Job Stories From Culver, OR
Unhealthy Air in the Home - Culver, OR

A homeowner contacted John's Waterproofing because he was interested in encapsulating his crawlspace after learning about crawlspace healthy at a Home and Garden Show. With over fifty percent of your homes air coming from the crawlspace, the homeowner was curious if addressing this issue could help his allergies, particularly his allergy to mold. A System Designer went to the home and was able to confirm that there was mold growing on the floorboards of the home over the crawlspace. 

When the installation crew arrived, they went to work removing the old 6mil plastic barrier and the old, falling fiberglass insulation as well as other miscellaneous debris. Because there was no evidence of water issues, a perforated pipe drain system was not required for this project. The crew then laid TerraBlock, a flexible foam barrier on the dirt floor throughout the crawlspace. This aids in protecting the CleanSpace barrier and is a first step in insulating the crawlspace. The CleanSpace 20mil nylon-reinforced vapor barrier was laid over the insulation, slipped under the posts and seams were taped to seal off the crawlspace from any moisture from getting to any wood surfaces. It was run up the foundation walls and secured just under the rim joist. To complete the spaces insulation, we then applied single-cell spray foam to ensure the space in encapsulated. To ensure that mold can't grow in this space we also installed a SaniDry Sedona Dehumidifier and all the crawlspace vents were sealed. Keeping the humidity under 60deg and the air filtered is a crucial step in preventing mold from growing and establishing.  It also filters out dust mites and pollens to keep the air clean!

High Energy Bills - Culver, OR

This homeowner contacted John's Waterproofing because they were interested in encapsulating their crawlspace after visiting our booth at a home and garden show. 

Our System Designer showed up at the home and after introducing himself, he got to work measuring the home, inspecting the exterior, as well as checking the crawlspace for any signs that could be contributing to the problem. The specialist found that the old fiberglass insulation was falling in pieces, and water was pooling over the old and damaged vapor barrier. 

A few weeks later our experienced Installers arrived and began by removing all of the debris, old insulation, and the vapor barrier.  A perforated pipe drainage system was installed around the perimeter and graded to a newly installed TripleSafe Sump pump at the lowest point. To add in insulation that is catered to being in a crawlspace we installed TerraBlock on the dirt floor.  All the vents were then sealed and the wooden posts isolated. The 20mil nylon-reinforced barrier CleanSpace was laid throughout and all seams were sealed. It was run up the walls and fastened under the rim joist. A SaniDry dehumidifier was installed to ensure the humidity was controlled to prevent mold growth. Finally, a single cell spray foam was applied to the rim joist and foundation walls to bring the insulation to the required R factor for insulating the space. Now the homeowner had a clean and healthy home!

Dirty, Damp Crawlspace Transformation - Culver City

A homeowner called John's Waterproofing with concerns that mold in the crawlspace was affecting his family's health. We sent design specialist out to do an inspection. We did find signs of water and the resultant mold in the crawlspace so we recommended a CleanSpace encapsulation. 


The crew came out and removed the old, dirty barrier and fiberglass insulation and installed a perimeter perf pipe drainage system and graded it to the new TripleSafe sump and a discharge line was connected to the downspout drainage. TerraBlock, for both protection and insulation, was laid on the ground.  Next the 20 mil, nylon-reinforced  CleanSpace barrier was laid and fastened to the foundation walls just below the rim joist, and all seams were sealed with special, heavy-duty 4" CleanSpace tape, and each post was isolated to ensure that no water/moisture would get to the wood of the home. Lastly, on the exterior, all vents were sealed with specially designed vent covers and on the interior, a 2.5" layer of Spray Foam designed for encapsulation, was sprayed on the foundation walls and rim joist, and a SaniDry Sedona dehumidifier was installed. Now these homeowners enjoy a healthy home free of air contaminants.

Dual Crawlspace and Basement has Water - Culver, OR

This home had a small section of finished basement space which then connected to a crawlspace for the remaining foundation. The crawlspace had always had some water issues, but it seemed to stay in that space until the homeowners noticed their carpeting was damp and soggy. When they lifted up the carpeting near the crawlspace they found standing water, and part of their wall was damaged due to this. 

To solve the issue we started with the crawlspace, where we installed a SmartDrain and encased the space with our 20 Mil thick Cleanspace vapor barrier. We isolated the posts to protect them from water damage and anchored to walls. We then installed our SilverGlo insulation on the foundation walls to help regulate the energy consumption of the home. The crawlspace also got new vent covers. In the basement, we removed the carpeting and the damaged portions of the wall. We installed our WaterGuard drainage system around the interior perimeter of the room and sent all collected groundwater out and away from the home via a discharge line. We then installed our Everlast finished wall restoration system and our ThermalDry gray carpet squares to give this space a clean, dry and finished look. 

Crawlspace Water Build Up - Culver, OR

This house had experienced a large amount of water intake throughout the years. The homeowners had grown used to this and figured it was just how things went. After a musty and damp smell began to permeate their home, they decided there must be a better way. To eradicate the problem, they called John's Waterproofing. They had a large crawlspace with the dirt floor varying from two to four feet. The varying floor levels led to many sections with pooling water and places where debris would accumulate. 

The first issue to address in this project was to address the inconsistent floor levels. Our crew cleared out the debris and began to level the floor, grading it to a low point. Here we put in a SmartSump Sump Pump, specially created for crawlspaces. Then TerraBlock was laid and posts were isolated. We then isolated each post and covered the crawlspace with Cleanspace, a woven, and tear-resistant 20 Mil Vapor Barrier. This is fastened along all the concrete walls. Since the space also had high humidity, we added in a SaniDry Sedona dehumidifier to ensure no water vapor could creep into the home. 

The homeowners quickly noticed a change in the air quality and were amazed at how much fresher their home smelled. No more musty smells, and no more water intrusion. 

CleanSpace Encapsulation in Culver, Oregon

This homeowner called because they were concerned about the amount of water in their yard and the pooling around their foundation vents. They were sure that it was getting into the crawlspace. When our inspector Jacob went into the crawlspace, he confirmed the homeowner's suspicions. The water coming into through the vent was not the real problem though. This crawlspace has groundwater coming in from a corner of the foundation. The crawlspace had two inches of water across the vapor barrier and some areas where deeper pools had been created. Due to the water, the fiberglass insulation was falling and full of water. Jacob suggested our CleanSpace Encapsulation System. He also added an exterior French Drain in order to help prevent the groundwater from continuing to come into the space. The customer opted to have TerraBlock flooring installed as well as spray foam insulation on the walls. This insulated the space and will provide an average of 30% savings on their heating and cooling bills.
