Factors that Affect Crawl Space Encapsulation Cost



The location of your home plays a role in determining your crawl space encapsulation costs. Typically homes in the south need more intensive crawl space work due to the high amount of humidity present in that region, driving up costs.

Size of Home

Crawl Space Condition

The condition of your crawl space determines what solutions your crawl space needs. For example, if your crawl space has standing water or floods frequently then a professional will have to install a crawl space sump pump or if your crawl space access door or portal needs replacement then a new access point must be installed, increasing your crawl space encapsulation cost.

With over 50% of the air you breathe coming from your crawl space you want to make sure that you are breathing the best quality of air (benefits) possible. Choosing to install poor quality crawl space encapsulation components, such as 6 mil vapor barrier liners have detrimental results. It’s also important to understand crawl space encapsulation is not a DIY weekend project.
