IS YOUR HOME’S STRUCTURE SAFE OR IS DECAY HIDDEN BEHIND YOUR WALLS?

Poria Incrassata: Infestation

Poria Incrassate is a wood-decaying fungus belonging to a group of fungi referred to as the “brown rot family,” which differs from the other members of this family by its unique characteristic that it provides its own moisture. Although it is rare, it is often mistaken for mold or rot. The difference is it attacks a home’s wood framing members, causing instability problems for your home’s structure, ultimately increasing the liability risk for injury or collapse occurring.

The main destructive feature of this fungus is that it is its own moisture source. The excess water that may be found in the soil beneath and surrounding your home’s foundation may be the start of significant structural damage and the inevitable decay and collapse of your home’s support beams, exterior wall framing, wood siding, roof framing system, decks or patio covers if Poria is present. Poria can travel at any given depth in search of moisture in the soil. Therefore, Poria cannot be removed from the soil it infects.

Because Poria brings its own water source, the initial damage noticed may appear to be similar to water damage such as on a wood floor that begins to buckle or cup and eventually caves in. The second stage of Poria eating the wood support members materials beneath the wood flooring materials may look similar to wood rot as the wood product is broken down to a white chalk or dust-like consistency as it eats floor joists, wood framing members and the wood flooring material. Once it eats the wood materials, there is no evidence or remnants of the wood materials that were once there as they appear to have vanished. What appears to be the collapse or caving in of the flooring is actually the result of the support beams or sub-floor’s complete disappearance due to the Poria.

According to Southern California Poria Incrassate Specialist, J. Luis De La Cruz from Wood Preservation Services, you cannot successfully test to confirm Poria Incrassate. Testing for Poria requires obtaining “live” samples of decay fungi from the infected wood. Removal of a piece of wood infected by Poria for testing in a lab or to take a sample from the site and place it in a petri dish disconnects it from its moisture source, which is the one thing that sustains its life. This also allows other more prominent bacteria from the air to show up in the test results rather than the Poria as it is no longer living. Testing will only conclude that Poria is from the “brown-rot family” of fungi, however, there are hundreds of strands that fall under this category. Therefore, incurring costs for lab testing fees (these can range from $900 - $1,500.00) to confirm the presence of Poria is pointless. The important thing is to ensure that there are no wood members that come in contact with the soil and that there is enough space separating the home’s wood framing or siding from the soil.

Vigorous poria growth can result in water damage:

Poria is commonly mistaken to be the result of a water intrusion issue. If not recognized in a timely manner, Poria will continue to cause damage to the home’s structure unbeknownst to the homeowner until a collapse occurs after the wood support or framing members are completely eaten away.

Once Poria is established, it continues to be active in the soil year-round and produces reproductive fruiting bodies twice a year (mainly in May and November). During its reproductive stage, Poria can transport moisture into the colonized area from an astonishing 150-foot distance, which makes it impossible to locate its original source. The consumption of wood then increases and millions of spores are produced. Because Poria secretes its own enzyme onto the wood, the wood eventually turns to mush. The affected wood components become saturated, exceeding the wood’s capacity to retain water. The excess water can be found pooling within the infected area, causing water damage to the building materials. The spores are a dark reddish brown film and are expelled with tremendous pressure, making them airborne, covering the flat surfaces around the infected area. As long as the supply of water is available for the Poria, the water-conducting fungi can colonize and decay the wood of the entire structure. The bad news about Poria is that it’s hidden and it spreads fast. The good news is, once you find it, it’s growth can be controlled and ultimately stopped completely once proper construction design is put in place.

Homeowners beware: Poria Incrassate can cost you tens of thousands of dollars in repairs if it is not recognized timely. Given that Poria is considered a mold or fungus, many insurance policies exclude or limit coverage for removal of building materials damaged by Poria and any repairs needed to replace the affected materials. If Poria is not correctly identified in the initial investigation stage of the claim, your homeowner insurance company may exclude coverage entirely due to Poria’s resemblance to rot, which generally is not covered by insurance due to it being a long-term issue.

The Solution: add concrete footings or a concrete stem wall around your home’s foundation to prevent the Poria from coming in contact with wood posts and framing members and make sure there is at least a 4-inch gap between the soil and the base of any wood siding or wood materials. Once the infected wood is removed, the Poria strain dies as it no longer has access to its source of moisture in the soil. However, if the construction design is not changed that allowed the Poria to come in contact with wood materials of the home and the Poria still has a moisture source, it will attack the new wood materials that replaced the previous infected ones that were removed.

