Title: System Design Specialist

Mike O'Brien from TerraFirma

Mike O’Brien’s career has taken him everywhere from aviation to concrete repair. Along the way, Mike’s developed a vast amount of knowledge to help homeowners with their home foundation, basement and crawl space issues.

 

Mike also has a robust background in recycling and manufacturing. As a System Design Specialist, Mike’s conscientiousness of our effect on the environment is ever present when he’s diagnosing problems and providing solutions to homeowners that are safe for their home and the earth.

 

Before and after photos from jobs I've worked on:
  • Crawl Space Encapsulation in Keizer, OR
    Before
    Crawl Space Encapsulation in Keizer, OR
    After

    This Keizer crawl space had seen its fair share of rough winters and heavy rains. Year after year, this crawl would be holding in rainwater, and eventually, mold was starting to produce.

    Our System Design Specialist, Mike O'Brien, quickly scheduled an appointment with the homeowner as soon as they called TerraFirma. After spending more than an hour in the crawl space, he concluded that to prevent water damage; the area would need to be encapsulated with drain tile, and 120 mil thick VaporLoc Elite liner.

    Along with encapsulating more than 1,000 square feet, Production Foreman Brad Peterson and his crew also removed the old, wet, and mildew-ridden insulation that was doing more harm than good.
