It went well. The estimator came out and educated me about retrofitting. I went under the house with him and he educated me about my home's foundations. I was not required to go under the home, in fact he said that most homeowners don't go under the home with the contractor. I just wanted to learn as much as possible about what he was going to do. He gave me a general estimate and he explained that he would need to get an engineer involved, for the permitting process. This was because my foundation did not have a sil. He explained that it would be a few months before his company would actually be able to perform the work. That was fine with me. The estimator and and workers were on time, completed the job, cleaned up their messes.
Description of Work: Seismic retrofitting for my 1926 home. Most of my home did not have a sil. The foundation seemed to have been installed after the house was constructed. This meant that they had to involve an engineer. My home is small. The footprint of my house is about 800 sq feet.

They were loud as one might expect working with jack hammers. They were pleasant and they left everything very clean, with fresh plastic sheeting over the area of the basement that was unfinished. Retrofitting is very important in this area. We selected Jackson because they have a long-standing reputation for being the go-to firm for retrofitting. We can only hope not to have much occasion to check on the effectiveness of the job.
Description of Work: My mom was alive and suffering lung disease upstairs. It was very necessary that they make sure that dust was not filtering into her breathing space. They did well in that regard. It was our understanding that they would spend at least two or three days on the job, but finished in one - which was surprising. The City Inspector was most surprising in spending about two minutes running to the basement, signing his name and off again. Not free so - still wonder.

Thank you very much for your comments. I am happy that we did a good job with our dust control and cleanup. I wish we could do more about the noise we make, but unfortunately that is the nature of the business. Regarding the very quick building inspection, I suppose that is partly because we enjoy a very favorable reputation with the inspectors. They have been seeing our work since 1999, and I like to think that we always do quality work. They don't exactly "rubber stamp" the inspection report, but they probably don't scrutinize the work as closely as they might with a contractor they don't know. Sincerely, Leif Jackson, owner

We were completely satisfied with how this work was completed. Leif Jackson, the owner of Sound Seismic, was an effective educator, helping us to understand what a retrofit entails. We had a preference for when the work would be scheduled (both the start and ending dates) and he assured us he'd be able to accommodate our need. His bid for the work was the lowest of the three we received, and the enthusiastic comments of several of his former customers helped us make the decision to contract with his company. Matt, the lead carpenter, did most of the work and was excellent. He was punctual, eagerly answered our questions, and completed the retrofit and deck projects within the projected time frame. Mike, another Sound Seismic employee, assisted Matt on one day, and he, too, was professional and competent. Leif visited the site on the first day to assure himself that the work was proceeding as planned, and later consulted with Matt when an unanticipated difficulty came up with the deck-leveling. I was particularly impressed when I learned that Leif had vetoed a "short cut" that had made sense to me, insisting that a more expensive and extensive "proper" way of resolving the difficulty, with no additional charge to us, be followed. The precision of their work, the professionalism of their staff, the fact that the work began when it was scheduled and was completed within the planned time frame, and the care they gave to our home and the landscaping all converged to earn a top satisfaction rating from us.
Description of Work: The earthquake retrofit of our mid-1940s two story home required some decisions. The basement laundry room and a nearby storage room gave easy access to the foundation and the mudsill, so in those areas completing work in the house interior was the best option. For other interior areas, e.g., a finished room and the garage, access to the foundation and mudsill were blocked by drywall, ceiling tiles, and heating ducts. Leif Jackson, the owner, educated us about the engineering requirements and choices available to us, and we ultimately decided that a combination of interior and exterior work would work best. Removal and reattachment of two courses of siding was necessary for the exterior work. Repair of a sagging front deck was a second element of the contract. This project involved supporting and raising the deck framing, removing and replacing existing beams and posts, and installing brackets. Finally, while the above work was underway, we asked that one additional task be completed. A plywood wall under the front deck needed to be replaced.

We wanted to have the necessary earthquake retrofitting done to qualify for earthquake insurance. After talking to our insurance company and doing research on the internet, we found Sound Seismic to be highly recommended. I contacted Leif and setup an appointment for him to perform an evaluation and estimate. Leif arrived at the time scheduled and provided very detailed information regarding what is involved and required by the city. He even later sent me a PowerPoint presentation he had put together providing more details on earthquake retrofitting. When the estimated start date got closer, I had to contact Leif a couple of times to confirm the start date. Once the official date and time were set, Matt from Sound Seismic showed up on time and went right to work. He estimated the project would take 2 to 3 days, which turned out to be accurate. Matt was very good at providing progress updates throughout the duration of the project and after the first inspection was complete. The crew also did an excellent job cleaning up after each day and keeping dust to a minimum. After the second inspection was complete and the project signed off by the city, I asked the inspector his opinion of Sound Seismic, and he said they are one of the best, which just strengthened my confidence in the quality of work performed.
Description of Work: Performed the necessary earthquake retrofitting of our home to meet insurance qualifications. This included the installation of sill blocking, anchor bolts attaching the mudsill to the foundation, framing as necessary for shear panels, metal framing angles for first floor / pony wall attachment, insulation in the pony wall stud cavities, and structural plywood shear panels. We also had them install a Northridge automatic gas shutoff valve.

