How To Detect Mold Under Flooring

Signs That Water Has Been Present For Some Time Such As Stains Discoloration And Warping Boards

Does a musty smell under my floors mean there’s mold or mildew?

When your basement or crawl space floods, it can leave behind water that seeps into the cracks in your hardwood floors. This is a common problem for homeowners after flooding and can be very costly to repair.

A small amount of accumulated water can already be a cause of serious problems. Check your pipes and surfaces where water leaks occur to avoid further complications with your hardwood floors.

How To Make Random Test Cuts To Check For Mold In Building Cavities

Random wall test openings: We have little confidence in and are reluctant to simply make random test cuts in buildings. Since water can take peculiar paths through hidden openings, such as wall plate holes drilled for pipes or electrical wiring or between single pairs of studs or ceiling or floor joists, cutting a hole that does not reveal a problem is no assurance at all that no hidden mold problems exist.

How To Identify Hidden & Visible Molds That Are Cosmetic Or Harmless Or Other Low

Cosmetic-only Ceratocystis/Ophistoma bluestain mold is shown on the floor joists in the new construction framing in the photo just above.

This is a harmless, cosmetic-only mold that does not damage the lumber and is not a pathogen for humans. Here’s a good example of the observation that not all “black mold” is “toxic black mold”. It will be totally hidden when the ceiling drywall is installed.

The mold shown in the photograph above is plain to see during construction, but will be covered and hidden completely when the contractor installs the ceiling drywall.

One of our clients discovered this mold during a renovation and was quite concerned that a major toxic black mold reservoir had been found in the building. The client was facing a very costly mold cleanup project if this mold had to be addressed as a toxic material. Luckily this was not the case in this instance, as was easily demonstrated both by a simple inexpensive lab test and confirmed by onsite inspection of other framing details discussed at “Cosmetic Molds” linked-below.

So sometimes the mold in your house might be only a cosmetic concern. “Bluestain” or Ceratocystis/Ophistoma is common on framing lumber and we often find it in attics on the under side of roof sheathing. Unless it’s in finished portions of living space where it creates a cosmetic problem, no particular action needed to address this black mold.

When To Make Strip Cuts To Look For Hidden Mold In Building Ceilings Or Walls

When there is an ongoing building complaint that makes us suspect hidden leaks or mold, if we strongly suspect a hidden mold problem but have not found its precise location, on occasion it is justified to make a “strip cut” across multiple wall studs or ceiling joists, exposing multiple wall cavities.

What makes a lot of sense sense is to study the building carefully to decide on the building points at most riskof having been wet from leaks due to construction details or other site observations. That’s where one wouldmake a test cut.

    Mold and mildew are often spoken of together, almost as if they were the same substance. We fear mold and mildew growing below our homes in crawl spaces, under house siding, around the bathroom wall surround, and behind the sink. Excessive, pervasive mold and mildew can hamper a house sale or cause homeowners to move their bedroom elsewhere. Neither mold nor mildew is welcomed in the home, in any form.

    Though the terminology can be confusing, mildew refers to specific types of fungus, including some types of mold. That said, not all mildew and mold should be treated the same. Safely eradicating mold and mildew is crucial to keeping you safe and your home in good shape.

    Mold Growth Is A Result Of Water Damage Moisture & Condensation

    4 Signs Your Home Has Toxic Black Mold &  How to Get Rid of ...

    Whether in the ceiling or under the floorboards, mold growth is a result of several factors – a slow water leak, a broken water pipe, or high levels of indoor condensation. Quite often, a very slow leak from a sink or toilet can go unnoticed for quite a long time. Eventually, mold will develop and the infestation will spread, particularly under the vinyl flooring or hardwood flooring. This is where removing mold under floorboards would be essential in providing a thorough cleanup.

    An indoor flood, when not properly remediated, can cause mold to grow quite quickly. In the event of a flood, professional remediation is highly recommended not only for the purpose of cleanup, but also to ensure that no mold will develop down the line. Anything short of a proper, comprehensive cleanup has the potential for mold to re-grow and re-infest. Without properly removing mold under floorboards there will certainly be resurgence of mold, and with damage.
