Job Stories From Sisters, OR
New Construction Presenting Water Problems - Sisters, OR

The homeowner was nearly finished with this beautiful home in Sisters, when they discovered a large amount of water in the crawlspace after a rainstorm. This was not something that was expected, so John's Waterproofing was called up for help. A System Designer traveled over the mountain to check out the situation. The homeowner was pumping out the water when he arrived so he was able to go into the crawlspace to inspect. He could see by the water line on the foundation that the crawlspace had roughly 8 inches of water at the peak of the flooding. He measured the space and sat with the homeowner and put together a proposal on his computer that would take care of the problem. The homeowner didn't want this new home to be compromised so they chose to move forward with a full encapsulation solution. 

The crew arrived a few weeks later to do the work. They had very little debris to remove from the crawlspace and then they got to work digging a trench around the perimeter of the crawlspace to hold a 3" perforated pipe encased in a silt sock to gather the water. This system terminates at the lowest spot of the crawlspace to a new TripleSafe sump system. The sump discharged the water to a 60' line of drain pipe that was installed underground down the slope of the property, terminating at a LawnScape outlet so the water could safely run downhill. Next the crew laid down TerraBlock insulation over the dirt floor. We then brought in CleanSpace. This 20 Mil woven vapor barrier is inserted under each wooden post, anchored along the walls, and fully sealed into place. The vents were then sealed up, and a SaniDry dehumidifier is installed to control the moisture, preventing mold from being able to form. A few days later our spray foam specialist arrived to apply spray foam along the foundation walls to make this space fully insulated and lower the homes energy bills. 

Crawlspace in Need of Help - Sisters, OR

This homeowner suspected that some cleanup and repairs might be needed for her crawlspace so one of our Design Specialists was scheduled to go take a look. Once there, he thoroughly examined the crawlspace and shared his findings with the homeowner. After sitting with her and sharing the options, the homeowner chose a full crawlspace encapsulation for its advantages in health and more, so the job was scheduled.

Our crew removed the 6 mil vapor barrier, drooping fiberglass insulation, and debris. They installed a 3" perforated pipe drainage system around the perimeter to collect the water and direct it to a newly installed TripleSafe sump pump, along with proper discharge. TerraBlock, a high-density foam product was laid over the dirt floor. This aids in insulating the crawlspace protecting the new CleanSpace, 20mil, nylon-reinforced barrier. This is also used to isolate each wooden post from any moisture and all seams were sealed up and anchored to the foundation walls. Lastly, a SaniDry dehumidifier was installed to ensure this home stayed dry and healthy. With all the vents sealed, Spray Foam insulation was applied to the full wall of the foundation to keep the home insulated and keep the air clean and free of mold.

Falling Insulation Clogging Crawlspace in Sisters, OR

This home had significant amounts of water that had soaked up into the fiberglass insulation. Each year when the snow and ice melted, this crawlspace would take on a lot of water. With the melt-off coming down the hill, it led to high water levels which soaked up into the insulation, leading to this falling down in pieces. Due to the falling fiberglass, this crawlspace was difficult to maneuver through.

To begin we removed the old fiberglass insulation and debris from under this home. Then a 3" perf-pipe drain system was done around the perimeter and graded to a new Sump system. Then Terra Block was laid throughout and all posts were isolated with our 20 mil vapor barrier the barrier was laid out in the crawlspace and sealed with special 4" tape at all seams; SilverGlo was installed along the walls with spray foam to air seal the space. As another layer of protection, a SaniDry Sedona dehumidifier was installed to truly keep this home dry and healthy. 

Energy Costs Sore Due to Crawlspace in Sisters, OR

This home had experienced very high heating costs during the Winter season. Looking to save money, they turned to their crawlspace to look for a solution. 

Our crew came out and began by cleaning out the crawlspace. Our TerraBlock crawlspace insulation was laid out on the floor to help maintain a warmer temperature. The crawlspace walls were then covered with our SilverGlo panels. Each post was then isolated with our CleanSpace vapor barrier which encased the entire crawlspace flooring and against the walls. New vent covers were then added in and a SaniDry Sedona dehumidifier. The homeowners quickly saw their energy bills lower, and their home was more comfortable year-round. 

New Homeowner Discovers Sagging Floor under Carpet - Sisters, OR

The Homeowners just purchased their home and wanted to redo some of the interior before moving in. The removed the old wood stove, and ripped up all the old carpeting, and that was when they discovered that the floor was sagging, especially in the spot where the old stove had been. The crawlspace never had additional support put in to be able to handle the weight. Over the years the moisture had seeped into the floorboards and the weight of the wood stove escalated the issue. With the carpet, this was difficult to see, but with the space bare, it was blatantly obvious. 

To protect this house we started by going in and removing all the old debris. Our experts then added in SmartJacks to the sagging floors so that the homeowners wouldn't have to worry about the homes floors giving out. We then added in a new 20 Mil Plastic Vapor Barrier that is tear resistant and sealed it along the interior of the crawlspace, securely inserting it under each post so no water or moisture could creep into the woodwork. 

No More Water Intrusion for a Crawlspace in Sisters, OR

After receiving a call from a homeowner in Sisters, Oregon about a wet crawlspace, our crews went to help fix the problem. Our team removed debris from the crawlspace and then installed Terra Block underneath the CleanSpace encapsulation system to add extra insulation and padding. CleanSpace will not only keep out water vapors from entering the crawlspace but also help keep the heating costs down by keeping the floors warmer. A SaniDry dehumidifier was also put in the crawlspace to dry and filter the air, getting rid of damp or musty odors that may travel into the rest of the house. The customer and our team agreed that a SmartDrain plumbing leak system would be important to have in the crawlspace as well. Never again will the homeowner have to worry about plumbing leaks going unnoticed and possibly causing serious damage to their home. Th SmartDrain system not only alerts the homeowner of a leak but also drains away the water until the leak can be fixed. The customer can now rest easy about their dry crawlspace and overall health of their home.
