John's Waterproofing Company also deals with a lot of mushy, wet, flooded yards. This homeowner called us out to help take care of the water in her yard, this water was flowing in and building up under her deck causing it to also drain into her crawlspace! Our team came out and dug a trench drain around the home. We then put piping and rocks in the trench and use gravity to direct the water out of the yard, effectivly preventing this home from being a lakefront property.

This daylight basement was always leaking water, especially at the door due to no drainage. Our crew installed a TrenchDrain in front of the basement door so that the water can never reach inside the basement. It is made of reinforced plastic so that it will never crack or dent. The trench drain is easy to clean out so that you don't have to worry about clogged drains. The homeowner likes how clean it looked and flush with the pavement and can keep up with the amount of rain that is present!

Basement Remodeling in Saint Helens, 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 Saint Helens 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.
