NW Seismic

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.

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.

Tim and his crew were upfront and communicative throughout the entire process. They did a really good job of explaining what to expect and how it would go. The onsite project manager was great in his communication. Kept me up to date. And the crew was fantastic, especially the crew lead, who was very thorough in setting up plastic to protect the space, and did an amazing job. He clearly takes pride in his work, which I always appreciate. They were also consistent about following COVID-19 prevention measures, which is a top consideration for me these days. We had to have old wood paneling removed, and the crew was able to re-install it, which was not part of the original contract. They did a fantastic job, and I'm really happy with the result

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.

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.

We are really grateful to have found this company at a disaster prep fair in Multnomah Village. Tim Cook is very knowledgeable, not loathe to explain what can and can't be known (perfect sign of a real pro!). Sarah Turner in the office is unfailingly pleasant, efficient and responsive. The gentlemen who did the work in the crawl space arrived exactly when they said they would and were meticulous workmen - including in preventing any mess and caring for our home. (Seriously - the hallway they traversed may have been cleaner after they left!) Joe, who installed a gas meter shut-off was terrific - on-time, thorough, careful. Lots of integrity in this company.

My sister had used NW Seismic for her retrofit some years ago. When I finally got around to looking for estimates, I really appreciated their online scheduling. Even better, when I finally had the money almost a year later, the prices had not changed. I was worried about scheduling, because the workers would need access to various parts of the house which would make it difficult to keep our dogs out of their way. However, someone came to my house to look at options and help me figure out something that would work. They got us on the calendar at our convenience. When the workers came, they were prompt and efficient; even the inspection went by in a blink. All my emails and questions were answered quickly and pleasantly. Overall I'm very happy with the work done, and how quickly and painlessly it was done.

The estimator, Tim, showed up on time and was very professional. He explained in detail what work he would recommend and what was unnecessary (e.g. our 1998 addition did not require retrofitting). When the work began, Jose and Genaro showed up on time and worked diligently to complete the work. All of the hardware and the gas valve were installed the first day and the next day was dedicated to repairing drywall cuts in our basement. The project manager, Sarah, stopped by to check out the progress. The crew did a wonderful job and even repaired some other drywall damage and re-secured our water heater free of charge! And the work areas were spotless when they left. Highly recommended!

A very professional contractor. All planning and work was clearly defined, and notices and follow-ups were timely and accurate. Fair pricing, no surprises. I can't think of a single negative.

The project went smoothly, and all the personnel we dealt with seemed like wonderful people. The quality of the work was excellent.

Our home was built in 1930 and has required a lot of attention over the years. This company, by far, was one of the easiest and most professional experiences we have had. They came out the day after I called for the estimate. Our estimate was exact (that never happens nor do I expect it anymore) and the team arrived at the exact time they said they would. The job was completed on time and they were very respectful of our home. The inspection occurred the next day. I expected more of a mess but they cleaned up well! I strongly recommend this company.

A representative came to our home (built before modern earthquake codes) to give us an estimate for retrofitting our home. He patiently and thoroughly answered our questions and was very knowledgeable. After looking under our home, he let us know that our home was already very structurally secure and that adding brackets would not make it more stable in an earthquake. We were thankful for his honesty, and felt confident in his knowledge.

I have been looking for someone to advise me on whether our house needed attaching to the foundation (to resist earthquakes). NW Seismic was by far the most knowledgable. They also gave me the best advice. An example - one other provider told me that the exterior of the house was ok, but that we could attach the interior posts to the house (for a cost of $5,000). When Tim came to check out our house, he mentioned that there was no need to attach those posts - that there was no record of post failure causing a house to collapse. He said the most we would need to do , if anything, was to add some connections to the ends of the house. We decided to do this. He showed me examples, explained what they would do. We scheduled the work, the crew showed up on time, completed the work on time, cleaned up completely. My husband went under the house to see what was done, he was impressed that they did the work so well - especially on the parts that were hard to get to. I was very happy NW Seismic!

Very quickly and efficiently. Great crew , fast and good mannered. Work involved different solutions to suit home design in order to bolt our home to its basement walls. They cleaned up nicely after their work.

