Basement Finishing & Remodeling in West Linn, 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 finished 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 West Linn 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 finished basement that lasts a lifetime.

Job Stories From West Linn, OR
Crawl Space in West Linn, OR

We have a customer in West Linn, Oregon who had his entire crawl space flood and he had no idea what to do. Good thing he called when he did. We sent our Design Specialist Vinny out and he found that yes, indeed, the crawl space had a few inches of water in it. He explained to Steve, the homeowner, that this was no good for the integrity of Steve's home or good for the quality of air coming into Steve's home. 

We quickly had Lupe take his crew out and they were able to remove the water and insulation that had also become wet and had started to droop. They installed a TripleSafe sump pump which is the most reliable pumping system out there. They did some repair to the support posts and laid down the CleanSpace vapor barrier. 

Steve is thrilled that his crawl space no longer has a virtual river running through it and that he doesn't have to worry any longer. Steve has the piece of mind of efficiently running equipment, clean, dry air and knows that he can always count on John's Waterproofing to take care of all of his waterproofing needs.

Crawlspace; West Linn, OR

The customer wanted to invest in getting their crawlspace encapsulated. There was no damage done to the crawlspace, other than moist insulation. After removing the old fiberglass insulation they started the process of encapsulating the crawlspace. 

They started with isolating the piers, which is when we pull the moist soil out from the affected area, to make them stable once again. They then laid down a CleanSpace Drain Mat, which lays under the CleanSpace and allows the water to still move freely in the soil, without damaging or getting into the encapsulated area. 

Finishing off the crawlspace, they replaced the vents with metal covers. And installed a SaniDry Sedona to regulate the temperatures and humidity levels. To help prevent any more problems from arising they sealed it with Spray Foam Insulation. Giving the homeowners reassurance that mold growth and water intrusion would not be a problem during the spring when it starts to rain. 

Property Management Calling for Crawl Space; West Linn

Customer called to have one of her homes on a senior retirement park. She had called us because one of her friends referred us, and she liked the job we did. Her home had water starting to come in from the soil itself. And that the insulation had some water damage to it.

Making this job easier for everyone, they first dried out the crawl space. So that when they laid down the vapor barrier the moisture didn't continue to build and cause more damage. After the crawl space completed the dry out they started the process of laying down the 6 mil Vapor Barrier. They also put the SuperSump pump into place to start the process of filtering out the water from the crawl space. 

The property manager was enthralled that the job matched and excelled with the job previously done for her friend. 

Replacement Vapor Barrier; West Linn, OR

The customer called because they needed better drainage for their space and their back yard. Due to the water building up in the yard and trickling into the crawl space. 

Our crew went out an found that there was also mold growth, along with some flooding issues. They went to work by first pulling out all of the old vapor barriers and draining the water. Lupe had the crew flatten out as much as the ground as possible before installing the new 6 mil Vapor Barrier. They also installed the SmartSump pump to help catch and expel the water from the space with ease. 

Connecting it to a discharge line, that is hidden meticulously under the yard. To then have it filtered out and off the property without being seen. Giving the homeowner the reassurance that they won't have anything protruding from the crawl space. They also won't have to worry about flooding occurring from the yard into the crawlspace. 

Crawlspace Encapsulation in West Linn

Our crews recently went on a job in West Linn. The customer called about there being lots of water in their crawlspace and a damaged vapor barrier. The house had an old french drain that was not keeping up with the amount of water coming. So we sent out one of our members to inspect the crawlspace and come up with a plan. 

Eric who went out to inspect this customer's crawlspace recommended doing a crawlspace encapsulation with our CleanSpace System. We would install a TripleSafe sump pump that has three pumps to cover getting all water out and our patented WaterWatch Alarm that goes off if water rises above the range to prevent damage. Along with our SaniDry Sedona dehumidifier with a duet filter that removes mold spores, dust, and dust mite droppings. We would also install vent covers and encapsulate with our cleanspace barrier with spray foam around the perimeter of the home. 

Our customer was very happy with the solution and now can have peace of mind that water will not take over their crawlspace again.

Thermal Dry Floors in West Linn, OR Basement

These homeowners were tired of their cold, unfinished basement floor and wanted something that would look great and protect their space from water issues. Luckily, John's Waterproofing had the perfect solution! Our inspector, Jack suggested installing Thermal Dry carpeted basement flooring.


Thermal Dry Floor systems are designed specifically for basements. Basement floors are likely to be wet at some point from either a plumbing leak or a surprise groundwater leak in a heavy rain. The bottom of Thermal Dry flooring has raised pegs to create an airspace under the floor. This feature keeps water vapor from getting trapped underneath the finished floor that can cause odors and mold. Thermal Dry floors are inorganic and will not rot or buckle like wood subfloors. 


Kyle and Jen are now very happy with their beautiful new floors, and look forward to having usable space without concern of water issues.
