PLEASE NOTE** ENVIROSERVE OF NJ, LLC does not use bleach in ANY form. Bleach only kills 80 to 90 % of the mold and removes none. This leaves an abundant food source for the 10 to 20 % left.

**Another little known fact is that dead mold can be more of an allergen than live mold in some cases. It is important to remove the mold not just treat it.

**The Remediator’s inspection can only detect mold growing on each individual wall or ceiling cavity actually inspected by the inspector. In other words, the Remediator cannot report on areas or locations in the building that have not been specifically inspected.

**Relative Humidity (RH) must be maintained at 50% or less to retard future mold growth.

**ENVIROSERVE OF NJ, LLC agrees to complete all work requested above according to EPA guidelines. All work is guaranteed to be completed as specified provided no changes are made. All work will be completed in a professional and timely manner.All agreements are contingent upon delays beyond our control. ENVIROSERVE OF NJ, LLC is not responsible for pre-existing conditions or damage visible or found.

**All materials removed will be properly disposed of off site per EPA guide lines.

**One year warranty on all work performed and accepted as of this contract.**

**Work site will be cleaned appropriately**

The Advantages of Cal-Brite Versus Cleaners, Biocides, Sanitizers, and Encapsulants

In order to perform mold remediation, one must first understand the categories of mold remediation products and how each works.

There are 4 basic categories that base most of the mold remediation products available today. These are as follows:

Cleaners Biocides Sanitizers Encapsulants.

A cleaner by definition loosens the surface material and thus makes it easier to wipe off or “clean”. Cleaners do not kill the bacteria or mold.

A biocide refers to an agent that kills bacteria and mold-biological agents. The last 4 letters of the word mean “kill/death”. Therefore, it means the death of a biological organism. There are several types of biocides. Fungicides are developed to kill mold. Virucides are created to kill viruses. True biocides are created to kill bacteria. However, different types of biocides are not effective against all molds or kinds of contamination. A virucide may have no effect against mold. Some biocides claim to be very effective but they are not necessarily as effective as a dedicated virucide or fungicide. no biocide is 100% effective against all types of mold and bacteria; a few spores may survive.

A sanitizer can kill bacteria or mold but renders inactive the mold or bacteria and makes it much harder for mold or bacteria to regrow on the treated sanitized surface.

An encapsulant covers the surface thereby not allowing any particles or items to escape from underneath the sealed surface. This does not kill the bacteria or mold. They are typically painted on and when they dry, the surface is sealed and hard to the touch. Therefore, nothing can penetrate up through the sealed surface. These can be used later in the remediation process with additives to deter regrowth. For example, zinc based encapsulants often deter the regrowth of mold. However, one must remember that the core cause of the moisture problem must be fixed (eg. structural repairs) or it will recur. Encapsulants should never be used in place of a mold remediation. An encapsulant such as drylock should never be placed over mold/fungus.

Remember, not all encapsulants work on all surfaces. The contractor should always perform a spot test before fully applying the encapsulant. Bubbles, cracks. and peeling indicate that the encapsulant has failed. If this occurs, another encapsulant should be

used or another remediation conducted. Even encapsulants that contain biocidal agents are not effective on actively growing mold.

Neither are encapsulants (e.g. Drylock) permanent solutions. Over time encapsulants fail and then more permanent steps would have to be undertaken. This may involve structural repairs. Therefore, encapsulant coated surfaces requires regular inspection and maintenance. Some encapsulants create hazardous wastes which require proper disposal.

Cal-Brite is a sanitizer and when used will kill as much mold as a more chemically potent or harmful biocide. In addition, it retards the regrowth of mold.

Chlorine bleach is a biocide. However, it is hazardous to people and should never be mixed with other compounds such as ammonia. Bleach leaves the surface wet or damp and slightly slimy to the touch. Since bleach does NOT retard the growth of mold like Cal-Brite does, the mold can regrow again leading to a vicious cycle of bleaching and mold growing. Eventually, the homeowner may become frustrated and ask if there if anything that does not act as a fertilizer that actually retards the regrowth of mold. Biocides are not recommended because the mold parts can still cause allergic reactions after they are dead. This is especially applicable to sensitized individuals.

Cal-Brite will kill the mold or bacteria AND retard its regrowth. Using Cal-Brite and following all EPA mold remediation project guidelines and cleaning steps if performed correctly by the contractor ensures that the mold and bacteria are killed and that the dead mold parts are vacuumed and removed to prevent allergic reactions in sensitized individuals.
