Mark Lim, after the Eaton Fire. January 2025.

Why RF1 exists

“In January 2025, I lost everything I owned to the Eaton Fire.”

My home, my memories, my sense of security. Afterward a friend asked me a simple question: what if we could help other families avoid this? That question became Ready Fire One. Preparedness shouldn't be a luxury, and nobody should have to figure it out alone.

What we do

Protecting a house means a dozen contractors and a pile of rules. We make it one call.

Vents, roof edges, the first five feet, fencing, inspections and insurance forms usually mean a different contractor for each. RF1 is the one team that runs all of it, from the first walkthrough to the final photos.

Real RF1 jobs

Small upgrades, fewer ways in.

Most of the work is unglamorous: the vents, gaps and first five feet that embers find first. These are from our own jobs, shot on a phone. Swipe to compare.

The things people ask us first.

The assessment is free. Most jobs land between $500 and $5,000, depending on how many fixes your home needs and how hard they are to reach. Your plan lists a cost range for each fix, highest protection per dollar first, so you decide what to do and when. Nothing gets scheduled until you say yes.

Don't wait for the next red flag day. Start with one call.

A free assessment, a plan with prices, and one team to do the work. Pasadena, Altadena and across Southern California.
