Basement Finishing & Remodeling in Keizer, 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 Keizer 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 Keizer, OR
Clean Crawl Space, Keizer, OR

When Martha found out that her respiratory issues were because of mold she knew she needed to make sure there was no mold in her home. That's when she called for a free inspection of her crawl space with Vincent who did find standing water in places and some mold forming. Shortly after Tim took his crew out to her house, cleaned out all of the old materials, found where the water was coming in at, installed a sump pump, and did an encapsulation. 

Encapsulating your crawl space seals off all of the vents eliminating the chances of dust mites, moisture, allergens, and bacteria to form. Giving you a dry, clean crawl space for a very long time, which also means cleaner air entering your home. 

Martha is very happy with the results. She is definitely happier having the peace of mind knowing that she is breathing cleaner air. We are always happy to help here at John's Waterproofing.

New vapor barrier in Keizer Oregon

This homeowner in Keizer Oregon called because she was afraid that she may have water in her crawlspace, but she wanted to be sure and handle it quickly if she did. Our inspector Vincent Birchall provided her with a free inspection and did confirm for her that she did, in fact, have puddles of water, eroding posts, and mold in the beams of her home. He provided her a written estimate to solve the problem which she quickly accepted. 

Gordon and his team were given the job of turning this scary space into a cozy place. They removed the old vapor barrier and ripped fiberglass insulation as well as replaced the molded and rotting posts scattered through the foundation. They then installed a perimeter drain, a sump pump, a dehumidifier, and our patented CleanSpace vapor barrier. Fernando finished the space with our spray foam perimeter insulation ensuring a warmer and more comfortable home for decades to come.

Soggy Crawl Space, Keizer, OR

Darryl gave us a call here at John's Waterproofing because he had seen that there were some definite signs of water in his crawl space and noticed some soggy, sagging insulation. Darryl suffers from some respiratory issues and was concerned about his health and the health of the air coming into his home. Did you know that half of the air on the first level of your home comes from underneath your house? Darryl knows this and how important it is to have clean air. 

Daniel M, one of our Design Specialists went out to Darryl's home and inspected the state of the crawl space. He did see puddles water here and there and there was sagging insulation that had become waterlogged. Our Foreman Gordon W. took his crew out and they got to work on cleaning out all of the old material and equipment that wasn't working properly. They put in a SaniDry Sedona Dehumidifier which eliminates all moisture. They then installed a SnaiDry Sedona Smart Sump pump, repaired some damage to the posts caused by water and then did a full encapsulation of the crawl space using the CleanSpace material and added some Spray Foam to the walls of the crawl space. 

Now no air comes into the crawl space or gets trapped in there. And Darryl now has only clean air coming into his home. Darryl says that his breathing has improved and he is happy knowing that his crawl space is guaranteed for many years. And is helping him save on his energy bill.  

CleanSpace, Keizer, OR

We have a customer named Art in Keizer, OR who called in one day with concerns about moisture in his crawl space and was worried that with the heavy rains, and not maintaining his crawl space that there might be some damage to his structure. This is just the sort of thing that John's Waterproofing specializes in so we were hap[py to help. We sent out our Design Specialist Vinnie B. out to take a look. Vinnie crawled underneath Art's house and did see there was some water damage to the posts supporting Art's home and found some mold. 

The project was scheduled quickly and we had Fernando H. and Delfino G. go out to fix the issues. They were quickly able to repair the water damage to the posts and did a full encapsulation of the crawl space for Art. The whole job was completed within just a few days. Art was thoroughly impressed and was delighted to know that he no longer has to worry about any further moisture coming into his crawl space or affecting the integrity of his structure. He also knows that he can call John's at any time with any concerns he might have and that our crews will be out once a year to maintain his crawl space so he doesn't have to. As always, we were happy to help. 

Crawlspace Make over in Keizer, OR

These homeowners had been using this home as a rental and were ready to settle for retirement to return home. After the renters had moved out they noticed that the home had a weird smell constantly in it and the heater always was running. They weren't sure what the issue was but found us and decided to give us a call for an inspection. 

Upon inspection, our inspector found that rodents were getting into the crawlspace. The rodents had ruined the fiberglass insulation and it was hanging down. There was also some standing water in parts of the crawlspace due to high humidity levels causing moisture build up. Our inspector recommended that we do a complete crawlspace clean out and install our Cleanspace encapsulation system. The crews first cleaned out all the debris, old torn vapor barrier, and removed all the sagging fiberglass insulation. After we had the crawlspace cleaned we put down our Terra Block crawlspace insulation that goes on the dirt floor below the vapor barrier. We seal each vent and place a nice airtight vent covers over each one. We install our CleanSpace vapor barrier that is 20 mils thick and rip resistant. Which will help a lot since rodents were known to get into this crawlspace and cause damage. After everything is sealed we use our spray foam insulation around the parameter walls to give more coverage. Due to some moisture, our crew also installed our SaniDry Sedona dehumidifier that is perfect for the crawlspace to keep moisture out and cycle clean air up thru the home. 

The homeowners were so relieved that they didn't need to worry about their crawlspace anymore. That they were breathing in clean air and after a couple of days the musty smell left the home completely. Along with encapsulating your crawlspace, they will start to see a decrease in their heating and cooling bill. Air is no longer escaping out of the crawlspace now with proper insulation and sealed.
