Recent Earthquake Retrofitting Reviews in Portland

  • NW Seismic
    5.0
    NW Seismic made a very easy process for estimating and installation. Their drywall and plaster work was particularly well done. They also made some excellent recommendations regarding natural gas shut-offs and securing our water tank. Very professional from beginning to end. Would hire again anytime

  • TerraFirma Foundation Systems
    5.0
    Excellent to work with! They arrived on schedule and completed the work on schedule and on budget, even though they had to adjust their work to compensate for the lack of room in the crawl space. They are not cheap, but they did the job very well.

    Excellent. Can't recommend NW Seismic enough! They were timely, clean, and kept me in the loop of what they were doing. The permitting process was seamless and they provided a set of pictures for my records. Great company from top to bottom.

  • TerraFirma Foundation Systems

    Crew arrived on time. Very professional; explained what they were doing. Had to revise the project due to crawl space issues, which required them to cut notches out of the bottom lap of our siding to install their plates. They sent a carpenter the next day to glue the notches back in place.

  • TerraFirma Foundation Systems
    5.0
    From the "system design specialist" who evaluated the problem through the completion of the work, everything went very smoothly. As is often the case with older houses (1923) there were surprises, but the experienced Terra Firma crew was able to adapt and complete the system on time and on budget.

  • TerraFirma Foundation Systems
    5.0
    TerraFirma did a fantastic job, working hard all 5 days on the job. One of their carpentry specialists was needed to complete most of the job, and he certainly went above and beyond, in my opinion. He and his teammate really cared about securing our home. The one hangup I had was the communication about what some of the next steps were. The original crew that came did a full day's job, but realized the situation was was more complex than first thought, so they weren't sure when the project would pick up again. Luckily it was only a few days before the carpenter came out to continue

    I like working with people who are frank. "This is going to be really loud." And it was! But now we feel more comfortable that we had a top-notch company retrofit the house. They were very professional and when they left, the basement was cleaner than when they came.

    Very well! The team at my home was responsive, professional and they listened to us when we had concerns.

  • Evolution Home Improvement
    5.0
    Really well. Jim takes time up front to be sure he knows my needs. Scheduled work and kept to the schedule. Professional and cleanen up the site each day. We needed to change up a work approach when the original plan would not be effective. Jim adapted and the change actually saved some money.
    Brian R.
  • NW Seismic
    5.0
    Needless to say, this was a huge job (6+ weeks). Given how much can go wrong with something at this scale, it went remarkably well. We were able to use our house 100% the entire time. They worked from precise engineering drawings and specs using a top notch engineering firm, and also adapted to the inevitable unexpected. There were some minor change orders that upped the price a little, but all reasonable. They built the footers, rebar, blocking, and other reinforcement to a very high standard - well beyond what would otherwise pass as a foundation build. A few minor negatives, but nothing that would stop me from hiring them. Communication prior to the job start was not good. As for the quote, don't expect detailed line items and descriptions about what is and isn't included. But they are honest and straightforward, so in a sense, this can work just fine if you're comfortable without documentation and can roll with some on-the-fly decisions. Big jobs on old homes inevitably require this. Also, I don't know that I would have them do extensive finish work, especially if you need much of your basement interior restored after the work. The restoration of some electrical (ceiling lights, circuits) and basement sink was kind of sloppy. My sink is still out of level. But as for replacing a foundation and reinforcement, they really know what they are doing. The other items are minor
