Job Stories From King County, WA
Waterproofing Crawl Space in Redmond, WA

Bill and Ruth of Redmond, WA, first initiated contact with our office due to water getting into their crawl space. There was water on top of the existing vapor barrier, indicating insufficient drainage and wanted to find a way to keep the space dry all the time. We came to the rescue and installed new crawl space drainage to lead water to our SuperSump sump pump system. The piers, walls, and floors were completely sealed with our CleanSpace encapsulation system, a heavy-duty vapor barrier that completely protects the crawl space from intrusion. All of the vents were closed-off, and we put in a SaniDry dehumidifier to maintain proper humidity below 55%. The result was a completely dry, healthy environment for years to come.

Crawl Space Moisture Barrier in Bothell, WA
Lisa and Todd were planning to sell their home in Bothell. During a pre inspection, they found out the vapor barrier in the crawl space needed replacing. They contacted Rainy Day for a free estimate.
 
Design Specialist, Ryan Adams, proposed we first clean out their crawl space. Then, he recommended installing a 6 Mil black poly vapor barrier. Next, we would fill their Positive Drain with concrete to prevent future water from coming in. Once complete, this project will help bring the home up to speed and ready for sale.

Water in Bothell, WA Crawl Space

Royce's crawl space started having water seepage, which made its way into his basement with about an inch of standing water during the recent heavy rain. He and his family never wanted to have to deal with flooding again, so we designed a solution ensure it stays dry. We installed crawl space drainage to collect water from the perimeter of the area. We installed our TripleSafe sump pump at the low spot to handle high volumes of water with ease. The space was encapsulated using 1012 square feet of CleanSpace, our 7-layer vapor barrier. The system will address the major problem areas to ensure no more damage is done and the home is protected.

Musty Smells in Bothell, WA Crawl Space

Liviu from Bothell was dealing with a bad odor in their crawl space. They were unsure of what was going on under the home, so they requested our help. The crawl space had lots of moisture above the vapor barrier and an overloaded sump pump. We installed our crawl space drainage channel along the inside perimeter at the wall/floor joint. We connected that to a newly installed SuperSump Plus sump system to better handle the volume of water coming in. Now, the home is dry and protected.

It was the first time had experienced a leak of this caliber after heavy rain. Design Specialist, Ed, came out for a free inspection and estimate, and discovered water was seeping through foundation at the wall/floor joint. 

 

Our crew installed WaterGuard Interior Basement Drainage, and our CleanSpace Wall System along two walls.

Crawl Space Vapor Barrier Duvall, WA

Alex and Jessica's home in Duvall, WA, needed a new vapor barrier installed. After hearing about encapsulation, they were interested in learning more. They called Rainy Day Basement Systems, and Nathan visited the home for a free estimate. The couple had the short-term goal of preventing rodents in the crawl space, but ultimately wanted to improve energy-efficiency, air quality, and comfort. They had problems with allergies, which can often be tied back to an unhealthy or moldy crawl space. We encapsulated their crawl space using our CleanSpace Vapor Barrier, and installed our TerraBlock and Foamax InsulationTo keep humidity low and prevent mold, we installed a high-performance dehumidifier and air filtration system, our SaniDry Sedona. Alex and Jessica now have a dry, healthy, and energy-efficient home, with clean air throughout.

Crawl Space Encapsulation in Shoreline, WA

Laura from Shoreline, WA, called us about her crawl space. She was looking to improve the home, and interested in encapsulation. Our expert, Ryan, came out to the home to provide a no-obligation inspection and estimate for free. He assessed the crawl space and found presence of rodents and dampness. He designed a system that would fix her home and improve improve it permanently using our CleanSpace Encapsulation System. CleanSpace is a fully-sealed vapor barrier that is attached to accessible dirt walls and floors to help isolate the home from the damp ground. It helps with blocking out mold, moisture, pests, and odors. In addition, sealing the space can help with ensuring comfortable floor temperatures, energy-efficiency, and air quality in the living space. 

Basement Waterproofing Woodinville, WA

Homeowners, Carol and Dan, called Rainy Day because they were having moisture problems with their home in Woodinville, WA. Water was leaking slowly through their foundation on one wall. We sent out Ryan to provide a free inspection, no-obligation estimate. The problems were ongoing for the past four to five years, and their biggest concern was mold and refinishing. To solve their wet basement troubles, we recommended installing WaterGuard Interior Basement Drainage. WaterGuard is a patented drain system designed to capture leaks along the stem wall. Water is then pumped out of the home through a TripleSafe Sump Pump, and discharged out toward a backfill area. The result is a dry basement, with groundwater seepage under control.
