Our happy and satisfied customers recommend us to their friends and family all the time. We are proud of our reputation and we feel it has been well earned. We are also happy that we can help you feel good knowing that you are working with a reputable company that stands behind its products and services.
"I hired Secure Seismic to do a retrofit of my single story ranch built in the 1970s. Though I'm in the southern Willamette Valley and a ways from Portland, Daryl came down to give me a free estimate. Secure Seismic came in below their competitors and Daryl discusssd the plan with me in depth. Based upon the quality of the reviews, I hired Secure Seismic. They scheduled out within a couple of weeks. Johny the foreman kept me on the loop while they were at my house. They completed the job within a day and left the site clean. Pieces of drywall cut for access in the garage were thoughtfully replaced and will take little effort to clean up. Thanks for great work! I already sleep a little better knowing that my house will likely be okay when the big one hits."

Neil Kelly Company
Neil Kelly Company
Neil Kelly is the largest design-build remodeler in the Pacific Northwest, offering remodeling, home improvement and solar energy services through our design centers in Bend, Eugene, Portland and Seattle. For 75 years, we’ve been building a reputation for designs, outstanding craftsmanship, uncommonly good service, and consistently satisfied clients. We are a pioneer in the design/build process in the Northwest and strive to incorporate green design and remodeling elements in all our practices.
"BEWARE. It has been nine months since we engaged Neil Kelly, our project has slipped to December. Neil Kelly's most recent activity was the May completion of an overly expensive demolition. It took over five months to receive design renderings and pricing. The summer was filled with poor communication and missed commitments. A myriad of mistakes were made in almost all components related to our scope of work, it was filled with errors. We had to find and ask for corrections, as Michael Johnsons work was incredibly sloppy. Work done on exterior staircase/handrail was shoddy, as the rail fell off when a person weighing 145 pounds used it to access the area. (We paid $9,000+ for a rough stair structure.)We paid a deposit to start Phase 2 of 3 to build-back in June, last week we got an email from NK after reaching out again for an update, saying that our job might begin in December they are spread thin! To date no permits have been pulled; no vendors were contacted. We have asked for our deposit back Ironically, it was one of the first times their response was prompt with a NO!"
