5 Warning Signs It’s Time For A Vapor Barrier Installation


Crawl spaces are one of the most important parts of every building. Unfortunately, homeowners hardly consider them when thinking of renovating their homes. As amazing as crawl spaces are, if care is not taken, they can always cause various structural problems in your home. One factor that causes these problems is crawl space moisture.

Today, it costs a lot of money to address moisture problems. Because of this, it’s often advisable for homeowners to inspect and control moisture in their crawl spaces quickly before they cause costly issues. Today, vapor barriers or retarders are one of the most effective ways to control crawl space moisture issues. But when exactly should you consider using a vapor retarder?
