Does crawl space encapsulation increase home value?
Whether you’re looking at crawl space encapsulation because you have standing water under your home, have heard how it can reduce heating and cooling costs, or are concerned about negative effects of poor air quality, encapsulating your crawl space will definitely increase your home’s value.

A crawl space vapor barrier costs $0.15 to $0.50 per square foot on average, depending on the thickness of the plastic, which ranges from 6 to 20 millimeters. An average vapor barrier installation costs $2 to $4 per square foot or between $1,200 and $4,000 for materials and labor.
How long does crawl space encapsulation last?
Generally speaking, most companies will offer a warranty of between 15 and 20 years for a typical crawlspace encapsulation project. However, if the humidity levels are controlled and no catastrophic events such as flooding occur, a properly encapsulated crawlspace can last for more than 20 years.
How do you seal a dirty crawl space floor?

You should encapsulate state and implementation details so that object has full control on that. Logic will be focused inside object and will not be spread all over the codebase. And yes – encapsulation is still essential in programming as the code will be more maintainable.
Does crawl space encapsulation stop radon?
Radon moves up through the soil and into the crawl space air. Crawl space encapsulation can reduce radon levels and prevent moisture damage.. Radon is an invisible, odorless radioactive gas that comes from the decay of uranium in the soil.
What is the difference between a vapor barrier and encapsulation?
The difference between a vapor barrier and encapsulation in a crawl space is thickness, flexibility, and a sealed interior. Because vapor barriers are not sealed systems, moisture can bypass the vapor barrier and get into the crawl space. As such, it’s not a perfect solution to water evaporation under your home.
How much value does encapsulation add?
Crawl space encapsulation helps to stabilize temperatures in the crawl space — and ultimately, throughout the rest of your home. This reduces stress on heating and cooling equipment and can lower energy costs by an estimated 10% to 20%.