Poria Incrasta: From the Expert

IS YOUR HOME’S STRUCTURE SAFE OR IS DECAY HIDDEN BEHIND YOUR WALLS?

Poria Incrassata: Infestation

Poria incrassata is a wood-decaying fungus belonging to a group of fungi referred to as the “brown rot family,” which differs from the other members of this family by its unique characteristic that it provides its own moisture to the wood to be colonized through water-conducting strands called rhizomorphs.  Because the rarity of its presence and the lack of knowledge by the consumer and service providers, it is often mistaken for mold. The damage is most-often mistaken as that caused by other members of the family as the damage is identical and is commonly referred to as “dry-rot.”

Extensive damage to the floor structure and wall framing could exist before the first signs of the infection become evident to the occupants by the emergence of “fruiting bodies” or by hardwood floors cupping, buckling or breaking, as well as baseboards and door jambs shrinking and disintegrating.  It is not rare to find the presence of Poria as a result of the sudden collapse of sections of the floor, which on some occasions have resulted in injuries to the occupants.

This destructive feature is as a result of its ability to obtain moisture from the soil and transport it to the wood by the rhizomorphs that will gain access through separations between building components, cracks in the foundation or in many occasions due to direct contact between the soil and the wood members( like on the porches where the earth fill may be higher than the wood.)

Keeping the wood wet is essential for the Poria to continue its growth and often results in the improper assumption that the cause of the “dry-rot” is as a result of water intrusion caused by leaks (roof, plumbing, sprinklers, grading, insufficient ventilation, etc.) leading to unnecessary expenses. This also often results in improper repairs that will allow the infection to re-start as soon as the replacement of the affected building materials are completed.

Vigorous Poria Growth Can Result In Water Damage

The visible damage observed due to Poria often confuses the homeowner and the service providers, leading them to believe that external sources are the culprit, due to the degree of saturation on the wood, insulation in the walls or the floor, water running out of the joints of the siding or small puddles at the base of the wall, or floors buckling or cupping.

It is a common mistake to think that the irrigation of the landscaped areas have to do with the source of the Poria infection, as it will travel far and deep to find moisture. Given this fact, it impossible to determine the original source of the infection.

Once Poria is established, it continues to be active in the soil year-round and produces reproductive fruiting bodies twice a year (mainly around the months of May and November).  During this stage, the consumption of wood is increased and millions of spores are produced and expelled with tremendous pressure, making them airborne, resulting in a reddish brown film covering the flat surfaces around the infected area.

A Poria infection begins from a microscopic spore and the development of microscopic filaments that eventually will gather together to form a visible strand (rhizomorph) that may grow to inches in a round form (similar to a root) or flat when compressed between building components. These stands can reach a size from ½-inch thick to several inches wide.

The identification of Meruliporia (Poria) incrassata should be based on the observation of the characteristics of the infection at the site like the presence of fruiting bodies, the presence of spores, the mycelium growth, the spread of the infection, the presence of fungus moths and more than anything else, the presence of rhizomorphs.

A Poria infection by its own nature creates a favorable environment for the growth of other types of fungus (mold) and other opportunistic bacteria, as the supply of moisture is constant until the rhizomorphs are detached from the wood.

Laboratory testing based on air samples may show the presence of Basidiospores that indicate the presence of wood decay without identifying the genus. Bulk samples will be contaminated with ever-present floating spores of everything, so the growth in a petri dish may show everything except Poria, given that Poria will die once disconnected from its water source.

If you choose to have a lab test for Poria, you’d better have deep pockets. Lab testing fees can range between $900.00 - $1,500.00, and will likely not be able to confirm anything other than a mold from the “brown rot family.” Lab technicians or hygienists are not trained to identify where the Poria are gaining access to the structure.  A better investment would be to hire an expert who is knowledgeable about the characteristics of the Poria infection to inspect, determine the conditions that are providing access and contributing to the Poria infection as well as the type of repairs necessary to eliminate those conditions.  In most cases, these inspections are less expensive than the lab testing fees, which ultimately, do not remediate the source of the problem.

