Why do you need a vapor barrier?
WHAT IS A VAPOR BARRIER?
A vapor barrier is basically a thin layer of impermeable material, included in building construction to prevent moisture from damaging the fabric of the building.
The employed materials are usually roofing paper or polyethylene film, and their main role is to retard or prevent the absorption of moisture into a wall or a floor.
Moisture control is one of the biggest challenges that every homeowner has. If not controlled, it can cause indoor air quality problems, which affects water heater durability, efficiency and HVAC ductwork.
It can also create the perfect environment for wood destroying organisms, which could affect the effectiveness of your insulation and could promote wood rot.
People how have their homes built over crawl spaces should pay extra attention, because of its conditions it is easier to experience moisture problems.
HOW DO I KNOW IF I HAVE MOISTURE CONTROL ISSUES?
Easy, look to see if you have water collecting on the pipes or concrete walls in your crawlspace. If the answer is positive, then you’re experiencing a common problem and you should fix it as soon as possible.
Adding high quality and permanent vapor barrier is one fairly easy solution that will correct your crawl space problem.
In certain climates vapor barriers can be a vital part of construction. Also, if you live in a hot and humid climate city, it is way easier to experience moisture control issues in a certain moment.

Installing a crawl space vapor barrier isn’t a complicated or expensive job. However, incorrect use can lead to additional moisture problems. That’s why you should know a few pro tips before doing it:
PRO TIPS YOU SHOULD KNOW BEFORE INSTALLING A VAPOR BARRIER:
- Locate your crawl space entrance properly. The entry hatch to a crawl space is not always easy to find. It is sometimes located outdoors or along the perimeter wall.
- Attack and stop all drainage and combustion problems and dry our the crawl space leaving it as dry as possible. You can start using a dehumidifier, set up fans, remove wet materials, and use a pump to discharge any standing water.
- Clean the crawl space. Remove all debris, especially anything sharp that might puncture the plastic.
- Make sure to remove all the mold and mildew within the area, if applicable.
- Attach plastic sheets to walls and piers. The goal is to provide a solid barrier against the ground.
- Extend the vapor barrier up the wall, 6 to 12 inches above outside grade.
- Improve ventilation. The vapor barrier will prevent most water from getting into your crawlspace, but you should definitely improve cross ventilation as an additional method that will help prevent any residual moisture from being trapped in the space.
- If you feel that you are needing an extra reinforcement to avoid moisture, crawl space encapsulation is a great option.
