This Crawlspace had a vapor Barrier laid out, but not sealed fully. After years of water creeping into the space, it was a muddy mess with the insulation falling down. We did a full encapsulation and the crawlspace is ready to be dry and healthy from now on!

Basement Remodeling in Seal Rock, OR

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home.

  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

Job Stories From Seal Rock, OR
Crawlspace Flooded and Dirty - Seal Rock, OR

This homeowner had a plumbing leak in his crawlspace and the plumber discovered that water had been flooding the crawlspace over the years causing damage to the foundation of the home, for a waterproofing solution, the homeowner was sent to John's Waterproofing. 


Our System Designer arrived at the home and was greeted by the homeowner and went right to work; measuring the home and inspecting the exterior for possible contributing factors that could be causing or adding to the problem. Afterward, he sat with the homeowner to share his findings and presented a solution to suit the homeowner's budget while addressing the major issues that were found.


Our experienced crew came to do the work. First, all the old barrier and debris was removed from the crawlspace and a perforated pipe drain system was installed around the perimeter of the inside of the crawlspace and graded to push the water to the SmartSump that was installed at the lowest point. The discharge line was attached to the downspout pipe after making sure it was flowing satisfactorily.  Next, a new 6mil plastic barrier was installed on the floor, covering all the dirt and overlapping 18" and fastened up the side of the foundation to ensure that any water intrusion from the wall or footing would find its way to the drain system. The homeowner was impressed with the professional and hard-working crew and loved the 10 yr warranty! 

Reclaiming A Homes Clean Air -Seal Rock, OR

This homeowner found John's Waterproofing booth at a Home and Garden Show and was fascinated by what she learned about the company and CleanSpace. As she and her children suffered from allergies, she was very intrigued and wanted someone out as soon as possible.


Our System Designer was dispatched a few days later and did a thorough examination of the crawlspace and exterior of the home.  They sat down and put together a plan for remedying the water issue with a complete cleanout of the crawlspace, including all debris and the old insulation. Once completed the exterior vents were sealed and a perimeter drain system was installed to gather and lead the water to a SuperSump and an UltraSump Battery back up to ensure continued operation in the event of a power outage. Next, the floor was covered with TerraBlock, a high-density foam barrier that aids with insulation and protects the CleanSpace barrier. The posts are all isolated from the moisture and the CleanSpace 20mil, nylon-reinforced plastic barrier, was laid out. All seams were sealed and the barrier was run up and attached to the foundation walls. A SaniDry dehumidifier was installed to ensure that the space stayed dry, thus killing all existing mold and preventing any regrowth as the air was continuously cleaned. With over 50% of the air in your homecoming from the crawlspace, keeping it dry and healthy protects your home and family. 


The homeowner reported that their breathing improved greatly in a very short time.

Wet Crawlspace in Seal Rock, Oregon

This homeowner called fearful of water in their crawlspace. Our inspector Daniel came out and confirmed they did indeed have water in their crawlspace and it was beginning to make some of their foundation posts damp and soft, which over time will rot the post through and can create an environment where mold can grow. 

The homeowners listed to all of Daniel's suggestions and chose to do the full crawlspace encapsulation. This included removing the damp insulation, installing a perimeter drain system and sump pump and then encapsulating the whole space with our patented CleanSpace System and installing the SaniDry Dehumidifier. This allows for the home to be dry and comfortable. 

As a final finish, the homeowner opted to add perimeter spray foam insulation. This will reduce the home's energy use by up to 30% a year!