Erik was very helpful. The estimate was not detailed and it was much higher than the others I got. There was no way to compare the estimate to another because only the final price was given. If it wasn't so high I would have gone with them since they seemed to be a very trustworthy and ecological company.

Thank you for the feedback. I wish we had a chance to answer questions about what was included in our price. As a general contractor (rather than a countertop specialist), we consider everything involved in a project like yours. It would have been interesting to see if the "much lower" numbers included lead-safe precautions, backsplash, caulking and painting, etc. Best of luck with your project.

They did an excellent job. The whole experience from start to finish was excellent. When they came out they told us what would need to be done, how it would be done and how much it would cost. We set a date and they came. They did the work exactly as they said they would. There were no surprises. The communication with the contractor throughout the process was excellent. The crewmember that came out to do the work did a fantastic job of cleanup afterwards. It was just excellent from start to finish. Because of the work they did we were able to get earthquake insurance, which we had not been able to qualify for previously. We would use them again and we would recommend them to any of our friends.
Description of Work: We used Jackson Remodeling Sound Seismic to do an earthquake retrofit project which required an engineered solution so it was a little more technical than it might have been otherwise if we had a newer home. We have a 1928 home that required some special engineering to do it. They bolted the house under the foundation and put up sheer walls.

They were professional and they came when they said they were going to come. They came early and they called me to ask if it was okay to start the work earlier. They explained everything to me. It seemed like a reasonable price for the work because I looked at other people?s descriptions on retrofitting on Angieslist. The price seemed right in line with what I was expecting.

My experience with them was very good. They were upfront about the work that would be needed to be done, about the cost and about the specific changes that would be required. In general, they had a high level of professionalism. They were on schedule, did a good job and cleaned up afterwards. They actually returned calls, which seems to be rare with contractors. I haven?t had other work of this sort done before. They did a really good job overall. They were very good about scheduling and estimates, and did quality work. They were one of the few providers in the area who would do the work - I thought the price was reasonable. I would use them again in the future.

I can't assume that they'd be very responsive during construction, considering their rigidity during initial contacts.

True, we work during work hours and spend evenings and weekends with our families. If keeping regular hours like almost every other profession = "rigidity", then we are guilty as charged. I regret that the member would post an "F" report based on this one policy. And his projection about how that would reflect on our responsiveness during construction is absurd. 99% of callers are willing and able to schedule an appointment in the morning or on a day off with minimal disruption to their schedule. When that is not possible, we do make exceptions to accomodate our clients' needs.

I wish to praise SOUND SEISMIC for the earthquake retrofit they completed on my home. From the estimate to the finished job, Leif, Ryan and Jesse were professional, hard working, pleasant and exceptionally CLEAN. They handled the permit and inspections seamlessly. Office support from Elizabeth was equally professional, reliable and fast. I can't describe everything so I'll just say the whole experience was great.

On Feb. 27,2009 Ryan and his helper arrived on time and got started on this, structurally engineered and contracted job. It was estimated to take approximately one week to complete this work. The job was completed on Mar. 5 with great professionalism and dedication to the work completed. The work passed a city inspection with no additional work required. The quality of work is excellant with attention to detail.
Description of Work: A requested inspection,by me, by Sound Seismic indicated that our home was not adequately secured to the foundation (eg.: very few,widely spaced, rusted bolts,no nuts, in oversized sill holes, and a 'suspect' pony wall ). Sound Seismic recommended a Seismic Retrofit to reduce the likelihood of the house sliding off the foundation or a pony wall collapse during an earthquake (note:this is seismic zone 3 country ). Our home, built in 1977, is two story with a crawl space.

They had to sub contract a company to do some repairs to the basement and that company didn't do a good job. Although Seismic did a good job on their part, they weren't very helpful when dealing with the sub contractor in order to satisfy us and that is the reason I wouldn't hire them again. Their price was average and there was some confusion in the scheduling. They brought a portable potty and it took them two weeks after the work was done for them to pick it up. I wouldn't recommend them because I think there are better companies out there.
Description of Work: Sound Seismic did a seismic upgrade, which means they went around the perimeter of my three bedroom and two bathroom home s foundation fastening some brackets from the concrete into the wooden sill plate to attach the house to the foundation. They finished in four days.

Based in Ballard, the 2 man crew of Sound Seismic did a very clean, professional job of installing the earthquake retrofit. I was very happy with quality of the work and the way the crew kept the site clean and organized every day. They stick to a firm 8-hour work day for their employees and offer health benefits, a rarity in the contract world, it would seem. So their bid was not the lowest, however was comparable to a number of other firms, within 5-10%. Very punctual and professional in all coordination and in handling the 2 inspections reqd. by the city. No surprises or additional costs. I would recommend this contractor overall.
Description of Work: Sound Seismic. We had our old post-war 1946 house retrofitted for earthquakes. Following a standard formula for old houses, Sound Seismic added anchor bolts to tie sill plates to the foundation, bracing clips for the rim jousts, and plywood bracing to re-reinforce the pony walls in the daylight half of our basement. I drew the plans and got the Seattle building permit myself, Sound Seismic performed the work (house is relatively small, 1050 sf).
