These posts in the crawlspace were full of moisture, causing them to weaken from wood rot and not hold the house up properly. That is where we came in with our Smartjack product and replaced the posts. Now they are stable and strong and have no risk of rotting out from moisture.

Basement Remodeling in Deer Island, OR

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly remodeled basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include:
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average Deer Island contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive basement that lasts a lifetime.

Job Stories From Deer Island, OR
Flooded Basement Rendered Useless - Deer Island, OR

When a home has frequent flooding, homeowners might just render the flooded space useless. That's what happened to this home, but it wasn't just a little space, it was the entire basement. Due to how often it had water issues and the severity of the water, the basement was left empty at all times. After a while though, the family needed more space, instead of opting to buy a new home, they wanted to add storage to their current home so they could free up room in the main portions of their home, so they called John's Waterproofing to reclaim their basement. 

To begin we dug a trench system around the interior perimeter of the home, We then inserted out the WaterGaurd drainage system to collect the groundwater. We also installed a SuperSump pump and UltraSump pump backup so that the water could be collected and pushed a safe distance away from the foundation of the home. The basement was now dry and healthy, adding a lot of space for the family to use! 

Basement Waterproofing - Deer Island, OR

The home had an issue with annual flooding in the basement. There was water leakage around the pipes that went into the basement cement walls, and the basement had to remain cleared out since it was common for minor flooding to occur when the rain hit. The home owners were ready to regain their basement and have usable space once more. 

The homeowners were not looking for a Total Basement Finishing, but they did need full waterproofing installed. We added in a Waterguard pipe system on the interior walls of the basement all connected to a SuperSump and UltraSump. With the amount of water the home experienced, we wanted to make sure their home would be fully prepared for whatever would come. With this job completed we could ensure that all of those old pipe fittings wouldn't be allowing water access to the unfinished basement we were building. 

Once our team was done, a waterproofed basement was created, the homeowners wouldn't need to worry about flooding and they could use the basement for storage and know their home goods would be safe against the elements!
