Another company has offered to put a vapor barrier in for less money, why should I use Triangle Crawl Space Solutions?

Your pest inspector or HVAC provider may offer to install a vapor barrier, just be cautious of what you are getting. These companies do not specialize in crawl spaces and may not correctly identify moisture issues or potential damage. Depending on your specific needs a vapor barrier may only be a first step in solving your moisture problems.

Triangle Crawl Space Solutions focuses solely on solving moisture issues and correctly protecting your home. Other companies offer these services as an add-on.

Additionally Triangle Crawl Space Solutions is fully insured and dedicated to paying our employees a Living Wage. Crawl spaces are what we do and we take pride in doing a through assessment for all of our customers and answering any questions or concerns.

Is it normal to see black dots of mold on floor joists?

Common molds are present in almost every crawl space. Minor spots of mold on floor joists may not be an issue but it is important to fully inspect your crawl space for hidden areas of more extensive mold (Which can develop into dry-rot), standing water, hidden plumbing leaks or other problems under your home.

A full inspection of your crawl space is the best way to determine if your have any moisture problems. Many issues may not be visible from a quick peek inside your crawl space door.

I have hanging or fallen insulation, does it need to be replaced?

This depends on whether the insulation has become wet or moldy. If the insulation is dry it can often be rehung or a damaged portion can be replaced. If your insulation is wet, moldy or a low R-value, it should be replaced.  Current NC code specifies R19 insulation. If your home is older it may have R11 between floor joists and we recommend upgrading to R19 for maximum efficiency.

I’m getting ready to sell my house, what should I do?

We encourage homeowners to give us a call for a free assessment BEFORE they schedule any home inspections, etc.

It is better to know and identify any moisture issues before they become a red flag to potential buyers. Standing water or excessive mold in your crawl space send up an immediate red flag and fallen or hanging insulation is often listed on a home inspection report.

Triangle Crawl Space Solutions can assess your crawl space and make recommendations to have your crawl space in tip-top condition before these issues become a problem for potential buyers.

How thick does the vapor barrier need to be?

Vapor barriers should be at least 6mm in thickness to effectively cover the area and create a moisture barrier. Triangle Crawl Space Solutions uses both a 6mm material for simple vapor barrier installation and a thicker more durable 12mm vapor barrier material depending on the budget and needs of the home.

More common that an issue with the thickness of the vapor barrier is making sure that the vapor barrier is properly installed and is covering the entire area under your home. If the vapor barrier doesn't extend all the way to foundation walls or has gaps in the coverage then moisture simply moves around the barrier and impacts the uncovered area.

What about access for Termite and other pest inspections?

One of the concerns about installing a sealed vapor barrier or encapsulating a crawl space is what do do to allow access for termite and other pest inspections or treatments. Pest control companies need to be able to both inspect and treat areas under your home so must have clear access to areas where floor joists and wooden sill boards meet the concrete or block structures.

This is the reason that all of our vapor barriers and foamboard insulation panels always stop at least three inches from any wooden structure. This allows pest companies to both inspect and treat any possible problems. In general encapsulating or sealing your crawl space reduces the number of pests (both insect and rodents) under your home by removing moisture and eliminating habitat.


When is mold remediation recommended?

Mold remediation is recommended when your home is showing signs of mold causing potential dry rot to the structure of your home or if it is causing health and/or indoor air quality issues that are impacting your family or health.

Our technicians can evaluate any mold under your home and make recommendations that will determine if you need actual remediation procedures or if you simply need to control any moisture underneath the home.

Mold requires a damp or wet environment to grow so controlling moisture will naturally reduce mold in your crawl space. Depending on the severity of mold under your home it may be simply a matter of stopping the moisture that allows mold to continue to grow and develop.

If there is extensive mold under your home or it has begun to dry rot the wood structures then remediation may be required.

Is 50% of my indoor air really coming from my crawl space?

There is a lot of discussion about crawl space air polluting the air inside your home. Some claims say up to 50% of the air in your home is "dirty" crawl space air.  While for certain there is some air transfer between your crawl space and your home, the 50% claim is exaggerated and doesn't account for insulation, flooring, and other barriers that are in between your crawl space and your living spaces above.

This claim is mostly based on something called the stack effect. Everyone understands that hot air rises and cool air falls. The stack effect is most often associated with how draft works in a chimney but also can be applied to how air moves through your home. In the winter, warm air rises first to your second floor and then is lost through leaks in the roof and ceiling insulation, this change in pressure pulls air through your home to escape at the roof. In the summer the process is reversed as cooled air from the HVAC system seeks to "fall" as a result pushes warm air upward. This is why upstairs bedrooms are hotter than lower levels in the summer. In both seasons, this change in air pressure pulls air from the lowest point, your crawl space, so there is some air transfer but a claim of 50% is drastic.

If your crawl space is musty smelling, dirty and moldy and you are experiencing the same musty odor or seeing health related issues with mold or asthma inside your home then certainly your crawl space might be one place to start addressing this problem.



What sort of maintenance does my dehumidifier need?



One installed and properly adjusted your Santa Fe dehumidifier will need a filter changed about once a year. If you can change the air filter in your HVAC system then it should be no problem to DIY your dehumidifier filter. Filters for the Compact 2 model can be purchased from Triangle Crawl Space Solutions or online here.
