Job Stories From Bellingham, WA
Preventing Water Damage with Full Encapsulations - Bellingham, WA

After building their own home, this homeowner recently was informed about the encapsulation process and wondered if they would benefit from having one done. They reached out to John's Waterproofing to get more information and see if it was an addition worth making. We explained that the goal of the encapsulation process is being able to prevent water from having access to your crawl space. As a result, this helps diminish moisture in the air and protects the structural integrity of the home so it will last as long as possible. The homeowner agreed that they definitely didn't want to experience any water damage in their newly built home and that an encapsulation would be best. When starting an encapsulation the first step is to install a proper drainage system. This includes installing a perforated pipe around the interior perimeter of the crawl space. It serves the purpose of collecting any water that enters the crawl space and gives it a safe passage rather than just puddling in. Then we install a TripleSafe sump pump that attaches to the pipe. The sump pump is capable of collecting all the water from the pipe and securely pushing it away from the homes foundation. Once drainage is installed, then we can insulate the space to help the home become more energy efficient. This includes installing TerraBlock along the base of the crawl space. TerraBlock is a durable, 3/4 in. thick foam that protects against moisture while also insulating the space. On top of the TerraBlock, then a CleanSpace vapor barrier gets installed. This is also installed up the foundation walls and between the concrete footing and wooden posts. This helps to isolate and protect against water by directing the flow of water beneath the vapor barrier to the drainage system. Spray Foam is applied along the foundation walls to air seal and further insulate the space so the environment can be controlled. Lastly, a SaniDry dehumidifier is installed that works to pull moisture out of the air, thus controlling the environment against humidity and mold growth. After the full encapsulation process is completed, the home is now protected against water damage.

Always Wet Basement - Bellingham, WA

In an area that experiences significant rainfall, this homeowner was dealing with water constantly coming into their basement and couldn't control the flow of it. They decided they were tired of dealing with this recurring problem and reached out to John's Waterproofing for help. We went over their options and answered their questions about how our basement waterproofing systems are different and really work to keep spaces dry and healthy. They agreed to doing a basement waterproofing and we got started.

To begin, a drainage system needed to be installed to control the flow of water and prevent flooding. This process is done by installing a WaterGuard drainage system along the interior perimeter of the basement. This connects to a sump pump that collects the water and pushes it safely away from the homes foundation. In order to protect the walls and allow water to safely travel to the drainage system, a CleanSpace wall system was installed. This thick vapor barrier has woven fibers that safely contain the water and is sealed with waterproof tape. It allows for a wall system to direct the flow of water straight to the WaterGuard taking it to the sump pump. Now their basement has a system installed to protect the basement from any water getting in.

Basement Always Seems to be Wet - Bellingham, WA

The home had an old DIY installed sump pump, that seemed to be on all of the time, yet the basement still remained wet. The homeowners were ready to see if they needed a new sump, if their current was faulty, or what the issue was for their home. So they called up John's Waterproofing and scheduled their free inspection with us. We went out and did a full inspection, and then sat with the homeowners to go over our findings as well as discuss options for repair plans. The big issue with the sump that was already installed, was it was not able to handle the amount of water that the home faced. To be able to combat the water, we had a solution. To begin we upgraded the drain system to our WaterGuard drainage system. This goes around the basements interior perimeter and ensures that water can flow freely to the new sump. For the new sump system we replaced the old one with a TripleSafe sump pump, which is built to address the amount of water that the home sees, ensuring that the water can be pumped safely away from the homes foundation. Along the walls we then installed our BrightWall paneling which allows all moisture from the walls to be safely guided down the walls to the new drain system to be addressed. We then finished by installing a SaniDry dehumidifier to keep the moisture in the air controlled so mold and mildew cannot grow here. Now the space is ready for the rains! 

