This homeowner had reached out to John's Waterproofing back in 2015 about getting their crawl space inspected. They noticed that during the rainy seasons water would seep inside the space and puddle. Because of this, the water would bring in dirt and debris from the outside and leave it behind on the vapor barrier as the water evaporated. We explained that a full encapsulation would prevent these water issues from continuing and they decided to wait and see if the issue resolved itself. Then, in 2025 the same homeowner reached back out saying that the water issues they were experiencing had only worsened and agreed to encapsulate the space. A full encapsulation is the process of sealing the crawl space off and controlling the environment to help prevent water intrusion, mold growth, and wood rot. It involves installing a drainage system with a TripleSafe sump pump, TerraBlock insulation foam, and a CleanSpace vapor barrier. Now, this beautiful crawl space is capable of keeping water out and the home healthy.
This homeowner was interested in having a whole home generator installed. They didn't want to have to worry about the inconvenience of a power outage or the costs that are associated with it. They loved how John's does the install from start to finish using the plumbing and electrical divisions, and were happy with how smooth the installation for the generator and the automatic transfer switch went.
The wooden posts in your crawl space are what support your home and keep your floors even. If water gets into your crawl space and get absorbed by the wooden posts, this eventually causes them to rot and grow mold. Once they have been water damaged, the damage could be irreparable and homeowners will have to spend expensive amounts to fix the structural integrity of the home. This homeowner experienced water in their crawl space and it began to deteriorate their wood by causing distortion and discoloration. They called John's Waterproofing about getting their crawl space encapsulated and protecting against future water damage. To begin the encapsulation, first we installed a drainage system using a perforated pipe and a TripleSafe sump pump. These work together to collect any water that tries to enter and offer a passageway to be pushed out of the crawl space and away from the homes foundation. We then install TerraBlock, a thick insulation foam, along the base of the space. Afterwards, a CleanSpace vapor barrier is installed on top of the TerraBlock, up the foundation walls, and between the concrete footing and wooden posts. We put the vapor barrier between the footing and posts to isolate and protect them against water from being able to seep up into the wood. Once the space is protected and sealed from the earth, then we apply Spray Foam along the foundation walls to insulate and air seal. A SaniDry dehumidifier is installed to help pull moisture out of the air. Once this encapsulation is fully completed, the crawl space is isolated and protected against moisture damage and the homeowners won't have to worry about the wooden posts supporting their home.
Water damage is every homeowners biggest nightmare. It can cause the wooden posts supporting your home to rot, increases exposure to mold growth, and structural damage can cost homeowners thousands. Good thing at John's Waterproofing our encapsulation process helps to keep your crawl spaces dry and healthy so that water can't cause any damage. The most important step in the encapsulation system is removing everything in the crawl space that has been water damaged. Usually that means we are taking out falling fiberglass insulation and the destroyed vapor barrier. Once everything is cleared out, we can install a proper drainage system. We dig a trench along the interior perimeter of the crawl space and lay a perforated pipe. This pipe can collect any water that tries to enter and offers it a safe passageway to a drain. For this encapsulation we installed a SmartDrain to collect the water from the pipe and send it away from the homes foundation. This system helps to keep the crawl space dry and avoid standing water. Afterwards, we install TerraBlock along the entire base of the space. This is a thick insulation foam that seals the earth from the house. It helps insulate and promotes energy efficiency because it regulates the environment. Next, a CleanSpace vapor barrier is installed on the base, up the foundation walls, and between the footing and wooden posts to isolate and protect. This vapor barrier differs from code regulated barriers because instead of only being 6 mil thin, it is 20 mil thick. It helps keep water from seeping over top and getting into the crawl space. A SaniDry dehumidifier is installed that filters the air by pulling out any particles or moisture. Lastly, Spray Foam is applied along the foundation walls to insulate and air seal the space. Once the encapsulation is completed, it has a clean look while also keeping it dry and healthy.
This homeowner was having issues with water in their crawl space, it was creating mold and mildew so they were wanting a solution fast, they called John's Waterproofing. After getting a free estimate and inspection, the system design specialist sat with the homeowner and went over the details of the findings and explained to the homeowner that the best solution to keep their crawl space dry and healthy was an encapsulation. To start this encapsulation we had our team remove all the debris from the crawl space. This crawl space had mold in some areas so we used our Mold X2 to spot treat it. Mold X2 is a highly effective cleaner for contaminated surfaces like wood. Once the mold is taken care of, the next step in this project is to install our drainage system. We start by digging a trench around the interior perimeter of the crawl space then we lay down a perforated pipe in a silt sock that will ensure water has a secure passage to the TripleSafe sump pump system that we installed. A discharge line is installed as well to pump the water outside. Next, our TerraBlock is installed directly on the dirt floor creating an insulated barrier between the earth and the crawl space. Our CleanSpace system is directly installed on top of the TerraBlock and up to the foundation walls and under the footing of the posts. All vents in the crawlspace are sealed shut.
Our SaniDry Sedona dehumidifier is installed to pull out moisture and keep this crawl space dry and at a relative humidity of 55% which will help prevent mold and mildew. To Finish this project, we spray foamed the foundation and this will ensure the space is air sealed and completely protected.
