You all were wonderful. Who knew working in a house while folks drilled concrete was going to be the best experience of the pandemic. 

Mary Catlin, Capitol Hill

If only working with all construction trades was as easy as it is with Sound Seismic... They're very transparent, professional, had great communication before and during the project and did a great job with our mostly unfinished and open basement.

Sara Raymond, West Seattle

Monte and Angelo did excellent work for us on our earthquake retrofit project. They were professional and efficient. Several of the placements of the plates that they bolted into the foundation were in tricky locations, and they installed them without any nicks or damage to the surrounding pipes, wires, or garage door. Monte and Angelo, as well as the project manager, John, communicated well and kept us informed throughout the project on their progress. Following their installation, the drywall installers did a seamless job patching things back up. We were very happy with Sound Seismic!

Daniel Stonington,  Beacon Hill

 

We hired Sound Seismic to retrofit our older Seattle house. We were thrilled with the service, communication, and professionalism of the company, especially our two contractors, Monty and Angelo, who went above and beyond to transform what might have been a daunting house project into a positive experience. They were excellent at communicating, sending us detailed, thoughtful texts daily to let us know their arrival and departure times, and though the work is loud (not their fault, of course—that's the nature of the project), they worked SO clean that I didn't notice dust anywhere upstairs. They were also extremely warm and friendly that my daughter baked them cookies one day. I highly recommend this company, not just for the peace of mind a retrofit provides, but for the wonderful experience they provide.

Emily Cherkin, Ravenna

 

Simply one of the best companies that I have worked with. As an Earth Scientist that specialize in earthquakes hazards, Sound Seismic exceeded my expectations for our home seismic retrofit. Sound Seismic was a pleasure to work - super competent, very knowledgeable, and professional.

Charlie Rubin, Capitol Hill

One of the architects we met with recommended Sound Seismic to retrofit our 1927 home. The owner, Leif, came out and gave us a thorough walk through of what it would involve, and they were able to fit us in earlier than expected due to an opening on their schedule. The crew came on time everyday, communicated daily when they were leaving, and left our house immaculate. They do great work and you'll be happy to use them to safeguard your house.

Jessica Tai, Ravenna

Everyone at Sound Seismic was very professional and courteous. John was our main contact, and he was great at keeping posted on progress, and followed up promptly whenever we had a question. And the workmanship was great. Thank you!

Brian Utting, Ballard

Sound Seismic has a good system down. From the walk-through, to contract, engineering design, permits, and install. It was pretty fluid start-to-finish. I'd hire them again for our next Seismic Retrofit.

Kenny S, Wallingford

Seismic did an earthquake retrofit in our crawl space.  Excellent work and timely.  When an issue arose, they were quick to make it right and we’re very professional handling it.  Would highly recommend them.

CM Miller, Lake City

Very professional, kind and competent work. I’d recommend them to anyone looking for seismic retrofit work.

Emily McMahon, West Seattle

Sound Seismic retrofitted our home recently and did an excellent job. They were on time, on budget and their professionals were great to have in our home. They followed Covid protocols and we felt safe. The finish carpenter was precise and skilled. Sound Seismic had the engineer design the needed retrofit, obtained the permit required and coordinated the city inspection. It was seamless. We had to wait for their estimate and the beginning of the project but a wait well worth it! They showed up for every appointment and work day on time and worked complete days. I’d highly recommend them.

Jan Chiles, Phinney Ridge

The folks at Sound Seismic were so easy and professional to work with, everyone from the folks answering phones to the people who came out to give us an estimate, to the actual folks who came to retrofit our house. (They even squeezed through our tiny craw space entrance, which we had worried would be inaccessible.)

Honestly, just check out their website. I didn't look anywhere else after getting such a trustworthy vibe from the website. They were quick and efficient and it's so nice to know that our little house is a little better prepared if we're hit with a quake. Thanks Sound Seismic!

Andi Newman, Burien

I am so happy with the work and professionalism of Sound Seismic. It start with Leif, who did the initial consultation. He explained exactly what his company did and what he recommended for my house. When I asked for alterations to the contract he was accommodating. When I asked him questions, he explained answers thoughtfully and thoroughly.

John the project manager was very good. He stayed in touch throughout the project, and was very responsive. He offered to take away a set of old closet doors that I was meaning to dispose of because they had room in their dump truck. When I found some debris that had been missed during cleanup, he came over the same day and collected it.

Monte and the construction crew did a great job with the earthquake retrofit. The crew wore masks all the time, even outside while they worked, and were professional and friendly at all times. Monte arrived between 8:30 and 8:45 every day. If he couldn’t make it by 8:30, he texted me in advance explaining why (e.g. line at the lumberyard). My neighbor told us that she wished her contractor was that reliable!

I am so happy with the level of work that they did, that I want to use Leif’s remodeling company to do our remodeling project. Thank you Sound Seismic!