Homeowners beware: Poria incrassata can cost you tens of thousands of dollars in repairs if it is not recognized timely or if the repairs made are inadequate.  Given that Poria is a wood decaying fungus and it is grouped with the non-wood decaying fungus or MOLD, many insurance policies exclude or limit coverage for removal of building materials damaged by Poria and any repairs needed to replace the affected materials.  If Poria is not identified correctly in the initial investigation stage of the claim, your insurance company may exclude coverage entirely. This isn’t unlikely as the damage by Poria is commonly referred to as “dry rot”, which is a misnomer for wood decay and is generally not covered by insurance due to it being considered a long-term issue.

The Solution:  A proper inspection by a professional with knowledge about Poria incrassata will determine the type of repairs that will be necessary to eliminate the current activity and to eliminate the threat of future attacks.  Demolition of certain finished surfaces may be necessary to implement resolving the problem.  Concrete barriers could in some cases aggravate the situation if the access route is not located and sealed properly.  The repairs will vary depending on the details of the construction of the home’s structure as homes with a crawl space differ from those with concrete slab foundations and they require different approaches to solve the problem.

The repairs must fallow a sequence where the points of access are found and eliminated, wood is replaced, and may require that additional barriers be applied. In addition, the interior and exterior materials must be completed providing separations or air gaps between the soil and hard surfaces, such as at the base of stucco or siding.  Decorative veneers on the exterior of walls may have to be eliminated unless special provisions are incorporated in the repairs.

Once the rhizomorphs are removed from the wood, eliminating the source of moisture, any activity above that level will cease as the infection will die and it will not regenerate new growth even if the area gets wet by external sources.  Wood with growth on the surface can be left in place if not structurally weakened with the growth left in place or scraped off depending on your preference.

Poria is a soil inhabitant organism and it will continue to be active as there are no chemicals that will control its growth.  Performing the proper examinations and applying the proper seals to isolate the wood frame from access by the rhizomorphs is the only solution to prevent its attack.  The source of moisture being the soil will always be present regardless of the depth at which Poria will have to travel to obtain it.  If you have water damaged floors, it might save money in the long-run to investigate the possibility that the damage could be as a result of Poria activity.

Are Mold Monsters Lurking in Your Home?

It’s that time of year again when ghosts, goblins and monsters can be seen everywhere on Halloween. We all know these monsters are not real, so it’s fun for both adults and children. However, there may be a real monster lurking in the depths of your home and you may have no idea it exists! No, we’re not talking about your children playing hide-and-go-seek in the closet – we’re talking about mold. 

Heavy rains and large (or even small) leaks in your home can cause mold to grow inside of the wall cavities or behind the cabinetry in your home. With the rainy season approaching, homeowners need to be aware of these sneaky leaks because they can cause major mold problems if left undetected.

Mold spores are found everywhere, as they are a common component of household and workplace dust. However, when spores are present in large quantities, they can be ghastly health hazards to humans. These spores potentially cause allergic reactions and respiratory problems.

According to the EPA (Environmental Protection Agency), 100% of all types of mold have the potential to cause some health effects. Exposure to high levels of mycotoxins can lead to neurological problems and in some cases death. Prolonged exposure can be particularly harmful. So what may appear to be harmless discoloration on your walls behind furniture or black spots growing on the walls and ceiling of your bathroom may likely be an issue that needs to be addressed before any of the exposure causes any harm to you or your loved ones.

Symptoms of mold exposure:

• Nasal and sinus congestion, runny nose, nose bleeds 
• Eye irritation, such as itchy, red, watery eyes 
• Respiratory problems, such as wheezing and difficulty breathing, chest tightness 
• Coughing 
• Throat irritation 
• Skin irritation, such as a rash 
• Headaches 
• Vomiting 
• Sneezing / Sneezing fits 

These are signs you can possibly have a hidden mold monster growing in your attic, crawlspace or behind your walls. If you notice any of these symptoms, don’t simply excuse them. According to the Mayo Clinic, 93% of chronic sinus infections have been attributed to mold. Mold spores can be spread throughout the home by your HVAC system. According to CNN Money, over 30% of brand-new homes built have mold of some form in them.

Often times, there is not a visible water source, obvious leak or visible discoloration to indicate the presence of mold growth may be lurking behind walls or cabinetry.

What can you do to protect your investment?

