    Boss came and went over all the options that we had picked. We kept changing our mind. I told them one thing and my husband told them a different thing. He got us all together on the same day with the salesman so that we could pick out what we really wanted to get the finish the way really wanted.That was really helpful.

    Crawl Space Encapsulation and Drainage in Arlington, WA

    When they purchased their home in Arlington, this homeowner knew the crawl space needed a complete overhaul. It had an old vapor barrier with moisture on top, rodents, and bad insulation. To create a healthy and protected space under the home, we sent Jean-Paul Holcomb to design a proposal. He developed a system to address the moisture, mold, and rodents. Our long-term solution comes with a guarantee and will help save energy in the process. Check out the full photo gallery for this project here.

    Installing Crawlspace Drain and Vapor Barrier in Lake Stevens, WA

    Pam and Steve B. had a damp and pet-friendly crawlspace in their Lake Stevens, WA, home. Jean-Paul Holcomb designed a solution to fit their needs and eliminate their problem for the long haul. Foreman, David Nush, and the crew added in a new SmartDrain to protect the crawl space from potential plumbing leaks above the vapor barrier. Then, we wrapped and sealed the piers, walls, and floors in our highly-durable CleanSpace encapsulation system. CleanSpace blocks the entrance of rodents and moisture while creating a dry, mold-free environment. Finally, to filter the air and maintain humidity, an energy-efficient SaniDry Sedona dehumidifier was installed. By encapsulating their crawlspace using CleanSpace and our SaniDry, the couple is increasing their home's value and comfort. They are also protecting the home while saving money on energy costs with their new system.

    A senior living facility in Edmonds, WA, was having trouble with a leaky crawl space and basement and the water was coming up from the foundation. The owners of the property needed a permanent fix, so we sent System Design Specialist, Jean-Paul Holcomb, to provide a free on-site inspection and estimate. Once he was able to determine the solution to control the water leaking in, we had our crew with Foreman, David Nush, out to complete the project over the span of a week.

    By installing an interior drainage channel in the basement, we were able to re-direct water from the ground to a brand new TripleSafe Sump Pump System. With the TripleSafe, the property owners have peace of mind. The three-in-one pump system can handle thousands of gallons of water per hour and even keeps working when the power goes out with a battery back-up.

    Health and indoor air quality were very important to Peter & Karla from Mount Vernon. Their new home's crawl space had rodents, mold, and standing water. Karla was also dealing with respiratory issues. Jean-Paul designed a system to fix their crawl space for good using our CleanSpace Encapsulation System. CleanSpace isolates the home from the earth's moisture to create a controlled, safe environment.

    Water, Mold and Spiders Invading Mount Vernon Crawl Space

    The odors from their crawl space were giving David and Bonny R. headaches and making them feel ill. They reached out to Rainy Day, looking for a solution to their broken sump pump and leaking crawl space, as well as the problems that ensued such as water damage, mold, mildew, wood rot, rust, poor insulation and insect infestation.

    Mold and mildew love wet, warm and damp environments, making the before crawl space a hospitable home. The 13 wide-open vents around the crawl space allowed water and dirt in, providing a foundation for the mold and mildew to start, grow and spread.

    Bugs and other pests such as spiders like rotting materials like wood. As seen in the before picture, a large spider is making himself a cozy home next to the mold on the ceiling. There were spiders and eggs all over the crawl space, making matters worse.

    After cleaning out all the muck—rotting wood pieces, rocks, mold, webs, the old plastic liner—we leveled the uneven surfaces. Then, to solve the leaking, mold and odor issues, we installed a full drainage and encapsulation system.

    As seen in the after picture, we placed SilverGlo and CleanSpace on the walls after removing the mold and debris from the ceiling and pipes. Both SilverGlo and CleanSpace are durable, providing insulation for the crawl space, keeping condensation off the walls and creating a barrier from outside air, dirt, and pests. CleanSpace and SilverGlo are also inorganic, so they will never mold or rot. The heavy-duty white CleanSpace liner is flexible, puncture resistant and creates a healthy and welcoming crawl space.

Once they learned their new home was drafty and wet from having a vented crawl space, they decided to have our CleanSpace system installed again. Now they can enjoy their home while saving on energy, increasing their property value, and protecting the home from mold and moisture.

    Fixing Mold in Damp Crawl Space, Bellingham, WA

    A mold sensitivity in the family led David and Isabel to contacting Rainy Day to their home in Bellingham, WA. We sent out System Design Specialist, Jean-Paul out for a free inspection and estimate to determine their solution to protecting the home from the mold in their crawl space.

    We sent Foreman, David Nush, and the crew out to install our CleanSpace encapsulation system. Conventional unvented crawl spaces are unhealthy and huge energy wasters. To prevent allergen and moisture intrusion, we put in CleanSpace, a durable 20mil thick vapor barrier. This can help seal out cold while reducing moisture and humidity favorable to mold, milew, wood rot, and pests. When we install CleanSpace, the edges and penetrations are all taped, caulked, and sealed. After installing the encapsulation system in the family's home, we installed our SaniDry Sedona dehumidifier. We recommend SaniDrys along with any CleanSpace encapsulation to get best performance from your system. This keep humidity low and also prevents any further allergen growth.

    Brian B. of Bellingham, WA, was ready to get his crawl space waterproofed because he was tired of uneven floors and dampness under his home. We installed a new drainage channel to guide water coming in safely through to our TripleSafe sump pump system. With three pumps in one, the TripleSafe can easily handle high volumes of water and is also equipped with a battery backup pump to keep the system running during power outages or pump failure. We protected the crawl space using a thick CleanSpace liner, which stops moisture from getting into the crawl space from the damp soil beneath. Finally, we put in a SaniDry Sedona Dehumidifier to filter out allergens and keep humidity at bay. The result was a clean, dry, and worry-free crawl space.
