      Can Spraying or Fogging Kill the Mold?

      Spray cannot kill mold. Spray is the same as encapsulation or painting and in time the mold will continue to grow. The mold must physically be removed and the source MUST be fixed in order for the mold not to return. Mold spores release toxins even if they are dormant. So realistically, waste of money  

      Can you treat mold in the attic by encapsulating, painting or covering it up?

      Encapsulation is not an effective way to remove mold in the attic. This will Cover the surface but not get to the root of the mold. Mold in an attic or on any organic material MUST be physically removed for it to be completely gone. If a company try’s to sell you on this “encapsulation” technique, walk away!

      Does An Air Quality Test Need To Be Performed In The Attic After The Mold Is Removed?

      Air quality testing does not need to be done when dealing with mold in the attic because it is not a living space. Visible inspection or tape lift sample can work. But it is still important to remove of the mold and fix the source because in time, the roof will become so destroyed that it will be left to collapse – then we have a bigger issue on our hands.

      How Can I Reduce Mold Growth?

      There are a few steps in which you can reduce the chance of mold growth. These are common actions that any home owner can take, however are not 100% guarantee solutions.

      1. Keep humidity levels as low as you can—no higher than 50%--all day long. An air conditioner or dehumidifier will help you keep the level low. Bear in mind that humidity levels change over the course of a day with changes in the moisture in the air and the air temperature, so you will need to check the humidity levels more than once a day.
      2. Use an air conditioner or a dehumidifier during humid months.
      3. Be sure the home has adequate ventilation, including exhaust fans
      4. Clean bathrooms with mold killing products.
      5. Do not carpet bathrooms and basements.
      6. Remove or replace previously soaked carpets and upholstery.
      How Do I Know Its Mold?

      In most cases mold growth is obvious and can be confirmed with a visible inspection. There are many different types of mold and it can come in a variety of different colours (black, brown, green, white, etc).

      If left untreated, mold will continue to grow and spread and may become a much more dangerous issue; therefore a certified mold remediation company should be contacted to determine the severity and the best way to remediate.

      Another way to identify whether it is mold or not, is to have the area tested for mold. An environmentalist can come in and take a swab or perform and air quality test to determine what type of mold and how elevated the mold spores are.

      How Is Air Testing Performed?

      In order for an air test to be performed, a minimum of two samples must be taken. The reason for this is because there must be one sample as the control test (typically taken outside) in order to establish a base point of mold spores that are general acceptable levels. Seeing as how mold is everywhere, depending on your location and conditions, these levels can change. An additional sample is taken in every area of the home/building in which you may believe could have an issue.

      Hiring a company that does not have the proper experience for mold testing is a risky move to make. Make sure to do your research and hire a reputable company that has the proper education.

      Purchasing a home mold test is also not a good solution. Seeing as how there is mold everywhere, the test will automatically come back positive. The important thing is knowing what type of mold is present as well as how elevated the spore counts are.

      How Long does it Take to Remove Mold from the Attic?

      Depending on the size of the attic, mold remediation can take anywhere from 1-3 days. For a regular size home between 1200-2000 sqft it typically takes one day. The areas of the attic access are contained and an air scrubber is placed along with negative air pressure. The mold is physically removed from the wood and the entire affected area is hepa vacuumed and wiped down with anti-microbial.

      How Long Does Mold Removal Take?

      The length of the mold remediation process varies depending on the situation and the size of the area affected.
      If the mold is restricted to a small localized area it can take 1 day to remove. If the mold is in several areas of the home or the area affected is quite large it can take 2-4 days to remediate.

      Anytime mold remediation is complete, containments along with negative air and air scrubbers are left in place for an additional 24-48 hours. This ensures that any existing mold spores are killed and a thorough air exchange is complete.

      Is Encapsulation or 'Painting' the Correct Solution?