- Investigate any musty, foul or unusual odors in your home and address repair of water leaks in
a timely manner

- Check for any signs of water staining on cabinets and shelves, dripping of water from the hot
and cold angle stops and p-traps located beneath kitchen and bathroom sinks

- Look for discoloration on the floor around the base of toilets or the walls and cabinets next to
toilets

- Review your water bill for any significant increase

- Water pooling on the outside of your home may be a sign of a plumbing leak

- Paint on your walls that starts flaking off or chipping may be a sign of a water problem

- Mushrooms or white, green, or black fuzzy growth on carpets, walls or furniture are mold

- Look for discoloration or stains on your walls or ceiling which may be due to a roof, air
conditioner unit or plumbing leak

- Discolored tile grout, warping of wood flooring, or curling of vinyl tile or linoleum are often
signs of moisture or water

- Replace washing machine hoses that are deteriorated or are more than 5-years old

- Check for water staining on or around the water heater platform or rust on the hoses at the
top of the water heater

- Look for stains or discoloration at the base of kitchen cabinets or toe-kicks near your
dishwasher or refrigerator

- Spraying or wiping mold allows the mold spores to become airborne and inhaled

- Do not place fans in areas where you suspect there may be mold as this can blow mold spores
throughout your home

- Tape down a sheet of plastic over the visible mold area and call a professional to remove it

- Infants, elderly people and people with low immune systems are more likely to be adversely
affected by mold

- Open a window when running the shower if you don’t have a fan in your bathroom

Call SOS:

- For referral of reputable plumbers who can investigate to confirm if you have a leak or water
intrusion issue

Dealing with Minor Mold Growth on Your Own

If you encounter small patches of surface mold and feel like you can remedy the problem without calling a contractor, follow some of these DIY tips and preventative measures suggested by Specialized Outsource Solutions. Remember, if it seems like too much to handle, you’re probably right. Always defer to professionals to help keep yourself and your home healthy.

• The most common type of surface mold: Mildew (it grows most often in your bathroom, in the form of small black spots, and can easily be remedied on your own)
• Scour small patches of mold with boric acid (wear gloves and goggles)
• Avoid using ammonia in your cleaning products, as it can be poisonous 
• Create your own cleaning solution to scrub out mold: Mix lemon juice and water together, as it can be a natural, more pleasant-smelling alternative to bleach and other cleaners
• Bleach is most effective on mold growth appearing on impervious surfaces (like grout, concrete, tile, etc.)
• If you see mold on wood, take a screwdriver and try to scrape the very top surface. If it seems like the mold has softened the wood further down, it’s likely rotted to the point where your own remedies may not be able to fix it and the wood may require replacement
• Use paint with mildewicide (found at home improvement stores), especially in damp rooms like bathrooms and laundry rooms
• Clean your ventilation systems: These are prime spots for mold growth, dust mites, and germs
• Keep up with normal household chores: Mop up spills and puddles the moment they occur, scrub bathrooms with commercial cleaner and prevent surfaces from staying damp
• Immediately tend to burst pipes and keep drains unobstructed 
• Routinely check attics and other non-frequented places for signs of mold, musty smells and water stains 
• Items stored in attics (and basements) should be in air-tight containers or bags to create an extra barrier against moisture
• Remember: Some molds can be very detrimental to your health. Always wear protective gear when working on your own to rid your home of mold and always use a professional when needed.

If the visible area of mold is more than 10-square feet or if you think your mold problem is too much to handle on your own, do yourself a favor and see what a certified contractor will say. Specialized Outsource Solutions (SOS) will refer you to reputable and certified professional contractors in your area that specialize in mold removal.

There's mold in my home: When should I call a professional?

Mold found in homes can sometimes be remedied with a simple do-it-yourself (DIY) fix. However, when homeowners encounter large masses of mold growth, a contractor with legitimate certifications and experience is of utmost importance in order to avoid further (and more costly) damage and potential health problems.

Q: When should professional contractors step in? 
A: When mold begins growing in large quantities, the surface it’s growing on cannot be repaired with a DIY method, and its source (like a severe pipe leak) cannot be repaired without the help of a professional.

Certified contractors generally begin a mold remediation job by running lab tests to identify the type of mold on the scene. A remediation contractor will then define the best process to address the situation and commence work to remove or clean the affected area(s).

Homeowners dealing with significant amounts of mold will often need to remove drywall or discard moldy carpeting simply because it's impossible to clean. The removal process is sensitive; if a contractor is not well-versed or certified, they may further spread mold spores in the removal process. This can lead to additional remediation work and can trigger health issues, such as mold allergies. Always rely on professional workers to get the job done right the first time.

When it comes time to bring a professional mold contractor into the job, call Specialized Outsource Solutions for referrals to certified professional companies in your area. Speak with their customer service team at 888-589-1868 any day of the week, any time of day.
