This mold remediator directory lists Mold & Asbestos Cleanup Services: this article provides names and addresses of professional mold remediation companies. InspectApedia is an independent publisher of building, environmental, and forensic inspection, diagnosis, and repair information provided free to the public - we have no business nor financial connection with any manufacturer or service provider discussed at our website.
Green links show where you are. © Copyright 2013 InspectAPedia.com, All Rights Reserved.
This article describes and gives contact information for some of the many outfits who advertise as performing mold, lead, or and asbestos remediation. Other mold remediation companies not listed here may be just fine as well. To avoid any conflict of interest, InspectAPedia.com has no business nor financial relationship with any service provider or product discussed at this website. No fees are charged for directory listings at this website..
Where the asbestos or mold cleanup need is technically challenging due to occupant illness, scope of work, difficulty of containment, or as indicated by an inspection and remediation plan prepared by an expert, the owner/occupant arranging for cleanup should obtain more than a single estimate for the work described in the remediation plan.
The more you can read mold inspection, testing, and cleaning articles that we provide at the MOLD INFORMATION CENTER the better you'll be equipped to judge the competence and honesty of people you are considering hiring.
Avoid Conflicts of Interest Between Asbestos or Mold Testing & Mold Cleanup
Watch out: Avoid a potential conflict of interest. The company or professional you use to inspect and test for mold contamination and to prepare the mold remediation plan should have no business or financial relationship with the mold cleanup or mold remediation company. The post mold remediation clearance inspection and testing can be performed by the original expert who inspected and tested for mold contamination. Independent mold experts who inspect and test for mold are listed at MOLD TESTING SERVICES.
Watch out: hire an expert. Make certain that any environmental testing and remediation plan preparation as well as actual mold, asbestos, or other building environmental cleanup jobs are performed by qualified experts. Details & examples of what can go wrong are at ASBESTOS REMOVAL, Amateur, Incomplete and ASBESTOS REMOVAL CERTIFICATIONS.

When To Perform a Post Mold Remediation Mold Clearance Inspection & Test
Where significant cleanup costs are involved or if there are other risks at the property (such as vulnerable occupants) it is appropriate to schedule a mold clearance inspection and testing after the cleanup is complete, before any new materials are brought into the building, before containment is taken down, and with 24 or more hours of time after the end of cleaning to allow local dust particles to settle (and be tested).
Regardless of which company is involved, the success of the cleanup depends on many factors including the particular site crew and the presence of and expertise of its supervisor.

General Advice on Working With Contractors and Consultants
Be careful how you ask contractors or consultants for advice because if they are nervous they may be inclined to give you advice which is mostly safe for them, not for you, by telling you either that you simply cannot do something, or that you need to do the most extensive and expensive (and profitable for them) steps, tests, repairs, products possible.
We call this the SOPM problem (Spend Other People's Money)- when an attorney, consultant, or other expert spends his/her client's money not so much to benefit the client, but rather, to reduce risk for the consultant that the client will later complain about the consultant's advice. The consultant gives advice that reduces their risk but doesn't cost them a dime, as it's the client paying for additional tests or services.
As a consumer you can reduce your SOPM cost by being straightforward and reasonable in both your conversation with and your expectations of your consultant.
How to Manage a Mold Cleanup Project Successfully
Here are some tips and warnings about mold cleanup jobs, based on our field and laboratory experience:
DO NOT start any expensive mold cleanup problem before we are confident that we fully understand where all of the problem reservoirs may be in the building as well as their causes. For example, often attic mold is not just a fault of bad venting but also high building moisture which could have produced a concern elsewhere.
DO NOT start tearing off your roof or tearing apart other building areas before you know the full extent of all of the mold problems and leaks on the building. For example, tearing off a roof over a moldy attic is unlikely to be necessary unless the roof is itself damaged and the sheathing or framing rotted.
DO NOT agree to any “spray to kill” treatment or “fogging” or “ozone” treatment as a substitute for actually cleaning off or removing moldy materials – sprays alone are ineffective, costly, and sometimes dangerous.
DO NOT rely on mold swabs, mold cultures, or simple air tests for mold alone, as these methods alone as means to screen a building for problem mold are very unreliable.
Where attic or basement mold is visible or where there has been substantial leakage into building wall cavities you should also be concerned that the mold you see may not be the most important mold – there could be other more serious mold reservoirs – another reason to hold off on any testing by someone who doesn’t understand this and who may not know where or how to look.

