Drew Guthrie — Owner & Lead Estimator

Background

I started in construction on my grandfather's crew when I was 16 — hauling materials, pulling demo, learning the trade from the framing up. That's three generations of Guthrie builders working Southern California homes: my grandfather framed tract houses in the 1960s, my father ran remodels through the 1980s and 1990s, and I grew up on those job sites before stepping into my own work in the early 2000s.

That's 22+ years on my own count, and a lot longer than that if you count the years I was holding the other end of a tape measure as a kid. The trade isn't abstract for me. When I quote a window retrofit on a 1988 Paloma del Sol tract home, I've probably installed on a dozen of the same floor plan — I know where the headers run, where the stucco cracks hide, and where the original sub-contractor cut a corner three decades ago.

Service route

Temecula is home base and always will be. My 75-mile service radius runs north through Murrieta, Menifee, Wildomar, Lake Elsinore, and Hemet; west into Fallbrook and Escondido; and south through San Marcos, Vista, Carlsbad, Oceanside, Rancho Bernardo, and Poway. I drive this route every week, not occasionally. Temecula Windows & Doors is a service-area business based in Temecula, CA — we don't have branches, we have trucks and a route.

I meet every homeowner in person for the measure visit. It usually takes 30-45 minutes, runs the spec sheet, photographs every opening, and lands a written quote in your inbox inside 48 hours. On the install day, I'm on site for the start of the job and back for the final walk — the same faces you met on the measure are the ones in the driveway on day one.

What "no subcontracted middlemen" means in practice

Most Southern California window and door companies sub out their installs. The salesperson you meet isn't the installer, the installer isn't the project manager, and when something goes wrong the three people you're trying to coordinate don't work for the same company. That's where jobs fall apart.

My crews are in-house. Same four people across every Temecula Windows & Doors project in Temecula, Escondido, Fallbrook, and the rest of the service area. They carry W-2s, not 1099s. They know the brand spec sheets we install, they know the $ Riverside County and San Diego County permit path, and they answer to me, not a subcontracting middleman. That's the workmanship warranty you sign — two years in writing on top of the manufacturer's limited lifetime on the glass and frame, with the same crew accountable on day one and day 700.

Why I started Temecula Windows & Doors

Family name on the truck means the crew shows up the way it would show up at my own house. That's the short version. The long version is that after too many years watching sub-contracted installs go sideways, written quotes become loose estimates, and homeowners left to chase warranty claims on products the installer didn't actually install, I wanted to run a company where that didn't happen. So Temecula Windows & Doors is run that way — the measure, the quote, the install, and the warranty all live under one roof, and that roof has my name on it.

Most of our work comes from referrals. That's the feedback loop I trust. If the neighbor two doors down liked the install, the next call comes from that block. We don't run a big ad budget, we don't have a call-center salesperson writing generic quotes, and we don't pretend to be a national franchise. We're a local Temecula window and door shop with a 75-mile route and a customer list that keeps growing by word of mouth.
