Job Stories From Whatcom County, WA
Keeping Maple Falls Basements Dry with CleanSpace

Tony and Tina B. of Maple Falls first heard about Rainy Day Basement Systems through a local home show. However, it wasn’t until they were referred by A-1 Builders and Adaptions Design Studio that Tony and Tina sought out Rainy Day’s many services.

After encapsulating their basement with CleanSpace, an antimicrobial crawl space liner, a SaniDry CSB dehumidifier was added to keep the humidity low. Any water accumulated by the dehumidifier is pumped out through an added condensation pump to the exterior of the house. Any other water detected in the crawl space can be identified with the SmartDrain with Remote style Water Watch Alarm. This system can detect any plumbing complications that may be leaking into the crawl space. These types of leaks often go unnoticed as they simply absorb into the ground without a CleanSpace barrier.

Rainy Day is pleased that it was able to deliver the quality of products and services that Tony and Tina expected.

Ground Water Displacement Fix in Custer

Jeff and William called Rainy Day Basement systems when their front porch on their Custer home began to sink and they feared that it would bring their roof down along with it. Once Rainy Day assessed the situation, they determined that because of the all the water running under the porch to the crawl space was displacing the ground underneath the porch causing it to sink.

Rainy Day’s solution was to install SmartPipe Drainage Trenches throughout the crawl space leading all captured water to the lowest point, or where the sump pump is located. Thanks to its distinctive design, SmartPipe can collect water from foundation walls as well as from the dirt crawl space floor. They chose to go with a TripleSafe Sump Pump which comprises a cast iron primary AC pump, an airtight lid and floor drain and a WaterWatch alarm system to alert them of any plumbing leaks that should arise. The entire space was encapsulated in CleanSpace, an antimicrobial lining that completely isolated the space from the earth below. A SaniDry XP dehumidifier was installed to keep the space at a low humidity and a steady temperature. Finally, a LawnScape outlet was added to carry all unwanted water caught by the entire system a safe distance away from the home where it cannot displace the ground below it.

Ridding an Everson Home of Moisture and Mold

Lynne and Keith were having significant problems with their crawlspace. Moisture filled the air in the space, leaving all of the surfaces dingy and damp. This made the space nearly impossible to use and the smell from it was filling the air in their home.

Rainy Day Basement Systems encapsulated their entire crawl space, isolating the house completely from the ground below. The space was enclosed with CleanSpace, a 20 mil. thick antimicrobial liner that dramatically reduces the humidity level in the air. In combination with the SaniDry CX dehumidifier, the system leaves the humidity in the air low enough that mold can become dormant and end the unwanted odors Lynne and Keith were sensing.

They can now make substantial use of their crawl space and enjoy the fresh air coming out of it.

Getting a Blaine Home in Selling Condition

Connie and Rich had lived in their Blaine home for 25 years, and for the entirety their residency, their basement would flood when it rained. They were retired and planning on selling the house because it was just too big now. However, their realtor informed them that the state of the basement was going to bring down the value of the home as well as make it harder to sell. They contacted Rainy Day Basement Systems to help solve the problem so they wouldn’t have to worry about losing money from selling their home.

Rainy Day installed a WaterGuard sub-floor drainage system which is designed to capture water seeping through the wall/floor junction and it won’t clog with silt or plant roots. The water is carried to the SuperSump pump which has a cast iron pump and airtight lid and floor drain. The pump also includes a WaterWatch alarm system which alerts the homeowner in the event of a leak. The water is drained from the pump out of the LawnScape outlet, a buried exterior drainage line that transmits it a safe distance away from the home. Finally, an IceGuard was fitted to the discharge line to prevent it from freezing and causing flooding.

Connie and Rich were able to get their basement into a clean and dry condition, giving them confidence that their house will now sell on the market for what it is worth.

SilverGlo Wall Insulation Installation in Lummi Island Home

This homeowner had already used our services previously in 2009. We had encapsulated her crawl space and added drainage and a sump pump to rid her crawl space of moisture vapor and associated problems, such as odors and mold. Happy with the work we completed, she came back in 2013 to have more performed. In addition to the encapsulation, the homeowner wanted to add SilverGlo Wall Insulation. This moves the home’s thermal boundary to the foundation walls, making the home more comfortable and the HVAC system more effective. SilverGlo was also installed on the perimeter of the floor framing, known as the rim joist, where air infiltration and conductive heat loss are at its highest. The addition of SilverGlo Wall Insulation to this Lummi Island crawl space overall, will make the home more comfortable and more energy efficient. 

