Mould Solutions

For Your Home. For Your Health.

Purify Enviro Group offers a wide variety of mould services and products for homes and businesses, including our proprietary Mold Be Gone formulation, free on-site inspections, remediation services, whole-home air and surface treatments, and even DIY solutions.

Industry-standard, bleach wipe downs and demo projects don’t deal with the airborne mould spores that have found their way throughout the property. Those traditional, yet ineffective, remedies only address the cosmetic part of the problem. Removing the visible contaminated materials does not necessarily improve the air quality and overall living environment. There is nothing that bleach, toxic chemical remediation and/or demolition can do about the potentially harmful mould spores that could cause adverse health problems for any occupants.

How to treat the mould?

People often ask what kills mould. They want to know what to use safely and effectively. Unfortunately, we have found that many people have incorrect information on killing moulds and often spend time, energy, and money trying to kill mould with inadequate products and techniques.

Not only does it waste time, energy, and money, but the mould grows and spreads in greater amounts than they started with.

Mold Be Gone is a completely SAFE mould remediation product which is a hypochlorous acid-based mixture of targeted essential oils. Purify Enviro Group disperses it, as a liquid, using a Graco Sani Sprayer, (as well as an aerosol fogger) that permeates soft surfaces such as carpets, drapes, furniture, clothing and can travel into every crack and crevice of your home.

Do you notice a musty odour in your house, apartment, condo, basement, or crawlspace?

Moulds grow best in warm, damp, humid conditions.

Quick Facts About Mould

That musty smell usually comes from basements, attics, crawlspaces, or other areas that lack proper ventilation and humidity control. Homeowners often find mould growing on paper products, books, cardboard boxes, and ceiling tiles. Mould will also thrive on wood, drywall, carpet, fabric, upholstery, and even dust.
Mycotoxins give off that musty odour.

Moulds spread and reproduce by making spores. It is during that growth and reproduction stage that mould produces gasses called microbial volatile organic compounds (MVOC). While many of these gasses are odourless, some, called mycotoxins, give off that musty odour, which is a sign that remedial action is needed.

Mycotoxins can cause a wide range of medical problems such as difficulty breathing, migraines, sinus infections, sore throats, bronchitis, pneumonia, depression, joint pain and inflammation, digestive problems, even depression and exhaustion.
CDC recommends professional mould removal and improved ventilation.

Recognizing that moulds in the home can cause health issues, the CDC (Centers for Disease Control and Prevention) provides useful information about how to handle it.
Depending on the extent of the mould problem, they recommend hiring a mould removal professional. The CDC says “a professional contractor will be able to safely remove the mould, ensure that all the mould is removed, identify the source of your moisture problem, and recommend the best course of action to reclaim your basement space.”

The CDC also notes the importance of improved ventilation in areas like the basement explaining that “basement ventilation increases air circulation in your home and allows air to escape outdoors while bringing fresh air inside the home. The best basement ventilation systems generally use a combination of an exhaust fan and air dehumidifier/purifier. The condition of your basement and your needs will help determine which system is right for you, and discussing the situation with a basement contractor will typically land you on the answer. To completely eliminate musty and moldy odors, though, some kind of basement ventilation is mandatory.”

How do I know if I have a wet basement?

The American Society of Home Inspectors estimates that 60 percent of U.S. homes have wet basements. That means that more than half of the North American homes could have indoor air quality issues brought on by too much moisture – this especially problematic with our climate in Canada. Whether it’s from subsurface seepage, rain-related or excess humidity, problems that start in the basement eventually have an impact on the upstairs. While it might not be your most used space, taking care of excess moisture issues on your lowest level, can go a long way to creating a more comfortable and healthier environment throughout the house.

Signs of a “wet” basement:

  • Do you have water stains or dampness on the walls and/or floor?
  • Is there ever condensation on the windows?
  • Can you notice a musty smell?
  • Is there any peeling or bubbling paint on the walls? Rot in the corner boards?
  • Have you seen rusty baseboard nails?
  • Is there rust around any steel support columns?
  • Does the floor have curling or loose floor tiles?
  • Can you see efflorescence – a white powdery substance on concrete walls or floor?
  • Have you ever had issues with a rusting water heater, dryer, washer, or other appliances?

