The Crawlspace Extreme Makeover

The most common vapor retarder installed in homes today is a 4 or 6 mil polyethylene loosely spread on the ground which gets torn, moved around, and deteriorates over time . However, we offer a top of the line choice: a 15-mil multi-layer, prime, virgin, polyolefin liner with sealed seams that line the crawlspace floor and walls.


  • The wall liner completely seals the crawlspace floor and walls. It is mechanically fastened to the walls and piers to a level above grade but below the wood subfloor to prevent any water or vapor intrusion
  • The seams are overlapped and sealed with a special waterproof adhesive
  • The membrane has a water vapor permeance rating of 0.036 perms according to ASTM E 96 and ASTM F 1249
  • The life expectancy rating by ASTM E 154 is indefinite
  • The membrane has a tensile strength of 54.4 lbf./in. and a puncture resistance of 2340 grams
  • It costs about half the price of competing Crawlspace Encapsulation products


  • The Crawlspace Extreme Makeover installation does the best job of sealing out humidity and contamination from the crawlspace and potentially entering your home
  • It will not get torn up in normal use
  • It will last a very long time
  • It increases the value of your home
  • Your crawlspace in converted into a semi-interior room
  • This material controls soil gases like radon and methane, soil poisons, and sulfates
  • This liner is incredibly durable

The Crawlspace Extreme Makeover Liner is for the discriminating customer who wants a long-term solution to their crawlspace but who also appreciates spending half as much as the competing product.

The cost for this service ranges from $2.00 to $2.50 per square foot of the crawlspace footprint.
