Job Stories From Terrebonne, OR
Setting a Home Up for a Smooth Sale - Terrebonne, OR

As a home goes onto market, it has to pass inspections and meet local codes. This homes inspection showed water stains on the foundation walls in the crawlspace, and the old vapor barrier just wasn't cutting it. To ensure water is moving through the space and not sitting to cause rot or mold, the inspector recommended John's Waterproofing for our realty program. Here we provide a Pipe, Pump and Plastic to get this home dry and healthy. 

Our install crew arrived and pulled out the old vapor barrier and debris. Once the space was clean we dug a trench along the interior perimeter and installed a three inch perforated pipe in a silt sock. This will collect groundwater and grade it to the lowest point in the crawlspace where we installed a TripleSafe sump pump to discharge the water out and away from the home. We then laid down a new 6 Mil vapor barrier, overlapping the edges and running it up the walls. 

Wet Nasty Crawlspace - Terrebonne, OR

A new homeowner called John's Waterproofing after discovering that the crawlspace in their home had water ponding on top of the old vapor barrier. As indicated by its name, a vapor barrier is supposed to prevent moisture from invading the airspace so if water has breached the barrier, its use is null and void. A System Designer was sent to the home to do a full inspection, and help educate the homeowner on why it was happening and how we could solve the problem. 

When the installation crew arrived, they cleared the crawlspace of the old vapor barrier and the failing fiberglass insulation. A 3" perforated pipe drain system was installed around the perimeter of the crawlspace graded to a SuperSump pump with an UltraSump battery backup to assure that the system remained in operation in the event of a power outage. Then a new 6mil plastic vapor barrier was laid on the dirt floor, making sure that it was well overlapped and attached to the foundation wall so any water coming in via the footing and foundation was captured and directed into the system for removal.

Musty and Damp Crawlspace in Terrebonne, OR

This crawlspace was continuously wet, and while the homeowners had laid down a store bought 6 Mil vapor barrier, water would pool on top of the barrier and water mold was present. The crawlspace also had the old fiberglass insulation absorbing the water, so this was falling in strips to the dirt floor. The homeowners wanted to address this issue and called up John's Waterproofing for help. 

When we arrived we began by removing the damaged vapor barrier and the water logged insulation. Once the space was cleaned out we installed a perforated drainage system throughout the space. This collects the groundwater and grades it towards a newly installed TripleSafe sump pump. From here the water is pumped out and away from the homes foundation to a LawnScape outlet. We then laid down a new 6Mil vapor barrier, since this doesn't fully get sealed up like our CleanSpace woven barrier, we will come back in a few years to remove and replace as needed. 

Drooping Fiberglass and Mud Caked Crawlspace - Terrebonne, OR

We commonly have people call for a crawlspace 'clean-up'. They have a vapor barrier, but it is covered in dirt and mud. They have insulation, that is drooping and falling apart, they just want us to clean and reattach anything that is out of place. However, these are signs that the water issues in the crawlspace are not being properly addressed. The water levels are actually pooling over the top of the vapor barrier and the moisture content is inside of the insulation which leads to mold and mildew. When these homeowners called for a 'clean-up' we sent a design specialist out to inspect and evaluate their crawlspace. Afterward, we found a waterproofing solution that better suited the water their home was facing. 

We began with a clean-out. The old barrier was removed, and the old fiberglass insulation was all removed. With a clean surface, we dug down a perforated pipe system to collect groundwater and divert it to a new TripleSafe sump pump. This would direct all water out and away from the home with a new LawnScape outlet. We then installed SilverGlo crawlspace insulation on the walls to help with the home's energy consumption. Afterward, we laid down a new vapor barrier throughout the crawlspace to keep it dry and healthy! 

Crawlspace Insulation and Encapsulation - Terrabonne, OR

The homeowner discovered that the Crawlspace had received a lot of damage over the years of them living there. The Insulation that had been installed was flaking apart causing an expansive amount of insulation dust and clumps to be scattered throughout the area. Within the debris, droppings from vermin could be found and it was obvious that unwanted guests had been living there. 

Johns Waterproofing crew went in and removed all the debris, we then isolated all of the posts so no damage could seep into the homes wooden foundation. To make sure no water build up could occur, a Smart Drain and SaniDry Sedona dehumidifier was installed. We also added in Terra Block and Cleanspace sheeting throughout the space to encapsulate it. To finish off the job we added in spray foam to the ceiling of the crawlspace to replace all that had been destroyed and sealed the vents. 

The revamped crawlspace is now clean and easy to move through, no more musty odor or vermin signs. This closed off space is officially a CleanSpace!