 It’s important that homeowners understand that excess moisture, condensation, and high humidity levels in their basement can lead to a number of problems including structural damage, mould & mildew, as well as a whole host of health issues.

How can I reduce the moisture in my basement?

  1. Check for leaks in the foundation walls. Fill any cracks. Regrade soil around foundation walls to prevent water from moving toward the foundation. Direct downspouts far away from basement walls with downspout extensions and clean gutters.
  2. Insulate exterior walls to prevent condensation. In colder climates, insulating basement walls will save energy and reduce heating costs. (Don’t cover the walls with insulation if water is leaking in from outside as it will create a potential mould problem).
  3. Insulate pipes – condensation dripping from cold pipes can contribute to basement water problems.
  4. Seal leaky dryer vents with foil tape (not duct tape) to prevent unwanted humid air from entering the basement.
  5. If there is a basement bathroom, ensure it has a vent. Exhaust fan should be on during and after every shower.
  6. Keep basement windows closed during humid weather.

How can Purify Enviro Group help improve the overall health of my basement?

Once you are rid of the preventable sources of moisture, you have taken a big step towards improving the overall air quality of your home and protecting your investment.

The next step would be to treat the entire house and basement with our proprietary product Mold Be Gone.

Following the Mold Be Gone treatment, adding a moisture control and ventilation system that will maintain the optimum humidity level in the basement year-round is recommended, and is required to prevent the conditions for mould growth going forward.

Dehumidifiers can be helpful; however, they use a lot of electricity to operate, do not exchange the stale air or ventilate the basement and, in most cases, they need to be monitored and emptied on a regular basis.


A Humidex basement unit, properly installed by Purify Enviro Group, will improve indoor air quality. The Humidex unit exhausts stale air, and maintains humidity control ventilation for the entire home, eliminating musty odors and other airborne pollutants. Eliminating fumes and off-gases from paints, furnishings, carpeting, and household cleaning products prevents costly mold and mildew damage to stored items, furniture, and clothing. The additional benefits of this unit are that it recirculates warm air from upstairs to the basement, thereby improving heating and air conditioning efficiency.

Economical to operate 24/7, 365 days a year, a Humidex moisture control and ventilation system uses a fraction of the electricity that a dehumidifier uses. The energy-efficient Humidex units cost less than $5 a month in electricity compared to most dehumidifiers that cost as much as 10x that amount per month.

While it may not be your main living area, solving wet basement issues not only helps you enjoy your home now, taking care of this key area will help maintain or increase the value of your home in the long run.

For those customers that are interested in spreading out the cost of improved air quality over time, Purify Enviro Group is proud to offer financing of the Humidex units through the Manitoba Hydro Energy Finance Plan.

How can i improve the air quality in my crawlspace?

Crawlspace Ventilation – Common Problems

Poor indoor air quality in crawlspace

Crawlspaces tend to have high humidity, bad smells, and poor air quality;

Moisture damage in crawlspace

Moisture nourishes mould, odours, and pesky insects;

Structural damage from moisture

Moisture causes structural damage, such as wood rot in beams and floors, that can be devastating to a home’s foundation;

Radon gas dangers

Radon gas and toxic vapors enter the crawlspace from the ground, which are harmful to family’s health;

The Stack Effect

Natural air flow pulls the problematic air upstairs into the living areas;

Crawlspace Ventilation – Common Solutions

Foundation vents are designed to let air into the crawlspace: moist outside air comes right back in and aggravates the problems, failing to help lower humidity;

Dehumidifiers are the most popular approach for attempting to remove excess moisture… but they are costly to run and require a way to get rid of the condensed water produced. And they do not expel toxic vapors or improve air quality!

Vapor Barrier

Encapsulation: a vapor barrier is installed on the floor and continued up to the foundation wall to keep out moisture …, but it only helps with moisture infiltration, not with trapped indoor moisture and moisture saturated within the walls! It also does not create the necessary air exchanges that expel odors and improve IAQ (indoor air quality)!

