Radon Testing & Radon Mitigation in Mount Vernon

Responsible for more than 21,000 lung cancer deaths in the United States each year, radon is the second leading cause of lung cancer. Unfortunately, radon gas is hard to detect because it is odorless and invisible — making it incredibly dangerous. The best way to know if your home has high levels of radon is to have it tested by a qualified professional.

John's Waterproofing is your Mount Vernon radon testing and mitigation expert. Our highly-trained team can identify if your home has radon levels above the EPA-recommended 4.0 picocuries per liter (pCI/L). If necessary, we can help you reduce radon levels with a high-quality radon mitigation system.

Job Stories From Mount Vernon, WA

High Humidity Ruins Your Homes Health - Mount Vernon, WA

Having high humidity levels in your crawl space can have very negative effects on your homes health. It can lead to rotting wood, mold growth, and can even cause energy loss. This homeowner noticed a strange smell and found water in their crawl space. They researched water in the crawl space and found John's Waterproofing. Upon inspection, we found this home was experiencing those negative effects already with rotten wooden beams and mold growing. A full encapsulation would be necessary to regulate the humidity and adequately control the waterflow.

The starting point of a full encapsulation involves removing the falling fiberglass insulation and applying a spot treatment for the mold growth using Moldx. This is important to ensure we're starting with a fresh space for the drainage system and insulation to be installed. Our drainage system involves installing a perforated pipe along the interior perimeter that can safely transport water to the TripleSafe sump pump. From there, the sump pump can control water from flooding and safely push it away from the homes foundation. Then, TerraBlock is installed along with a CleanSpace vapor barrier. These are both cut to perfectly fit the crawl space and protect against moisture damage. The vapor barrier is installed between the concrete footing and the wooden posts to isolate and protect the posts. Lastly, SliverGlo is applied along the foundation walls to complete the insulation process and air seal. After this encapsulation is completed and the environment is controlled, the homeowner can now enjoy a safe and dry home.

Crawl Space in need of Repairs - Mount Vernon, WA

This tall crawl space was in need of help. The homeowner had noticed a damp odor seeping into their home, and upon inspection they found fiberglass insulation water logged and drooping with puddles of water and mud over the old vapor barrier. They called up John's Waterproofing to learn about what options would fit in their budget, landing on our PPP; pipe, pump, and plastic.

To begin we cleaned out the space. We removed the water logged fiberglass, the vapor barrier, and debris that was present. Following this we installed a three inch perforated pipe in a silt sock that wraps around the interior perimeter of the space. This collects groundwater which flows into the newly installed SuperSump Plus which pumps the water safely away from the home to a LawnScape outlet. We then installed a new 6 Mil vapor barrier, overlapping the edges and running it up the walls. This homes crawl space is now better prepared, the drainage and pump system will keep the space from dealing with any stagnant water. The 6 Mil will need to be replaced or upgraded in a few years, but the damp odor is gone since the water is successfully being directed away from the home.

Partially Finished Basement has had Ongoing Water Issues - Mount Vernon, WA

Having added space under your feet can be a great thing to have, unless it is plagued with water issues. This basement had a waterproof paint over the floor, which was cracked and bubbling from water pushing up from under the home. The walls had been finished with drywall, but these had signs of mold beginning along the floor. The homeowners were worried about loosing this space since it was used for storage, laundry, as well as a small workshop space. So they called up John's Waterproofing to receive their free inspection. Afterwards we sat down with the homeowner and talked over options, finding a solution to fit the home.

The first step was removing the old drywall. We then used a jackhammer to create a trench around the interior perimeter of the home. Within this we laid in a bed of gravel and our WaterGuard drain system. We also added one sixteen foot leech line that went along a bubbling crack along the floor to collect groundwater here and ensure it has a route to the lowest point of the space. In this spot we installed a TripleSafe sump pump that pumps the water safely away from the homes foundation to a LawnScape outlet. For the unfinished walls in the basement, we installed our CleanSpace Wall system and in the finished spaces we installed our ThermalDry radiant vapor barrier which acts as a thermal break while also providing waterproofing, guiding any moisture safely down the walls to the drain system. The ThermalDry radiant vapor barrier will be re-finished over. We then installed a SaniDry dehumidifier to keep the moisture in the air controlled. This space is now dry and healthy and the homeowners can enjoy the peace of mind knowing their home is protected.
