    Re: Mold Prevention - MicroShield Environmental Services

    Posted by DD on 9/24/05

    Thanks for the information on the chemical they are using. It seemed strange that over the course of
    only a day or two we had a big spurt of builders recommending them yet not one of them said anything
    about the chemical being used. If you ask me they were schills because there's no way in hell a
    major home builder would recommend a mold prevention company without discussing the actual chemical
    being used. The only thing these so-called biggy builders discussed was the level of service they
    got from the company (how they showed up on time and gave them some nice paperwork), it's beyond
    silly to think we would fall for that kind of non-sense. When you are in the business of building
    hundreds of homes a month you don't just willy nilly hire someone to cover 1/2 million dollar plus
    homes with a pesticide without taking an interest in the type of chemical being used. You would
    definately make it the focus of your discussion when you hop online to talk with others in the
    business, and you would most certainly would take in interest in the material you just posted.

    These mold prevention yahoos are idiots if they think service with a warranty is all a builder is
    looking for. In addition, we've seen alot of these guys making product claims that can't be verified
    and numerous companies trying to disguise who the manufacturer of their product is. The latter, I
    presume, is due to the fact that they don't want others knowing where they get their product and/or
    they don't want us verifying the claims they are making on someone else's product.

    How many more times are we going to hear someone say their product is EPA registered only to find
    out there is no EPA registration on the product they are selling?

    How many more times are we going to hear someone say their product is patented and can't be bought
    anywhere else only to find out they don't have any patents on the product?

    How many more times are we going to hear someone say they are the manufacturer only to find out they
    are not the manufacturer?

    How many more pesticide product claims are we going to hear about that can't be verified?

    If you are in the business of mold prevention and want to promote your product and/or service
    here I would suggest providing the following information from the get-go before you get your
    company's butt ran through the wringer in this dicussion forum:

    Links to the Material Safety Data Sheets, Technical Data Sheets, Product Labels, EPA
    registrations and State Pesticide registrations that exist, if they do exist, on the product you are
    using or selling.
    (note: It's apparent that most of you do not understand what kind of claims
    you can make regarding your product under the rules followed by the EPA. I suggest you bone up on it
    at EPA.GOV before discussing what the benefits are of using your product because sure as shit if you
    make a claim that is not allowed on your product someone here is probably going to drop a dime on
    your ass with the EPA.)

    The length of time you have been in business.

    Level of product liability and general liability insurance you have.

    If applicable, any current federal and state licenses you have secured.

    Any warranties your firm offers with a link to those warranties in full and the name of the company
    backing the warranty.

    Also note: if there are any judgments, liens, licensing issues, or other matters of public record
    that can be found on your company or the principles involved in your company they will probably be
    uncovered during the course of the discussion here (this is a law forum in case you haven't