       Encapsulation, or commonly known as “painting”, is not the correct solution for removal mold in an attic. Let’s think of it as a Band-Aid, which only touches the surface, whereas the root is still left. If the root is not completely removed from the wood, it can continue to spread and the situation get worse. Mold in attics needs to be physically removed, which can only be done by a media blasting or grinding. Home inspectors fail attics that are white since they know there is a problem.

      Is Mold Harmful?

      Reactions to mold, and its variations, show up in the form of certain symptoms, usually brought on by an allergic reaction or possible infection.

      Mold allergies, being the most common symptom, can mimic other common conditions such as a cold or typical hay fever.

      Some examples:

      • Itchy throat and/or skin
      • Sneezing and coughing
      • Congestion
      • Headaches

      are most likely what to expect, among other similar reactions.

      In more severe cases, with stronger symptoms, a form of toxic mold is usual a suspect.

      In the case of infections, usually it is the result of an airborne mold which is breathed in. The most susceptible to these types being the elderly, or those with weakened immune systems.

      Should The Insulation In The Attic Be Removed If There Is Mold In The Attic?

      If more than 25% of the attic is effected by mold, than yes, the insulation needs to be replaced in the attic. At this point, the mold spores are already in the insulation and they need to be disposed of as well when the media blasting takes place, the insulation acts as a filter and captures the mold spores. When the insulation is being replaced, make sure proper ventilation is being installed and the proper amount of insulation is being put in.

      What Are The Costs of Mold Removal?

      The cost of mold removal varies on several different factors. Each individual job has a specific scope of work that will determine the cost of the remediation. A job can start at $500 and go up from there, again, depending on the scope of work. Factors that affect the scope of work are;

      a) How long the removal process will take
      b) Amount of affected area that needs to be removed
      c) Amount / size of containments needed
      d) The number of equipment needed (ie. Negative air, air scrubbers)

      What Are The Different Types of Mold?

      There are over thousands of various types of molds. The amount of types of specifics of mold exists is unknown. It is in the upwards of tens of thousands various specifics of fungi which grow is various shapes and colours. Molds grow best in warm, damp, and humid conditions, and spread and reproduce by making spores.The most common types of mold found indoors are:

      • Cladosporium
      • Penicillium
      • Alternaria
      • Aspergillus
      What Are The Methods to Remove Mold?

      There are several different options for removing mold, all depending on where it is growing and what type of mold it is.
      Anytime mold is growing on organic material it must be physically removed.
      a) Drywall
      b) Wood Structures/ Studs
      c) Panelling

      According to the IICRC Guidlines (Institute of Inspection, Cleaning and Restoration);
      “Physically removing mold contamination is the primary means of remediation. Mold contamination should be physically removed from the structure, systems and contents to return them to Condition 1. Attempts to kill, encapsulate or inhibit mold instead of proper source removal generally are not adequate.”

      Institute of Inspection, Cleaning and Restoration Standards

      Physical means of removing mold consist of;
      a) Full removal of material (cutting out affected drywall)
      b) Soda Blasting
      c) Grinding

      Depending on what materials the mold is growing on will determine the best way of removing it. Mold on drywall and mold on plaster will be fully removed even including 2 feet around the affected area to ensure all mold growth is removed.
      Mold in Attics is removed by Soda blasting, which blasts the mold off the sheathing and studs to ensure all the mold right to the root is removed.

      Watch our video on how we remediate mold in attics:

      When mold is growing on non-organic material or is just a surface mold, using a mold control product or hot water and soap can be sufficient.
      a) Bathtubs
      b) Sinks
      c) Window Sills

      Another very common area for mold to grow is in the shower/bath tub grout or caulking. Because the bathroom is a damp space is it very important to have a fan that is in working order and anytime a shower is used, make sure the fan is left on for ½ hour to an hour. Sometimes this can be cleaned up by yourself but to be safe, contact Canada’s Restoration Services first!

      What Causes Mold?

      There are a few factors that create the conditions necessary for mold growth.
      Your most common being environments that have undesirable levels and/or excess of the following:

      • Warmth
      • Oxygen
      • Darkness
      • Humidity

      However, these issues being fairly common in any average home, the biggest culprit to the development of mold is moisture.

