High Humidity And Mold-Part 1

high humidity and moldHigh humidity promotes mold growth and can destroy a home or building just as the results of plumbing leaks or water infiltration from the outside.  Mold spores floating in air can take the humidity from the air and start growing on materials and surfaces, including walls and ceiling.

What is relative humidity?

The relative humidity (RH) plays a big part in promoting or inhibiting

High Humidity And Mold-Part 2

high humidity and moldHigh humidity can produce tremendous damage in a home or building.  In part 1 of “High Humidity And Mold” we explained the principle of the relative humidity and the relationship between humidity and temperature.  In this segment we describe various situations that could lead to high humidity and mold.  We reiterate that the relative humidity (RH) should be kept below 60% at all times.

With plumbing leak problems, the water damage and mold develop at a particular location – the  sheetrock is progressively saturated with water and mold sets in on the sheetrock, wood studs, and anything in that location.  With high indoor humidity the mold spores settle and grow on all surfaces.  It starts on surfaces with a haze and progressively the surface mold gets worse and permeates the surfaces and materials.

Mold Removal Is A 3-Step Process

mold removal is a 3-step processMold removal is a three-step process. First, it includes  the mold assessment phase to document the problem through an inspection as well as mold testing to assess the degree of mold contamination; second. the mold remediation phase to fix the problem; and, finally the post-remediation phase which insures that the mold remediation has been performed properly and the air quality is within the normal range.

What Is A Mold Inspection?

what is a mold inspectionA mold inspection is a visual and non-intrusive inspection of a building performed by a licensed mold inspector, also known as a mold assessor.   The purpose of a mold inspection is to identify and to document any red flags that are present or conditions that could lead to mold growth.  If a mold contamination is found, the mold inspector will formulate a hypothesis about its origin, so that he can outline solutions in his mold inspection report.

Can Mold Testing Prove A Building Is Mold-Free?

can mold testing prove a building is mold freeThe answer is no! Mold testing does not prove or guarantee that a building is mold-free. Some home-buyers mistakably equate mold testing as insuring a mold-free building.

No-one can guarantee 100% that a home is mold-free, and this is why:

If we tested every room of a typical 3 bedroom home, we would have, as a minimum, 3 bedrooms, 2 baths, a kitchen, a living room, a dining room, and a laundry room.  That’s 9 rooms plus the outdoor sample making a total of 10 air samples.

When Is Mold Testing Warranted?

when is mold testing warrantedThe question as to when mold testing is warranted is dictated by the goal or objective of the homeowners or building occupants.  Many people who call for a mold inspection actually only need mold testing.  Once we start asking questions about their objective, 95% of the time we will recommend mold testing over a formal inspection of the entire building.

We recognize that every situation is different and there are times

Who Pays For A Second Post-Remediation Mold Testing?

who pays for a second post remediation mold testingWho pays for a second  post-remediation mold testing is a contingency that should be spelled out in the contract—not when this unhappy situation arise.

A second mold testing following remediation means that the mold remediation failed air clearance.  It is customary for homeowners to pay for the first mold testing following mold remediation; and, if the remediation is covered under the homeowner’s insurance policy, the cost of the post remediation testing is normally part of the remediation process and covered by insurance.

But, when the mold inspector delivers the bad news that the remediation failed air clearance, and he recommends in his report that additional mold remediation is necessary, the question becomes …