Advice About Mold Sprays: Fungicides and Encapsulants for Mold or Particle Control
For details about this topic please see: MOLD SPRAYS, SEALANTS, PAINTS
You will want to establish that the fungicidal mold spray material or mold encapsulant is harmless in all
regards, that is, not combustible, non toxic, and that it won't change
the building surfaces or any sprayed insulation (such as in HVAC ducts) in a way that harms the equipment (say by corrosivity
or by trapping water or moisture, or by interfering with the adhesion
Even when you have that mold encapsulant or fungicidal spray use data (most likely in form of general advice from the spray manufacturer), you'll still want to inspect the equipment from time to time, maybe after a few months and then annually, for any sign of a problem (like trapped water, corrosion, unanticipated movement of insulation, or encapsulant falling off).
Frequently Asked Questions (FAQs)
Question: reader complaints about mold remediation, water damage, & flood cleanup services - flood damage & cleanup results interfered with sale of home
I am working on behalf of my parents, both seniors. My father is on Medicaid and hospice, and my mother is 85. I am trying desperately to sell a property on the Jersey shore that was severely impacted by Hurricane Sandy. We had the house under contract for a good (cash) price, and then lost the sale since our buyers lost their buyer, and the housing market collapsed down there.
We took on 4 feet of water in the first floor which has the entryway, closets, garage and 2 utility rooms off the garage that have doors but no ventilation except windows. We had ServPro a large "disaster-specialist" do the demolition and drying out of the place, but aside from removing drywall and debris, running fans and dehumidifiers and applying Sporicidin, there was no encapsulation of the affected areas. That was in November 2012. I thought we were good. Little did I know I was about to get a crash course in mold remediation.
We rebuilt the property with drywall and Pergo flooring (not the best choice) and since it was primarily my father's residence (he went into a nursing home shortly before the storm) the place stood mostly empty without ventilation or dehumidification running on the ground floor with the garage, foyer and two rooms.
So we got another, much lower offer, which we accepted and the buyers did a home inspection. They found evidence of mold in one of the rooms off the garage. To me it looked like green dust on the drywall with no evidence of water stains, but the room smelled of mildew. I figured it was just due to the fact that the room was closed off with no ventilation and they tested in late July. The air sampling showed extremely high levels of Pen/Asp in the one garage room and Stachybotrs in an upstairs hallway, among other things.
So we contracted with a "certified mold remediator," Healthy Way of NJ, in late August. They removed 22 linear feet by 2' high of drywall in the room off the garage and in an adjacent unfinished closet where there was visible mold on the studs, and sealed the concrete block and all exposed lumber it with what the invoice says is "valprene vi 250 white" mold-resistant encapsulant. They took up a few floor boards and it appears they treated the material under those as well. They thought that since ServPro did not properly treat the affected areas the mold was never properly remediated and simply came back.
Also, because of a lack of communication on their part, they did not address the Stachy levels on the second floor at the same time, which was due to black mold around the furnace/air conditioning unit and hot water heater. So the first floor room sat for 2 weeks till I got techs in there to remove the heaters in the closet on the second floor so Healthy Way could remediate around and under them.
They used "Fiberlock IQ 6100," a clear encapsulant, on the wood floors surrounding the heaters after sanding the floors and setting up negative air containment and ran air scrubbers. Then they did a post air test which came back again positive for very high levels of pen/ asp in the garage room but the second floor hallway came back clean. The test that ran in the kitchen came back with no results (defective cartridge or media apparently). Apparently they did not re-treat the garage room that sat without dehumidification for 2 weeks from the end of August and into early September before testing. I was told the room should be fine sitting without a dehumidifier. We missed a closing date as a direct result of Healthy Way's mismanagement of the project. That is another story.
So I call to complain to the president of the company. He says it is not uncommon to have to go back in to an area that failed with air scrubbers to get a clean test. So the sales guy goes back in to that room, sets up negative air and runs air scrubbers. I do not believe he waited 24-hrs with the scrubbers off before re-testing, as the kitchen, which is pretty impossible to seal off since it's an open floor plan with two stairwells, had an air scrubber running with no containment.
So that was a week ago and I still don't have test results back and my calls are unanswered at this point. Also, a week ago I was informed that the buyers want to do their own "inspection" after we get a clean test back, but until I read your very informative site I did not understand what that could potentially mean. I thought it was a visual inspection. Containment areas have surely been taken down, and the test was a week ago. I put a large capacity dehumidifier in the second garage room (that had moldy blinds removed and wood treated with that same white encapsulant) when I was down there a week ago, but could not put one in the other garage room since containment was still set up (looked like it was sealed properly but I did not take pictures).
Sine this industry is not regulated (I believe there is a bill in the NJ congress to certify mold remediators, among other things) I feel like I am caught between the law as a seller of a property and an industry who's standards I knew little about until today. I am taking care of my elderly parents and a young child of my own and untangling my father's financial affairs which includes selling this condo has taken up an inordinate amount of my time and energy. Any help or advice you can provide would be greatly appreciated. You can email me or call my cell, - K.V. 9/13/2013
Reply: mold remediation needs to find and remove the problem reservoir; conflicts of interest may have affected your results.
Yours is a long message with lots of information; I am indeed sorry to read about the hassle you've been going through, and would like to help; but I didn't see a specific question.
In general a "mold- spra" or encapsulant is not a good substitute for finding and removing the problem mold reservoir, though after thorough cleaning the use of encapsulants and sealers is fine as "extra insurance".
Similarly, running an air scrubber will not correct indoor airborne particle contamination (mold or otherwise) if the problem reservoir has not been adequately removed, or if poor dust containment spread contaminated dust to the building's HVAC system or to other building areas. Imagine trying to vacuum up dust-bunnies in the living room by waving a vacuum cleaner wand in the air in the kitchen!
At CONFLICTS OF INTEREST we explain that the expert who defines the scope of work as well as the expert who performs post-cleanup or post mold remediation inspection and testing shoud be someone who is wholly independent of and has absolutely no financial relationship with the contractor who performs the cleanup. That independence protects everyone.
Bottom line, to protect yourselves and to make the buyer comfortable you want them to have their own, independent, COMPETENT inspection, that might also include testing; There might be some interpretation needed of those results, depending on what's found.
Keep your sale glued together by being very clear to buyers that you understand perfectly the reasonableness of their concerns and that you will work with them to make right any substantive issues that arise. Unsaid is that of course we have to agree that a question raised is legitimate and substantive. But it's making a buyer worry that a seller is doing a cover-up and leaving the buyer with a big expensive surprise that will scare off a buyer.
