Existing 12 mil vapor barrier was cut by ilvendor to install French drain several years ago... just bought the home and used this to seal up over the drain, and new barrier over existing floor. Difficult to use to wrap columns but great product

Ok, so it's a little hard to for sure say the product is 5 stars durable since it was just installed, but based on what it feels and looks like, I would say it seems that it is of high quality and durable. Used to encapsulate a small crawl space in a 1920s townhome.



Service and delivery was great...I ordered Friday and received it on Tuesday afternoon (in Ohio)! Convenience, price, and service were great...I looked online for a comparable product / price and found nothing. If I ever need to buy similar supplies, I would definitely be a return customer.

12 Mil Crawl Space Vapor Barrier, GuardianLiner™ - Great Product

Pros:
  • quality
  • easy to install
  • durable
Cons:
Had lived in a house for 14 years, and the so called vapor barrier in the crawl space was relatively thin clear plastic which was torn up near the entrance to the crawl space due to HVAC and pest control people crawling over it over the years. We were putting our house on the market and wanted a durable vapor barrier that would look good and do the job for years. On a budget, we didn't want to pay the $3000 to $4000 for someone else to install, so looked for other options. We ordered the 12 Mil Crawl Space Vapor Barrier with GuardianLiner™ from CrawlSpaceRepair and have been very pleased. It arrived earlier than expected, and, with proper planning and cutting into the appropriate pieces, was easy to install. The tape worked well for connecting the recommended overlaps, and the finished product looks great. Since the house has been under contract, several people have been in the crawlspace (contractors, HVAC technicians, etc.) inspecting or making minor repairs, and all have praised the quality of the vapor barrier. It looks fresh and clean, and is clearly an improvement over the prior material. I highly recommend the product, and if you have any do it yourself skills, recommend you do the job instead of contracting it out. We did not encapsulate our crawl space, but this material would be great for encapsulation also.

Super product! Used this in a small crawl space, DIY "passive wine cellar" - smells so fresh down there now. Far better situation that the very thin product used when the house was built. Thank you!

We love the quality and durability of the Guardian 12 Mil reinforced vapor barrier for crawl space applications. It is easy to install and gives us the results we expect.

I highly recommend this product used in conjunction with the 3" waterproof tape.