Andy Haldeman, Shoreline

I had an excellent experience working with Sound Seismic. They did what they said they would do, when they said they would do it (even though there were weather challenges), and at the price they initially quoted. The process was very transparent, predictable, and consistent. The installation team was on the same page as the project manager, who was on the same page as the person who assessed and quoted the work. Sound Seismic implemented an engineer approved solution, dealt with the permitting and inspections, and provided full documentation when the project was complete. This was meaningful to me since I received quotes from other contractors for this work. The difference in approach was huge. It was clear that Sound Seismic had a much deeper understanding of the work that needed to be done compared to other contractors. While their bid was not the lowest, it was in the same range and the additional value they provide was clear. Sound Seismic also did a good job checking in with me at the end of the project to make sure I was happy with the work and that my questions were addressed. I would recommend Sound Seismic to anyone who needs an earthquake retrofit.

Julian Sell, Madrona

Mary Ellen and I are both extremely pleased with the work that your crew did.  Please pass on my personal "thank you" to each of them. 

We were pleased with the amount of clean-up that was done at the end of each day.

Even with your discovery of unforeseen conditions that necessitated additional framing, it was still done within a very reasonable time-frame.  My overall experience with Sound Seismic has been very positive and we will recommend your services to our circle of friends and family.

Again, thank you for a very "enjoyable" experience!

Mark and Mary Ellen Whitesell, Ballard, Seattle

I wish to praise SOUND SEISMIC for the earthquake retrofit they completed on my home. From the estimate to the finished job, Leif and his crew 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.

Kristin Hill, Wallingford, Seattle

Sound Seismic was 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 had read other people’s descriptions on retrofitting on Angies list. The price seemed right in line with what I was expecting.

Sarah Morken

The crew kept me informed of their progress and plans all the time.  They told me what their plans were, and delivered every time.  Very satisfying knowing I could count on them doing what they promised - when they promised it!

Martin Muller, Olympic Manor, Seattle

Sound Seismic was the most professional group of contractors/employees I have ever dealt with. They were knowledgable, dependable, and skilled. The project lead was obviously well trained and knew what he was doing, was able to effectively manage and direct his crew and subcontractors. A quality job. Discovered an area behind my walls were my house was not up to code. Worked well will me to correct the problem and professional and reasonable about the change order.

 
Andrew Austin, Phinney Ridge

The Sound Seismic crew 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 in 4 days 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 excellent with great attention to detail.

Leon Young

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.

Jennifer Dovey, Broadview, Seattle

Sound Seismic did such a thorough job. Looking at their work lets me sleep better at night knowing my house is now very unlikely to shift off its foundations in an earthquake.

P. Kiraly, Madrona, Seattle

We thank you for the very professional work done by all of your people that we have had contact with.  The crew working here were outstanding, and we were charmed by your lead carpenter, Matt. 

Our basement has not been this clean in 70 years (the house is 70 years old)!

Thanks again,

the Pearsons
Bryant neighborhood, Seattle

My experience with Sound Seismic was very good. They were upfront about the work that 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.

 
Karl Bystrom

We recently had Sound Seismic do our earthquake retrofit. I cannot compliment enough the very professional job they did. Leif Jackson, the owner, sat with us for two hours answering questions and explaining how earthquakes work. He was completely above board, not promising more than he could deliver. He left interesting reading material so that we could evaluate and decide for ourselves. The most compelling was from FEMA warning people in the Puget Sound area to do everything they could to protect their homes because of our earthquake risk.

Once we were in contract, Leif sent our information to a structural engineer who drew up the plans. The bid was fair and complete. The crew showed up on the date the job started and completely it quickly. It looks great. Our new pony walls are gorgeous and the bolts and clamps very reassuring. City inspections were completed for the bolting and then for the finished job. This company is certified and high quality. Our house will be sticking around on the foundation. I encourage you to get over gambling about retrofitting and hire these guys. They are great.

Emily Elliott, Queen Anne

We had a wonderful experience with Sound Seismic.  After the devastating earthquake in Japan my husband and I were quite worried about our 3 story brick home and decided to retrofit our basement as a way to ease our anxiety and protect our family.  

Sound Seismic's estimate was more reasonable than any of the others we got and we felt very confident knowing that Leif and his team have done many retrofits, including our friend's basement.  Leif was able to explain the process to me, answer my questions, and gave me the estimate within an hour of coming to the house.  

The hardest part of the process was moving our furniture and boxes out of the way to prepare the basement - after that things just moved along smoothly.  I had been expecting huge holes in the walls and dust everywhere but the work was really tidy and not nearly as disruptive as I had feared.  My kids and I were able to stay in the house the whole time, only playing out in the backyard a couple times when the banging was loud.  The baby was even able to take naps in the midst of the demolition!  

Matt was very professional and friendly, he always arrived on time and he communicated well, checking in with us at the end of each day to show us the progress of the work.  He was able to finish the work a half-day sooner than planned and there were no hidden costs or extra changes when the invoice arrived.  

