The warranty is listed on the property and is transferred to the new homeowner, if you decide to sell your home.

Look For Exclusions In The Warranty

This is a big giveaway. If the service a contractor is offering doesnt actually solve the problem, the verbiage in the warranty will reveal the lack of confidence. Youll find it lurking amidst the legal jargon as an exclusion against any recurrence of moisture issues. Which, of course, is the whole reason you would seek a warranty in the first place. Mold growth only occurs when elevated moisture is present. It will not grow in a dry attic. Therefore, if a warranty becomes void in the presence of elevated moisture, the treatment hasnt accomplished anything.

Not All Sheathing Is Equally Mold Resistant

Ironically, despite the many gains weve made in the building codes, weve still managed to install progressively worse and worse attic sheathing materials over the decades. Of course, the problem of mold growth is much more complicated than a simple choice of materials, involving ventilation, insulation, air sealing, etc. But our choices of materials havent made mold prevention any easier.

Blocked Or Insufficient Ventilation

5 Most Common Causes of Attic Mold &  How to Treat Them? in ...

The most common cause of attic mold, by far, is blocked or insufficient ventilation of the attic space. Attics usually have a passive ventilation system in which outside air comes in through the soffit/eave vents at the bottom, warms up in the attic, and escapes through the can or ridge vents at the top . That cycle creates a nice, breezy airflow and a well-ventilated attic. See this illustration:

However, we often see the soffit/eave vents blocked with insulation, thereby destroying the whole passive ventilation system. And when that system is destroyed, warm and humid air in the attic will stagnate, and often condense along the cold wood sheathing in the winter, causing wet wood and subsequent mold growth throughout much of the attic.

We also see mold growth in attics if there are not enough vents installed. Check your local building codes for whats required in your area, but in general, 1 square foot of venting is needed for every 100 square feet of attic space.

Any home inspector worth their salt will check a houses attic ventilation system. To pass an inspection, and to ensure that an attic stays cool and dry, make sure theres a proper system in place thats unblocked by insulation.

Knowing the proper signs of attic mold, and how to prevent it to begin with, can save you a major headache during the sale of your home.

Mold Remediation For Attics And Crawlspaces

Attics and crawlspaces are two common areas where mold is found in the home. Both are ideal for mold growth because of the presence of moisture, humidity, and wood for the food source.

Mold in the home can cause respiratory illnesses, skin, eye, and nose irritation. Once mold is in an attic or crawlspace, it can find a way into the living area of your home due to the natural air exchange in homes.

Mold is often caused by moisture accumulation in attics and crawlspaces from kitchen and bathroom fans that are not properly routed outside. It can also be caused by improper ventilation in your crawlspace or attic. To prevent mold from returning after remediation, these items need to be inspected and repaired if necessary.

Ultimately, if left unchecked, mold can cause poor air quality and can damage the structure of your home.

What are the signs of mold in your attic or crawlspace?

Smell of mildew One of the most common ways to detect mold is to use your nose. If you smell a musty, moldy smell, then mold is present somewhere nearby.

Stained wood Black or discolored wood is another sign of mold growth. It is a good idea to check your attic and crawlspace at least once a year for signs of mold. If you are not sure, our inspectors can help identify if mold is present.

Getting rid of mold growth

  • Our trained inspectors can help determine if mold is present and will come up with a comprehensive plan to remediate the area.
  • Prepare The Mixture To Vaporize

    4 Mix 1 teaspoon of white vinegar or tea tree oil with every cup of water you need to attack your mold colony. Tea tree oil and white vinegar are both completely natural and safe for wood, but have strong fungicide properties. Mix your vinegar or oil solution in a spray bottle and spray the mold in your attic. For heavy mold work, white vinegar may not be strong enough. In these cases, try mixing 1 part hydrogen peroxide with 2 parts water. Spray it and wait an hour. Peroxide is also safe and natural.

    5 Rub the attic with a firm metal brush and dry the area one last time. Remove any plastic sheets and repair any leaks or vulnerabilities to prevent new mold from appearing in the future.

    Reduce The Chances Of Mold With Proper Attic Ventilation

    One of the biggest causes of mold is having improper ventilation in your attic. This is intensified during the winter months when there is a significant amount of air coming in your attic versus going out. There is also a temperature variance that will create moisture buildup if not properly taken care of.

    The heat leaking out of your house and into the attic combined with the already cool or cold temperatures in your attic will cause condensation. This condensation if occurring for a prolonged period of time can lead to mold growth. The worst part of all of this is that how many times a year do you go in your attic? If you are like most people very rarely. This gives the mold ample time to grow and spread. Greatly increasing the likelihood that you or your family with possibly get sick with mold poisoning.

    Another important item to check is if you have a bathroom ceiling fan vent or even a dryer vent running directly into your attic. This will create and instant surge of moisture as the hot moist air is cooled by the attic air.

    Another important step is to seal up any gaps around pipes or chimneys that go through your attic. This is a critical place that air can escape into your attic.
