Lynnwood Crawl Space Encapsulation

Lynnwood Crawl Space Encapsulation

Lynnwood Crawl Space Encapsulation Lynnwood Crawl Space Encapsulation

This Lynnwood home had a messy crawl space. There was fallen insulation, evidence of rodents and it leaked during heavy rains. Rainy Day cleaned out their entire crawl space, including the ruined insulation, and added drainage trenching and a TripleSafe Sump Pump to control water seepage. We then encapsulated the space with CleanSpace. Once sealed, we added a SaniDry CX Dehumidifier to further control the moisture.

David and Linda, from Lynnwood, WA, were having moisture and mold problems in their messy crawlspace. They wanted to improve the conditions of the environment under their home before selling it. We visited them for a free inspection and estimate to determine a solution that met their needs.


Our crew installed our SmartDrain System. This crawl space drain which can channel out water beneath the vapor barrier and prevent it from collecting in the space. We also installed our CleanSpace vapor barrier. CleanSpace seals the crawl space from the damp soils underneath. Finally, we installed the SaniDry Sedona dehumidifier. This is very important to keep humidity low in the crawlspace.


The result was not only a cleaner crawl space but also far less musty air in the home. Plus, no more critters such as carpenter ants entering through crawlspace openings. David and Linda started noticing positive changes in their air quality right away after having the work completed.

Job Stories From Lynnwood, WA
Repairing Wet Crawl Space in Lynnwood, WA

Twenty years ago, Won purchased his home in Lynnwood, WA. What he did not realize was that eventually, his humble abode would become riddled with a rotten and moldy smell, and it was coming from below in his crawl space. In winter, he was inconvenienced by standing water in leaking into the crawl space. This contributed to steadily increasing allergy symptoms and rotting support posts. Our production crew came to the home and installed new drainage trenches to lay piping to allow water to flow to the low spot of the crawl space toward the sump location. We installed our TripleSafe sump pump system to empty out a discharge line and out away from the yard from the LawnScape Outlet. To prevent moisture from entering and growing mold, we encapsulated the crawl space using our CleanSpace vapor barrier. The project lasted only a few days but made a huge impact on the health of the home.

Wall Cracks and Sagging Floors Restored in Lynnwood, WA

Jenny & Simon had been living in Lynnwood, WA for several years when they started noticing doors sticking, floors sagging, and walls cracking throughout their home. With recent heavy rains, they saw their problems worsening by the day. The water main on the street was broken, forcing water to divert under their home. They were afraid that the foundation might be settling and wanted to find a permanent solution for their drywall cracks and sloping floors.

Our recommendation was a new drainage system that would lead the water away and prevent further damage from happening. In addition, our SmartJacks system would lift the foundation back into place and solve the sagging floor issue. With these changes, Jenny & Simon will be able to enjoy their home with no further damage.

If you are experiencing similar symptoms, these could indicate settling or moisture issues. We offer free inspection and estimates to fix these problems for good, call today to schedule an appointment with one of our inspectors at 360-435-6992

Wall Cracks and Sagging Floors Restored in Lynnwood, WA - Photo 1
Finishing Flooded Basement in Lynnwood Home

Dave and Kelly S. had lived in their Oak Harbor home for 21 years. In the more recent ones, their East basement wall had started to leak water, especially during heavy rains. They had seen up to two inches of water in their basement at one time. Because of the frequent water, the carpeting had been damaged badly and was eventually removed. Dave and Kelly planned on moving at some point in their future and knew that the damages would bring down the value of their home. By making the investment in a Rainy Day Basement System, not only did they increase the value of their home, but their quality of life as long as they remain there.

To prevent water from reaching the basement walls, Rainy Day installed our WaterGuard drainage system. This piping system was specially designed to prevent clogging by separating it from the soil underneath the floor. Seepage is also prevented by installing our crawl space encapsulation lining, CleanSpace. By completely isolating the space from the earth below, the antimicrobial lining is highly effective at lowing the amount of moisture in the crawl space, and in turn, lowering the possibility of mold and mildew growth.

All captured water is pumped through their newly installed SuperSump pump, equipped with a cast iron pump, airtight lid and WaterWatch Alarm System. The alarm system alerts the homeowner if water rises above the point where the pump should be on, allowing them to intervene before serious damages occur. The water is then pumped out through their LawnScape outlet, a buried discharge line that safely carries the water a safe distance away from the home.