      Typical reasons for this being present range from leaks (roof, pipes) and condensation buildup due to poor ventilation. Areas particularly vulnerable are basements and generally damp spots left undisturbed for mold conditions to thrive.

      What Is Air Testing?

      An Air Test or “IAQ” (Indoor Air Quality) is performed by taken samples from the air and seeing which mold is present and their spore count levels. An air test is typically conducted when there is a “musty/earthy” smell and no visible mold to be seen. Or if there is a concern about other possible particles that could be in the home (ie. Dust, asbestos, etc) that may be harmful to you and your family. These samples are taken by a certified environmental company and sent to a laboratory to be examined. There are minimum of two samples taken, one being a control sample (typically taken outside) as well a sample from the affected area of the home. If you have several areas in the home that are a concern, then several samples may be taken.

      When having an IAQ test performed, make sure to do your research on the company before hiring. It should be a reputable company with proper education and experience.

      What Is An Acceptable Amount of Mold Spores Indoors?

      Since mold spores are everywhere, there is no standard level of mold spores that you should have. How it is determined if mold spores are elevated is based on the surrounding environment. Therefore, every home will have a different acceptable number of mold spores.

      An air quality test (or IAQ) is performed to determine if there are elevated mold spores within the home. A sample is taken from outside (as the controlled amount) as well as in the areas of the home you think may have elevated mold spores.

      Signs of elevated mold spores;

      a) Earthy / musty smell
      b) A frequent buildup of dust
      c) Re-occurring sickness (ie. Cold/respiratory issues)

      What is the Correct Way to Remove Mold in the Attic?

      Mold in an attic or on any organic material MUST be physically removed for it to be completely gone. The most effective way to remove mold from an attic is media blasting. This technique blasts the mold completely off the wood and gets right to the root. If a small area is affected, than the mold can be grinded off as well, which gets right to the root as well.

      What's The Difference Between Mold And Mould?

      The only difference between the two is really the spelling. Canadian\British (MOLD) and the American (MOULD). They can be used interchangeably without any concern of confusion when dealing with a certified professional company dealing in such.

      Where Can Mold Grow?

      Mold can naturally grow anywhere as long as the right environment and conditions are present. Molds are found in virtually every environment and can be detected, indoors and outdoors, year round. Mold requires an organic material, moisture and lack of air flow in order to grow and can be found both indoors and outdoors. Outdoors they can be found in shady, damp areas or places where leaves or other vegetation is decomposing. Indoors they can be found where humidity levels are high, such as basements, showers and attics.

      The most common location for mold grow are;

      • Attics
      • Baseboards
      • Shower Grout
      • Drywall in Bathrooms
      • Under Kitchen Sinks

      Who Can Give Warranty for Mold Removal?

      Anyone can give a warranty for mold removal but the important thing is to make sure it is done properly. If the process is not done properly, you can be guarantee they will not warrant the warranty and find any way to get out of it. If a company encapsulates the mold, and the source is not fixed, then of course the mold will grow back and it will not be their fault. Make sure the company is properly certified, technicians are certified and that the mold is being physically removed as well as the source is being fixed.

      Why Does Mold Grow in the Attic?

      Attic mold is a common problem and is caused by one thing, and one thing only – moisture! Some obvious culprits that may be responsible for the unwanted wetness include insufficient ventilation, too much or too little insulation, and roof leaks. Other sources are bathroom exhaust fans, kitchen exhaust fans, and clothes dryers which are all designed to pump moisture out of the house but should never be vented in to the attic. This source MUST be fixed when removing mold in attics or the mold will just come back in a matter of time.

      Why Hire Mold Removal Contractor?

      There are some important factors to consider when dealing with mold removal and remediation. A professional company will not only be outfitted with the proper safety equipment, but will know how to avoid potential cross contamination through airborne mold spores. This can lead to other rooms being affected or even your health.

      The steps involving identification, protection, removal and prevention of returning mold are key when considering a professional contractor.
