This homes foundation had shifted greatly. When their Old vapor barrier was installed it was not fully sealed and water was getting in. As the water penetrated the wooden posts, the homes foundation was badly damaged. We had to replace multiple piers with our SmartJack to keep the house safe.

Job Stories From Astoria, OR
High Radon Levels in Astoria, OR

This home was in a known neighborhood for having high levels of radon. After learning radon is the second leading cause of lung cancer in the USA, the homeowners wanted to test their home. They called us up and scheduled their continuous radon test. This has a test that is left for three days, on the final day a certified radon specialist goes out and reviews the radon levels recorded, showing the highs, lows, and the homes average. This homes average was at 17 pCi/L. Anything over 2.0 pCi/L is recommended to have a mitigation system in place. The homeowner was shocked to know their homes air had so much radon gas, and was ready to plan out a mitigation system. This includes a pipe that dives under the homes basement floor, to collect radon gases from the soil before it enters the home. This pipe wraps to the side of the home, and the fan is attached and pumps the radon up and over the homes roofline. Once completed we left behind a charcoal testing kit so they can check the new radon levels with a third party, showing how much of a positive change the system has instilled. 

Solving a Long-term Water Issue in Astoria, OR

When this home had been purchased, the new owners were made aware that there was a section of the basement that was perpetually damp. It didn't seem to worsen much with the rains, and only went away during particularly dry summers. The new owners decided they would find a solution though, and called up John's Waterproofing. During the free inspection we could determine that a high water table fed past the home and was extending pressure on this side of the building. We talked over some options and crafted a solution with the homeowners. 

To begin we dug a trench around the basement. Here we installed a bed of gravel and our WaterGuard drainage system. This pairs with a newly installed CleanSpace Wall system. The wall system will safely guide water down the walls into the new drain system. Here the water from the walls meets with groundwater to be guided to the lowest point of the basement where a TripleSafe Sump pump is installed. This then pumps the water safely away from the homes foundation to a LawnScape outlet. We then installed a SaniDry dehumidifier to ensure the space remains dry and healthy! The new homeowners are very pleased to have the basement addressed and not have to worry about water issues. 

Constantly Wet Portion of the Basement - Astoria, OR

When purchasing this fixer-upper, the new homeowners were informed that a portion of the basement was consistently wet. Not wanting to live with a damp and wet portion of the basement, they decided to reach out to John's Waterproofing to solve the water problem. After a full inspection, the design specialist went over their findings and suggestions to address the issue.  After knowing that the water issue could be solved, the homeowners decided they wanted to have their basement have a semi-finished appearance.

To start our work we dug a trench along the full interior perimeter of the basement. Here we added gravel and out WaterGuard drainage system. This will grade to a newly installed TripleSafe sump pump to dispel the water well away from the home. To ensure any moisture from the walls made it into this system we installed BrightWall paneling. This is easy to clean, will not mold or rot. A SaniDry dehumidifier is installed and this basement is now dry and the homeowners can use the extent of the space without the threat of water! 

Scary Crawlspace - Astoria, OR

We see some pretty scary situations in crawlspaces at times. Such was true with this crawlspace. This home was being held up with a mixture of rotting posts and posts that weren't even touching the beams. It needed some attention ASAP. Our System Designer went out and took measurements and pictures then discussed solutions to the issues at hand. Overall, all of the posts needed to be replaced and reinforced with SmartJacks and a big clean-up with a new vapor barrier. SmartJacks are made of steel and have a thick galvanized coating and are adjustable, making them a great stabilizing solution for a crawlspace. 

A crew was sent out some weeks later and got to work. They removed the old 6 mil barrier, all other debris, and got to work on installing 26 SmartJacks. With that completed, a new 6 mil plastic vapor barrier was laid on the crawlspace floor, run up the foundation walls, and fastened to keep it in its place. The crew took pictures of the finished work and the homeowner was thrilled.

Old and Damage Insulation and High Energy Bills in Astoria, OR

This home's energy bills were steadily rising. The homeowners knew their home was older, but the rise was more drastic than seemed normal. To address this the homeowners looked for ways to save on their energy bills, which is how they discovered that crawlspaces can be a leading cause of issues. Since they realized that the flooring of their home was cold to the touch, they reached out for an assessment. When our design specialist went into the crawlspace we found old fiberglass insulation falling from the crawlspace ceiling, heavy from water weight. 

To solve this issue we began by having the old insulation cleaned out. Once it was cleared, there were some mold spores found along the wooden beams of the home, where water had festered in the insulation. Since the mold wasn't very advanced we were able to clear it out with MoldX. Our installation crew then replaced each vent cover and the crawlspace entryway since they were not in top shape. Our crew then laid down TerraBlock, crawlspace-specific insulation. This was then fully encased with our CleanSpace vapor barrier. This material is 20 Mil thick and made of a woven material, backed with our twenty-five-year warranty against tears and rips. As a final piece, we added spray foam along the foundation walls and a SaniDry dehumidifier. The home will now be dry and healthy. 

Super Sump in Astoria, OR Basement

This homeowner already had a sump pump but realized that it was not working efficiently. She also wanted to make sure her basement was waterproofed because her house was for sale. Our inspector, Daniel, noticed that there was water getting into the basement and suggested installing our patented Waterguard system and a sump pump.

Once the homeowner agreed to our recommendations Tim and his team quickly went to work. They installed our patented WaterGuard perimeter drain system which collects wall seepage and directs the water to the sump pump. Bree chose to have a SuperSump sump pump installed which has a built-in alarm system for when water levels rise too high. It smoothly and quietly pumps out up to 2,600 gallons of water per hour.

Now that our systems is in place, Bree is confident that her home will sell better and that the future homeowners will not have to worry about water issues.
