At Dry Effect, we test your property for mold and air quality. After mold testing, we provide you with our recommended course of action to improve your indoor air.



We serve a variety of different clients – both residential and commercial. Our team consists of certified professionals with years of experience and an owner who has been serving the public in the fields of environment and health safety.

Our focus is determining the existence of indoor mold growth, type of mold, and the airborne mold spore concentration (we want to know what you and your family are breathing). Primary types of lab samples that we recommend to test for mold:

  1. Ambient airborne mold spore samples (air in the breathing space of a room),
  2. Surface (direct) samples (swab, bulk materials, tape lift)

Cincinnati Mold Inspection and Mold Detection Services

Complete mold investigation of your home, rental property, school, or business designed to identify sources and instances of moisture intrusion and to detect mold,

Our findings, conclusions, and recommendations, are assembled into a complete, written report,

We use the best moisture detection instruments, digital hygrometers, and Zefon Bio-Pumps® and Zefon Air-O-Cells® (for airborne mold spore samples).

mold testing



  1. Collect a specific amount of air in a chosen indoor living area and compare the types and amounts of fungal spores detected to the air collected outside of the home.


  1. Less expensive than viable sampling.


  1. Non-viable: Identification of fungal organism groups only. No species identification.
  2. Results represent fungal spores detected in the tested area during the collection period only.
  3. Sample area is limited to approximately 100 SF of open space.
  4. Fungal spores may exist on surfaces without being released into the air.


  1. All occupants / owners upon completion of remediation process to ensure spores in the air are at or below the outdoor environment (clearance).
  2. To mostly healthy occupants / owners, if living areas have visible signs of current or previous water damage or repairs.
  3. Mostly healthy home buyers, if home purchase disclosures indicate previous water intrusion or repair work.




  1. Collect a surface sample in each area with potential mold growth or visible residue.


  1. Less expensive than viable sampling.


  1. Non-viable: Identification of fungal organism groups only. No species identification.
  2. Results represent area sampled only.
  3. Elevated levels of fungal spores may still exist in the air even after treating visible mold on surfaces.


  1. To all occupants / owners in living areas with visible signs of discoloration, residue or elevated moisture levels.


Cincinnati Mold Remediation: Protocols and Post Testing Services

If the mold inspection and mold testing of your property detects a mold problem, we can write a Mold Remediation Protocol (“scope of work”) that provides detailed instructions to follow when doing the Mold Remediation.

Once the mold has been completely and properly remediated, Dry Effect will perform a Post Mold Remediation Clearance Inspection and Testing to ensure that the job has been done right! We are your protection! Don’t be fooled by other remediation specialist whom don’t test after they’ve remediated. If you can visibly see it with the naked eye, how can they verify they’ve been successful with the remediation.

Why Post Verification Remediation Testing is Important?

At Dry Effect, our job and our responsibility during the Post Mold Remediation phase of a project is to ensure our clients that their mold remediation job has been completed correctly. One of our microbial consultants will perform the final check on your mold remediation project.  Once we deem the project complete and successful, we will sign a Mold Clearance Certificate for the client.


Clearance criteria.

For a remediation project to achieve clearance, a licensed mold assessment consultant shall conduct a post-remediation assessment using visual, procedural, and analytical methods. If walk-in containment is used during remediation, the post-remediation assessment shall be conducted while the walk-in containment is in place. The post-remediation assessment shall determine whether:

  1. the work area is free from all visible mold and wood rot; and,
  2. all work has been completed in compliance with the remediation protocol and remediation work plan and meets clearance criteria specified in the protocol.

Underlying cause of mold.

Post-remediation assessment shall, to the extent feasible, determine that the underlying cause of the mold has been remediated so that it is reasonably certain that the mold will not return from that remediated cause

Analytical methods.

The assessment consultant shall perform a visual, procedural, and analytical evaluation in each remediated area in order to determine whether the mold contamination identified for the project has been remediated as outlined in the remediation protocol.

Where visual inspection reveals deficiencies sufficient to fail clearance, analytical methods need not be used.

Passed clearance report.

An assessment consultant who determines that remediation has been successful shall issue a written passed clearance report to the client at the conclusion of each mold remediation project. The report must include the following:

  1. a description of relevant work site observations;
  2. the type and location of all measurements made and samples collected at the work site;
  3. the results of analytical evaluation of the samples collected at the work site;
  4. a clear statement that the project has passed clearance.

At Dry Effect, our Post Remediation Mold Assessment and Clearance Sampling consist of the following:

  1. Firstly, visual inspection of the previously identified contaminated area(s) and constructed containment(s);
  2. Visual inspection to verify that all impacted materials have been removed according to the Mold Remediation Protocol;
  3. In addition, visual inspection and complete documentation including digital photos of the remediated area(s) to ensure that all visible mold growth has been removed, that there are no wet building materials, and that the area(s) are clean and debris free;
  4. Collection of microbial air samples from each work area or containment and one or more surface samples of previously identified contaminated areas. Plus, the collection of one or more indoor control air samples from one or more areas inside the structure but outside of all work areas for cross-contamination verification; In light of no currently established Threshold Limit Values for the majority of substances of biological origins (including mold) that are associated with building-related exposures, the Remediator will only adhere to the guidelines of the American Conference of Governmental Industrial Hygienists (ACGIH) to determine if remediation efforts were successful. For purposes of the remediation described herein, acceptable or passing PRV / Clearance results will be defined as the indoor environment having a normal fungal ecology as compared to the outdoor fungal ecology. More specifically, a normal fungal ecology will be described as airborne mold spore counts that are quantitatively equal to or less than the outdoor mold spore counts, and qualitatively (species) similar. PRV Testing must be conducted within 48 hours of the completion of remediation efforts, and before containment is removed (if applicable).
  5. A final written report of the Post Remediation Assessment and Clearance Sampling findings and a Lab Report of the sample analysis; and,
  6. Issuance of a Clearance Mold Certificate upon passing Clearance Criteria.


At Dry Effect, we are committed to providing our customers with the safest and cleanest environment. Accordingly, we provide a 5 years mold-free guarantee.

So, why do we offer 5 years of mold removal guarantee for free? Because we are confident that our mold removal specialists will complete all the necessary steps during the first time itself.

If not, we will incur all the expenses to remediate any future microbial growth. (if it reoccurs in the same area within normal operations and under normal moisture and humidity conditions)*

*Dry Effect will make written recommendations after delivering mold remediation services. These recommendations are designed to minimize or prevent mold from returning. However, if the written recommendations are not followed and mold returns as a direct result of a disregard of our recommendations, the 5-year warranty may be voided at the discretion of the Dry Effect.
