Vapor Barrier Repair & Installation

What is a vapor barrier?

A vapor barrier is a special plastic sheet that goes under a mobile home to help keep moisture out. Because mobile homes sit above the ground, damp air and water from the soil can rise up and cause problems. Over time, too much moisture can lead to mold, mildew, and even wood rot, which can weaken the floor and the structure of the home. A vapor barrier helps stop this by keeping the space underneath the home dry and protected.

Too much moisture can also make your home less comfortable and more expensive to heat and cool. When insulation under the home gets wet, it doesn’t work as well, which means your home could feel colder in the winter and hotter in the summer. It can also lead to rust on metal parts and even musty smells inside the home. A vapor barrier helps keep the insulation dry, improves air quality, and makes your home more energy efficient, which can save money on utility bills.

Installing or replacing a vapor barrier is an important step in taking care of a mobile home. It helps prevent costly damage, keeps floors strong, and protects against mold and dampness. Whether your home is old or new, adding a vapor barrier is a smart way to make sure it stays in good shape for years to come.

How do I know if my vapor barrier needs to be replaced?

If you see tears, sagging, or missing sections under your home, it may be time to replace the vapor barrier. Signs of moisture problems inside, like musty smells or soft floors, can also mean the barrier isn’t working properly.

Can I install a vapor barrier myself, or should I hire a professional?
