    Insulation Issues Resolved with Spray Foam- Bend, OR

    Spray foam insulation is one of the best decisions a homeowner can make for their home. Not only does it help with keeping a home comfortable and dry, but it will help save money on energy bills. Spray foam is simply the most cost effective way to improve the homes energy efficiency. The install process allows the foam to be sprayed into every crack and void that is usually missed with traditional fiberglass insulation, increasing effectiveness and performance. These homeowners were noticing a rise in their energy bills and reached out to John's in hopes of helping lower costs and upgrading their crawl space. After our system design specialist went out to perform a free inspection, he met with the homeowners to go over options and they moved forward with the proposed repair plan. To start this project, we removed all the debris, old fiberglass insulation, and damaged vapor barrier. Due to the warmer atmosphere of the area, this home did not experience ground water issues, but more humidity issues that occurred during the warm summer, so the home did not need drainage. We install our TerraBlock system, which goes directly on the dirt floor to create an insulated barrier between the home and the earth. On top of the TerraBlock, we install our CleanSpace vapor barrier. This goes all along the foundation walls, up to the rim joist and is sealed with our waterproof tape at the footing of the wooden posts. In this process, we cover all of the vents to make sure no outside air enters. To control the environment, we then install our SaniDry Sedona. This effective dehumidifier will eliminate damp, musty odors by drying and filtering the air. It will also keep the environment at a healthy relative humidity. Lastly, we install our foam insulation. This is sprayed all along the foundation walls, up to the rim joists, ensuring a complete airtight seal. With this crawl space fully sealed and protected with our encapsulation, these homeowners will see their energy costs lower.

    Upgrading The Crawl Space - Yachats, OR

    This crawl space was causing a multitude of issues for this homeowner, such as uneven cold floors, water intrusion, and rodent activity. They wanted a permanent solution to these problems so they called John's Waterproofing. We had one of our system design specialists go out to give a free inspection and estimate. Once the design specialist was done, he met with the homeowner and they discussed the findings of the inspection and found that an encapsulation would be the best solution. An encapsulation is the process of sealing the home from the earth.  To start this project, our team goes in and removes all the debris. Our team then does a dig out to even the crawl space floor. After, our SmartJacks are installed, they are our high-capacity adjustable supplemental steel piers designed to stop settling and evenly raise the floor back up to where it was. The next step is to dig a trench around the interior perimeter of the crawl space to then lay down a 3 inch perforated pipe into a silt sock and this secures a safe passage to drain water to our TripleSafe sump pump at the lowest point. Our TerraBlock is then installed directly on the crawl space floor which creates an insulated barrier between the earth and the home. Then, our CleanSpace system is installed on top of the TerraBlock and up the foundation walls. All the vents in the crawlspace are sealed shut to prevent outside air from getting in. Our EverLast Door is also installed, which is an above grade door that will allow exterior access to the crawl space, and is reliable in all weather conditions. Next our EverLast Access Well is installed, it is big enough for someone to crouch down and enter the crawl space, and it is durable enough to hold back soil and will last for many years without rusting, rotting, or needing paint. Controlling the environment is next, our SaniDry Sedona dehumidifier is installed and this will help to pull out moisture and will filter and dry the air. The last step is to spray foam insulation in multiple layers, along the foundation walls, up to the rim joists and this will ensure an air tight seal to finish this encapsulation.

    This homes crawl space had the old fiberglass falling, and it smelled very musty. The owners of the home were concerned about the health risks that could be occurring by living with this kind of mess under their feet. To get assistance, they called up John's Waterproofing so they could learn about what they could do. This is how they learned about encapsulation. The owners were sold on this solution; energy savings, indoor air benefits, and overall health benefits for the homes longevity. We pulled out the old vapor barrier, fiberglass, and general debris. We then installed drainage, a sump pump, and insulated with TerraBlock and Spray Foam. We use a CleanSpace vapor barrier, and installed a SaniDry dehumidifier. Now this space is dry and healthy.

    This homeowner was concerned about humidity and a musty smell in their home and wanted to find a solution to this problem. They reached to John's and scheduled their free inspection. One of our knowledgeable system design specialist performed a thorough examination of the crawl space and then met with the homeowner to go over the best options to solve this issue permanently. When hearing how a full encapsulation offers improved air quality, reduced energy bills, and protection from water, pests and mold- they went ahead with the estimate and we began the project. First, we made sure to remove all of the debris, along with the fiberglass insulation, and damaged vapor barrier. Mold was found in some areas, so we use our Mold-X2 which our highly effective cleaner for contaminated surfaces. Mold stains are removed in 20 seconds. Next, we dig a trench around the interior perimeter of the crawl space to install a 3 inch perforated pipe into a silt sock. This creates a safe passage for water to collect at the lowest point. Then, at this point we install our SuperSump Plus. This will gather all of the water and pump it outside and away from the homes foundation via discharge line. We make sure to cover and seal all of the vents to prevent outside air from entering. On the dirt floor of the crawl space, we install our TerraBlock system which will create an insulated barrier between the home and the earth. This will also block out moisture from making its way up through the floor of the crawl space. On top of the TerraBlock, we install our CleanSpace system. It is also anchored into the foundation walls up to the rim joists and is sealed at the footing of the wooden posts with our waterproof tape. To keep the environment controlled, we then install our SaniDry Sedona Dehumidifier that will eliminate the damp and must odors by drying and filtering the air-as well as keep the home at a healthy relative humidity. Lastly we install our foam insulation onto the foundation walls, up to the rim joists. This type of insulation differs from traditional fiberglass because it is sprayed in layers and than it expands, filling every crack and void, ultimately providing a complete airtight seal. This full encapsulation will protect the home and create a dry, healthy and stable environment for years to come.