Purify Enviro Group ‘s Solution

The ventilation system first measures the relative humidity and calculates the Dew Point of the space to determine how much air to exhaust. It then expels moisture, odors, stagnant air, and indoor pollutants as well as Radon Gas and toxic vapors entering the crawlspace from the ground.

Simultaneously an equal amount of warmer, drier, and fresher air is brought down from upstairs to replenish the air and maintain balanced air pressure.

The ventilation system creates permanent air circulation to prevent the formation of condensation phenomena, reducing mould activity as well as avoiding stack effect.

It reverses natural air flow so that damp polluted air doesn’t go upstairs and creates air exchanges that improve indoor air quality for the whole house.

Top 3 Purify Enviro Group customer complaints about their indoor air and how to fix them

How do I know if my indoor air is mouldy, musty, or unhealthy?

Unlike dirt and dust you can see, then vacuum or wipe away, it is harder to gauge how “clean” your indoor air is.

1. What’s that bad smell?

One of the most common complaints is that musty odour. It can start in the basement, infiltrating furniture or clothes stored down there, and end up giving the whole home an unpleasant smell. Sniffing out the source can be as simple as following your nose which often leads to the basement or crawlspace.

It’s important to understand that mould loves to grow in warm, damp, and humid conditions, spreading and reproducing by making spores. During growth and reproduction, mold produces gasses called microbial volatile organic compounds (MVOC). Many of these gasses are odourless, but some have a musty odour and are poisonous mycotoxins that can cause a wide range of medical problems.

Many homeowners try to cover up the mouldy smell with air fresheners, scented candles, disinfectant sprays, and household cleaning products. These strategies often just “mask” the odours, and are not a solution to the problem. This “masking” only prolongs your exposure to harmful indoor air that can compromise your health and the health of all the occupants in the home.

The only way to get rid of the mould smell is to remove the mould, then take preventative measures to ensure it doesn’t return.


2. Why is there condensation on the windows?

Customers complain about excess water condensation on the inside of their windows and glass doors. This can be a sign that there are damaging levels of moisture in the home or apartment, which can lead to poor indoor air quality. It can become especially evident when the heating is turned on as the outdoor weather gets cooler. Warm air hitting the cold windows can lead to ruined or rotting window frame finishes, and mold growth on windowsills.

In addition, well insulated homes that are sealed against air leakage can lead to reduced natural ventilation to the outdoors. According to the CHMC, after sources of moisture are taken care of, mechanical ventilation can be used to further control moisture conditions and improve indoor air quality.


3. Why am I coughing, sniffling or wheezing?

The United States Environmental Protection Agency (EPA) warns that being exposed to mould can trigger allergic reactions and asthma symptoms, as well as cause irritation of the eyes, skin, nose, throat, and lungs when exposed to airborne mold particles.

Health Risks of Indoor Air Pollution

It is well worth contacting Purify Enviro Group. We will come to your property and offer a free assessment of the situation, provide any recommendations and product solutions so that mould remains Gone for good.

What does the Canadian Lung Association say about mould and indoor air quality?

The Canadian Lung Association ( recommends that everyone should make healthy indoor air a goal. Canadians spend 90 percent of their time indoors and when the indoor air quality is poor, it can have an impact on everyone’s health and greatly affect people suffering from asthma, allergies, or lung disease.

Experts on lung health, the Canadian Lung Association notes that the basement is

“an ideal location where mould can grow since it is usually the dampest area of the home and often has poor air circulation. Exposure to mould can trigger asthma symptoms such as wheezing, coughing, and shortness of breath, as well as allergic reactions.”

On their website the Canadian Lung Association gives the following tips:

  • Maintain an ideal humidity level in your basement (between 30-50%). To measure humidity levels, purchase a hygrometer from a hardware or electronics store.
  • Use a dehumidifier in your basement if humidity levels are high. Remember to clean the bucket, coil, and fan blades regularly so it runs efficiently and does not put bacteria or mould spores back into the air.
  • Limit exposure to mold by having kids play upstairs or removing the basement family room.


