Basement Before and Afters
  • Basement Waterproofed in Marysville WA
    Basement Waterproofed in Marysville WA

    This basement entrance shows the moisture penetration, efflorescence, and a large hole the home owners covered. After we are done waterproofing this Marysville basement, it will be dry and protected. This is thanks to our TripleSafe sump pump, WaterGuard drainage system with inspection ports, and CleanSpace wall system.

  • Efflorescence in Marysville Basement

    The efflorescence in this basement was a clear sign of moisture troubles. Water problems will no longer plague this Marysville, WA basement after the installation of our TripleSafe sump pump with our IceGuard discharge line system, WaterGuard drainage system, and CleanSpace wall system.

  • Marysville Home gets Restored with EverLast Wall Panels

    This Marysville beach home was allowing moisture into the basement through the walls, causing them to crumble from the interior. EverLast Wall Panels were installed to repair the crumbling walls in addition to preventing future water seepage.

  • New Insulated Walls Installed for this Bellingham Basement
    New Insulated Walls Installed for this Bellingham Basement

    Like many parts of Washington, Bellingham commonly gets long periods of rain. Homeowners, Martin and Genn, had water frequently leaking into their basement stairwell and they knew that the situation was just going to get worse.

    Their flooring and walls had water damage. Their basement, which was also their laundry room and storage area, was cold and unwelcoming. They did not want further damage to their home or items, so they contacted Rainy Day. After their free inspection and estimate, a plan was created to install a drainage system and restore the walls and flooring.

    In the before picture, we removed the old walls and saw that the concrete around the window was moist and moldy. The prior walls did not seal tightly, leading to leaking, moisture, and mold which then damaged the walls and flooring, and contributed to the flooding. Additionally, the weak seal meant that outside air was also coming in, resulting in letting cold air inside in the winter and hot air in the summer.

    The after picture shows the Total Basement Finishing EverLast panels (which are on top of Basement-to-Beautiful panels). All the panels fit snuggly around the pipes and windows, giving the room insulation in an attractive fashion. In addition, sandstone gray ThermalDry tiles on top of the cold concrete will help keep the temperature of the room under control whilst also making the room inviting. With this new snug seal on the inorganic walls and flooring, the homeowners don’t have to worry about mold, moisture, debris and air damaging their basement like before. They also won’t have to pay more to heat or cool a room that is not going to keep the desired temperature.

    Pump and drainage systems will ensure that any water that does come into the basement will be disposed of fast and effectively, even on really rainy days. The TripleSafe pump system with two pumps, a backup battery, and alarm system will provide the homeowners with the reassurance that their basement will be safe even in the wet Washington weather. WaterGuard at the perimeter of the basement and TrenchDrain in the doorways and stairways will collect and direct any water to the TripleSafe. The LawnScape Downspout will safely discard roof water far from the house foundation, helping keep water from entering the basement. IceGuards were installed outside the home to avoid flooding from pipe blockage due to ice, snow and other debris.

  • Sump Pump and Encapsulation in Freeland Crawlspace

    Barbara recently moved to Freeland and found standing water in her crawlspace. Rainy Day went to her home put in a TripleSafe. This is a top-tier sump pump system which for ensuring protection from flooding. The submersible design covers three major occurrences including pump failure, high water volume, and power failure, which means less worrying about keeping your basement or crawl space dry. We also installed our patented CleanSpace encapsulation system to be a super thick and durable vapor barrier that completely seals off the home from the earth.


Professional, Certified Waterproofers in Washington

Basement water problems are as old as the structures themselves. Water will leak into a basement through any opening it can, including your walls, floors, and the joints between them. Water can even pass through the concrete itself -- which is one reason why basements are notoriously damp, humid spaces.

Other companies might try to sell you on inferior basement waterproofing solutions. Our products have been developed, patented, and perfected by Basement Systems, Inc. -- the world's largest network of basement waterproofers. Whether you live in Everett, Marysville, Bothell, Edmonds, Lynwood, Mukilteo or Lake Stevens, our basement experts will show you how we can customize your waterproofing solution to keep the basement dry all the time!

Negative-side Sealant

This involves "painting" the basement walls and floors with a waterproof coating of cement that's meant to seal out the moisture.

It applies directly to the concrete's surface with a brush or roller and is often applied when a homeowner is preparing for basement finishing.

Exterior Excavation

This involves digging out the entire perimeter of the basement, installing a new drain, and possibly adding a waterproof coating on the walls.

This type of installation has been used for many decades—a drain of this type is generally installed when the home is built.

Interior Baseboard System

Installs on top of the basement floor with a drain that runs along the basement walls. Collects water and sends it to a sump pump system.

No jackhammering is required, and the installation is safe for a monolithic basement floor.

Interior Subfloor Drain

Installs underneath the basement floor, with a drain that runs along the basement walls. Collects water and sends it to a sump pump system.

The system is easy to service, and it can collect water leaking from the walls or windows as well.