I would highly recommend Sound Seismic to anyone -- they were fantastic!

Rachel Opel, Ballard, Seattle

"Leif

Thanks for the great work on the house - you've done an outstanding job of prompt, low-impact work - and leaving the job site in excellent shape. Appreciate the attention to detail."

Wayne Dodge, Ravenna, Seattle

"I wanted to follow up and thank you for your good communication, strong planning and flexibility.

Your foreman was great. Very professional, low key, friendly and efficient."

Urs Koenig, Madrona, Seattle

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.

George Murphy, Northgate, Seattle

Sound Seismic gave a very competitive bid, clearly explained everything they were going to do, accomodated my schedule, and produced a very high quality outcome.  I highly recommend them.

Gary Johnson, Wallingford, Seattle

Dear Leif,

Your crew did a great job!  It was a pleasure to meet them. And as soon as I met your lead carpenter, I knew that everything would be done 'right.' 

They took extra care at every level: and left everything better than ever.  They were able to remove the siding without cutting it, which is great, too.

I am glad that I got to see how substantial the anchors, fasteners, etc. are - and how robustly the plywood panels are nailed in. ( It was hard for me to tell from the blueprints alone.)

I am very happy with all aspects of the plan and the work, Leif. 

David Rosenbaum, Sand Point, Seattle

All in all, we felt the project went extremely well.  Given the number of earthquakes worldwide of late, we are pleased to have had the work done.  We’d rather not have it tested, but we know we are in as good a position as possible if the ground starts shaking!

Barbara E., Capital Hill, Seattle

I wanted to let you know what a great job that your crew did on our earthquake retrofit.  They were very knowledgeable about the whole process and answered any questions we had without hesitation. Their work was excellent and they finished the job quickly.  I have done my share of remodeling in the past and I can say that they cleaned up after each day’s work more thoroughly than anyone I’ve ever encountered.  They took obvious pride in the retrofit work they did but also in the cleanup. They saw that as an integral part of the Sound Seismic service.  All in all, it was a fast and painless experience.

Thanks for assigning those fine young men to our job.

Paul Gustie, Fremont

Sound Seismic performed an engineered retrofit on our house built in 1928.  I've never had a better experience working with a contractor - thoroughly professional (truly experienced and knowledgeable in their craft), they were also excellent communicators throughout the engagement.  And the cleanup afterwards was amazing.  I would recommend them without reservation!

George Murphy, Northgate, Seattle

I wanted to thank you for the wonderful job you did retrofitting my home in South Seattle. I was aware that it would be a challenge and it proved to offer more problems than we expected. You met them all and did a great job correcting the rot and damage that happened over the years since 1927, when the house was built.

When I arrived home yesterday the basement was clean and organized. It was the first time I did not have to spend hours cleaning up after a contractor. Your lead carpenter and his assistant were a great team. Thanks for all your efforts.

Regards,

Patrick Murphy, Mount Baker

I can't think of a single way you could improve the service of your company.  Yours is one of the VERY best companies I've worked with on this home.

Jeannie Macri, West Seattle

Sound Seismic completed a earthquake retrofit on our house. Their explanation about what to expect and what we'd get was clear and straightforward; the work was completed as described, as scheduled and exactly on time; clean-up: spotless.

Harriet B., Ballard

"The experience with Sound Seismic was possibly the finest I have had in my dealings with any of my trade contractors. Your crew was knowledgable, well informed, hard working, tidy, as well as a pleasure to have on my job."

Jesse Lee Honor, Project Manager, Northwest Homecrafters

Thank you very much for your excellent work on retrofitting our house.  We appreciated your careful oversight of the project, ongoing contact with the engineering firm, attention to detail, and clean and timely work.  You really rose to the challenges presented by "this old house."

Mike E., Capital Hill, Seattle

Sound Seismic exhibited a great combination of skill, hard work, and professionalism.  You treated our home and our project as though you were doing it on your own house.

Linda and Rick T. Kirkland, WA

Everything looks good. Thanks for the all the work your guys did, very professional.

Cheers,

Stuart Jamieson, Montlake

Sound Seismic did an excellent job of the seismic retrofit on my two-story house, which entailed quite a lot of siding work as I don't have a basement. The workmen were punctual, neat and meticulous. I feel safer because of their work.

Pippa Kiraly, Madrona

Just wanted to send you a note to express how pleased we are with the work your firm recently completed.  You did exactly what you said you would and the quality of the work is first rate.  Also, please tell Matt how much we enjoyed him.  Thanks,

Gary Johnson, Wallingford
 

Highly recommend Sound Seismic! They know this business inside out and have been doing homeowner workshops for years. They were able to tailor the techniques to our quirky basement and explain every detail of what they were doing.
Manny was a pleasure to work with - he texted us every morning to let us know he was on his way and made sure we understood the work.