Floor Stabilization in Ferndale Home with SmartJacks

We contacted James and Lola W. after meeting them at the Northwest Washington Fair. The couple lived in a Ferndale home they had built in 1987. They mentioned the floors in their home were no longer level and wanted us to perform a free inspection and estimate. Upon inspection, we found that James and Lola’s pier pads were settling creating a void between the posts and pads. This type of settling is common in residential homes with wooden post and pier foundations and is a significant contributor to sagging floors.

To stabilize and level James and Lola’s home, we replaced all nine of their rotted wooden posts with nine of our SmartJacks. SmartJacks are highly durable galvanized steel piers that are specifically designed to stop settling. They also have an adjustable feature that allows them to raise floors back to their original level, and continue to do so if further settling occurs. 

Drainage Installation in Acme Crawl Space

Terry and Kerry T. contacted Rainy Day Basement Systems after seeing our products and services at the Whatcom Home and Garden show. The couple was in the process of preparing their home for sale and wanted the home to be as desirable as possible. At the time, their crawl space was leaking, full of critters and lacking an adequate vapor barrier. The result was rotted wooden posts supporting their home, pools of standing water and evidence of mold growing in rooms above. No one was going to buy their home with a crawl space in that condition.

To get Terry and Kerry’s home ready for the market, we had to gain control of the moisture in the crawl space. Drainage trenching is the most effective way to prevent water from collecting underneath a home. We added drainage trenching along the inside of the exterior wall footings to capture ground water and direct it towards the SmartSump we installed. The SmartSump Sump Pump is equipped with a high-quality Zoeller 1/3 hp cast iron pump with an automatic float switch. It also features the WaterWatch alarm system. The WaterWatch alarm will sound off like a fire alarm if for some reason water is flowing in from the top of the sump basin; like in the event of a plumbing leak or a power outage. Alerting the home owner about water intrusion right away gives them the opportunity to address the problem promptly, before allowing it to worsen. All the captured seepage is pumped out through the LawnScape buried discharge line where it will drain out a safe distance away from the home's foundation. Finally, we installed traditional 6-mil. black polyethylene as a vapor barrier in the crawl space. 

Lynden Foundation Stabilized with Push Piers

A homeowner in Lynden contacted us because the rear of her home faces a ravine and she noticed that part of her home had begun to settle. The home was built on a floating foundation and one corner had settled approximately three and half inches causing walls inside the home to fracture and crumble. Having purchased the home new only four years prior, the homeowner wanted a permanent solution to the problem so she could enjoy living there for years to come.

To stabilize the foundation, we installed 16 push piers to the back of the home where the settling occurred. We install the push piers by first securing a bracket against the existing footing. Pier sections are then driven hydraulically through the foundation bracket into the soil below. Pier sections are driven continuously until a suitable load bearing stratum is encountered. The weight of the home can then be transferred through the piers to the bedrock for stabilization. What is great about our push piers is that they are adjustable, and in addition to stabilizing, they can lift a settling foundation back to its original position. 

Water Damage Repair in Ferndale Basement

This Ferndale home was having problems with ground water seeping into their finished basement and the water had done damage to their flooring. The owners had a sump pump installed in the past, but it clearly was no longer working.

We replaced their inoperative sump pump with a SuperSump Pump and an UltraSump Battery Back-Up System. The SuperSump is equipped with a high-end 1/3 hp Zoeller cast iron pump capable of pumping 2,650 gallons of water an hour. The back-up system will automatically turn on if for some reason the SuperSump Pump fails to operate, like in the instance of a power outage. To direct the ground water seepage in the basement to the SuperSump, we installed WaterGuard Drainage Trenching along the interior footing of the basement walls. The WaterGuard is surrounded by gravel to filter the ground water and prevent clogging. It also features a unique flange that captures water seepage from the basement walls as well. Finally, we added a LawnScape Outlet, which is a buried discharge line that will discreetly direct the unwanted water away from the home.

