Mold Inspection & Air Quality Testing in Marion County, FL

Marion County is a straight run north on US 27 and US 441 from Leesburg, and Ocala is roughly forty-five minutes from our office. We assess homes, horse farms, retirement communities and commercial buildings from Belleview and Summerfield to Dunnellon and the Ocala National Forest.

Independent mold assessors for all of Marion County

Marion County's rolling horse country sits on porous limestone that feeds Silver Springs and Rainbow Springs, and that same geology brings high groundwater, sinkholes and damp slabs to the neighborhoods around them. Ocala's historic district holds early twentieth century frame homes with crawl spaces, while Silver Springs Shores, Marion Oaks and the On Top of the World and Stone Creek retirement communities span decades of block construction. Growth around the World Equestrian Center and the SR 200 corridor has added thousands of tight new homes with condensation complaints. Along the Ocklawaha River and in the Ocala National Forest communities of Salt Springs and Fort McCoy, manufactured homes and well-fed cabins face persistent humidity and roof leaks. Barns and tack rooms add their own moisture and odor questions.

Every Marion County assessment follows the UES Protocol: forensic visual inspection, moisture source detection with thermal imaging and moisture meters, air and surface sampling analyzed by an independent accredited laboratory under chain of custody, and a written remediation protocol delivered in your UES Client Portal. Because we never remediate, the findings serve only you.

Inspection or test? What each one answers

Many Marion County callers ask for “a mold test.” A laboratory sample is one tool inside an assessment, and on its own it cannot find the water source or tell you what to fix. This is how the pieces fit together.

The questionWhat answers itWhat cannot
Is there a moisture problem, and where?Inspection: moisture meters, thermal imaging, visual forensicsA lab result alone
Is there hidden mold behind a wall or in the air handler?Inspection plus targeted air or cavity samplingA single room air test

How we find moisture you cannot see

Mold is a moisture problem first. In Marion County we routinely trace it to condensation at supply registers and in air handler closets, slow plumbing leaks inside block walls, window and door flashing failures, roof and lanai transitions, and humidity that stays high while a seasonal home sits closed. Thermal imaging shows temperature patterns that betray wet material; pin and pinless moisture meters confirm it; psychrometric readings tell us whether the air conditioning is actually dehumidifying. Only then do we decide where a sample is worth taking.

Marion County mold inspection questions

Does UES assess barns, tack rooms and farm outbuildings in Marion County horse country?

Yes. We regularly assess residences on equestrian properties and can include barns, apartments over barns, offices and climate-controlled tack or feed rooms in the same visit. Hay dust, animal dander and open-air moisture create a different sampling picture than a sealed home, and we interpret results with that in mind.

Is Ocala far enough from Leesburg that I will pay a travel charge?

Ocala, Belleview and Summerfield are part of our regular service territory and are scheduled like any Central Florida address. Our assessors travel US 27 and US 441 into Marion County several times a week, and we can usually offer a date within the same week. Call (407) 438-4684 for availability in Dunnellon, Salt Springs or other outlying areas.

We are buying in On Top of the World or Stone Creek. Should we test before closing?

A pre-purchase mold assessment is a smart step in any retirement community where the seller may have been a part-time resident. Closed-up homes with thermostats set high can develop humidity-driven growth in closets, under sinks and inside the air handler without any visible water event. We provide an unbiased report because UES does not perform remediation and has no stake in what the findings show.

Does UES perform mold removal in Marion County?

No. UES is an independent assessment company. We test, diagnose and write the remediation protocol, then verify the work afterwards. We never perform remediation, so our findings serve only you.

How do I verify a mold assessor's license in Marion County?

Search the business or license number on the Florida DBPR license portal. Mold assessor licenses begin with MRSA; remediator licenses begin with MRSR. Florida licenses the two roles separately, which is why an assessor with no remediation business is the independent choice.

  1. 01Forensic Visual Inspection

    Our state-licensed consultant begins where a simple inspection ends. We conduct a thorough forensic investigation of your property, documenting its history, identifying potential moisture intrusion points, and assessing ventilation systems. We look for the subtle warning signs that unqualified inspectors often miss.

  2. 02Advanced Microbial Sampling & Lab Analysis

    Based on our initial findings, we use industry-leading tools to collect strategic air and surface samples. These are sent under strict chain of custody to an independent, accredited laboratory. The analysis identifies the precise species and concentration of mold spores present, giving us the hard data needed to assess the health risk.

  3. 03Moisture Source Detection

    This is the step that separates a temporary fix from a permanent solution. Mold cannot exist without moisture. Using thermal imaging cameras and moisture meters, we pinpoint the hidden water source fueling the growth, whether it's a slow pipe leak, a condensation issue, or a compromised building envelope. We don't just find the mold; we find the cause.

  4. 04Written Protocol & Client Portal Delivery

    You receive a clear, step-by-step remediation protocol and interactive findings in the UES Client Portal, along with a vetted list of local remediators. Share the protocol with contractors, get accurate quotes and track the work item by item.

  5. 05Post-Remediation Verification

    Once remediation is complete, we return to inspect and sample again. Clearance is issued only when the data confirms the work was done right, so you can rebuild and move back in with confidence.

What our clients say

“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.”

Sara RothfederGoogle review · Jul 2026

“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.”

Sheri RichardsonGoogle review · 2021

“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.”

Mary DillardGoogle review · 2025 · Commercial property owner

“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.”

Patricia McCallGoogle review · 2022

“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.”

Cole KoonGoogle review · Feb 2026

“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.”
