Remediation is not finished until someone independent proves it.
Post-Remediation Verification
Independent clearance inspection and sampling after mold remediation, performed by licensed assessors who had no part in the removal work.
A remediation contractor telling you the job is done is an opinion. A clearance report from a licensed assessor who did not perform the work is evidence. Post-remediation verification, often called PRV or clearance testing, is the independent inspection and sampling that confirms mold-affected materials were removed, the work area was properly cleaned and the space has returned to a normal fungal ecology before walls are closed and the containment comes down.
Florida licenses mold assessors and mold remediators as separate professions and keeps the two roles apart on the same project. That structure exists to protect you. UES is a Florida DBPR licensed assessment firm that has never performed remediation, so our clearance decision is based only on what we see and what the accredited laboratory reports.
When clearance testing is the right call
- A remediation contractor has finished removal in your home and you want proof before you pay the final invoice and rebuild.
- Your insurer, lender, buyer or landlord requires written clearance documentation from a licensed assessor.
- You are a property manager or HOA closing out a water loss and need a defensible record for owners and tenants.
- A previous remediation failed and you want independent confirmation this time before trusting the result.
- You are selling a home with a disclosed mold history and want a clean clearance report to share with buyers.
- You hired UES for the initial assessment and want the same team to verify the protocol was followed.
How it works
- 1
Schedule the verification while containment and air scrubbers are still in place; clearance should happen before any reconstruction begins.
- 2
A licensed assessor visually inspects the work area for remaining growth, residual dust, moisture and compliance with the written remediation protocol.
- 3
Moisture readings confirm that affected materials are dry and that the original water source has been corrected.
- 4
Air samples inside the containment are collected alongside outdoor and unaffected indoor controls, with surface samples where appropriate, and sent under chain of custody to an accredited laboratory.
- 5
If the data and inspection meet clearance criteria, we issue a written verification report in the UES Client Portal. If not, we identify exactly what must be corrected before retesting.
What a passing clearance actually requires
Clearance is not a single number. It is a judgment that rests on three legs, and all three must hold. First, a visual pass: no visible growth, no water staining on remaining materials, no settled dust on surfaces inside the containment, and all materials listed for removal in the protocol actually gone. Second, moisture: the building materials that remain must be dry and the source of water must be verified as repaired. Third, laboratory data: indoor spore types and concentrations should be consistent with, or lower than, the outdoor control and unaffected areas of the building, with no indicator species dominating.
A room can pass the air sample and still fail clearance because wet framing was left in place or because the contractor removed less drywall than the protocol specified. Likewise, a spotless room may fail the air sample because the air scrubbers were shut off early and settled spores were disturbed. UES evaluates all three together and tells you plainly which element, if any, fell short.
Why the assessor must be independent of the remediator
When the same company removes mold and then declares its own work clean, the test is a formality. Florida separates the two licenses so that someone with no stake in the outcome makes the call. UES takes this a step further. We do not remediate, we do not refer work for a fee, and we do not partner with contractors on a job. The remediator's only path to a passing report is to do the work correctly.
That independence protects everyone. Homeowners avoid paying for incomplete work and discovering it when the problem returns. Insurers and lenders receive documentation they can rely on. Honest contractors benefit too, because a third-party clearance report backs up their invoice and settles disputes before they start. If a contractor resists independent verification or insists on using its own tester, treat that as useful information.
Timing, scheduling and what can go wrong
The most common clearance failure we see is reconstruction that started too early. Once new drywall is up, the assessor cannot verify what was removed or whether framing is dry. Schedule PRV before the containment comes down and while air filtration devices are still running, then shut the scrubbers off for the period the laboratory requires before air sampling so the test reflects real conditions.
- Keep the containment, negative air and plastic barriers in place until clearance is issued.
- Have the contractor provide the written protocol, moisture logs and photographs of the work.
- Confirm the water source repair is complete and documented, not just scheduled.
- Allow time for laboratory turnaround before committing to a rebuild start date.
- If the test fails, the contractor returns to correct the deficiencies and we retest the affected areas only.
Clearance for Florida insurance claims and real estate
In Florida, mold clearance documentation is routinely requested by insurance adjusters closing a water damage claim, by lenders before funding a purchase or refinance, by buyers who learned of a remediation during disclosure and by landlords who need to show a unit was returned to habitable condition. A UES verification report includes the visual findings, moisture data, laboratory results with chain of custody, photographs and a clear clearance statement signed by a licensed assessor. Clients who used UES for the original assessment can track the remediator's progress against our protocol item by item in the Remediation Tracker, which makes the final verification faster and leaves a complete record from first inspection to clearance. Keep that report with your property records; it answers the question the next buyer, adjuster or tenant will inevitably ask.
Clearance Testing questions
When should post-remediation verification be scheduled?
Immediately after the remediator finishes removal and cleaning, before containment is removed and before any rebuilding begins. The work area should still be isolated, dry and cleaned, with the water source repaired. We coordinate directly with your contractor so the timing works.
Can the remediation company do its own clearance test?
Florida law keeps the mold assessor and mold remediator roles separate on a project, and for good reason. A clearance report from the company that did the work is not independent and is often not accepted by insurers, lenders or buyers. Hire a licensed assessor with no connection to the contractor.
What happens if the clearance test fails?
You receive a report identifying what fell short, whether that is remaining growth, elevated moisture, residual dust or laboratory results that do not match the controls. The remediator corrects the deficiencies under the original scope, and we return to retest only the areas that failed.
Do I need PRV if UES did not do the original assessment?
No. We regularly perform clearance testing on projects assessed by other firms or on remediations done without any prior protocol. We will ask for whatever documentation exists and establish the inspection and sampling plan from there.
How do I schedule clearance testing in Orlando?
Book at /book-assessment or call (407) 438-4684 as soon as your contractor gives you a completion date. We serve Orlando, Leesburg, Kissimmee, Sanford and the rest of Central Florida, and we can often coordinate the visit for the day the remediation wraps up.

“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.

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.”

I found them to be very knowledgeable, punctual and pleasant to work with.”