Drainage Installation in Bellingham Crawl Space

This Bellingham crawl space was neglected throughout its entire existence. It wasn’t until the homeowner was having problems with raccoons and other rodents that someone informed them that their crawl space was a complete mess and full of standing water.

We installed drainage trenching in the space along the perimeter of the foundation walls to capture all the ground water seepage the crawl space was experiencing. To remove the captured water, we added a SmartSump Pump.  The SmartSump is equipped with a high-quality Zoeller 1/3 hp cast iron pump that is capable of pumping out approximately 2500 gallons of water per hour. We then replaced the filth and water covered vapor barrier with a new 6-mils. black polyethylene one.

Crawl Space Encapsulation in Bellingham, WA

Scott and Jennifer N. contacted us because they were interested in the benefits that encapsulating their crawl space could offer. We sent out a system design specialist to perform a free inspection and estimate and found their crawl space strewn with tattered insulation, pools of standing water and evidence of rodents and other unwelcome pests. These Bellingham homeowners were seeking a long-term solution for the multiple problems their crawl space was experiencing and went ahead with the proposal our inspector drew up.

To control the ground water seepage, we added drainage trenching along the interior perimeter of the foundation walls. We also installed a TripleSafe Sump Pump to empty the unwanted seepage through a buried discharge line and out the LawnScape Outlet a safe distance away from the home. We then encapsulated the space in CleanSpace, a highly durable crawl space lining that completely isolates the home from the Earth drastically reducing humidity levels. A SaniDry CX Dehumidifier was also added to further control the moisture vapor.

Upgraded Drainage System for Bellingham, WA Crawl Space

Mice, birds, squirrels, and ants were inviting themselves right into Daria and Brad S.’ crawl space. On top of that, water leakage was an issue, despite their sump pump they installed years prior through another company.

They’ve lived in their 1988 house since 1994 and wanted to call it home for many years to come, so they contacted Rainy Day.

A drainage system upgrade was in order, as well as a strategy to seal the crawl space to prevent water and pests from coming in.

First, we installed a TripleSafe pump system, assuring protection from three common problems that cause flooding: pump failure, water volume being too high for a single pump and power outage. With the Zoeller M53 and M98 pumps, up to 6,200 gallons of water per hour will be able to be pumped out of Daria and Brad’s crawl space. If the M53 primary pump fails or cannot keep up with the amount of water coming in, the M98 senses that it needs to start pumping. If the power goes out, a circuit breaker is tripped or the pumps get unplugged, the UltraSump III battery backup system will start pumping water out. With its 120amp battery, it can pump up to 12,000 gallons of water before needing to be recharged. Once the power comes back on, the UltraSump III will automatically start recharging. Additionally, the WaterWatch Probe Alarm constantly detects the water levels and will go off if water rises above the opening range of the pumps, allowing for time to solve the issue before water damage occurs.

We also installed a drainage system consisting of perforated pipe, filter fabric, and gravel that collects water from the walls and floor of the crawl space, even from soil surfaces. To dispose of the water, we installed a LawnScape Outlet and two IceGuards. The LawnScape is an underground downspout extension that will move water from the crawl space, under the ground and up through slots on the surface far away from the foundation of Daria and Brad’s house. The IceGuards are outside discharge lines that will make sure water gets disposed of adequately and safely if any pipes get frozen or clogged, since they themselves are freeze-proof, blockage-proof and operate automatically.

Next, we installed drainage matting on the floor of the crawl space, creating airspace on the ground and enabling any water to flow to the pump. We placed CleanSpace on top of the matting to give drainage space, provide a thermal break and help keep out pests. CleanSpace a 7-layer 20mil thick inorganic plastic liner with puncture-resistant and flexible characteristics, antimicrobial additives to fend off mold and thermal and vapor-proof properties.

Finishing the job, we installed an EverLast Door, giving the crawl space entrance and an airtight seal to keep out outside air, water, animals, dirt and other unwanted debris. This door is heavy-duty and will last in damp environments, never rotting, rusting or warping.

Critters and water damage from an unreliable pump are no longer issues for Daria and Brad. We look forward to seeing them at their next annual service appointment! You can view their testimonial here.