After an inspection, they recommended some additional support for our second story over the garage and an earthquake shutoff for the gas line. We authorized them to do the work. They let us know that it would take a while to get to the job, and we had no problem with that. In fact, they came within the time estimate. The structural work was done professionally, and we are quite satisfied with that. They sent a young man to do the gas line. Afterwards, over a period of time I occasionally smelled a whiff of gas from the line, but thought that might be normal. I eventually decided to have NW Natural come out to check it. They informed me that the pipe NW Seismic installed was leaking gas and fixed it. I understand that NW Seismic now has a new person doing gas shutoffs, so maybe this will not reoccur, but feel that a gas leak is dangerous enough to warrant the B rating.

Their estimator came and did a thorough estimate, which he promptly emailed to us. The estimate was conditional on our foundation being sound enough for the anchor bolts to be effective. When NW Seismic sent their workers to test drill our foundation, they drilled and refilled holes in three basement walls. The test indicated that the foundation was not solid enough to hold the anchors. We very much respect the honesty and high standards of NW Seismic, so we had them install an earthquake actuated gas shutoff valve. They did that beautifully and made sure all our gas appliances were working afterward. The reason that we called NW Seismic initially is that we had seen their excellent work anchoring a friend's house. Seeing the great work they did on their house and that they were unwilling to install on an unsound basement in our house gives me good reason to recommend them to any homeowner considering a seismic retrofit.

It went well. They explained what they were going to do and why. They arrived on time, did the work, checked in with us at the end. Really glad I went with them!

Super smooth install, would answer any questions I had while they went along.

Summary I’ll only briefly summarize what ended up being a 17 month long ordeal and one of the most negative service experiences we’ve ever had. While we were initially very impressed with Michael’s confidence and clear expertise in the field, we found that this ultimately didn’t make up for very poor communication and very poor “bedside manner.” We had extended a lot of positive intent toward Michael, assuming much of his communication delays were due to his heavy work schedule, but we can now only assume that Michael was valuing other projects over ours. His final estimate ended up exceeding a competing company's solution (by more than $10k), despite him originally highlighting how his solution was better, and more economical than theirs. Most importantly though, the reliability and clarity of communication from him was absolutely terrible. For these reasons we can strongly say that we cannot recommend Michael and NW Seismic to anyone. Timeline * 3/11/15 - Initial site visite and verbal estimate ($50-60k) * 6/23/15 - Michael indicates likely start date is Spring, ’16 * 4/15 - 1/16 - Michael is slow to respond to emails and unclear regarding the engineer’s site visit requirements; most times his replies are delayed by several months. * 2/9/16 - We finally get an update that we’re “number 9 on the list.” * 5/30/16 - Spring arrives so we check in to get an update on schedule… no response until… 2.5 months later. * 8/15/16 - Michael sends a written estimate of $76k “to reflect current costs,” though this represents a 40-50% increase from the original. He notes that he understands if this causes us “to change [our] priorities.” * 8.15.16 - We reply via Email that "we're feeling significant 'sticker shock'" and "need time to digest" * 8.16.16 - We reply that “our priorities haven’t changed” and that “we are in complete disbelief over the increase,” We explained that his bid is way over competing solutions and we “waited patiently for a year and a half” and request that he reconsider his estimate. * We’ve received no response from Michael… to this day (5/26/17)

This company was ON TIME, PROFESSIONAL, and very KNOWLEDGEABLE. Ryan made sure we knew what to expect and when. The workmen were thoughtful and industrious. When they left, our basement was cleaner than when they arrived!! They also do great outreach work in the community. We highly recommend their seismic refitting services.

The work was great. The scheduling was terrible. They promised a 1 day job, and then when they didn't finish, said they'd be back the next business day (so, my basement was unlivable all weekend. I live in my basement.). They called when they were supposed to show up saying they weren't going to make it. not much in the way of apology. I was unable to get them to come back to finish for 10 days. So, my house was torn up that whole time. Would not recommend them based on this.

Excellent. Very knowledgeable, professional, and responsive.

They booked us months out -- they're busy. But they stayed in touch, then came when they said they would. They stuck to their bid (plus add-on for dry rot.) They're not cheap, but they re-engineered as they went, they were friendly and flexible, and it was obvious their entire objective was to have our house be speak for their work in the event of quake. The wall in the picture is an example of something they totally rebuilt.

They were really expensive. They showed up on time for the bid.

They did great, they did an excellent job. I have used them twice already and I used them another time.
