cooling or blocked ventilation, we say so and show the readings. When the evidence shows a building failure, we say that too. Either way, you have a dated record created by a licensed third party with no stake in the outcome.
We do not provide legal advice. For questions about notices, rent or remedies, consult an attorney.
If you are living with suspected mold, you need to know two things: whether it is actually there, and whether the building is causing it. A UES assessment answers both. Our assessor measures moisture, uses thermal imaging to find hidden wet areas and collects samples for independent lab analysis.
You receive the report, the lab results and, if growth is found, a protocol describing what has to be done. This is the documentation that supports a repair request to your landlord, and because UES does not remediate, nobody can claim the findings were exaggerated to sell a service. We will also tell you honestly if the conditions trace to something within your control, like humidity or ventilation, so you can fix it.
If you have health concerns, speak with a physician. UES assesses buildings, not people.
Either party may order the assessment, and with permission the findings can be shared through the UES Client Portal so both sides read the same document. Most disputes resolve once the moisture source is identified and the scope is defined, because the argument shifts from blame to a concrete repair. Where the matter proceeds to mediation or court, the report, lab data and chain-of-custody records are prepared to be relied upon.
Both parties can also use the written protocol as a checklist: the landlord knows what work has to be done, the tenant knows what to expect, and post-remediation verification confirms when the unit is ready. If you are unsure whether to order a limited assessment of one room or a full assessment of the whole unit, call (407) 438-4684 and describe the situation.
Either party may. The assessment and the report are the same regardless of who pays, and the findings can be shared with the other side through the UES Client Portal.
The report documents the moisture source and the conditions observed. It states whether the water came from a leak, plumbing, the AC system or indoor humidity. Legal responsibility is a separate question for the parties or their attorneys.
No. UES is an assessment company only. We never perform remediation and accept no referral fees. When growth is found, we provide a protocol and a list of vetted licensed Florida remediators, and we can return afterward to verify the work.
Most rental unit assessments are completed in a single visit. Lab results follow within the turnaround we quote before booking. Call (407) 438-4684 to discuss timing.
Our reports, photographs, lab results and chain-of-custody documentation are prepared to be relied upon. If your matter requires testimony, contact us. UES does not provide legal advice.
Fast scheduling, defensible documentation and no remediation upsell. Call (407) 438-4684 or book online.
“The owner and her team are incredibly thorough. They spent hours in my home and shared what they were doing along the way. UES goes way beyond what I expected, providing an education along with a comprehensive analysis. A multipage report along with recommendations was professionally presented and staff was available to answer all of my questions. I have complete faith in UES's procedures and findings and highly recommend them with no reservations.”
“No home owner wants to hear the word "mold", but if you do, you need the best to support you through the journey. Ultimate Environmental Solutions (UES) is the best. Initially, I didn't know where to turn and UES was highly recommended to me by a friend. The owner and her team walked me through every step and created a plan of action. They were kind, responsive, professional, but most of all knowledgeable. The thorough protocol report they provided was a valuable asset in claiming mold and water damage compensation from my insurance company. Do not cut corners when it comes to mold. The owner is an expert in her field. She is my trusted ally and truly went above and beyond.”
“If you are wondering who to trust with the health and safety of your family, look no further than UES Ultimate Environmental Solutions, Inc. The owner came out to our home and put my mind and wallet to ease. She was transparent, authentic, and professional. She truly cared about my family and our needs, including financial and wellbeing. It's hard to trust anyone anymore. I promise you; you can trust UES. Once you meet her, you'll immediately know why I felt compelled to leave this review as soon as she left my home. Thank you for UES.”
“Ultimate Environmental Solutions provided the environmental testing during a remediation project due to hurricane damage to one of my commercial office building. I found UES to be very professional and easy to work with. I will definitely reach out to them should the need arise.”
“My experience with UES was wonderful. The inspector was friendly, professional and thorough. The office staff was very competent and helpful. The mold specialists spent a great deal of time with me on the phone assessing my needs and guiding me to the type of inspection that was right for me, and she was very careful and thorough in explaining to me the results of the lab results. I HIGHLY RECOMMEND this company to anyone searching for mold inspections.”
“Unbelievable customer service and professional knowledge even to non-customer!!! Right off the bat, the owner knew her FL company couldn't help my out-of-state situation; yet she spent her time offering me direction, tips, pointers, pointing me to national testing lab and national organizations which may be able to provide environmental test kit and consultants in my state to help me with the vapor invasion situation at my town home. She even helped me understand a bit on everything from typical airflow of building, firewall building code, construction layout of high density residence... The information she gave me will save me hours of researching. A true rarity.”
“Prompt, thorough and efficient. Did an in-depth survey and report of findings, after our recent fire. Not someone I want to see, again, LOL. But, would highly recommend their services.”
“The UES team were honest, thorough and experts in their forensic analysis of my home environmental inspection. I highly recommend them for anyone concerned with potential mold issues in their home.”
“The owner and her team were very thorough and very knowledgeable. We've been dealing with them for a couple years now. Look no further for mold experts.”
“I highly recommend this company. I used their services on two separate occasions. The owner is awesome. The report was very comprehensive but she still took the time to review it with me by phone to ensure I had all the necessary information. The team are experts in what they do. I found them to be very knowledgeable, punctual and pleasant to work with.”
