    Cleaning Up Small And Medium Mould Problems

    Bleach is not necessary to clean up mould.

    You can clean up small areas of mould if you follow the proper procedures and use the right protective equipment. Unless the mould growth is on smooth surfaces such as bathroom tiles, surface cleaning will not eliminate the problem.

    In most cases you can clean up medium areas of mould if you follow the proper procedures and use the right protective equipment. Materials damaged by mould must be physically removed and disposed of under safe conditions. However, it is important to seek professional assistance if there is a large mould problem or if mould comes back after cleaning.

    Susceptible individuals such as pregnant women, infants, children, the elderly, and occupants with asthma, allergies or other health problems should not be in or near the area where the mould is being cleaned up.

    Minimum protective gear needed:

    • a disposable N95 mask and
    • household disposable gloves.

    You can purchase an N95 mask from a hardware store. Make sure that the label says “N95”. Other masks are designed to provide limited protection against dust and are not suitable for protecting against mould exposure. Make sure that the mask is properly fitted and you can breathe through the mask.

    In Buildings Insulation Mold And Other Hidden Mold Reservoirs In Buildings

    This document describes how to find mold and test for mold in buildings, including how and where to collect mold samples using adhesive tape – an easy, inexpensive, low-tech but very effective mold testing method.

    We discuss the problem of hidden mold reservoirs and steps to take to find such problems in buildings. The mold contamination show at left is described in more detail

    at HIDDEN MOLD in CEILINGS / WALLS.

    This procedure helps identify the presence of or locate the probable sources of mold reservoirs in buildings, and helps decide which of these need more invasive, exhaustive inspection and testing.

    In the photo at page top we see the results of a wall cut through drywall to expose wet moldy insulation, mold on the cavity side of drywall, and surprise! a leak in a pipe that the owner did not know was in her basement wall.

    However there was good evidence in the form of stains on the exposed side of this drywall. Look at the tan stain which is in the photo in the half-round shape directly above the wall cutout.

    Watch out: just a light touch is needed.

    Don’t try to investigate a building by dashing about with an axe cutting holes willy-nilly.

    You Feel Like You Have A Lingering Cold Or Are Battling Flu

    “It is pretty tough to detect until it starts coming through the walls because mold, as you know, is a problem with some sort of leak somewhere,” Hayes-Raitt said. “So the problem starts behind the walls. But if you’re getting sick, it might be because of a mold problem.”

    If you’re dealing with symptoms that you can’t exactly pinpoint, it could be that you’re stressed, haven’t been taking care of yourself, or wound up with some sort of virus, of course, but it could also potentially be that you’re dealing with mold.

    If possible, Hayes-Raitt said that one of the best ways to determine if the sickness you feel is related to the house or not is to leave for a few days and then return home. If you feel those same symptoms coming on again, it might be the result of something more than a cold or virus.

    What If The Home Seller Or Builder Did Not Disclose A Known Mold Problem

    If the prior owner of a house you bought knew of the presence of mold and was required to disclose this information under state real estate disclosure rules, but did not do so, the owner may be liable to you for failure to disclose. See the Nolo article, “Mold: Who to Sue” for more on the subject. Other useful Nolo articles include “Home Defects: Sue the Seller,” which provides useful advice on determining who’s legally responsible for home defects and how to file suit.

    Where To Look For Hidden Mold On And Under Carpeting And Flooring

    DIY mold detector

    Lift carpets to inspect carpet tack strips and carpet padding and carpet underside.

    Water stains on carpet tack strips and rusty carpet tacks on those strips are other indicators of the leak history in the area.

    Remember that mold may be present on the under-side of the carpet itself or on the top or under-side of carpet padding located below the actual carpeting. Hidden mold may be found on the floor surface below the carpeting, or even between layers of finish flooring and subflooring.

    We also find mold quite often on the under-side of subflooring. Look up at subfloors from basements or crawl spaces where a wooden subfloor is installed on furring or “sleepers” placed over a concrete slab, it may be necessary to cut small test openings to explore these hidden cavities.

    The best place for a test cut to look for mold over an inaccessible floor or any other building cavity would be where we suspect that water has been most likely to be present, but openings may also be made in unobtrusive spots nearby, such as in a closet or under shelving where the cosmetic damage will be minimized.

While it can be difficult to detect mold in the walls, its important to look for these signs of mold growth, to identify the problem as quickly as possible. Moisture meters and particle counters can be used by a certified inspector to source the water leak and fungal growth and even help detect if there is mold in your walls.
