This customer's home was built in the '70s and they used the basement as their master bedroom. Over time they have noticed that the waterproofing materials were disintegrating and water was starting to seep into the basement. We demoed half the basement wall that was water damaged and put in our basement wall system. We first put up ThermaDry wall that helps keep warm air in to save on basement heating costs. For a nice finished look, we put in our EverLast Wall Restoration that is compatible with our WaterGuard basement drainage system. The customers were so happy that the basement will no longer leak water but they also have an updated look to the basement.

Basement Remodeling in Amity, 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 Amity 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 Amity, OR
Amity, OR House gets New Vapor Barrier

This Amity homeowner was dealing with falling insulation and water intrusion. This lead to her home being colder and less healthy. After inspection, our inspector Kevin suggested installing a Smart Sump pump, Spray Foam Insulation, and our patented Clean Space system.

Manuel and his team quickly set out to fix Sarah's wet crawlspace and inadequate insulation. They installed our airtight Spray Foam Insulation which serves to insulate and acts waterproofing. They then installed our Clean Space vapor barrier system which reduces moisture and humidity, while also improving home comfort and energy efficiency. The team also put in a Smart Sump pump with an Ultra Sump backup battery so that in case of a power outage, the Smart Sump will continue to do its job. A SaniDry Sedona Dehumidifier was added and it our service team will come do a  yearly maintenance it to ensure that it is functioning to its fullest potential.

Sarah was extremely pleased with her new system and now enjoys a healthier, cleaner home. She no longer experiences cold drafts from her crawlspace and is very happy with our customer service.
