We are experts in all things basement and crawlspace. Given this fact, we are not always completing standard waterproofing. Sometimes it is details such as this ThermalDry flooring that make the space more beautiful while providing necessary function. This flooring is raised from the concrete providing a 1-inch thermal barrier that will keep the basement warmer and prevent ground moisture from reaching your space.

It is amazing what a clean space can do for your family's health and the ability to fully take advantage of a space. This homeowner used our thicker CleanSpace vapor barrier for the area he plans to use for home storage, and then the thinner 6 mil plastic in the areas without foot traffic. This will give them great moisture protection as well as large usable space.

Basement Finishing & Remodeling in Sherwood, 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 Sherwood 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 Sherwood, OR
Clean Space the Neighborhood; Sherwood, OR

Nelson called us to encapsulate his crawl space after seeing our job well done on his neighbors home. He, however, didn't know just how lucky he was to call us at the time he did. His home was infested with mold in the crawl space. With 50% of the air, he and his family were breathing was coming from the crawl space. 

So our first course of action was to clean up all the mold and prevent it from coming back. And to do so we used our two-step Mold-X. Which cleans and seals the walls and posts from the spores growing again. 

Which made it so that when we started the installation of the TerraBlock and CleanSpace we wouldn't be locking it in and letting it flourish. Francisco and his crew also made sure to replace seal up the vent covers so that no new liquid could travel into the crawl space. 

With the vents covered, the customer was curious as to what would regulate the humidity levels. We reassure him everything would be fine, as we installed the SaniDry Sedona dehumidifier to regulate all humidity issues. And temperature fluctuations that may start due to weather changes. 

They also had the TripleSafe sump pump installed, which has a separate generator to power on in case of power outages. That would pump the water out of the crawl space completely. Leaving the customer satisfied knowing that they wouldn't have to worry about it not working randomly. 

Standing Water Transformation in Sherwood, OR

This customer called with concerns about the standing water in her crawlspace and what damage it was causing. She gave us a call for an inspection and to see what her options were to fix the issue. 

Our inspector went out and recommended we do a crawlspace encapsulation to secure and protect her crawlspace from water damage. Our crew went out and removed all the sagging insulation and old ripped vapor barrier. We installed our TripleSafe sump pump that has three pumps to ensure the high capacity of water drainage along with a WaterWatch Alert system that will sound off to notify you if there is a leak or any other issue to avoid minimal damage. We also installed a SaniDry Sedona dehumidifier that will keep the air clean of mold spores and dust mites but also keep the humidity down to avoid moisture in the crawlspace. Then we seal it closed with our CleanSpace liner that keeps water out and puncture resistant. 

She was so happy to have a dry crawlspace and not have to worry about water again. She can now enjoy her home knowing they are breathing clean air in the home.

Vapor Barrier Combination in Sherwood Oregon

This homeowner had a dirty and ripped vapor barrier that we came in to replace. Since they had such a large space they wanted to be able to use their crawlspace for storage. The homeowners were not quite ready to commit to a full encapsulation though, so they opted to use our 2o mill thick CleanSpace in the area in which they will be storing items and the thinner 6 mill plastic in the areas that do not get foot traffic. This allows them a sealed and usable space. 

Here at John's Waterproofing, we pride ourselves on our ability to be flexible without compromising safety and home health for our homeowners.

We need a vapor barrier installed in our crawlspace.
Vicinity of SW Roosevelt Street in Sherwood
We have a daylight basement on a sloping lot. It appears water is coming in under the foundation. The builder installed a sump pump in the lowest corner and it runs almost continually during the winter. There is also visible water running along some upper foundations in the crawlspace during heavy rains. There can be a moist smell in the basement when it is raining. Our backyard seems to be overly saturated in the winter too. It looks like bad drainage all around.
