Mould Treatments

There are a number of techniques that concern mould growth, but unfortunately this inundation of solutions can lead to confusion and, in some cases, answers that are expensive at best and questionable at worst.

In Ontario, mould growth in attics is most commonly caused by a lack of sufficient insulation. As we all know, heat rises, and so too does the warm air in your house. As a result, the warm, moist air in your home tends to rise to the upper level, some of which escapes into the attic. In a properly insulated attic, the amount of air that escapes is tolerable, but with poor insulation it can lead to a buildup of warm, moisture-rich air that does not rapidly circulate, a breeding ground for mould development.

It need not be poor workmanship that allowed the development of those conditions either, over the last 40 years, building code and recommendations have changed as collective knowledge has been accumulated. A typical single storey home in 1970 was built to accommodate the recommended code of the time. The Government of Canada now recommends increasing the attic insulation to a minimum of twice the thickness for the exact same home, listing a plethora of advantages, one of which being the diminishing of moisture within the attic.

One might think that hot, humid Ontario summer months contribute to mould growth, but it is, in fact, the winter months that contribute most. It has been shown that mould can grow up to ten times faster in the winter months than the summer.

Being in the insulation business, we've seen the effects first-hand that inadequate insulation can cause. Unfortunately, we also saw a number of lackluster and expensive solutions proposed to home owners following a mould discovery.

There are a number of options available, firstly being to sand or brush the mould from the wood using sanders or wire brushes. While this technique does work, it is very labour intensive and is not time efficient in any regard. This translates into a large bill due to the technician needing to spend excessive amounts of time manually removing the mould.

It is possible to blast the mould from the sheathing using a physical media like dry ice, in a manner similar to sandblasting. This is considerably faster than manually sanding the mould from the wood, but the equipment required is very industrial and the blasting material is not readily accessible. Once again, we can see this will translate to a larger bill, due to the equipment and blasting media costs.

Here at Arctic Attics, we were unsatisfied with these, and other, options. We were determined that mould removal need not be expensive, nor should anyone need to stand in a stuffy attic manually scraping mould from the wood.

We use a concentrated spray that quickly and effectively stops mould growth and restores the wood to its original appearance before the mould growth, stripping it of unsightly staining and killing mould spores simultaneously. Not only is this extraordinarily time-effective, it also allows the mould remediation expert to do a better job, reducing your costs substantially and decreasing the time necessary to have a contractor in your home, allowing you to get back to normal more quickly.
