Foundation Repair in Portland, OR

The customer called needing foundation repair due to rotting beams under the home. Some of these beams were causing sagging areas in the floor. As he was researching beam replacement, he learned about Clean Space encapsulation. After reading all the benefits, he requested a quote for that as well. Our crew went out and installed our CleanSpace vapor barrier that is a 20 mil durable plastic and antimicrobial so he will never have to worry about mold or excess humidity in his crawlspace. He can also reap the benefits of more even heating and cooling in his home and a reduced energy bill. 

Before vs After: TerraBlock Insulation - Portland, OR

Insulation is an important step to keep moisture out of your crawl space and help with your homes energy efficiency. At John's Waterproofing we are able to completely seal the crawl space off from the earth and add moisture protection with TerraBlock insulation. TerraBlock is a 3/4 in. thick and puncture-resistant foam that insulates and helps control the environment in the crawl space. The earth is naturally always cool and applying the TerraBlock helps to keep the temperatures the same year round so that your homes heating/cooling systems don't have to work as hard to keep up with the changing climates, which leads to lower energy bills. It is made of materials that won't rot or grow mold which helps to keep moisture out. It is installed along the crawl space floor and is cut to perfectly fit into each individual space. We seal the TerraBlock in the crawl space with 4 in. thick waterproof tape and anchor it to the base. This ensures that groundwater can't rise up over top the insulation and evaporate into the air causing higher humidity levels. Overall, insulating the crawl space floor is an important step for our encapsulation system to keep your home dry and healthy.
