Basement Remodeling in Yacolt, WA

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 Yacolt 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 Yacolt, WA
Sagging Foundation Sinking More Each Year in Yacolt, WA

Having an old house can add a lot of charm and character, but for homeowners, it can also mean more maintenance to ensure the home is safe. This homes foundation had been settling through the years, and the homeowner was aware that this issue was getting progressively worse. More windows and doors would stick or sit off kilter in their place, some areas of the floor would be bouncy and uneven. Since the issues were focused on the beams under the home, they knew that the actual foundation walls were holding up, and John's Waterproofing could assist. 

Our crew began by clearing out debris, we than began to reinforce the home. Under the home we found wooden beams rotting and cracking, we replaced these, one hundred and twenty feet total. We than looked over each wooden post, we changed out eleven posts for our SmartJacks, and added in another seven SmartJacks to give the home the added support needed. This home was now stable and sitting much better than it had in years. We then added in a 6 Mil vapor barrier to protect against water issues from harming the home. 

Water and Wood Rot under the Home - Yacolt, WA

This home had water damage under their home, the water was getting absorbed into the wooden framing of the home and rotting the wood. Because of this, portions of the floor were sloping and shifting. To keep the home from having further issues, John's Waterproofing was called out. 

Our crew safely installed eighteen SmartJacks, placed to support the home. These are metal and can adjust heights should that need ever arise. We also added in one hundred and twenty additional feet of wood beams to support the underside of the home. The dirt floor then was covered in a 6 Mil plastic vapor barrier to help keep water damage from occurring. 

Home in Yacolt, Washington Has Dry Basement

We received a call from a homeowner who wanted to make sure that her basement stayed dry. After one of her neighbors had their basement flood thanks to a plumbing leak. This homeowner wanted to take some precautions to make sure that she didn't have to deal with the same inconveniences as her neighbor. Our crew went out to the home in Yacolt, Washington to help this homeowner. They installed a TripleSafe sump pump in the basement. The TripleSafe has three separate pumps. In case the first pump fails or there is a plumbing leak, then the second pump will kick in. If it's a plumbing leak then the two pumps will work together to remove 6,200 gallons of water per hour out of the basement. The third pump will kick in if there's ever a power outage. Now this homeowner can rest assured that her basement will stay dry for years to come.
