"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."

I value all of my customers & follow all of my projects from start to completion to ensure rigid quality standards, I believe in doing things right the first time. I generally handle projects on my own, sometimes with a helper. When I have a larger project, I have a solid network of contractors that I sub-contract with. I generally request approximately 50% down payment on most jobs for new customers, but that can vary depending on project scope, materials, etc.., remainder + tax due upon completion. At this point I accept cash or check. I estimate projects, or charge time & materials. I value communication with my customers to ensure everyone's needs are being met & we're all on the same page. I have a $200 minimum charge which covers the first 2 hours on your job, then it's $50/hr from there on. The minimum charge ensures overhead is met on any job. Crawl space & attic work incur extra charges. Welding & metal fab is billed at a higher rate, depending on the project. I guarantee all of my work & proudly stand behind my ethics & performance. You can always find someone cheaper, but why pay for something twice? Get it done by a qualified person, done right the first time.