Crawl Space Repairs for Bellingham, WA

This home had a crawl space that housed an old and torn 6 mil vapor barrier. Over the last few years this has shifted out of place and had mud encased over it . The homeowners could smell the damp earthy aroma from their living spaces above. They knew to get rid of this smell they would need to get some sort of help, and they turned to John's Waterproofing. We began by installing a full drain system within a silt sock around the perimeter. This will collect groundwater, channeling it toward the lowest point of the crawl space. From here it will enter a newly installed UltraSump Plus and be discharged away from the home. Each vent was sealed shut and we installed SilverGlo paneling along the walls to begin insulating the space. Along the dirt floor we installed our TerraBlock insulation and then layered over this with CleanSpace. This is a 20 mil woven vapor barrier. It is installed under each wooden post, anchored along the foundation walls, and then sealed into place. A SaniDry dehumidifier was installed to address moisture issues in the air. Now this home can enjoy healthier air throughout the living space. 

Partial Crawl Space and Basement Waterproofing in Bellingham, WA

This home has a large crawl space with a partial basement under their home. The crawl space had a vapor barrier that was out of shape, and layers of dirt through it. When the rains hit it would smell damp and musty and the wall between the spaces had water creeping through it. The homeowners were ready for something that could transform these spaces into dry and healthy pieces of their home. For this they called up John's Waterproofing so they could receive their free inspection and estimate. 

To begin with this home, we would encapsulate the crawl space. We installed a full drain system with a TripleSafe sump pump at the lowest point. We then insulated this area, using TerraBlock along the dirt floor and SilverGlo along the foundation walls. CleanSpace was then installed, which wraps under each wooden post, anchors and seals along the foundation walls, and each seam is sealed using a four inch wide waterproof tape. As a final step in this are we installed a SaniDry dehumidifier. In the basement section installed a WaterGuard drain system which will channel water to the TripleSafe sump to be pumped away from the home. Along the walls we installed our CleanSpace wall system. The owners were happy to note that the space already smells cleaner and they look forward to enjoying healthier air within their home. 

Moisture and Water in the Basement - Bellingham, WA

This homes basement had some humidity issues. The owners knew that it was an issue as the space would smell damp most of the year, and during the rainy season there were small puddles of water that would appear along the floor. The owners wanted to find a solution that would help the space to be dry all of the time and address the damp odor, so they scheduled with John's Waterproofing. 

To begin we dug a trench around the homes interior perimeter. Within this we laid a bed of gravel and our WaterGuard drain system. This will ensure moisture from the walls as well as any groundwater will have a channel that will guide it to the lowest point of the basement. From here water will enter into the TripleSafe sump pump and be pumped away from the homes foundation. Along the walls we then installed our CleanSpace wall system. This is a vapor barrier that will not rot or mold, just safely ensure any moisture from the walls is able to travel down the walls to be addressed. As a final step we then installed our SaniDry dehumidifier which addresses the moisture content in the air, keeping it at a healthy level and removing that damp odor in the process.  

Basement and Garage Waterproofing - Bellingham, WA

This home was built into the hillside, with a garage in it. This space had cracks along the floor where water was coming up through the foundation floor. Over the course of about two years, these cracks were letting in more water and small puddles would form when heavy rain occurred. To get the space dry, they called up John's Waterproofing to help craft a repair plan. To begin we dug a trench around the spaces interior perimeter, including where the garage door goes. We also dug out two leech lines to address where the cracks were resting. We laid gravel in these. The leech lines received a perforated pipe, along the garage door we installed TrenchDrain, and the rest of the perimeter had WaterGuard installed. All of these will work together to collect groundwater and provide a track for the water to travel along the lowest point of the space where a TripleSafe sump pump is then installed. This then pumps the water safely away from the homes foundation to a LawnScape outlet. Along the walls we then installed BrightWall paneling where the wall sits below-grade to ensure any moisture here is then safely guided to the drain system as well. We finished off by installing a Dehumidifier to keep the spaces moisture content in the air controlled. The homeowners are happy to have this space waterproofed and healthy now. 

Needing a Basement Inspection - Bellingham, WA

This homes unfinished basement had water problems popping up. What had began as a faint damp odor had grown into water trickling down the walls in three spots around the room. The homeowners wanted to get a grasp on this issue before it became a bigger issue so they called up John's Waterproofing and scheduled their free inspection. Once out we did a full interior and exterior inspection and then crafted a solution with the homeowners to address all concerns. 

