How soon can you start my job?

"We’re usually booked a month or two in advance, and our lead time is typically two to four weeks. We may be able to start sooner depending on our schedule and the availability of materials required for your project."

How long will it take to complete my project?

"It depends on various factors, but we’ll give you an honest time estimate before work begins. Quick projects can take as little as a day while some commercial projects can take weeks. Generally, a custom staircase and handrail project, which is the bulk of our work, takes anywhere from one day to one week. Painting, staining and finishing may take more time. However, once we start your job, we’ll stick with it until it’s done. We don’t start jobs and then leave them to work on other projects."

Can you give me an estimate?

"Yes. We’ll visit your home; measure the area; and give you a customized estimate based on the design, configuration, and upgrade options you choose."

Do you require a deposit?

"We don’t require a deposit for most jobs. Some larger jobs require a deposit, but it’s only collected after the materials are delivered."

Can I use my staircase while you’re working?

"Yes, you’ll be able to walk up and down your stairs, even if we’re working on the steps themselves. In fact, we usually do one section at a time so the whole staircase doesn’t have to be torn down. As long as it’s not open or dangerous, you’ll be able to use your stairs as you normally would."

Taro Martinez: Stair Man

By James Florence, Diamond Certified Resource Reporter

Taro Martinez used to be an auto mechanic, but when he got tired of that livelihood, he decided to take a step in a new direction. “After owning an automotive repair shop for several years, I needed a change in both career and scenery, so I moved from Los Angeles to Northern California,” he recounts. “Soon after my arrival, I was offered a job with a staircase builder. I’d never done any work like that—I doubt if I’d even cut a ...
