Basement Remodeling in Otter Rock, 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 Otter Rock 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 Otter Rock, OR
Cracked Foundation and Water Issues in Otter Rock, OR

This homes foundation had a lot of issues that had let to extensive water damage under their home. The homeowners had our friends over at Ram Jack do the structural repairs, but needed someone to come in and waterproof the crawlspace so they home would be protected, so they were referred to us at John's Waterproofing. 

Our crews arrived and began by removing the water saturated fiberglass insulation and the debris from the crawlspace. We than addressed the major waterproofing issue; downspouts dumping water beside the home and water pooling by the garage door and getting stuck alongside the home. We installed a TrenchDrain along the garage door, this would collect the water and run it along a new buried pipe system. This pipe system connected to the downspouts and than pushed all of the water out and away from the homes foundation and safely to a LawnScape outlet. We than went back under the home to properly insulate this crawlspace. We installed out TerraBlock insulation over the dirt floor, this was than encased by our 20 Mil thick CleanSpace vapor barrier, which wraps around each post and is anchored along the walls. Finally we added spray foam along the foundation walls. This home is now structurally sound, and will be dry and healthy!  

Healthier Crawl Space for Home in Otter Rock, Oregon

We received a call from a homeowner in Otter Rock, Oregon who had concerns about the air quality in her home. There was a musty and damp odor in throughout the house. Our crews went out to the home to help. The problem was originating from the crawl space. Air travels up so air with mold spores or other allergens from the crawl space will make its way up to the rest of the home. Our crews removed all debris from the crawl space and then installed CleanSpace encapsulation system on the walls and floor of the crawl space to prevent moisture or water vapors from coming in. This means no new mold growth. They also installed a SaniDry Sedona dehumidifier in the crawl space. The SaniDry Sedona eliminates damp and musty odors by drying and filtering the air. It's the most efficient dehumidifier in the world and plenty powerful enough to keep the home's humidity levels below 55% so mold and dust mites won't stand a chance. Now this homeowner can breathe easy with cleaner, healthier air in her crawl space and home.
