Depending on the soil, home construction, venting, etc., homes can rapidly be exposed to crawlspace mold contamination. With over 40% of the home’s interior air coming from the crawlspace, it is important to keep the humidity in these areas within acceptable limits. A typical 1000 sq ft crawlspace can produce as much as 10 gallons of moisture every day, rising into the home. Our company will evaluate and test the cavity for any existing problems, treat and eliminate mold issues with warranties up to 30 years, and install de-humidifiers or full sealed encapsulations, should your situation require it. Again, each home is different, and we only recommend the solutions that best fit your circumstances.
Depending on the severity of the mold, many methods of remediation will be explored. Some are non-invasive, with anti-microbial scrubs to remove the mold. More severe cases require that the contaminated materials be removed. At PES, we make quality and safety our top priorities when working a demolition or restoration project. We follow strict IICRC S520 protocol, including containment, for the protection of the home owners and our employees. We use only ANABEC mold products, providing warranties up to 50 years.(see our products page for details). We can do as much or as little of the re-construction work as you would require.
Crawlspace Moisture Control
No mold treatment can be successfully executed without first identifying and correcting the moisture source. BEFORE ANY QUOTES ARE MADE, we find the moisture source. Using hygrometers, protimeters, and borascopes, we identify and correct the moisture problem before any mold remediation begins.
Once a crawlspace encapsulation is complete make sure that you have a solid insulated door installed. You don’t want to have a great project ruined by an insufficient crawlspace door.
We recommend that the crawlspace door be 4 inches above the outdoor ground level, this prevents rain water infiltration. We also recommend that the door be constructed of a material that isn’t corrosive.
Proper debris removal is a very important, sometimes overlooked, step in laying a good vapor barrier or doing a full crawlspace encapsulation. A nail, piece of lumber, or rock in the wrong place can cause water to pile up or a tear in your vapor barrier.
When the moisture levels in a crawlspace go unchecked for an extended period of time wood rot begins to occur. Ideally PES Crawlspace will be contacted about a potential moisture issue long before wood rot begins to present itself, in the cases that wood rot is already present we are equipped to remedy the issue. We are equipped to handle small repairs such as floor joists repairs to sill plate replacement.
Many of our estimators were in the construction industry long before the mold business and all of our certified technicians have previous experience in construction. In fact our entire operation is based on the mindset of a contractor, not a crawlspace dry out company.
This allows us to look at issues from all angels and not just a single minded view point. This also allows us to be the only company you need to talk to when it comes to your crawlspace repairs. We don’t do electrical, plumbing, or pest control. We do however work with some of the best of each of those industries and manage the entire project for you to ensure its completion. If you would like to manage your own project then we will simply give you a list of referrals that we know do good work.
What is a Vapor Barrier? A vapor barrier is simply a thin layer of polyethylene sheeting, plastic, typically ranging between 4 mil and 30 mil in thickness. Local building codes recommend a minimum of 6 mil poly be used in crawlspaces, we at PES Crawlspace feel that you get a longer last product with a 10 mil reinforced and that is what we recommend
The purpose of a vapor barrier is to control the amount of moisture being released into the air from the dirt ground of the crawlspace. In an open or vented crawlspace a vapor barrier is not designed to prevent on moisture, it is designed to slow down the amount of moisture released into the air. When the amount of moisture being released into air of the crawlspace is slowed down it better allows the natural airflow from the foundation vents to adequately dissipate the moisture out of the crawlspace.
Any thickness of poly will achieve the same results in regards to controlling the amount of moisture being released into the air from the crawlspace floor. The only difference in the thickness of plastic being installed is durability. The thinner the plastic the greater the chance for the plastic to be torn, pulled loose, or damaged when people are working in the crawlspace. When pest control companies, plumbers, cable providers, and other people enter your crawlspace they disrupt what is there. If the plastic you use is too thin and damaged then you can lose the benefits of having the vapor barrier.
PES Crawlspace recommends using a 10 mil in most circumstances for crawlspace vapor barriers. As long as you keep the minimum thickness at 6 mil it is really up to you on the thickness of material you use for the vapor barrier. A reinforced 10 mil poly will hold up over time and isn’t overkill for your project, ensuring that you get the most bang for your buck!
To sum it up simply think of a vapor barrier as a time-release mechanism that allows the natural airflow provided by your vented or open crawlspace to efficiently keep the space dry.
The 10 mil vapor barrier that PES Crawlspace uses is 100% reinforced and won’t grow mold. Many of the 10 mil reinforced vapor barriers on the market today are only 10% reinforced. In fact, the 10 mil that we use is actually comparable to most 20 mil reinforced liners. The 10 mil reinforced liner that we use is white and gives a very clean finish when complete.
This is our premium liner for crawlspace floors. The product was custom designed for crawlspaces with a padded felt bottom that distributes any water and soil gases below the vapor barrier. It is triple reinforced and puncture resistant. The vapor barrier is actually designed to help move and disperse moisture evenly to drier areas.
The top side is coated with an extrusion and laminate for additional strength. The top coating of the premium 30 mil vapor barrier is matched to the seam tape we use in order to maximize adhesion to the liner. The clear seam tape is invisible when pairing with the premium 30 mil vapor barrier.
We will provide you a sample of this product upon inspection of your crawlspace so you can see its amazing benefits yourself.
The crawl curtain is a 12 mil vapor barrier adapted for vertical installation on a foundation wall. It is lightweight and extremely workable, making it a great choice for sealing foundation walls and piers.
What makes the crawl curtain unique is the activation strip built into the top of the curtain. A bead of polyurethane adhesive is place on the surface you want to attach the curtain to. Remove the cover from the activation strip, attach to polyurethane adhesive and apply pressure. Within 24 hours you have a permanent bond to the surface.
No mechanical fasteners are required and the sealed bond is better and stronger than anything else on the market today.

Seam weld is used to attach the floor liner to the wall liner or wall insulation board. Seam weld creates a much stronger bond between the floor liner and wall than any seam tape could. In fact, once the seam weld is attached and cures for 24 hours it becomes a permanent bond.
A French drain installed correctly and in the correct location can do an excellent job of preventing excess water from entering your crawlspace.
A French drain is trench filled with gravel and a 6 inch perforated pipe. A properly designed French drain system will redirect surface water from heavy rains away from your home. If you have an issue with excess water getting into your crawlspace this may be the answer for your home.
Southerners are no stranger to humid heat. It’s uncomfortable and can leave you and your family exhausted. But did you know that humidity can also be dangerous? Humid conditions in your crawl space can create a breeding ground for harmful and dangerous mold. We offer Aprilaire whole-home dehumidification solutions to help improve the comfort and safety of your home.
It is important to keep your crawl space well ventilated and dry to prevent liquid build up and mold which can be damaging to your property and health. The ATMOX crawl space ventilation system uses sensors to measure the humidity both within your crawl space and outside of your home. With these readings, the system is able to ventilate your crawl space with outside air only when it is beneficial to do so. Combining the system with an optional dehumidifier can be a great way to improve the quality of air in your home and prevent damaging mold.