To begin we would have to address the homes below grade windows. Water was building up in the wells and the coming through the foundation walls beneath these. For these we dug the window wells down, installed a drain pipe through the wall and then added in rock up to the base of the window to help with drainage. From the inside of the space we then dug a trench around the homes interior perimeter. This houses WaterGuard, a drainage system that will collect water and guide it to the newly installed TripleSafe sump pump to pump water away from the homes foundation. The walls were covered with BrightWall paneling, this ensures the water from the window drainage will be guided down to the WaterGuard, as well as any other moisture from the foundation walls. A dehumidifier was the final step to ensure moisture in the air is also addressed, ensuing this space can remain dry and healthy all year round. 

Finished Basement with Water Issues in Bellingham, WA

This home finished basement was showing signs of a water issue. The lower portions of the drywall were bubbling with water and squishy to the touch. The homeowners knew an issue must be festering behind their walls and wanted to get it properly waterproofed so they could keep the space usable and healthy. While they would do the refinishing of the space, they did want to have a professional do the waterproofing portion. So they called up John's Waterproofing for a free inspection. Afterwards we get over products and put together a solution. 

To begin we had to remove the damaged portions of the space. This meant taking down the drywall on the exterior walls, pulling out the fiberglass that was damp and musty, and pulling the flooring back from the walls so we could install a waterproofing system. We then cut the framing and used a jackhammer to create a trench around the basements interior perimeter. Here we laid down a bed of gravel and our WaterGuard drain system. Water will be able to travel through this to the lowest point of the space where a TripleSafe sump pump is installed and will then pump the water safely away from the homes foundation to a LawnScape outlet. On the walls we then installed our ThermalDry radiant vapor barrier, this provides a thermal break from the foundation walls and is a vapor barrier, ensuring any moisture from the walls in directly to the new drain system. We then installed a SaniDry dehumidifier to keep the moisture in the space controlled. Now the space is waterproofed and ready to be refinished. The homeowners will be able to enjoy some peace of mind. 

Falling Fiberglass in the Crawl Space - Bellingham, WA

This homes heating bill was rising faster than it should have, and their floors were abnormally cold under foot this year. They looked online and learned this can be due to poor insulation in the crawl space. They knew they had fiberglass under their home, so they glanced under the home to get a better idea of the problem and saw that it was falling from the subfloor and the entire space emitted a damp odor. So they called up John's Waterproofing and had a full inspection, and chatted with their design specialist about options. 

To protect the home from crawl space issues, a repair plan was built for a full encapsulation. To begin we removed the old insulation, dusty old vapor barrier, and general debris. We then sealed shut the old vents and installed a full drainage system under the home. This provides a pathway for groundwater to go to the lowest point of the space where a TripleSafe sump will pump the water away from the home via a discharge line. We then insulated the dirt floor with TerraBlock and installed our vapor barrier. This is a CleanSpace vapor barrier that is 20 Mil thick, it goes under each wooden post, anchors to the rim joist, and is sealed along each seam with a four inch wide vapor tight tape. A SaniDry dehumidifier was installed and we finished insulating the space with Spray Foam along the foundation walls. To complete the job we changed out the old plywood exterior door with an EverLast door. The homeowner is excited to enjoy a cozier home and lower heating bills this winter. 

Wet Mess in the Crawl Space - Bellingham, WA

This home was built onto the hillside and water would pool in the lower areas. They had another company install a sump pump but it was not able to keep up with the water present and the space had pooling water whenever heavy rains came through. Since they wanted to keep the space dry all of the time, this wasn't cutting it, and they scheduled their free inspection with John's. We begin on this job we pulled out the old vapor barrier and the sump pump. It had debris in it and was in bad shape. We then installed some drain systems along this lower section, allowing all water to flow down the hillside and once it hit this drain system it would have a direct route to the newly installed TripleSafe sump pump that would then pump the water safely away from the homes foundation. TerraBlock insulation was then installed along the dirt floor and we sealed the vents shut. CleanSpace was installed next, this is installed under each wooden post, attaches along the rim joist and is sealed along each seam. This is a 20 mil thick woven vapor barrier that comes with a 25 year warranty against rips and tears. A SaniDry dehumidifier was installed to address moisture in the air and finally spray foam insulation was applied to the foundation walls, both insulating and air sealing. This space is now able to remain dry and healthy all year round, just like the homeowner really wanted.