The Purify Enviro Group Solution

While the Canadian Lung Association talks about the benefits of a dehumidifier, for nearly 30 years ClairiTech has been providing a better solution to improving overall basement air quality.

Dehumidifiers do not exchange the stale air or ventilate the basement. In most cases, they need to be monitored and emptied on a regular basis, and they use a lot of electricity to operate.

ClairiTech Innovations began with a mission to develop a healthier, drier, and more comfortable basement and home, at a fraction of the annual energy cost of a dehumidifier

Today, their patented basement moisture control and ventilation systems, properly installed, will improve indoor air quality by exhausting stale air and maintain humidity control ventilation for the entire home, eliminating musty odours and other airborne pollutants, such as fumes from paints, furnishings, carpeting, and household cleaning products, and prevent costly mold and mildew damage to stored items, furniture, and clothing.

Economical to operate, they will recirculate tempered air from upstairs to the basement, improving heating and air conditioning efficiency.

The proof is not only in the performance and the lower energy bills, it’s in the improved sense of well-being you will notice 24/7, 365 days a year.

Purify Enviro Group is proud to offer ClairiTech’s complete product line, which qualifies for financing under the Manitoba Hydro Energy Finance Loan.

Is mechanical ventilation the best option for your home?

Smart tips from Natural Resources Canada:

Whether your someone who enjoys all the efficiencies of a newly built home, or the character and charm of an older home, it’s important to understand all the ins and outs of how your place is ventilated. With improvements in building codes and construction practices, new houses tend to be more airtight while older ones require renovations and upgrading to eliminate leakage and drafts.

New or old, according to Natural Resources Canada (, fresh air needs to be moved around the house, particularly to rooms with closed doors, such as bedrooms. Without proper circulation, fresh air might not reach all the rooms in a house, which can cause pockets of stale or moist air. Getting that proper distribution of air throughout a house usually requires fans and ducting systems.

Signs of poor ventilation:

Natural Resources Canada explains that if

“a house is stuffy, has lingering odours, or has high humidity levels in fall and winter, it is likely the house does not receive adequate ventilation”.

They note that if any of the occupants have respiratory conditions, such as asthma, bronchitis, or chronic colds, getting the proper amount of fresh air is even more important.

Naturally, many people think that opening windows is the easiest way to provide fresh air, but they risk problems such as driving wind or rain, increased heating or cooling costs, and even security issues. Natural Resources Canada suggests that using a mechanical ventilation system, such as an exhaust fan or a heat or energy recovery ventilator (HRV/ERV), can be more effective.

Putting the control in the homeowner’s hands

While providing a number of possible solutions, Natural Resources Canada points out that adding mechanical ventilation, in addition to the required air exchanger, puts the control of household indoor air quality in the homeowner’s hands rather than having the weather dictate the air change rate within different parts of the house. This also allows for the house to be built or renovated to high air tightness levels that reduce heating bills and improve overall comfort, while ensuring good indoor air quality throughout. Recognizing how indoor air quality can vary depending on the season, having a system that both monitors and adjusts to changing conditions takes the worry out of the whole process.

Why Purify Enviro Group partnered with ClairiTech?

For nearly 30 years, ClairiTech has been single-mindedly dedicated to continuous innovation in mechanical ventilation. They built their reputation on moisture control and ventilation systems designed to create cleaner, drier air year-round by a three-step process. Our systems expel odors, excess moisture, mold spores and other pollutants from the downstairs where they are most concentrated. Air is replenished in the basement with a fresher healthier supply of air from upstairs, lowering the relative humidity. Ultimately, the entire home is ventilated with continuous air flow, extracting moisture that can cause structural damage, reducing biological growth of mold and mildew, and achieving healthier air. Once installed, the automatic sensor controls provide continuous ventilation to maximize performance, energy efficiency, and ease of operation 24/7.

With so many options available to homeowners these days, knowledge is power. Purify Enviro Group is dedicated to helping our customers understand all of the ins and outs of proper ventilation for their home, condo, apartment, or business; helping them enjoy their indoor space and breathe easier in the long run.
