Transforming crawl spaces, our mold remediation services are dedicated to creating healthier homes. We tackle mold growth with advanced techniques like chemical-free dry ice blasting and ensure a ‘No Mold Guarantee’ for your peace of mind. With our expertise, we seal and encapsulate crawl spaces, moderating humidity and preventing mold regrowth.
Triangle Radiant Barrier is certified for mold inspection and remediation. Crawl space mold significantly degrades your home’s indoor air quality, can compromise the structural integrity of your home, and put you and your family’s health at risk.
We offer spray and fogging fungicide, HEPA Vacuum Scrubbing, Soda Blasting, and chemical-free Dry Ice Blasting. We also offer manual sanitization cleaning of your crawl space utility surfaces.
Chemical remediation is the most affordable option and is effective at killing light to medium mold. However, it does entail the use of chemicals which may be of concern to some homeowners. While there is no specific requirement to vacate the home during this method of remediation, it does contain sodium chloride with an order similar to bleach which may be an annoyance to some home occupants if present during or within a couple hours of application. Customer with sensitivities in this regard may want to have a ‘back-up plan’ to vacate the home during application, in case the smell is deemed as overly annoying. Wood-cleaning spray is often not effective against heavy mold staining / visible accumulation, especially on porous surfaces such as OSB plywood which is often used as subflooring and pony wall sheathing.
One of the best solutions to getting rid of the dangerous mold in your crawlspace is chemical-free Dry Ice Blasting, which blasts that harmful mold right out of your crawlspace.
Fogging fungicide inundates the entire crawl space to find and kill mold wherever it might be hiding. Does not, however, remove the mold’s visible accumulation or staining. Removal of visible accumulation requires either a mold-cleaning spray for blasting.
This method kills mold with fungicide and cleans treated surfaces with Soda Blasting. Effective at killing the mold, removing visible accumulate surface growth, and also removes about 70% of mold staining from wood. Provides a better aesthetic result than does HEPA Vacuum Scrubbing. Soda Blasting does leave a fine white dust residue (baking soda) on surrounding utility surfaces which may require separate cleaning but does act as a natural deodorizer.
Blasting at -110 degrees Fahrenheit, Dry Ice Blasting instantly kills mold and mildew on contact while simultaneously cleaning surfaces. There is no residue; dry ice sublimates directly from a solid to a gas. Dry Ice Blasting is effective at killing mold, removes visible accumulated surface growth, and provides the best cleaning of wood surfaces by removing 90%+ of embedded staining. Dry Ice Blasting is unique in that it is a fully chemical-free mold remediation method. If anyone in your home has sensitivities to chemicals or if you just like the idea of no chemicals being used under your living space, Dry Ice Blasting is the way to go!
After our crawl space mold remediation work is done, we highly recommend you have us seal / encapsulate your crawl space. Crawl space encapsulation with environment conditioning will moderate relative humidity such that mildew and mold will not be able to grow. We offer our ‘No Mold Guarantee’ which will guarantee against the regrowth of mildew or mold in your crawl space (terms and conditions apply). Contact us for details.
Here in the RDU / Triangle area of North Carolina (Raleigh, Durham, Chapel Hill, Cary), our climate is very humid, which is one of the key ingredients for mold growth in a crawlspace. The other contributing factors include limited airflow, no direct sunlight, moderate to hot air and high air relative humidity. The only way to avoid getting mold and mildew in your crawl space is to properly seal it / encapsulate it and add environmental conditioning, which includes air induction and/or dehumidification.
Current science shows that around 40% of the air we breath in our homes originate in our crawl space. If your crawl space has mold and mildew in it, there is a very good chance you are breathing in mold spores everyday.
In fact, an average vented crawlspace has such poor-quality air that finding mildew, mold, rust, wood rot, deteriorated fiberglass insulation, pest urine/feces/corpses, dust, pathogens, and decaying organic matter in the crawlspace soil is, unfortunately, quite common.
This poor-quality air moves up into your home via the stack effect (natural movement of air upwards through a home) and can saturate your crawlspace-installed HVAC ducts and components.
The only way to keep the mold that forms down in your crawl space from getting into your home is to seal the crawlspace completely. The benefit of a sealed crawlspace is that it moderates relative humidity which inhibits mildew, mold, wood rot and rust.
When sealing a crawlspace, the fiberglass insulation that is often found there is removed and no longer present to be an air quality deterrent. A sealed crawlspace also blocks ingress points that pests like insects, rodents and snakes use to get in and out of your Raleigh, Durham, Chapel Hill, Cary residence.
Furthermore, a high-quality vapor barrier will also guard against nasty vapors that can come up through the ground. We can further alleviate bad odors by applying a natural deodorization spray comprised of non-pathogenic bacteria and enzymes that are specially designed to consume (not just cover) any decaying organic matter that may be present under your vapor barrier.
Here’s a Before and After picture of a crawl space we sealed in Raleigh, NC:
Mold will grow in any space that has relatively high air moisture, warm to hot air, stagnant airflow, and no direct sunlight. All of these are present in crawl spaces in humid climates and why vented crawl spaces in humid climates are so susceptible to mold.
Yes. In homes with vented crawl spaces, up to 40% of the breathing air in a living space originates in the crawlspace. The is due to stack effect (the natural movement of air ‘upwards’ through your home) as well as leaks in return HVAC ducts in the crawl space.
Once mold is present, it will continue to be present and grow until it is remediated and the environmental negative conditions rectified. Mold consumes organic matter, such as wood framing in homes which will increasingly compromise the structural integrity of the home, if left unchecked.
Crawl space mold remediation is generally conducted in two ‘phases’: 1) killing the mold and 2) removing the visible, accumulated mold growth on the treated surfaces and potentially the mold staining embedded in the surface as well.
Killing mold requires the application (typically spraying or fogging) of a chemical fungicide or using a specialized process such as Dry Ice Blasting (killing mold with extremely cold temperature).
Removing the visible, accumulated growth from the treated surface is typically done with HEPA Vacuum Scrubbing, Soda Blasting (pressure cleaning with high pressure baking soda), or Dry Ice Blasting (pressure cleaning with high pressure dry ice).
Proper personal protective equipment (PPE) is mandatory. A HEPA Air Scrubber, sometime assisted by ventilation fans, is needed for all but very small remediation jobs. Any crawl space installed HVAC equipment should be turned off and left off for the duration of the remediation process.
Dry Ice Blasting offers the most effective performance for crawl space mold remediation in terms of not only killing the mold and removing the visible, accumulated mold growth on the treated surfaces but also in removing the staining that the mold left in the treated surface. Dry Ice Blasting can typically remove about 90% of staining from wood surfaces such as crawl space joists and subflooring. Dry Ice Blasting is also chemical free and residue free.
Soda Blasting (with fungicide pre-treatment) is fully effective at killing mold and removing the visible, accumulated growth on treated surfaces, and will typically remove about 70% of the staining from wood surfaces. Soda Blasting does leave a fine white dusting of soda residue in the crawl space with does help as a deodorizer but may leave you wanting for aesthetic wipe cleaning.
HEPA Vacuum Scrubbing (with fungicide pre-treatment) is fully effective at killing mold and removing visible, accumulated growth on treated surfaces. It will not remove any staining embedded in wood surfaces.
