    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.

    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 noticing a musty smell throughout their home, and felt like their home was having issues retaining heat in the winter, and cold air in the summer. They went to check their crawl space and found that there was standing water, and most of their fiberglass insulation was falling from the ceiling of their crawl space. They called John's Waterproofing to get a free inspection and estimate. After our system design specialist was done with the inspection, he met with the homeowner and after discussing solutions, they decided that a crawl space encapsulation was the way to go. To begin this project, our team goes in and removes all the debris like the fallen fiberglass and damaged vapor barrier. Next, our team digs a trench around the interior perimeter of the crawl space to then lay down a perforated pipe into a silt sock. This will secure a safe passage for the water to drain to the SuperSump pump at the lowest point. Our SmartDrain system is also installed, this backup system will alert the homeowner of a possible plumbing leak with an audible alarm and drains away the water into a drywell under the CleanSpace until the homeowner is able to get it fixed. Our team then installs our TerraBlock directly on the dirt floor of the crawl space. This acts as an insulated barrier between the home and the earth that will keep moisture from making its way up through the crawl space floor.  Next our team installs CleanSpace, which is placed on top of the TerraBlock system, on the foundation walls and up to the rim joists. All the vents in the crawl space are sealed to prevent outside air from getting in. Our team then installs our SaniDry Sedona dehumidifier which will control the environment and pull out any moisture. This will promote clean healthy air through the entire home by eliminating damp musty odors by drying and filtering the air. To finish this encapsulation our team sprays our foam insulation along the foundation walls, up to the rim joists. This homeowner can now be sure that their energy costs will lower and the air they're breathing is healthy and clean. A protected crawl space not only benefits the health of the homeowner but the longevity and health of the entire home for years to come.
